摘要： A convertible vacuum cleaner includes a nozzle base and a motor and filter housing rotatably mounted on the nozzle base. The nozzle base is movable along a floor surface and includes a brush cleaner for mounting a rotatable brush and a first suction passage communicating with the brush chamber at one end and with an exterior periphery of the nozzle base at the other end. The motor and filter housing includes a second suction passage communicating at a first end with the first suction passage second end and at a second end with an exterior periphery of the motor and filter housing. The motor chamber is formed in the motor and filter housing in spaced relation to the second suction passage. A suction chamber is disposed in the motor and filter housing in a spaced manner from the second suction passage and the motor chamber. The suction chamber has an inlet port communicating with the exterior periphery of the motor and filter housing. A flexible hose is mounted outside the motor and filter housing, the hose having a first end communicating with the second suction passage second end and a second end communicating with the suction chamber inlet port. The flexible hose first end can be selectively removed from communication with the second suction passage to enable the vacuum cleaner to be used with associated cleaning tools.

摘要： An air path for a vacuum cleaner, such as a stick type or broom type vacuum cleaner includes a first fan shell section having a first end at which is located a suction opening and a second end. A second fan shell section has a first end and a second end at which is located an outlet opening. An air outlet tube is located at the outlet opening of, and is of one piece with, the second fan shell section. The two fan shell sections are secured to each other in order to define a chamber between them. A suction fan is located in the chamber for drawing a suction at the suction opening and directing air through the air outlet tube.
