Roborock Qrevo Slim: two-minute review

Although sporting a lower-profile design than some rivals, the Roborock Qrevo Slim is otherwise a full-size robotic vacuum and mop that is powerful, intelligent and packed with features. The redesigned LiDAR system means it can slide more easily under low furniture, getting to floorspace that other robots can't, without any noticeable compromise in navigation performance.

The well-appointed Roborock app serves up no fewer than five suction levels, plus configurability for the cleaning route and mopping performance. It also smartly raises its dual spinning mops when carpet is detected, and features a spinning side brush that pivots outwards to reach into the corners of every room.

With up to 11,000Pa of suction power, the Qrevo Slim is more powerful than many rivals, including the pricier Eufy Omni S1 Pro, and you can even view a live stream from the front-facing camera in the Roborock app, turning the vacuum cleaner into a pet monitor.

The Slim does not feature the bouncy 'AdaptiLift Chassis' found on the Roborock Qrevo Curv, which launched alongside the Slim in September 2024. However, perhaps thanks to the improved navigation system, the Slim robot itself still tackles thick rugs and raised door thresholds with a confidence missing from most rivals. It's also worth noting that despite the low profile, this is still a relatively large robot, with an equally large docking station, so it's best-suited to medium and larger homes. That's the short version; read on for my full Roborock Qrevo Slim review.

Roborock Qrevo Slim review: price & availability

• List price: $1,399
• Launched: September 2024
• Availability: US

The Qrevo Slim launched in September 2024 and sits in the premium price bracket. It comes with a list price of $1,399, but you might be able to avoid paying that – I've spotted it discounted to around $999. At time of writing (because this market moves fast!) it sits at the top of Roborock's Qrevo range at, which itself occupies the middle tier of the company's robotic vacuum offering.

Below it you'll find the budget Q Series, and above you'll find the flagship S Series family, where prices start just below the Qrevo Slim (you'll pay $1,300 for the S7 Max Ultra), and extend all the way up to the range-topping, $1,800 S8 MaxV Ultra.

A four-figure vacuum may sound expensive, but that $1,300 buys you a lot of smart technology, and in this case your money goes into an interpretation of LiDAR known as 'StarSight', which is unique among robot vacuums, and is responsible for the Qrevo Slim's reduced height. You also get very high suction power – and in fact, at 11,000Pa, the Slim is more powerful than even Roborock's flagship S Series, which peaks at 10,000Pa. For comparison with other brands, the equally expensive Eufy Omni S1 Pro is rated at just 8,000Pa.

There is no ongoing subscription cost for the Qrevo Slim, although you'll need to purchase replacement dust bags every couple of months (Roborock says they get full in about seven weeks), and the side brush and mopping pads will eventually need replacing too.

Roborock Qrevo Slim review: design

• Low-profile design fits under furniture
• Self-cleaning and emptying charge dock
• Dual rotating mop pads

The ‘slim' part of this robot's name refers to how it doesn't have a spinning LiDAR sensor on top. This makes it shorter than most rivals, and at 8.2 cm tall it can drive places other robotic vacuums cannot. Roborock has replaced the conventional LiDAR sensor with a system it calls StarSight. This includes a dual-light, solid-state LiDAR system, plus a 3D time-of-flight sensor, a camera and infrared sensors. (Head to TechRadar's article on how robot vacuums navigate for a deep-dive into this area.)

The rest of the Qrevo Slim's design is similar to other self-cleaning robovacs in the Roborock range. The robot is circular, with dual spinning mops at the rear (this style of mop is typically better at scrubbing than the fixed, D-Shaped pad style), a rotating brush at the side that cleverly extends to reach into corners, and a pair of rotating rubber brushes underneath. The charge dock has a dust bin and a pair of water tanks – one clean and one dirty – to work with the robot's mopping function.

The robot itself measures 350mm (13.8in) wide, 353mm (13.9in) deep and 82mm (3.23in) tall, while the dock is 340mm (13.4in) wide, 487mm (19.2in) deep (including a ramp the robot parks on) and 521mm (20.5in) tall, although you'll need to leave space for the water tanks, which are removed by lifting them upwards from the dock.

