A lot of robot for less than £1000, the Eufy C15 Robot Lawn Mower is simple to set up: plug the docking station in, connect the robot to Wi-Fi and off you go. It's camera-based navigation works brilliantly in smaller gardens, and the cut is excellent. It's a bit disappointing that 4G costs extra, and this lawn mower isn't very good for bumpy ground or steep slopes, but for smaller, simpler gardens it is excellent.
- Very simple to set up
- Maps quickly
- Excellent cut
- Not so good on bumpy ground
- 4G costs extra
-
Adjustable cut height Manual dial gives you adjustment between 20mm and 60mm
-
Camera-based vision No complicated RTK, the cameras help the robot locate itself
Promising to keep things as simple as possible, Eufy’s C15 robot lawnmower doesn’t need GPS, LiDAR or boundary wires to map your lawn or keep it looking trim, using AI-powered cameras to find its way around.
It’s great, but only if you have a flat garden. The effortless setup process is a huge win, but it misses features like automatic height adjustment, and it’s a shame that it puts some functionality behind a paywall.
Design and Features
- No RTK station to set up
- Handy roof on the charging dock
- 4G module costs extra
A small and nimble little robot lawnmower, the C15 weighs just under 11kg. Powered by a pair of big spiky wheels on the back, it relies on these for steering as well. The hidden front wheels are smooth shopping trolley-style ones. It means this robot is only really useful on flat ground. It can tackle slopes up to 18° but is much more suited to flat lawns.
Eufy’s C15 robot mower is immediately impressive because it doesn’t need a clunky RTK station. It lives in a neat charging dock with a roof. That should help to keep this bright white robot a bit cleaner between cuts.
Something I don’t like about white robot lawnmowers is that they show up dust and dirt quickly. Within a couple of days, the C15 looked like it needed a clean. It’s not terrible, but a black or grey robot hides the dirt better.
There are only a few buttons on the robot itself. A big red emergency stop and basic soft touch function buttons can send it out or back to the dock to charge, even if you don’t have your phone on you.
To find its way around the garden, it uses AI-enhanced cameras rather than an RTK station, just like the previous model did, the Eufy Lawnbot E15. The cameras look out for the edge of the lawn and any obstacles that get in the way. As a purely vision-based robot, it can’t operate in low-light conditions. However, this is a good thing, as you should avoid any contact with nocturnal wildlife.
Data connection is purely Wi-Fi, unless you fork out extra for the 4G module. Bundled with two years of data, the 4G option lets you operate the robot outside Wi-Fi range. It’s an extra expense that also unlocks the C15’s anti-theft package. It’s a shame that this security feature is kept behind a paywall, but Eufy isn’t the first brand to take this approach.
With a cut height range of 20-to-60mm, this robot can cut a nice short lawn. Controlled manually by a dial on top of the robot, the cutting height adjustment is simple to operate, but you can’t cut different lawn zones at different heights. The cut width is a modest 18cm, but the robot can easily get into tight corners and between obstacles.
Integrated into Eufy’s powerful do-it-all app, you can control everything from the Omni E35 Robot Vacuum to the Video Doorbell Dual from one place. It’s a clean and simple app to use, with just enough customisation available to keep things interesting.
Something Eufy has added is remote control function. Unlike some robot lawnmowers, you can dial into the camera on the front of the C15. What’s more is you can remote control it from anywhere with an internet connection via the app. It transforms this little mower into a useful home security device. Gone out and think you’ve left the back window open? Take the C15 for a spin to check.
- Neat, parallel cut lines
- Obstacle avoidance is excellent
- Edges still need trimming
For lots of people, the thing that puts them off robot lawnmowers is having to deal with a complicated setup process. What makes the Eufy C15 an effective “drop and go” robot is that it’s incredibly easy to set up.
With no cumbersome RTK station to deal with, I simply took the robot from its box, powered up the garage, and connected the robot to the app. I didn’t need to drive it around or fiddle with maps before putting it to work.
Like my experience with the Eufy Lawnbot E15, getting started is effortless. So much so, there’s even a “map and mow” function. Just as it sounds, it doesn’t even wait until it’s mapped the whole lawn before getting to work.
The auto mapping function was just as impressive. The C15 drove around the lawn, spun around a few times, and produced a decent map of my test garden within about 15 minutes. Although it wasn’t as quick as a LiDAR-enabled robot like the Sunseeker Elite X4, it was accurate around flower borders and under trees.
Editing the map was simple. Adding the usual no-go zones and pathways between lawns was also easy to do. The “must mow” feature was useful too, I used it to ignore patches of weeds that were mistaken for flowers by the onboard cameras.
Due to the severe lack of rain this summer in my part of England, the Eufy C15 didn’t have as much grass to mow as I’d like. However, it did a fine job with what grass there was over several weeks.
Defaulting to mow parallel stripes, the robot orients itself in the direction that the dock points. It kept neatly to its lanes and only veered off to avoid obstacles like discarded balls on the grass. I changed the mowing pattern to alternating angle stripes to ensure a complete cut though.
Rather like the similarly priced (but more off-road capable) Mammotion Luba Mini AWD, the C15 doesn’t just grind around when it reaches the end of the lawn. Instead, it performs a three-point turn that would impress most driving instructors. This helps to avoid ripping up grass around the edge of the lawn, and it looks neat too.
Fairly zipping around the garden, I tested out the different travel and blade speeds, and it worked flawlessly on the flat. However, like other two-wheel-drive robots, it struggled to traverse a slope and got itself stuck in a hole in the lawn. If you have a rough garden, the C15 will struggle. The 18° slope capability does work, but only if it hits it head on. I’ve yet to find a two-wheel-drive robot lawnmower that can cope with traversing a slope.
Like most robots with vision-based navigation systems, the C15 gives the edges of the lawn a rather wide berth. Although you can adjust the perimeter, it maintains a safety buffer of around 10 cm. That meant I still had to strim the edges of the lawn and around obstacles for a less-than-messy finish.
Rated to cut just 500 m², this robot isn’t suited to huge lawns. And because it lacks an automatic height adjustment feature, it can’t cut different zones at different heights. However, the quality of the cut was excellent.
The robot struggled a few times when returning to its charging dock, producing some alarming wheel spin on the slick plastic. I had sited the dock on a very slight incline, but it didn’t feel like enough to stop it returning.
I tried out the remote control feature, and the quality of the picture via the app was decent, although there was a bit of lag when driving the mower around. Also, the Wi-Fi connection didn’t quite reach the bottom of my test garden. It didn’t affect the mowing pattern, but I was unable to remote control at the end of the lawn. For that, I’d need to spend another £99 for the 4G dongle.
Should you buy it?
You want a robot lawnmower that's easy to set up
Getting started is made as easy as possible with no RTK station to install
You want a robot that can tackle uneven ground and slopes
This nippy little white mower is aimed squarely at suburban homeowners who want a robot but without the fuss. It’s definitely not the best robot lawnmower for owners of sloped, undulating lawns though. And although it’s a shame that the 4G connectivity and theft-prevention technology is hidden behind a paywall, it’s a quality robot for less than a thousand pounds.
