Abstract: 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.

Abstract: An upright vacuum cleaner includes a nozzle assembly, a canister assembly pivotally mounted to said nozzle assembly, a suction fan and drive 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.

Abstract: 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 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).

A sweeper (200) rotates relative to the filtering subassembly (100) to clean dirt and debris from at least a portion of the filter (138).

Abstract: 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.

Abstract: A vacuum cleaner arrangement includes a cleaner main body accommodating a secondary battery and a blower, and having a terminal connector. The arrangement also includes a charger having a charging terminal to be connected to the terminal connector for charging the cleaner main body, and the charger has a box portion accommodating a power transformer. A notice device is on the charger to indicate when the charging terminal is connected to the terminal connector such that power can be supplied from the charging terminal to the terminal connector. The charging terminal is positioned adjacent a side wall of the box portion.

Abstract: In the invention, a brush body 30 that is rotated and driven by a motor 32 is disposed in a suction unit 2, and dust is sucked from the suction unit 2 by a blower 4, while exhaust of the blower 4 is sent to the suction unit 2 side through an exhaust passage 27. While the exhaust of the blower 4 is blown to the motor 32 exhaust is blown to the floor for lifting the dust from the floor to enhance the dust collection efficiency, and moreover, if the output of the motor 32 for driving the brush 30 is increased, temperature rise of the motor 32 can be suppressed, and thus durability may be enhanced.
