摘要：
An upright vacuum cleaner includes a nozzle assembly, a canister assembly pivotally mounted to said nozzle assembly, a suction fan and motor and a biaser. The biaser has a first end that engages the nozzle assembly and a second end that engages the canister assembly. The biaser provides a positive downforce urging the forward end of the nozzle assembly toward the surface being cleaned.
