How it scores
The rating comes from 6 measured or published factors, each scored 0-100 against fixed reference points for its size. How we rank explains each one.
Independent tests
What independent reviewers measured in their own yards. Lawns, grass and settings differ, so these are reported as written and not scored.
| Tested by | Conditions |
|---|---|
| Notebookcheck | Covered almost 300 m² per charge. Recharging took about 2 hours, with just under 110 Wh drawn (peak 55 W) and about 7 W on standby. The cutting disc sits about 9 cm in from the body edge, which leaves an uncut strip. It struggled on rough or uneven ground. |
