Eufy E15 robot lawn mower: two-minute review

To date I've tested quite a few wire-free, autonomous lawn mowers, but of all of them, the Eufy E15 is the easiest to set up and use. Much of that is down to the robot's AI algorithm-rich software, its superb dual camera system and the simplicity and excellent navigability of the Eufy app.

This admittedly odd-looking lawnbot uses Full Self Driving (FSD) technology, which means there's no need to lay a perimeter wire or install an RTK GPS antennae. In fact, setup took all of about 15 minutes – it can automatically map a lawn up to 800 square metres by cleverly distinguishing the textural differences between grass and planted borders. It then goes out and cuts the lawn in pristine parallel stripes before finishing off with an edge cut along the borders.

Like many robot mowers, the E15 is equipped with a small 20cm cutting deck comprising three razor-like blades attached to a spinning disk. These blades are so sharp that they snip grass with the cleanliness of a pair of scissors, leaving the tips of the nitrogen-rich cuttings to fall back to earth, which in turn fertilise the lawn.

There are a few minor niggles – the navigation system means it can't mow at night, and it can't handle gradients over 18-degrees – but overall, this is an extremely impressive lawnbot and a very strong recommendation for technophobes in particular. Aside from an easily-fixed map-making mistake, and one expected issue regarding small obstacle avoidance, the E15 hasn't put a foot wrong during several weeks of testing. It just works out of the box. That's the short version; read on for my full Eufy E15 review.

Eufy E15 review: price & availability

• List price: $1,799.99 / £1,499
• Available: US / UK
• Launched: June 2025

Eufy's first robot mower is available in two variants – the E15 I'm reviewing here, and the E18, which is only available in the US. Both machines are the same size and spec but the E18 has a larger capacity battery which allows it to cut lawns up to 1,200m² / 0.3 acre – that's 400m² more than the E15.

If you live in the UK, you can purchase the E15 direct from Eufy UK for £1,499. Granted, it's an awful lot of money but that's the price one pays for new tech that saves a ton of time and effort. I personally think it's very competitively priced, especially given the fact it comes with a roofed garage to protect it from the elements. It's also exceedingly well built, using highly-quality materials with expert fit and finish.

Stateside dwellers, meanwhile, have a choice of either the E15 or E18. The US Eufy site lists the E15 at $1,799.99 but if you have a lawn larger than 800 square metres (0.2 acre), I would suggest the E18. Eufy sells this model for $1,999.99.

Eufy E15 robot lawn mower review: design

• Full self driving lawnbot, uses cameras to navigate
• Comes with a charge dock but requires no boundary wires or RTK receiver
• Otherwise relatively standard lawnbot design, with 20cm cutting deck

Eufy (a subsidiary of Chinese electronics manufacturer Anker) has approached the development of its first robot mower with the same set of design principals it has applied to its burgeoning range of excellent robot vacuum cleaners. Hence, the E15 is probably the most robot vacuum-like lawnbot on the market right now. And that's a very good thing for anyone who already owns a robot vacuum cleaner and is familiar with the way it is set up and used from day to day.

Although it's not the prettiest looker on the lawn (at least when compared to the F1-inspired Mammotion LUBA Mini), the E15 feels very high quality. It is also the only robot mower I know of to come with a roof for its charging dock as standard – that can be considered a major benefit because, while the E15 is IPX6 rated for waterproofness (IPX6 means ingress protection against powerful water jets), it's direct summer sunshine rather than rain that could have the biggest affect on batteries and electronics.

Incidentally, like all modern robot mowers, this model is fitted with a rain sensor so if it starts raining while it's out cutting, it will return to base and wait a predetermined number of hours before it heads out again.

Although size and weight is pretty inconsequential given that, once in situ, the E15 pretty much stays on the lawn until the end of the cutting season around late autumn, for the record the E15 measures 23.7 x 15.5 x 12.5 in / 60.3 × 39.4 × 31.8cm, weighs 39.7 lbs / 11kg and comes with an integral handle on the front so it's easy enough to lift if necessary.

