Our verdict
The bottom line
A genuinely interesting alternative to the Husqvarna 305 if you do not want to lay boundary wire. RTK works well in open suburban gardens; less reliable near trees or fences.

Buying second-hand
Used-market tip
£800–1200 used. Most YUKA Mini units are still under warranty — confirm purchase date with the seller. RTK base station must be included. Test it cuts a full perimeter before paying — RTK setup can be fragile. Mammotion accounts must be reset by seller.
Where to look: Facebook Marketplace and Gumtree are usually 20–30% cheaper than eBay UK for petrol mowers because most sellers want local pickup. eBay tends to win on cordless and electric (lighter, easier to ship). Always insist on a starting demonstration before paying.
