eureka 2-in-one stick vac w rotating brush; what to do if the brush will not rotate

I found that the switch was to blame: it's located in an oval space in the housing, whereas it should be a rectangular opening; therefore the 2nd (first (1) Floor then (2) Carpet) setting (when the brush spins) is beyond the reach of the switch. Just take a box cutter or other sharp knife and cut away some of the plastic on the floor (downward) end of the vac switch opening and see if that helps. I took the machine apart expecting a bugger problem, but it was just the switch.
