It works on the "bare floor" switch, but not on the "carpet" (ie:
light does not come on and the roller is not turning).
I did check the belt - hadn't slipped or worn, from what I could tell.

Most of that type of unit has a reset of some sort, perhaps right on the
head itself. The owners manual probably point it out in the troubleshooting
section.
