ROOMBA·FAULT ERR 33 WARN
Roomba Error 33 — Path to target blocked
Severity: Warning — job cancelled — the robot couldn't reach where you sent it ijs
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.
