<p>A vacuum cleaner (10) includes a housing (14), an agitator brush (40) mounted for relative rotation in the housing (14) and a motor (30) including a shaft (42) for driving the agitator brush (40). A flexible belt (44) connects the drive shaft (42) of the motor (30) to the agitator brush (40). Further, a mechanism (50) is provided for disconnecting the belt (44) from either the motor drive shaft (42) or the agitator brush (40). That mechanism (50) includes an element or lug (54) carried on a shifter (52) and an actuator (56) for selectively displacing the shifter (52) and element/lug (54) carried thereon between a first position wherein the element/lug (54) is out of engagement with said belt (44) and a second position wherein the element/lug (54) engages the belt (44), thereby forcing the belt (44) out of engagement with either the motor drive shaft (42) or the agitator brush (40).</p> |
