Irobot roomba says "needs cleaning" even though it

Customer Question

Irobot roomba says "needs cleaning" even though it is well serviced.

Hi there,

If it has been well serviced and cleaned, then the dirt sensor may need cleaning, or it is faulty and needs repaired.

Try wiping the sensors - if there is no improvement, then it will need to be returned to iRobot for repair.

what does a dirt sensor look like?
Expert:  Pete replied 1 year ago.


It has a tiny glass lens which has a sensor behind it.
