Prior to the addition of grippy tape, the roomba cage was sharp, and easily able to scratch metal surfaces. One user known as Caydu took advantage of this and scratched the heck out of the furnace and the air duct.

a user named caydu would directly transport very loud noises to every heated room in the house above Carpet's Basement by ramming into the air duct repeatedly.

roombas got stuck many many many times. One user, known as Caydu, even managed to get all three roombas stuck simultaneously, MULTIPLE TIMES!

a driver named Sussy Baka managed to move carpet's drawers near his workbench. several times. carpet removed the wheels, but it was no use, as it didnt stop sussy baka. Carpet then screwed the drawers in with a single screw, but this driver figured out how to open one of the drawers for leverage, and then use that leverage to turn the drawer set back and forth repeatedly until the screw broke free, freeing the drawer set to be moved once again.
