## Verdict

The Lymow One cuts more like a walk behind mower than a typical robot, and its tracks climb stumps, roots and steep banks. It is heavy at about 78 lb, louder than disc mowers and needs an RTK antenna. Buy it for big, rough or hilly yards, not a small flat lawn.

## Pros

- 16 in deck with real mower blades
- Tracks handled stumps and steep banks in testing
- Long runtime from a 15Ah LiFePO4 battery
- Up to 80 zones and built in 4G

## Cons

- Heavy at about 78 lb
- Louder than typical robot mowers
- Needs an RTK antenna with clear sky
- Proprietary blades, no spares included
- Removable battery is a theft risk

## Questions buyers ask

### Does it need an RTK antenna?

Yes. It uses an RTK base station plus VSLAM cameras, so the antenna needs a clear view of the sky. No boundary wire is needed.

### How loud is it?

Lymow does not list a figure. Freshly Charged cites 68 dB and both reviewers said it is louder than disc blade robot mowers.

### What is the difference between the 5A and 10A versions?

The charger. Lymow says the 10A model charges to 90% in about 90 minutes and covers up to 1.73 acres a day, while the 5A model takes about 150 minutes and covers about 1.1 acres a day.
