摘要： A surface cleaning apparatus including a body defining an agitation chamber, an agitator partially disposed within the agitation chamber and configured to rotate about a pivot axis, and a debrider at least partially disposed within the agitation chamber. The agitator includes an elongated body having a first and a second end, a sidewall extending radially outward from the elongated body extending between the first and the second ends, and a plurality of bristles extending radially outward from the elongated body. The plurality of bristles are arranged in at least one row adjacent to the sidewall. The debrider includes a plurality of teeth configured to contact a portion of the sidewall as the agitator rotates about the pivot axis.

摘要： A surface cleaning device includes a nozzle and an odor dial assembly. The nozzle includes a nozzle housing and a dirty air passageway. The odor dial assembly include a fragrance member and a dial body configured to be removably coupled to the nozzle housing. The dial body at least partially defines a fragrance cavity configured to at least partially receive the fragrance member and a fragrance passageway extending therethrough. The odor dial assembly is configured to transition between a plurality of user-selectable positions to adjust an amount of fragrance particles released by the fragrance member into the dirty air passageway.