Like all robot lawn mowers, the Eufy E15 is equipped with a cluster of manual control buttons on the top of its outer casing, including a large red Stop button for any unlikely emergencies. These buttons are handy for quickly pausing or cancelling a task, commanding the robot to return to its dock and turning it on and off without the need for the accompanying app. There is also a master on/off switch on the base of the cutting deck, which is only used when putting the robot into storage or transporting it in the car.

Before we tackle the E15's clever navigation system, let's head below and take a closer look at the business end. This model is good for lawns up to 800m² (0.2 acres) and has an 8in / 20.3cm cutting width – that's the norm for a robot of this size, but still way short of the Mammotion LUBA 2 which has a generous 15.7in / 40cm deck.

Like almost all current robot mowers, the E15 uses an array of small razor-like blades for the cutting process. Put simply, a silent motor spins a circular disc with, in this case, three double-sided 1.5-inch razor blades attached to the disk's outer edge.

Since the blades are attached loosely and are able to spin 360 degrees, the disk's centrifugal force causes the blades to whip round at immense speed so the grass is cut to a much finer degree than any large-bladed rotary mower. Likewise, if they hit something hard like a stone, the easily replaced blades are less likely to be damaged. (Here's more on how robot lawn mowers work, if you're interested.)

Aside from the whisper-quiet sound the cutting system makes (and believe me this thing is near-silent in operation), the main bonus of a system like this is that the fine nitrogen-rich cuttings the robot leaves in its wake are fed back into the lawn as future fertiliser. This 'mulching' method of grass maintenance is not only good for your lawn, but it also means you don't need to figure out what to do with all the cuttings.

The Eufy E15 is rear-wheel drive and those wheels are an ample 7.9 in / 20cm in diameter, with deep treaded paddles that provide excellent traction without causing any grass damage. The front end is fitted with a robust castor wheel that allows the robot to turn on a sixpence. Eufy states a maximum gradient of 40% (18 degrees) which is a few degrees steeper than much of the competition but still nowhere near the Everest-scaling, all-wheel-drive Mammotion LUBA 2 and LUBA Mini's 80% (38.6 degrees) ability.

Robot mower navigation tech has come on in leaps and bounds since the first models were introduced way back in the mid '90s. These early models required a boundary wire around the perimeter of the lawn and many robot mowers like this are still available to purchase today. However, recent advances in RTK GPS, LiDAR and camera-based navigation technologies are quickly making these types of wired robot mowers obsolete.

Take this model, for instance. The Eufy E15 is equipped with a FSD (Full Self Driving) camera tech that works in a similar way to many autonomous cars. The system itself is comprised of two side-by side cameras that produce a stereoscopic image with some depth to it, rather like a pair of human eyes. This, along with a smorgasbord of AI algorithms and heaven knows what else it has hidden beneath the bonnet, ensures that the robot can not only find its way around a lawn but also differentiate between grass and border plants.

Like a human, it can spot the textural and height differences between grass and plants and map the lawn accordingly. And for those who love driving RC cars, you can easily do that with this mower, too, and even view a high-definition livestream of what the camera sees.

The downside to a camera-based system like this is that the E15 cannot mow beyond sunset because it won't be able to see where it's going. Eufy might elect to fit a bright headlamp on the next incarnation but for now, your best bet for night mowing is either the Mammotion LUBA 2 or its new smaller sibling, the LUBA Mini.

The upshot of this robot mower's superb navigation system is that it gives it the amazing ability to cut a lawn in a series of perfectly straight parallel stripes that never fail to impress. Granted, they're not bona fide stripes like a cricket ground, but they're the next best thing. I guarantee you'll be blown away by how smart your lawn looks after just one cut.

Finally, a shout out to the E15's security measures. Firstly, it's bonded to the user's account and Wi-Fi system making it useless to any light-fingered thieves. But as an extra precaution it also features GPS tracking over optional 4G while the unit itself will sound an alarm, enter a locked state and send a notification to the user if it's ever taken beyond its working boundary.

