Mammotion LUBA 3 AWD 3000H

Should you buy the Mammotion LUBA 3 AWD 3000H?

The Mammotion LUBA 3 AWD 3000H is for someone with up to three quarters of an acre of hilly, tree-shaded, awkward lawn who wants the mower that can handle all of it. At $2,799 it ranks #4 of 10 robot lawn mowers. Tri-Fusion navigation stacks LiDAR, network RTK and camera vision, so it does not depend on any one of them. If your lawn is flat, the ECOVACS A3000 does the job for $300 less with an edge trimmer. If you have hills but a smaller lawn, the LUBA mini 2 is the same idea at $1,999.

Where it earns its score

• Highest Features score, tied. Features hit 96 on 360-degree LiDAR plus iNavi NetRTK plus dual-camera AI vision, with no physical antenna.
• Steep slopes. An 80 percent (38.6 degree) rating with AWD and independent hub motors.
• Longest runtime here. A 12 Ah battery runs up to 175 minutes per charge and mows about 5,400 square feet per hour.
• Up to 30 zones. With a live camera feed in the app and built-in 4G.

What to know first

• Value is the lowest factor. At 66, it is the second-lowest Value in the category behind the Husqvarna.
• RTK may cost money later. The iNavi service and 4G data are free for 3 years; after that a paid plan may be required.
• High-cut version only. The 3000H cuts 2.2 to 4.0 inches, so it is not the model for a very short lawn.
• Warranty scores 75. Fine, but the Husqvarna's 4 years is the benchmark.
