Question about iRobot Roomba 440 Cordless Robot Vacuum
When "clean" or "spot" bottoms depressed, Roomba will only backup (as if contacting an object) or move about 6 inches in a circle, then begin backing up again. The bumper and cliff sensors are clear of debris.

You will need to take the top off to clear those wheels.
This happens a lot when cleaning new carpet. The fuzz jams the wheel switch, and dosey do you go.

Yes, this is known issue and if your bumper moves freely, you might be facing a sensor fault caused by poor quality of components.
Here is a guide to fix it