Eufy E15 robot lawn mower review: setup

• Charge dock requires power source and good Wi-Fi signal
• - Mapping is fully automated – and no-go zones can be added in-app if required
• - Extremely fast and east to set up

No question, the Eufy E15 is one of the easiest robot mowers I've ever set up; there is no RTK GPS antennae to install and not a perimeter wire in sight. All you need is an electricity source within the eight metres of cable provided and a decent WiFi signal to the robot so you can initiate its setup procedure, update the firmware when required and program weekly schedules and other parameters in the Eufy app.

Once you've created a Eufy account in the app and mounted the charging dock using the provided ground screws, it's simply a case of firing it up and selecting the auto map function. I'd say the whole process took me about 15 minutes and most of the time was spent screwing in the dock's ground screws using the provided Allen key (a cordless driver with an Allen key bit speeds this process up considerably). The E15's excellent mapping ability is fully automatic – the bot can tell the difference between grass and plants, and uses this information to map the lawn.

However, there may be instances when it treats a scrubby patch on the edge of the lawn as grass and map that too – as was the case in my testing. With some robot mowers you need to physically steer the robot like an RC car to the area in question and modify it by driving the bot on a different trajectory and then saving the map. With this model you simply add a no-go zone or a virtual boundary by drawing a square or line on the app's map. A big high-five to the designers for bringing this robot vac-style editing approach to the table.

While this whole process was very simple, I still hope Eufy will include a manual mapping option in a future update for those who want full hands-on control. Manual mapping – where you drive the robot around the perimeters of a lawn like an RC car – allows the user to fine-tune the map right from the off, with no need to add no-go zones or virtual boundaries.

Once the mapping has finished, it's time for the robot's first mow. But before you do this, make sure your grass isn't too long or the cuttings it creates could litter the lawn. Instead either opt for the highest cutting height first (these range from 25mm to 75mm in 5mm increments and are set using the app).

Alternatively, use your standard mower with grass catcher to cut the lawn to about 40mm (position 4) and set the robot off on its first cut a day later – I find that 35mm is a perfect height for UK rye grass. Once the grass is ready for the robot, chances are you may never need to use your standard mower again, though you will still need your line trimmer to tidy up some edges every now and then.

If you have a few different lawns separated by pathways and boundaries, that's not a problem. The Eufy E15 can be programmed to cut all of them in succession, even when they're many meters apart. Simply map the lawns individually and set a virtual passageway between them by steering the robot from one lawn to the next. The robot will then follow this set path from lawn A to lawn B and so on and so forth every time it's on a cutting session. Just make sure that there are no gates or stairs in the way and that the passage the robot takes is free of clutter and wide enough for the robot to navigate.

Eufy E15 robot lawn mower review: performance

• Neat, methodical cutting performance
• Motorized cutting heights
• Expert navigation and very good obstacle avoidance

In terms of cutting performance, I've been exceedingly impressed by how well this robot mower has navigated and cut my lawn, and in such methodical fashion too. It's a joy to watch the E15 as it trundles up and down the lawn in perfect parallel lines, and I love the pseudo stripes the wheels leave in their wake.

The fact you can easily adjust cutting parameters in the app – cutting height (from 25mm to 75mm), edge spacing (how close it cuts to the edge), path spacing (the amount of overlap between each pass), and travel and blade speed (slow, standard and fast) – is the icing on the cake. And if you're looking for the cherry on top of that, it'll be the Path Direction (cutting angle) setting, which is as simple as placing two fingers on the map of your lawn and swiveling the two arrows to the angle of cut you want, whether it's perfectly vertical, horizontal or any angle in between.

Despite this model only having three cutting blades against the Mammotion LUBA Mini's six, I haven't been able to detect any noticeable differences in cut quality. Yes, I prefer the wider tract of the big 40cm Mammotion LUBA 2 – the width of a small push mower – but I'm nitpicking here.

Obstacle avoidance on indoor robot vacuum cleaners is essentially for the convenience of not having to untangle a loose sock from under the robot, but a robot mower with fast spinning razor blades is an altogether different kettle of danger. Just as well that all autonomous robots and most wired models have various levels of obstacle avoidance built into their navigation systems.

