ComparisonGardena smart Sileno free 600 and Ecovacs GOAT O1200 LiDAR PRO

Wire-free satellite positioning removes the trench-digging step, but independent testing of this exact model documents the owner retrieving it from the lawn every morning.

Rear twin-disc cutting trims the lawn edge the wire-guided SILENO models cannot reach, yet GPS reception is reported unreliable under small trees and near the house.

A published European price sits inside Gardena’s existing support range, though no US channel exists, so American buyers have no domestic warranty or parts path.

The wire-free LiDAR and camera mapping removes trenching, and it leans on physical landmarks rather than RTK satellites, so wide featureless lawns give it fewer references.

Edge trimming close to borders reduces hand finishing, while the 22 cm cutting deck covers dense or overgrown turf slowly rather than quickly.

Coverage ceiling of about 1,200 square meters: a single machine fits a third-of-an-acre lawn and stops short of larger properties.

Yards with small trees or house-adjacent edges

A hands-on test of this exact model documents GPS reception failing specifically under small trees and along the edges of the house, both common garden features.

Buyers located in the United States

Gardena lists the SILENO free range on its international and European sites only, with a euro list price and no domestic warranty or parts channel.

Owners who need daily unattended operation

A hands-on review reports the owner carrying the machine back to its base every morning, meaning it is not finishing its job unattended the way the rating implies.

Buyers wanting a proven boundary-accuracy record

No independent test of boundary accuracy or cut quality exists beyond that hands-on review, which specifically attributes the machine's failures to unreliable satellite reception under tree cover.

Large lawns over about half an acre

Rated coverage tops out near 1,200 square meters, so bigger properties outrun its mapped area and would need a higher-capacity machine or a second unit.

Owners who require a buried perimeter wire

Boundaries are set only through wire-free LiDAR and camera mapping; there is no perimeter-wire mode for those who prefer a physical buried boundary.

Very large open lawns needing long single runs

Runtime reaches about 90 minutes before a roughly 70-minute recharge, so extensive lawns require several charge cycles across a single mowing session.

Wide featureless fields relying on satellite positioning

Navigation uses LiDAR and camera landmarks rather than RTK satellite positioning, so wide open expanses with few references give the mapping less to lock onto.

Lawns kept very tall between cuts

Cutting height adjusts between 3 and 8 centimeters, so heavily overgrown grass needs a separate initial trim before scheduled runs become effective.