Roborock also sells the Qrevo Slim with a refill-and-drainage system. This works in the same way, but plumbs into your home's water supply, so can refill and drain the mopping water tanks automatically. This dock is the same width and depth, but is shorter, at 405 mm (15.9in). For this review we're looking at the regular model with the larger, manually-refilled and emptied water tanks.

As with other such robots, the Qrevo Slim dock charges the robot's battery and empties its dust bin into a larger bag that Roborock says only needs changing every seven weeks, although that will vary depending on what you're asking it to pick up. The robot also has its mopping pads cleaned with warm water and dried during charging, while the onboard water tank is emptied into the dock.

Back to the robot itself, and the Qrevo Slim can automatically lift and lower its mops, depending on the floor surface and what cleaning task is required. The side brush and one of the spinning mops can also move outwards, touching the walls and skirting boards for a complete clean.

There are three buttons on the top of the robot for quick access to key functions, like powering up, pausing and sending it back to its dock. Removing the magnetic cover gives access to the dust bin and filter, which can then be removed and cleaned or replaced.

The robot and dock take up a fair bit of space, and it's recommended that you place the dock against a wall, but with enough space either side for the robot to drive into, ensuring it cleans every last bit of your floor. You don't have to do this though, and you can sit the dock in a corner if needed; just make sure the ramp is clear for the robot to drive onto.

Roborock Qrevo Slim review: performance

• Handles thick rugs and raised thresholds with ease
• Automatic switching between vacuum and mop
• Cleans deeply and reliably

Right away, I want to highlight how good the Roborock Qrevo Slim is at driving through thick rugs and over raised doorway thresholds. These are both tasks other robotic vacuums can really struggle with, and even flagship models with four-figure price tags have failed to clamber their way from my exposed-floorboard hallway into the carpeted bedroom.

Not the Qrevo Slim though. It drove over every threshold, every time. It even managed to wade its way through a thick rug in the lounge – something no other robot has achieved reliably – during its first exploratory drive. During that drive it used its camera and imaging sensor to create a map of my flat, which it automatically split into labeled rooms. It got most of the labelling correct, but I still had to jump into the app and make a few edits before saving the map.

Its off-roading abilities meant I could leave the Qrevo Slim to get on with its job, safe in the knowledge that it would drive into every room, clear the rug (and automatically vacuum it, too) and return to base without me checking if it had got trapped. On a couple of occasions, it briefly got stuck on a raised threshold, but always managed to clear it by reversing and driving forward again at a higher speed.

The automatic mode selection also impressed me. Since it's so often a challenge for robotic vacuums, I usually roll the rug up and set a robot to mop and vacuum the wooden floor. But with the Roborock I left it to do its own thing, where it vacuumed and mopped the wooden floor, then automatically raised its mop to vacuum the rug, before lowering it again to continue mopping the floor and ensuring the rug stayed dry.

As well as recognizing the difference between floor types, and where each room ends, the robot can also spot common household items like beds, sofa and television stands, which it then adds to the map.

On test, the Qrevo Slim's navigation was usually very good, driving confidently into small gaps, not crashing into anything at speed and not getting stuck. But on one occasion it got confused and failed to find its way back to the dock. Understandable if it was stuck under the sofa, or somewhere else far from the charging station, but it was just a foot or so from the dock, yet after lots of spinning around it declared defeat via an app notification. I don't know what caused this, but it only happened once during several weeks of testing.

Onto the specific cleaning tests. I begin by scattering a mix of oats and flour across approximately one square meter of wooden kitchen floor. I began in the quietest, least powerful vacuuming mode, with the robot driving a standard pattern and completing the route only once.

At just 60 dB, Quiet mode really is very quiet indeed, with the vacuuming itself no louder than the motors driving the robot around. As expected, this mode didn't do a particularly good job at picking up debris. It's okay for dust (or flour in this case) but struggled with the oat mix. Just like most other robotic vacuums, the Qrevo Slim's rotating side brush tends to flick debris around the room, and out of the robot's path. Telling it to perform the route twice mostly fixes this, as the flicked debris will be collected on the second pass.

Turning the vacuum power up to Balanced (one level up from Quiet) and telling the robot to clean the same area twice made a big difference. Despite only being slightly louder (about 63 dB), this setting sucked up almost all of the oat mix, with just a few pieces flicked out of reach by the side brush. Turbo mode is the next step, but at 65 dB it's only slightly louder than Balanced, but clearly has more power and was able to pick up all of the flour and almost every piece of oat.

