Is a second-hand Ecovacs GOAT G1 worth buying now it's discontinued?

Only at a clear discount and only if the kit is complete. The Ecovacs GOAT G1 is no longer sold new in the UK: its product page says it's sold out and points buyers to other GOAT models, and it has dropped off Ecovacs' UK mower hub and support model list. That last point is the one to weigh most, because help with faults and software may get harder to find as time passes.

Before handing over money, check:

• Both UWB beacons and their power supplies. The G1 positions itself with cameras plus two radio beacons placed around the garden, and it won't navigate as designed without them.
• The charging station and cables, plus the cellular module if the listing mentions 4G. That was an optional extra.
• Battery health. Ask how long a typical session lasts now, and when the mower was bought.
• Proof of purchase. Sold new, the G1 carried a warranty of 3 years on the robot, running from the original sale date, so any remaining cover depends on that receipt.

Also bear in mind the specifications. Ecovacs rated it for 800 m², but never published a maximum slope on its UK pages, and the cut height tops out at 60 mm.

Its last UK list price was £999, more than a new Ecovacs GOAT O RTK (O600 RTK / O800 RTK) costs, so a used G1 needs to be well below that to make sense. Our wire-free hub lists current alternatives.
