DIRECT ANSWER

Error 33 means the robot couldn't reach the area you sent it to and cancelled the job. A closed door, a moved couch or a dark hallway broke the route it had planned across the map.

COMMON CAUSES · RANKED

1

Door closed along the route MOST COMMON

The map says the room connects; the door says otherwise.

2

Furniture or clutter blocking the corridor

New obstacles between rooms cut off the planned path.

3

Route too dark to navigate

Camera-guided models lose their bearings crossing an unlit hallway.

HOW TO FIX IT

No battery or electrical work involved in this fix.

Open the route

Open doors and clear obstacles between the dock and the target room.

Light the way

Leave enough light along the route — dim is fine, pitch black is not.

Wipe the camera window

Dust on the lens degrades navigation. A dry microfiber cloth is enough.

Check the Smart Map

Make sure the target room is connected to the rest of the map and retry.