Max vacuum strength is noticeably louder, at 69 dB. This is when the Qrevo Slim starts to really sound like a vacuum cleaner, but it's still the sort of volume you can talk over with a slightly raised voice. The cleaning power is also ramped up, providing an excellent clean.

However, on this run I noticed how when you create a zone for the robot to vacuum, it won't go right to the edges of a room, even if the zone you create overlaps the walls of the room map. This means you'll be left with a line of debris – in this case flour – swept to within a few inches of the wall but not collected. This is despite me telling the robot to clean right up to the wall. It also frequently failed to clean up directly in front of its docking station. Telling it to clean the whole room fixed this.

Finally, it's time for Max+, which even comes with a warning that it will shorten battery life due to being so power-intensive. This mode peaked at 70 dB and did a great job of collecting the debris, but the routing still meant some oats were flicked across the room and left behind; I also spotted how the robot drove over some flour without the vacuum on, then left a line of white tire tracks that it failed to pick up on subsequent passes. Requesting another clean, on a lower power setting, addressed this.

To summarize, cleaning whole rooms twice using Turbo or Max mode is best in most cases.

I then repeated these tests on carpet, and saw very similar results. The Quiet and Balanced modes are fine for a little-and-often approach, but failed to pick up all debris. Turbo and Max modes performed better, while Max+ feels like overkill for regular cleaning, but is still a nice-to-have. If I'd just moved into a new home, I'd be using the full 11,000 Pa of suction with Max+ in every room to start with, then switch to Routine or Turbo for scheduled cleaning.

Turbo mode is the best all-rounder, mixing an ability to suck flour out of a reasonably dense carpet, with a low volume level. I still wish the robot was better at collecting debris flicked around by the rotating brush, but this is only apparent when faced with very specific tests. You won't notice this during regular cleaning, but might need to occasionally pick up a few bits of debris with a handheld vacuum.

Finally, the mop. The Qrevo Slim has a pair of mops that spin at 200 rpm and push downwards for a deep clean. There are three preset water flow options (low, medium and high), plus a custom option where you can pick from a flow rate between one and 30. You can then tell the mop to clean an area once or twice, and pick from four route options, ranging from the quickest, through to Deep+, which is more thorough but takes much longer.

For my test I scattered some hot sauce across the wooden kitchen floor, left it to partially dry, then set the Roborock to work. I asked it to mop the entire room, using a moderate water flow (number 20 of 30), with two cleaning passes, and the Standard route option. In short, it did a great job. The right-hand rotating mop extends outwards, so that it can clean right up against the walls or skirting boards on an initial lap of the room, before tucking back into its default position and working together with the left-hand mop to give the entire floor a thorough wipe.

All of the hot sauce was removed, but only because I set the robot to make two passes; some stains were still visible after the first pass.

The side brush spins slowly during mopping, so it's best to use the mop on a dried stain instead of a fresh spill, as any liquid will be wiped by the brush and require manual cleaning later. It's also worth remembering that the mop uses only warm water and no detergent. (You can find premium robot vacuums that offer hot water mopping, although it's rare – the option to add detergent is more common and is included on other Roborocks, including the S8 MaxV Ultra).

The mopping process is all very quiet, ranging from 44 bB to 58 dB as the water tank is filled from the docking station, then emptied again, and the mop is cleaned using hot water and dried with warm air. The mop takes three hours to fully dry, but during that time you can ask the robot to either mop again, or do some vacuuming. The dock base (the part the robot sits on while charging) self-cleans with a pair of rotating scrapers, but can also be removed for a manual scrub. After several weeks of testing, the base still appeared as-new.

There's even a sensor in the charge station that checks how clean the robot's water is, then cleans the mops more thoroughly if required.

Lastly, the robot has a voice control system that responds to the command 'Hello Rocky'. It can be asked to 'vacuum the bedroom', 'mop the kitchen' or 'dry the mop', for example. The robot responds quickly and accurately, making voice commands a convenient way to access basic functions without finding your phone and diving into the app for more granular control.

The Qrevo Slim's battery life is a claimed 180 minutes. This feels fairly accurate, but will vary considerably depending on which settings are used.

