Which robot mower works under trees?

If the canopy is over your mower's path, that's the problem, not a tree sitting at the edge of an open lawn. A satellite fix weakens under that cover. We'd read a LiDAR model for the shaded part of your yard. An RTK mower can still be the right machine for the open part.

Where the fix weakens
Your mower needs sky along its path, not only at an antenna out in the open. How RTK, LiDAR, and vision fail.

| Model | Rated | Slope | Navigation | For canopy |
|---|---|---|---|---|
| LUBA 3 AWD 3000 | 0.75 acres (32,670 sq ft) | 80% (38.6°) | LiDAR, Network RTK, Vision | Yes, for the shaded part. LiDAR plus network RTK. |
| Dreame A3 AWD Pro 2500 | 0.62 acres (27,007 sq ft) | 80% (38.7°) | LiDAR, Vision | Yes, for the shaded part. LiDAR and vision, and there's no RTK. |
| LUBA mini 2 AWD 1500H | 0.37 acres (16,117 sq ft) | 80% (38.6°) | LiDAR, Vision | Yes, on a smaller lawn. It's LiDAR and vision. |
| LiDAX Ultra 2000 | 0.5 acres (21,780 sq ft) | 45% (degrees not published) | LiDAR, Vision | Yes. LiDAR and vision. Few owner reports yet, so read the review before you order. |
| Navimow i210 AWD | 0.25 acres (10,890 sq ft) | 45% (24°) | Network RTK, Vision | The open part of your yard only. Network RTK and vision. |
| RockNeo Q110H | 0.25 acres (10,890 sq ft) | 45% (24.2°) | Antenna or network RTK, V-SLAM, Vision | The open part of your yard only. It's RTK-led. |
Makers usually publish one maximum slope and don't say whether it applies in the middle of your lawn or at the edge. When a model also gives a lower figure for the edge, that's the one to use there. If your bank runs into a bed or a fence, we'd leave some margin, because edges are usually harder.
The i210 is rated 0.25 acres (10,890 sq ft) and doesn't use an antenna. Canopy can still weaken network RTK, which is why heavy tree cover is on its skip list. We'd use it for the open quarter acre, and a LiDAR model for the shaded part if that part is large enough to need its own mower. The Q110H is the same kind of split: RTK plus VSLAM, rated 0.25 acres.
