Best Robot Mower with Built-in Edge Trimmer (2026)

Until 2026, no robot mower had a built-in edge trimmer. That changed with the ECOVACS Goat O1000 LiDAR PRO. This guide covers the only robot mower with a true edge-trimming solution — and what's coming next.

The Only Option: ECOVACS Goat O1000 LiDAR PRO

As of mid-2026, the ECOVACS Goat O1000 LiDAR PRO ($1,999) is the only robot mower with a built-in edge trimmer. Its TruEdge system uses a string trimmer that automatically extends to cut the edge as the mower drives along fences, walls, and garden beds. This eliminates 80-90% of manual edge work — a genuine game-changer.

How TruEdge Works

The TruEdge trimmer is a small string trimmer mounted on the side of the mower. When the mower detects it's driving along an edge (using its LiDAR + AI Vision), it extends the trimmer to cut the 2-4 inch strip that the cutting deck can't reach. When the mower is in open lawn, the trimmer retracts. The trimmer line needs replacement every 2-4 weeks during growing season ($10-$15 per pack).

What TruEdge Doesn't Do

The TruEdge trimmer doesn't eliminate all manual trimming: (1) Around trees and posts, the mower can't get close enough for the trimmer to work — you'll need to manual trim these spots. (2) In tight corners, the trimmer may not reach. (3) The trimmer line isn't strong enough for woody brush — use a dedicated string trimmer for that. Expect to do 10-20% of the edge work manually.

Future Options (Coming 2027-2028)

Other manufacturers are developing edge-trimming solutions: (1) Segway is rumored to be working on a Navimow with edge trimmer for 2027. (2) Mammotion has filed patents for a LUBA with edge trimmer. (3) Worx is developing a Landroid Vision with edge trimmer. Expect 3-4 robot mowers with built-in trimmers by end of 2027.

Is the ECOVACS Goat O1000 Worth It?

If you hate edge trimming, yes — at $1,999, it's a reasonable price for solving the #1 robot mower complaint. For buyers who don't mind string trimming every 2-4 weeks, a cheaper mower ($1,499-$1,999) plus a $200 battery string trimmer is a better value. The TruEdge trimmer adds about $200 to the mower's effective cost vs. a similar non-trimmer mower.