Roborock Qrevo Slim review: app

• Easy to use, but…
• Lots of customization on offer. Almost overkill
• SmartPlan and homescreen widgets are handy one-tap solutions

The Roborock app works like most other robotic vacuum controllers. There are several customizable cleaning parameters to adjust, including five levels of suction power, three levels of water flow for the mopping function, and the option to clean an area once or twice, plus an option to pick between the standard or faster, more efficient cleaning route. Or, it can be set to only vacuum or mop a certain room or area, depending on your needs.

There's also the SmartPlan, which uses artificial intelligence to learn your cleaning habits and preferences, then creates a customized vacuuming and mopping plan.

On top of all that are the routines. If you don't want to clean the whole map, or a single room, you can instead select the After Meals routine, which can be configured to clean only the kitchen and dining room, for example. Routines appear on the home screen of the app, and can be activated with just one tap. iPhone users can create a homescreen widget with one-tap access to a couple of your most-used routines. With that set up, it's a case of unlocking your phone and tapping once on the widget to start a cleaning routine.

There are even a few pet-friendly app features, including a function where the robot will go and look for your pet without the vacuum running, using its forward-facing camera to show a live stream of what's going on.

As with other robotic vacuum apps, there are options to reconfigure your map and rename rooms. There are also masses of settings to adjust, if you wish, from cleaning schedules, to how the robot uses its lifting mops, what temperature water it uses to clean the mops, how often it empties its dust bin, and much more.

These can almost all be left to their default setting, but I strongly urge pet owners to enable pet mode in the Reactive Obstacle Avoidance page of the settings menu, since this ensures the robot recognizes and avoids pets and their waste with extra precision.

How I tested the Roborock Qrevo Slim

I set up the Qrevo Slim and used it as my only vacuum cleaner for several weeks. After using it for general vacuuming and mopping duties, I performed a series of tests to appraise its cleaning abilities, as well as its noise levels and how well Roborock's smartphone app works.

Roomba Combo Essential: two-minute review

The Roomba Combo Essential is a basic, budget robot vacuum that's designed to be effective, yet simple to use. iRobot bills it as a good choice for recent graduates, new homeowners, or anyone unfamiliar with the world of robot cleaners, while also being a worthy replacement for the Roomba 600 Series – an ultra-popular budget range that launched in 2012 and which is no longer available to buy. I put it the Combo Essential to the test, and while I've found that it can't begin to compete with the very best robot vacuums on the market, it compares pretty well to today's best cheap robovacs.

It arrives with a list price of just $274.99 / £269 / AU$499, but the current Black Friday deals mean it can be picked up for much less. Regardless, even for its listed price, the Roomba Combo feels well made and good quality, and for cleaning performance it's solid, too. The bot tackled light vacuum cleaning without issue, and when bumped up to Max suction mode it cleared both small and large debris tests pretty effectively. Even more impressive was the mopping facility – which proved more efficient than other, far pricier robovacs I've tested.

When it comes to customization options, you're limited: essentially, you can pick from three suction levels and three water levels; choose either a vacuum-only or combination vac-mop run; and opt for either a spot clean or a whole-home clean. More advanced alternatives will let you clean a room or area, and auto-adjust suction when moving from hard floor to carpet, for example. The lack of No-Go Zone option means you'll also need to manually block off any soft flooring areas when running a combination vac-mop run, or you better believe it will attempt to mop those carpets for you.

Mapping, too, is basic – I'd politely describe the general behavior as "erratic". You're also limited in what you can achieve remotely. You can pause or resume cleaning; but the app doesn't offer a return to dock option, for example, in the even the bot ends up doing something that it shouldn't during a cleaning run – and based on my experience, this could happen. This does mean that it's probably best to avoid setting the Roomba Combo off on a clean unsupervised, which is a little annoying since most folk are likely to prefer to have their robovac complete duties while they're out of the house, for minimal disruption.

Note, too, that there's no option to add an auto-empty dock, which will result in an irritating amount of manual emptying if you have pets or a large, high-traffic household. However, for small homes, emptying is perfectly manageable and the tiny, charge-only dock is actually a benefit. (Note: the newer, similar Roomba Combo 2 Essential does have an auto-empty dock).

