Our verdict
The LUBA 3 costs a lot for a small lawn. As of November 9, 2026 it is $400 above the typical RTK GPS plus LiDAR mower, $1,999 (median of 8 in our data). At $6,484 per acre it is about 30% above that type's $4,997 median. It lists 70 dB noise, among the loudest in our data, along with IPX6 water protection and 215 minutes per charge.
For a similar acreage the Segway Navimow i215 LiDAR is $1,399 for 0.37 acre and a 45% limit, with no antenna, quieter at 59 dB but no all-wheel drive. The Worx Landroid Vision Cloud 4WD 1/2 Acre (WR342) is $2,299.99 for 0.5 acre, an 84% limit and all-wheel drive.
Choose it for a small, steep lawn where you want both LiDAR and RTK with no antenna. For a gentle lawn, the Navimow costs $1,000 less.

Robot Mowers on Slopes
Slope ratings come in percent or degrees, and a 45 percent rating is only about 24 degrees. Measure your steepest spot and convert it before you trust a rating.
RTK vs LiDAR vs Camera Robot Mowers
Robot mowers navigate by wire, RTK, LiDAR, cameras or a mix. Your tree cover, sky view and patience for setup decide which one fits your yard.
How to Choose a Robot Lawn Mower
Start with your lawn, not the spec sheet: measure the grass, the steepest slope, the tree cover and the tightest passage. Those four numbers narrow the list.
