Pros & cons
Sunseeker X5 AWD
- ✓AWD and suspension climb 60% banks and roll over roots and bumps that stall two-wheel mowers
- ✓Offset edge blade trims to 1.2 in of fences and driveways, cutting the weekly string-trimmer chore
- ✓Twin cameras keep it on line under trees where RTK alone drops out
- ✓Floating deck follows uneven ground without scalping
- ✓100 zones, corridors and no-go areas mapped from the app in about 20 minutes
- ✗Runtime, charge time and weight are not published for the US model
- ✗Needs the RTK base station mounted with open sky; firmware updates must land before it links
- ✗Roborock RockMow X1 offers twice the rated area and 80% slopes at the same price
- ✗GPS tracking costs extra via the 4G module
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
