Our verdict
The bottom line
The right robot for a small flat suburban lawn. Quiet, neat, reliable, and Gardena have been making robots for years. If your lawn is under 250m², it is the safer choice over the new Mammotion or Segway entry models.

Buying second-hand
Used-market tip
£170–340 used. Boundary wire integrity check as always. Gardena dock contacts are gold-plated and rarely corrode — that is a quality marker. Confirm the seller has the original cutting blades stored (they wear and 4-pack costs £15). Reset the Gardena Smart app before purchase.
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.
