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.
