Patent Images
1. A vacuum cleaner comprising:
- a cleaning head assembly having a suction nozzle adapted to be moved along a surface to be cleaned;
a hair collection assembly having a hair collection element adapted to collect hair from the surface to be cleaned, wherein the hair collection assembly is mounted to the cleaning head for movement of the hair collection element between a first position in which the hair collection element is in contact with the surface to be cleaned, and a second position, in which the hair collection element is spaced from the surface to be cleaned; and
a latch assembly mounted to the cleaning head and the hair collection assembly to selectively retain the hair collection assembly in contact with the surface to be cleaned.

Abstract
A vacuum cleaner with a cyclone module assembly comprises a cyclone separation chamber for separating dust and debris from air, a dirt cup for collecting dust and debris that is separated from the air in the cyclone separation chamber, wherein the separation chamber further includes an exhaust grill with apertures formed at an acute angle relative to the working air flow. In an alternate embodiment, the vacuum cleaner further includes a hair collection assembly that can be latched in one of the engaged and disengaged positions. In yet another embodiment, the dirt cup is sealingly biased to the cyclone separation chamber by a cam or a coil spring.

8. A vacuum cleaner comprising:
-
a cleaning head assembly having a suction nozzle; a suction source to create a flow of working air; a cyclone module assembly in fluid communication with the suction nozzle and the suction source, and comprising; a cyclone separation chamber for separating dust and debris from air, the cyclone separation chamber having an inlet opening in fluid communication with the suction nozzle through the working air path, an outlet opening for discharging cleaned air and a particle discharge outlet for discharging dust and debris separated from air; a dirt cup in fluid communication with the particle discharge outlet for collecting dust and debris that is separated from the air in the cyclone separation chamber; and an exhaust grill in the cyclone separation chamber to filter out larger debris, the exhaust grill comprising a plurality of apertures whereby a leading edge of the aperture forms an acute angle relative to the flow of working air. - View Dependent Claims (9, 13)