The Eufy E15's obstacle avoidance is excellent for anything larger than about the size of a tennis ball. I tested it on a number of occasions using some dog toys. Amazingly, the E15 avoided every item including – surprisingly – a small whale-shaped toy with a slim tail. In fact I was especially impressed by how well it managed this last feat because the whale was off-centre to the robot, and yet its camera caught the obstacle in its periphery.

However, as expected, the E15 didn't spot a table tennis ball on two occasions and rode over it, almost slicing it in half. As a result, I wouldn't trust this model to avoid pet mess unless, perhaps, you have a Great Dane, or a horse. (This has been the case with every robot mower I've tested, and for that matter every robot vac, too.)

I'm pleased to report that everything has run smoothly with this model, from its initial auto mapping to its weekly routine of keeping the lawn looking spick and span. It has never got lost or failed to find its charging base, and it's always remained within the confines of its boundary. And that's not a bad accolade for any manufacturer hitting the market with a first-time product. Well done Eufy.

Eufy E15 robot lawn mower review: app

• Easy to navigate
• Excellent interface
• Could do with a couple of extra features

While I'm a huge fan of the Mammotion range of robot mowers, its accompanying app is quite technical and, in some areas, difficult to get a handle on. By contrast, the Eufy app (which also covers Eufy's security cameras) is mostly a joy to use, and mercifully free of any technical jargon. It's as simple as simple can be, but there is room for improvement.

What I'd like to see is an option to manually map a lawn and an option to mow in a chessboard pattern (i.e. cut vertically and horizontally) in one go. But I'm pretty certain we'll see something like this in a future update. It is, after all, early days for this newcomer.

How I tested the Eufy E15 robot lawn mower

I've been using this lawnbot for the past few weeks, and I've been working it hard during that time. It has been out on regularly scheduled mowing tasks, and I've also put it through a range of tests – including assessing its obstacle avoidance using dog toys. I also assessed the ease of setup, how user-friendly the app is, and how the cutting performance compared to other lawnbots I've reviewed.

Hobot S7 Pro: two-minute review

The Hobot S7 Pro is a square robot that clings to your window and cleans dirt away using dual cleaning pads and a fine spray mist. It can be used indoors and out, and is suitable for framed or frameless windows. The large size is well suited to big windows; note that if the pane is too narrow, it won't clean it at all.

On test, I found this bot did a great job of cleaning lightly dirty glass. It's easy to use, navigates accurately, and doesn't miss any spots. However, it struggles with tougher dirt, which is probably true of most window bots. When I used it on the outer panes of my large patio doors, with some water marks and general grime accumulated from being exposed to the elements, the results were a little streaky. In contrast, my indoor glass partitions were left perfectly clean with no smears at all (and the bot accurately detected the frameless edges, which impressed).

The design of the S7 Pro is largely effective, with a few downsides. At time of testing, app support wasn't available, which meant I had to rely on the remote control. This requires you to point the remote directly at the robot, which is sometimes awkward. I also found the voice prompts shrill and irritating – and there's no way to switch them off. During my extensive testing period, the bot did once fall off a window.

Price-wise, the S7 Pro is an investment, but roughly in line with the wider market. You won't be saving much time by opting for this bot and, unlike a robot vacuum, you can't leave it to do its thing unattended – you need to be around to move it from pane to pane. However, in a home with lots of glass, or glass that needs regular cleaning, it could be a big effort-saver, and worth the investment. That's the short version; read on for my full Hobot S7 Pro review.

Hobot S7 Pro review: price & availability

• List price: $439 / £329
• Available: US / UK
• Launched: 2025

The Hobot S7 Pro is available in the US and the UK, with a list price of $439 / £329. Solenco – the brand behind Hobot – also has a presence in Australia, but at time of writing, the S7 Pro wasn't available there. You can buy it direct from Solenco in the UK, and via Amazon in the US, although I suspect it will become more widely available as time goes on.

