    摘要： A vacuum cleaner includes an electric blower for generating a suction air stream and a dust collecting unit for collecting dirt particles contained in the suction air stream. The suction air stream passing through the dust collecting unit into the electric blower flows in an approximately linear path. A dust removing unit is provided for removing dirt particles adhered to the dust collecting unit. The dust removing unit is preferably disposed adjacent to a communication hole between the dust collecting chamber and an electric blower chamber.

    摘要： A bagless vacuum cleaner (10) includes a nozzle assembly (16) having a suction nozzle for picking up dirt and debris from a surface to be cleaned and a canister assembly (18) including a cavity (32). A dust collection assembly (12) is received and held in that cavity (32). The dust collection assembly (12) includes a filtering subassembly (100) and a dust container (102). The dust container (102) has an open top (104), a bottom wall (106), a first cylindrical sidewall (108), an inlet (110), and a downwardly directed outlet (112) extending through the bottom wall. An airstream conduit is provided for conveying a vacuum airstream between the suction nozzle and the inlet. A filter (124, 138) is carried on the filtering subassembly (100). A sweeper (200) rotates relative to the filtering subassembly (100) to clean dirt and debris from at least a portion of the filter (138). A suction fan (34) and suction fan drive motor (35) carried on either the nozzle assembly (16) or the canister assembly (18) generates the vacuum airstream for drawing dirt and debris through the suction nozzle, the airstream conduit and the dust container (102).

    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.
