Indicators from Roomba®
- e Series Model says "Drop off detected. Move to a new area, then press Clean Error
six (6)." - 600- 900 Series Roomba® says "Error six (6). Move Roomba® to a new location, then press CLEAN to restart."
- 500 Series Model will play a two-tone "Uh-Oh" sound followed by six (6) beeps.
If Roomba® indicates an Error six (6) occurred, it could be due to the following:
- Cliff Sensors are dirty
- Roomba® drove over a dark surface
- Roomba® became stuck over a cliff, such as the edge of a stair
- Roomba® got stuck on an uneven surface on the floor
Ensure the Cliff Sensors are clean
- Flip Roomba® over and wipe the Cliff sensors with a clean dry cloth.
- Place Roomba® down, then press CLEAN.
If the issue persists after cleaning the cliff sensors, please select from the following menu to determine the best way to troubleshoot this issue:
Roomba® stopped on a dark surface
Roomba’s Cliff Sensors can sometimes see dark surfaces as drop-offs. Instead of cleaning these areas, Roomba® may back away or spin to avoid the area, then say Error six (6).
Recommendation:
Use a Virtual Wall® to block off the area.
Roomba® got stuck on an edge
The minimum height to qualify as a “cliff” is 3.5 inches or 90 mm. Roomba® can interpret a rug hanging over a stair edge as a drop-off, and result in an Error six (6).
Recommendation:
- Adjust the placement of rugs, if necessary, to be flush with the stair edge.
- Move Roomba® to a new location, then press CLEAN.
- If the issue persists, use a Virtual Wall® to block off the area.
Roomba® stops in the middle of the floor
If Roomba® stops in the middle of the floor with an Error six (6) and is not on a dark surface or an edge, ensure the side brush is clean.
Recommendation:
- Move Roomba® to a new location, then Press CLEAN.
- Watch Roomba® to see if the Side Brush spins.
- If it doesn't, remove the side brush and clean out debris.