The S7 replaces the S6 in the Hobot range. Unfortunately, I can't find the pricing for that model anywhere, and nor can I discern the exact differences between the S6 and S7 models. (I've requested the information and will update this review when I hear back.)

A major competitor in this market is Ecovacs with its Winbot line. Models range from around $230-$700 in the US or £300-£500 in the UK. In general, though, the models closest to the S7 seem to be roughly the same price.

The Hobot S7 Pro isn't an especially cheap alternative to manual window cleaning, but it could be worth the investment if you have a lot of glass to clean, or if your windows get dirty quickly.

Hobot S7 Pro specs

Hobot S7 Pro review: design

• Square-shaped bot with dual reciprocating cleaning pads
• Sprays fine mist from two small water tanks
• Controlled via remote control – app support advertised, but unavailable

The Hobot S7 Pro is a square robot with dual reciprocating cleaning pads. It clings to your window and makes its way across its surface to clean it, with the aid of "AI-powered navigation". This bot is suitable for both framed and frameless windows, as well as patio doors and mirrors. While the following isn't addressed in the literature anywhere, previous reviews suggest the S7 Pro is only suitable for perfectly vertical surfaces.

Size-wise, the bot is rather large, so better suited to big windows (in fact, it refused to clean a 12.6in / 32cm wide window, I think due to lack of maneuvering room). The brand makes a range of smaller window bots, shaped like elongated ovals, which might be a better option if your windows aren't sizeable.

On the upper side of the unit is a grip handle for attaching and removing the bot to a surface, plus an on/off rocker power switch and a start/pause press button. On either side are two small, 80ml water tanks, sealed with a rubbery stopper. These can be filled with water and/or Hobot's own (supplied) cleaning solution; they're detachable with the aid of a screwdriver. Attached to each one is an "Ultrasonic nozzle", which sprays a very fine mist into the path of the bot as it moves around the surface. These are apparently extremely sensitive and not to be touched under any circumstances.

Flip the robot over and you'll find two rubbery caterpillar belts and two removable, washable cleaning cloths. These have rectangular sections cut out of the middle, to leave the suction area the bot uses to cling to the glass free. The cloths are mounted on separate plates, and vibrate vertically in towards each other. Hobot says this simulates the motion of a human hand scrubbing, although with up to 600 "wipes" per minute, it's rather more frenetic than any window cleaner I've met.

On the edges are bumpers to protect your window frames. This model also includes patented Edge-Leakage-Bumper (ELB) sensors, which are designed to make this cleaner suitable for edgeless glass. These sense if there's a loss of suction as a result of a gap, or if the bot reaching the edge of a pane of glass, and change direction rather than continue over it, breaking the main suction seal and dropping off.

The device needs to be plugged into the mains to work. Thankfully, the cable is nice and long, but you might still need to make use of an extension cord for awkwardly placed outside windows. You'll also need to keep the backup battery charged, in case of a power outage – this will keep the bot attached to your window for up to around 20 minutes without power.

A safety cable is provided as a further backup if you're cleaning windows up high. I was pretty lax about attaching this until the bot fell off one of my windows. This only happened once during my extensive testing period, and luckily I was close enough to catch the rope before it hit the ground outside, but I learned a lesson about being diligent with attaching the rope.

Control is via remote. This offers a few different cleaning cycles – with the one you'll probably want to use helpfully colored in blue – plus options to turn the spray on and off, or manually direct the cleaning path if required. Unfortunately, you need to be pointing the remote directly at the bot for it to register, which can sometimes be tricky to achieve. Ideally, I'd have used the companion app; app support is advertised for this model, but didn't appear to be available at time of writing.

The bot will also provide information by yelling at you in a rather shrill voice, accompanied by various loud beeps. It needs to be loud to be heard over the suction of the machine, but that doesn't make it any less irritating, especially given it repeats the same safety instructions every time you turn it on.

