Our verdict
It is built for big, fairly flat lawns. As of November 9, 2026 it is $500 above the typical RTK GPS mower, $3,799.99 (median of 4 RTK GPS mowers in our data), but $2,150 per acre is about 40% below the $3,573 median for the type. It lists a 9.4 inch cutting width, 62 dB noise, IPX5 water protection and a 39 lb weight.
The slope limit is the compromise. The Mammotion LUBA 2 AWD 10000HX (High) costs $4,499 for 2.5 acres and an 80% limit with all-wheel drive. The Husqvarna Automower 420 iQ is $3,299.99 for 1 acre with the same 45% limit and 4 years, if your lawn is half the size.
Choose it for a 2 acre lawn with gentle slopes and a 4 year warranty. If you have hills, step up to the Mammotion or look at the Worx 4WD models.
