Pros & cons
MOVA LiDAX Ultra
- ✓No RTK station, wire or sky view needed; LiDAR maps under trees and beside the house
- ✓Clean, quiet cut once mapped, with a 1.2 to 3.9 in electric height range and edge trimming
- ✓Half-acre four-zone yard finished in about two hours on the 2000, per a tester
- ✓Dual maps and up to 150 zones handle front, back and side yards separately
- ✓Cheapest LiDAR route into the Dreame hardware family, with up to a 3-year warranty
- ✗Front casters hang up on sand, soft ground and two-inch transitions; one reviewer called the 1000 unusable on sandy grass
- ✗Two-wheel drive spins and digs on soft slopes; the 45 percent rating assumes firm turf
- ✗Obstacle avoidance missed a 6 in stone wall and misidentified a sprinkler as a bird
- ✗Setup takes patience: multiple remaps and heavy no-go zoning before it settled
- ✗Ultra 1000 has no 4G unless you buy the $119 Link module, and its 4 Ah pack runs 60 to 80 minutes
Sunseeker S4
- ✓No antenna, no wire: LiDAR maps and positions under tree canopy where GPS mowers drift
- ✓Auto-mapped a two-zone yard on the first try; the app shows the 3D LiDAR map it built
- ✓Reliably rerouted around a dog and a golf-ball-sized toy in a month-long test
- ✓Fits through 31.5 in passages and stores 100 zones across 5 maps
- ✓Cheapest LiDAR mower from an established brand, $500 under the Ecovacs O1000 LiDAR Pro
- ✗Blades sit 4.3 in inside the housing, so it leaves an uncut strip at every edge
- ✗7 in deck and 90 minute runtime mean a quarter acre takes several charge cycles
- ✗One review unit died after a night in standing water despite the IPX6 rating
- ✗GPS tracking needs the extra-cost 4G module
