Best robot mowers under £800

In its favour

• CorridorCut is designed for narrow spaces and dead ends, common in small UK gardens.
• 57 dB(A) is a low noise figure for mowing close to the house.
• Sold with a UK plug, 150 m of wire and an English manual.

Good to know

• Bluetooth app range is up to 10 m, so no remote control from work.
• No slope figure is given in the listing.

In its favour

• No boundary wire to bury, and the listing quotes a setup time of about five minutes.
• Rated for 45% slopes and passages as narrow as about 70 cm (2.3 ft).
• Zones, no-go areas, cutting height and schedules are all set in the Ecovacs app.

Good to know

• The listing is written for the US market, so check the plug and UK support first.
• RTK mowers need a clear view of the sky, and the listing does not explain what is included for that.

In its favour

• No guide wire needed for narrow passages, according to the listing.
• An 18 cm cut is wide for a robot rated at only 300 m².
• Remote control and scheduling through the Worx app.

Good to know

• The listing does not give a noise level.
• No slope figure is stated, so check the manual if your lawn is not flat.

In its favour

• No boundary wire or base to install, according to Bosch.
• Handles multiple small lawns and zones up to 100 m² in total.
• Cutting height adjusts from 20 to 60 mm.

Good to know

• Battery not included, so budget for one if you do not own the platform.
• Too small for a lawn much over 100 m², as that is its rated maximum.

In its favour

• Rated for 35% slopes, which is about 19 degrees.
• Wi-Fi app control lets you pause mowing when a slope is too wet.
• Multi-zone management covers separate areas, such as a top and bottom lawn.

Good to know

• 35% is the lowest slope figure in this guide, so it suits gentle slopes.

In its favour

• The listing gives a noise level of 57 dB(A), low enough for mowing near a patio or neighbours.
• Rated for slopes up to 35% and narrow spaces, handy on terraced and townhouse plots.
• Everything needed for DIY installation, including boundary wire, comes in the box.

Good to know

• Bluetooth app control works only near the mower, so you cannot check it from work.
• This listing is the US version (15001-41), so confirm the charging station plug suits UK sockets.

In its favour

• Double the rated area of the 250 model with the same quiet 57 dB(A) noise level.
• Cutting height adjusts from 20 to 45 mm in five positions, according to the specs.
