Your vacuum's LiDAR is probably fine.

Unless you see physical damage (cracked housing, wonky turret), just remap the house and move on. The Dreame L10s Ultra self-calibrates during a new cleaning cycle.

Here’s what I’d do: power cycle the robot (unplug dock, remove battery for 10 seconds if possible, then plug back in). Then start a full cleaning run from the app and let it map the room fresh. The LiDAR recalibrates automatically as it spins up.

If the map still looks janky or the robot seems confused, go to Settings > Advanced Settings > Sensor Calibration in the app. Some models hide this under “Maintenance.” Run that. It takes a minute.

Only if that fails would I consider a factory reset (Settings > Factory Reset). But honestly, a hard fall usually just knocks a few screws loose inside — you’d hear rattling. If not, it’s fine.

Don’t waste an afternoon on this. A ten-minute remap is all you need.
