Pros & cons
Sunseeker V3
- ✓Cheapest wire-free mower here at $599.99 on sale
- ✓Genuinely no setup: reviewers were mowing within minutes of screwing down the dock
- ✓Camera obstacle avoidance handled balls, people and a cat in testing
- ✓Camera wipers, rain delay and IPX5 keep the vision system working in wet weather
- ✓55 dB is quiet enough for evening runs without bothering neighbors
- ✗No map, so no zones, no-go areas or scheduled sections; only magnetic strip and arrow pads
- ✗Narrow 7.1 in random-pattern cut needs long sessions even on a small lawn
- ✗Central disc leaves edges for a string trimmer
- ✗Gets stuck in dips and holes; a flat lawn is a requirement, not a preference
- ✗No 4G or GPS tracking, and cutting height is a manual dial
Ecovacs GOAT GX-600
- ✓Fastest setup in the category: press start and it learns the boundary itself
- ✓No RTK antenna to mount and no signal worries under trees
- ✓Quiet (under 59 dB) and rain-aware, so it can run while you are home
- ✓Usually $999.99 on Ecovacs' store, well under the $1,299.99 list price
- ✓Two-year warranty on the mower is longer than Ecovacs' standard policy
- ✗No map: no zones, no no-go areas, no travel paths to a second lawn
- ✗Needs obvious physical borders; open edges onto a neighbor's grass confuse it
- ✗Cutting height is a manual dial, not app-adjustable
- ✗Not sold through US big-box or marketplace retailers, so there are no retail reviews to lean on