Despite having had a somewhat frustrating time testing this spirited little robovac, I'd still actually recommend it to some people. If you have a small home and just want to do whole-home cleans once or twice a week, the Roomba Combo will perform just fine. The small dock won't get in your way, and if you're happy to manually empty it every couple of weeks, then it could be a major time- and effort-saver for very little outlay. That's the short version; read on for my full Roomba Combo Essential review.

Roomba Combo Essential review: price & availability

• List price: $274.99 / £269 / AU$499
• Launch date: April 2024
• Available: US / UK

The Roomba Combo Essential robot is widely available around the world. It comes with a list price of $274.99 in the US, £269 in the UK and AU$499 in Australia, but I've already seen it discounted heavily – at time of writing, the Black Friday robot vacuum sales are in full swing, bringing the price down closer to $150 / £150.

Even at the list price it's in the budget bracket, and performance is roughly what I'd expect at that price. You don't get the extensive features and hands-off dock functionality of pricier bots, but build quality is good, and there are some thoughtful design features. As a basic model it offers decent value for money, especially if you can snag a discount.

Roomba Combo Essential review: design

• Combination vacuum and mop with a low-profile design
• Basic charge dock; no self-empty features
• Single bristle roller rather than iRobot's usual dual rubber rollers

The Combo Essential is a combination model, which it offers vacuuming and mopping capabilities. Many (pricier) robovacs have a raised central puck to house a camera; because the Combo Essential comes without, it has a relatively shallow profile, enabling it to clean under low furniture without issue.

There are three physical buttons on the bot itself: a Clean button (with power icon) to start, pause and resume cleaning tasks; a Home button to send the Roomba Combo back to its dock; and a Spot Clean button for tackling small, targeted mess. On other robovacs I've tested, these have been superfluous; but on the Roomba Combo Essential, I did find myself having to use them fairly regularly (more on that in the Performance section).

Flip the bot over, and you'll find a V-shaped bristle brush. It's described as "multi-surface", so presumably built for use on both hard floors and carpet. This is the only Roomba to not feature iRobot's patented dual rubber rollers. These rubbery rollers are excellent at pulling hair and debris from carpets, so I was interested to see how this alternative design compared. There's the usual triple-pronged edge brush, designed for tackling dirt at the edges of rooms.

Annoyingly, iRobot refuses to release its suction stats, arguing that other design elements also play a part in the overall effectiveness of a robovac's dirt pick-up. While that is true, a figure in Pa does provide an easy point of comparison when sussing out your various options.

What I do know the Roomba Combo offers the same "standard" cleaning offered by the majority of other Roombas (bar those right at the top of the range), and that it has 18x more suction power than the Roomba 600, which perhaps isn't surprising given that series launched in 2012. You can select from three different suction levels in the app.

Housed at the back of the robot is a removable section that includes both the dust cup with filter and the water reservoir. This is very well designed, with a brush/slicer tool clipped in, for clearing any stuck debris from the bin, and removing tangled hair from the brushroll. The inlet for the water reservoir is found beneath the rubber stopper bearing a water droplet icon.

The mop is a D-shaped microfiber pad. These are pretty common (even on far pricier models), although I tend to find dual, spinning mop pads do a better job of scrubbing. Some budget models simply drag a wet wipe across the floor, so the Roomba Combo's offering is at least a big step up from that approach. In fact, I was pretty impressed with this model's mopping capabilities, but I'll get into that in more detail below.

The mop pad is fed from the small onboard water tank, and there are three water level options, which you set manually. This robot can vacuum and mop simultaneously, thus taking care of your hard floor cleaning in a single pass, although I probably wouldn't recommend doing this.

Some more affordable Roombas, such as the Combo j5, require you to manually swap over the whole back plate when you want to change from vacuuming to mopping. Here, the tank stays in place; but if you want to send the bot on a vacuum-only run (or avoid damp carpets), you'll need to remove the mop pad. It clips on easily, on top of where the bin and water tank sit.

The dock is a minimalist unit that simply charges the bot. In fact, it's teeny-tiny compared to other robovacs I've come across. Most pricier Roombas have the option of adding a more advanced base (sold as "Plus / +" versions) – the simplest of these just empties the bot's small dust cup into a larger one in the dock, while the most advanced options can also refill the water tank and wash/dry the mop pads.

