A proper self-charging robot from Gardena for under £400. You pay with your time instead: laying and pegging the 150 m wire.

- Cheap way to get a proper docking robot from a major garden brand
- Wire guidance is very predictable once laid
- Quiet
What to know
- You must lay and peg a boundary wire
- Bluetooth app only works within about 10 m
- US availability not confirmed