• Design score: 4 out of 5

Hobot S7 Pro review: performance

• Navigates accurately and doesn't miss any spots
• Excellent for maintenance cleans, but can smear dirtier windows
• Not especially speedy, but does save on effort

The Hobot S7 Pro's dual pads vibrate in a reciprocating (linear, side-to-side) motion to clean and buff your windows. The water tanks apply a fine mist onto the surface of the glass, but this is by no means a wet cleaning setup – after cleaning three large floor-to-ceiling windows, the pads were only very slightly damp around the edges.

It's easy to get started, although if you're unfamiliar with window-cleaning robots, you might need to watch a video or two to understand how it will work. You need to hold the bot against the window and switch it on manually – at this point the suction will kick in, along with a loud voice prompt, and you can let go.

Then you can start the cleaning run. Unlike, say, a robot vacuum, there's no need to map anything first: just set off your preferred cycle and the bot will do the rest. I found the S7 Pro navigated my windows accurately, turning after it had bounced lightly against the window frame or sensed a gap in the glass. Route planning is apparently aided by AI, although each of the buttons on the remote launches a specific cleaning pattern, so I'm not exactly sure where the AI comes in.

The water tanks spray jets of mist – from the side the bot is moving towards – at regular intervals (it isn't "continuous", as some of the literature on the bot states). Filling the tanks to max gave me enough liquid to clean one side of one pane on my patio door, plus a bit more; but you'll still have to top these up quite regularly.

The cleaning coverage is excellent: the S7 Pro left only a small margin around the edges of my framed windows. Previous Hobot window-bots have used two circular cleaning pads; the squared-off design here seems much better suited to regularly proportioned windows.

The ELB (Edge-Leakage-Bumper) sensors are designed to make this bot suitable for edgeless glass (explained more in the Design section). I tested it on some indoor glass partitions that have a 1.5in / 4cm gap at the sides, and the feature worked exactly as advertised – the bot stopped short of the wall and changed direction.

In terms of cleaning results, I'd give it a middling score. For lighter, maintenance cleans, it performed very well. Using it on relatively clean windows indoors, the results were excellent, with no smearing.

However, when faced with the dirtier outside panes of my patio doors, the S7 Pro struggled. While windows were left significantly cleaner than they had been, the results were streaky. I could see the path the bot had travelled, and the occasional caterpillar track-mark. Don't expect the bot to be able to clean off caked-on dirt or bird poo, either.

Overall, I'm not sure that the ultra-fine mist is sufficient to tackle tougher dirt; I think a little more liquid would help. In addition, when using the S7 Pro outside, I could see that much of the mist was getting blown away in the breeze rather than landing on the window.

On dirtier windows, Hobot suggests you run a no-spray cycle first, to buff off surface dirt. I also found a brand video that recommended drizzling a little bit of cleaner solution on clean pads before starting, to help with grip. I found both of these tips improved the results on dirtier windows.

As as side note, the S7 Pro was also an unexpected win for cleaning behind the safety railings on some second floor, floor-to-ceiling windows; an area that's extremely awkward to clean any other way.

Generally, the bot adhered well to my window, and felt securely attached when giving it a little tug after pausing operations. However, it did once fall off a window, seemingly for no reason.

In terms of timings, Hobot advertises that it will clean an area of 1 square meter in 2 minutes 36 seconds. In practice, a complete, standard cleaning run takes rather longer than that – in my tests, it cleaned a 1.3 square meter pane of glass in around 7 minutes 30 seconds. So you're not saving a ton of time by opting for this method of cleaning, but you are saving on effort.

In general, like most robotic home assistants, the Hobot S7 Pro doesn't do as good a job as a human would do with a manual tool. It's designed for maintenance cleans that can be supplemented by the occasional proper window-wash, rather than to replace humans entirely. Also note that you can't leave it to clean unattended – you'll need to be present to move it from pane to pane.

How I tested the Hobot S7 Pro

I used the Hobot S7 Pro window cleaning robot to tackle various floor-to-ceiling windows, both inside and out. I tested its different cleaning modes, as well as the remote control option. I focused on how clean it left windows, if it missed any spots, and if it could achieve the advertised streak-free finish. I also assessed how easy it was to use, its noise level in operation, and if there were any design features that proved troublesome.