There are no alternative dock options here, so you'll have to take care of all that maintenance manually. For people like me who have a small home, that's a worthwhile compromise not to have a bulky dock cluttering up the space. However, if you have a large home with lots of people traffic, or pets, it's probably worth choosing an option that can be used with a self-empty dock, to save you the hassle of constant manual emptying.

One minor complaint is that I found the cable a little short (41in / 105cm long). That, together with the requirement that the dock sit on a hard floor and have half a meter of clear space either side and 1.2 meters in front (this is pretty normal for a robovac dock) meant I had to get an extension lead out. There is a cable tidy at the back of the dock to prevent the bot becoming tangled in any spare cable on its travels.

Setup was straightforward, simply involving removal from the packaging, snapping on the side brush and mop pad, plugging in the dock and charging. There are clear instructions in a booklet, plus a QR code to download the app, and a further one to link the bot to your app. This app then walks you through the final stages of getting ready to clean, before (in my case) launching a software update.

Since the Combo Essential works on a 2.4GHz network, the official advice is that you'll need to make sure both the bot and your phone are also on 2.4GHz Wi-Fi during setup. After that, you can switch back to 5GHz, if you have it. However, I thought I'd try setting up my bot without changing the settings on my Wi-Fi and it managed just fine.

This is a more basic model, so don't expect a long list of smart features. It's powered by iRobot OS, promises up to two hours of cleaning on a single charge. It can be controlled via the iRobot Home app or with your voice, provided you have an Alexa-, Siri-, or Google Assistant-enabled device.

Roomba Combo Essential review: performance

• Decent vacuuming, surprisingly good mopping
• Erratic behavior
• Requires more manual involvement than most

Having set up and charged the Roomba Combo Essential, I set it off on a whole-home vacuum of my one-bedroom flat. This did not go very smoothly. On the first run, the bot bumped its way around a bit before finally becoming stuck in a cycle cleaning back and forth in front of my fireplace (there were zero obstacles preventing it from leaving the area).

After around 25 minutes or so completing this same short route, I decided to send it back to dock to try again. There was no option to send it back to the dock via the app, so I had to press the button on the machine itself. On its way to the dock, it took a detour into my bathroom for the first time, and simply stopped there – again, for no apparent reason. A second attempt at a full-flat clean yielded slightly better results, but still far from perfect.

After the initial mapping process was as complete as I could hope for, I started with our standard vacuuming tests: a sprinkling of oats and (separately) blitzed up biscuit crumbs, sprinkled on the floor, to see how the robotic would cope with fine and chunky debris.

I started on carpet, using the Spot Clean function and the medium vacuuming setting. The Roomba Combo Essential flicked around a fair bit of debris, but sucked up most of the spillage on the first go. I then bumped up the settings to maximum suction, and ran the test again, after which there were only a few remnants remaining.

On hard floors the bot's performance was a little better. Still a fair bit of flicking mess around, but medium mode was enough to pull up most of the debris on the first pass.

In fact, the issue on hard floor wasn't so much with suction but navigation. On carpet, the Roomba Combo made its way out from where I had placed it in a neat outward spiral shape, thus gathering most of the debris on its travels. However, on my lino floor, for seemingly no reason, it decided to adopt an arc-based route. As a result, it was tricky to get it to even pass over the debris.

Since there's no auto-empty, you'll need to manually empty the onboard dustbin. This mechanism is straightforward, and feels well designed, with chunky clips to detach the bin. If you're cleaning a relatively small home (and don't have pets), this isn't too much hassle.

When you want to mop, you'll need to attach the mop plate onto the bot. This is simply a case of clicking it into place. iRobot suggests dampening the mop pad before attaching it, for best mopping results. You'll also need to fill up the onboard water tank before you launch any "combo" job. If you try to launch a vacuum-only task, it will helpfully inform you that the mop pad is attached.

iRobot suggests removing rugs before launching a combo run, and you'll also need to physically block off any areas where you don't want the bot to venture with its mop. I don't have a door between my (lino) kitchen and (carpeted) lounge, so I had to create a physical barrier before each combo run.

I had low expectations for the Roomba Combo Essential's mopping skills, but I was pleasantly surprised. Again, navigation was erratic, but I could see from the damp stripes on my floor that it was doing an efficient job – in fact, better than some far pricier robot vacuums I've tested.

