Sanyo Dirt Hunter canister vacuum... .power brush had hair and thread wrapped around it..so..I took out the two screws and cut and pulled the hair etc out and now I can't get the damned thing back together..there is a 'toe button' to tap to switch from carpet to bare floors..that could be what is getting in the way...I realize it is not a new appliance, but, for the same reason, yesterday, I had to scrap my newer vacuum and this one is my back-up. Kinda need it to work for a few more weeks!
