Abstract
An upright vacuum cleaner has a removable powered brush vacuum nozzle which can be removed and replaced without operation of a belt lifter. The power linkage from the cleaner's fan motor to the nozzle brush includes a positive-drive clutch, and control means active at the inception of each operation of the cleaner in the brush-and-vacuum mode to engage the clutch prior to starting the fan motor and active at the conclusion of operation of the cleaner in the brush-and-vacuum mode to disengage the clutch only after stopping the fan motor.