My only real complaint was that it really tried hard to escape into my carpeted lounge – if you don't have doors you can close, you'll need to be prepared to put some sturdy barriers in place.

I also tested to see how well the Roomba Combo Essential coped with sticky mess (tomato ketchup) and liquid mess (apple juice). It sucked up the juice with no issues, and smeared the ketchup about a bit; but ultimately, after a couple of passes, the robot vacuum had cleared it.

Having said that, I wouldn't actually recommend using a robovac on spillages such as ketchup, because the condiment will get on the wheels and track around the house. Here, it ended up on the tracker wheel, which isn't removable and thus proved a pain to clean.

This robovac vacuums and mops at the same time, but I'd actually recommend running over surfaces in vacuum-only mode first. I did my combo run while there were still remnants of the vacuuming test on the floor, and it ended up in a disgusting gunk in the dust bin.

In general, it's worth stating that no robot vacuum will do as good a job of mopping as a manual mop option. They're really just for light cleaning, and for this, I found the Roomba Combo Essential more than adequate.

After each combo run, you're advised to empty the water tank of any unused water, while also rinsing the mop pad and leaving it to dry. Since there's no spare pad included, you'll need to make sure you have time to do this (spares are available to buy via iRobot, alongside other replacement parts). It's machine-washable for occasional deeper cleaning.

• Performance score: 3.5 out of 5

Roomba Combo Essential review: app

• Well designed, but limited options
• Can't do some basic things remotely
• Compatible with popular voice assistants

iRobot's companion app is well designed and intuitive. It offers only basic customization / control options: essentially, you can choose from three vacuum and three mopping modes, and you can choose to vacuum-only or combo vac-and-mop. Pricier models offer far more control over what they clean and how they do it.

After a task is complete, the app will provide a time summary of recently completed tasks and an outline of its journey. You'll need to figure out where the bot has and hasn't been from just a shape – there's no labelling of rooms here. That's expected at this price point, but I do struggle to understand why iRobot has opted an almost impossible to see yellow/green color for said maps.

There are limits to what you can achieve remotely. You can start and pause cleaning, but there's no return to dock button. As such, if you need to cut a job short for whatever reason, you'll need to find the bot and press the button on top. For spot cleans, you'll need to manually pick up the bot and take it to the bit that needs cleaning, then press the Spot Clean button.

You can't instruct the bot to clean just one room, and because no-go zones aren't an option, if you want to stop it from going somewhere, you'll need to physically restrain in (using doors).

There is a Clean While I’m Away automation option, where the bot will automatically start cleaning when you leave the house – although, personally, I wouldn't leave this bot to clean unsupervised. Finally, the app offers suggested schedules based on previous jobs.

Roomba Combo Essential review: alternatives

Within the "cheap Roomba" remit, there are a few options. If you want to see what you could get if you shelled out a little more, my Roomba range guide should help.

Roomba Vac Essential

In some countries, including North America, there's a vacuum-only model called the Roomba Vac Essential. This is very similar to the Combo Essential, but without any of the mopping capabilities. However, it isn't available direct from iRobot and can be hard to find elsewhere now, too.

Combo 2 Essential

In October 2024, iRobot added the Roomba Combo 2 Essential robot + AutoEmpty dock. The big difference compared to the original Essential is that it has an auto-empty dock, which will be a big benefit for those dealing with high levels of dirt or hair. It also apparently has "2x the cleaning power of the original Essential series". No specifics are given on this, but note that it's not "twice the suction power", so I'm thinking probably design tweaks. It also has an improved bumper design, and the ability to recharge and resume during cleaning missions. In short, a better choice for bigger homes and higher dirt levels.

Should you buy the iRobot Roomba Combo Essential?

How I tested the Romba Combo Essential

• I used it for a week as my regular vacuum
• I ran specific vacuuming and mopping tests
• I tested the app and any special features

For this Roomba Combo Essential review, I used this model as my main vacuum for a week. I ran the standard TechRadar suction and mopping tests, seeing how well it coped with fine debris (cookie crumbs), larger debris (oats), wet spillages (juice) and sticky spillages (dried tomato ketchup). I also noted how well it coped with my collarbone-length hair on its travels. I tested the spot clean function, mapping, and general usability.
