The rated lawn area is how much grass the brand says this mower can keep cut. It mows, returns to its charging base to recharge, then goes back out to mow again. A lawn bigger than the rated area will not damage the mower. It cannot reach every part of the lawn often enough, so grass at the far end grows too tall between cuts. Brands rate each mower for the steepest ground it can handle. Do not go past that rating. On ground steeper than that, the mower can slip.

This mower suits a small lawn with a steep bank or two and some shade from trees. Mammotion rates it for up to 0.37 acre1,500 m². Beds, paths and tight corners slow any mower down, so we take about 20% off that rating. Plan on about 0.3 acre1,200 m² of grass.
Pick it first for a steep bank. All four wheels drive, and Mammotion rates it for a much steeper climb than most mowers we cover. Trees are the second reason. It finds its way with a laser and cameras, without satellites, so branches overhead do not get in its way.
If your lawn is flat and open, you do not need all-wheel drive, and you can spend less. If it is bigger than about 0.3 acre1,200 m², look at our LUBA 3 review. That is Mammotion’s larger mower, and it is rated for the same slope.

Mammotion rates the LUBA mini 2 to climb ground that rises 80 ft80 m for every 100 ft100 m forward. That is about 39 degrees. No mower we cover is rated for steeper ground, and only the LUBA 3 matches it.
Dew and rain make grass slippery, and a wet slope gives the wheels less grip. So we take about 15% off the rating. On a damp morning, plan on about 68 ft68 m of rise per 100 ft100 m.
Mammotion rates the mower for a gentler slope along the edge of the lawn. Its user manual rates it for a rise of 40 ft40 m per 100 ft100 m there. Take off our 15% for wet grass, and plan on about 34 ft34 m per 100 ft100 m.
Some brands we cover publish a separate slope rating for the edge of the lawn. Among the mowers with an edge rating, this one is rated highest. The rest are rated for 20 ft20 m per 100 ft100 m or less.
How does it find its way without a wire?
Older robot mowers need a boundary wire, buried around the lawn for them to follow. Many newer ones use satellites instead, and those need open sky over the lawn. The LUBA mini 2 does neither.
It carries a lidar scanner, which scans all the way around it. NOAA describes lidar as a pulsed laser that measures distances. From those distances, the mower builds a map of every tree, fence and flower bed in the yard. Mammotion says the scanner sees up to 200 ft61 m away. Two cameras watch for things in its path, such as garden furniture or a pet, so it can steer around them.
You set it up by making a map in the Mammotion app. Mammotion says you can make the map yourself, or let the app do it for you. Once the map is done, the mower can start cutting.
One map can hold up to 20 separate lawn areas, with paths between them. That helps if a driveway splits your front lawn from the back. If you dig a new bed later, you change the map in the app. You don’t have to map the whole yard again.
Will it cut your grass at the right height?
The 1500H cuts grass to between 2.2 in6 cm and 4 in10 cm tall. Mammotion calls it the High Version. That suits grass you keep long. Clemson Extension’s mowing table says to keep Saint Augustine grass between 2.5 in6 cm and 4 in10 cm tall. It puts tall fescue at 3 in8 cm to 3.5 in9 cm for summer.
Other grasses need a much shorter cut. The same table lists zoysia at 1 in3 cm to 2 in5 cm, centipede at 1.5 in4 cm to 2 in5 cm, and hybrid Bermuda at 0.5 in1 cm to 1.5 in4 cm. The 1500H cannot cut that low. Mammotion also sells a Standard version that cuts 0.8 in2 cm to 2.6 in7 cm. We do not link to that version.
A second blade disc trims the edges. It is 4.7 in12 cm across, and Mammotion says it mows to within about 2.1 in5 cm of a wall. So plan on a thin strip along walls and fences that you trim by hand.
What is it like to live with?
Mammotion says one charge mows up to 0.12 acre490 m². So a lawn of the full 0.37 acre1,500 m² takes more than three charges to finish. On a lawn that size, give it a long mowing window in the app’s schedule.
It has a cell connection built in. You can start it, stop it or check on it from the app. That works even when you are far from home. The first three years of data come free. Then the plan needs renewing, so ask Mammotion what that costs before you buy.
Is it worth it?
Yes, if you have a small lawn, up to about 0.3 acre1,200 m², with steep ground and trees overhead. Among the mowers we cover, only the LUBA 3 is rated for the same climb. It costs a lot more, so for a small yard I’d pick the LUBA mini 2.
If your hill is gentler, a cheaper laser mower may do. Our i215 LiDAR and LUBA mini 2 comparison gives the slope each one can climb.
Before you order, measure the slope in the middle of the lawn and along its edge. Then check your grass type against the 2.2 in6 cm to 4 in10 cm that this version cuts.
