Cleaner head

Abstract

A cleaner head 10 for a vacuum cleaner has a suction inlet 20 defined in the lower face of a housing 11 and a suction passageway 20A through the housing 11. A rotatable sealing element 40 is located at a front of the housing 11. The rotatable sealing element 40 has a rotational axis 41 which is parallel to the lower face of the cleaner head. An agitator 60 is positioned rewards of the rotatable sealing element 40. The suction passageway 20A is located between the agitator 60 and the rotatable sealing element 40.

Description

Background technique [0001] Vacuum cleaners are a common form of household appliances. Nowadays, most vacuum cleaners operate in a similar way in principle. The vacuum cleaner includes a vacuum cleaner head (pickup head) that is pushed across the surface, a separation system that separates dirt / dust from the airflow, and a suction source (usually a motor and impeller) to generate the airflow. Dirt / dust is drawn from the surface to be cleaned and entrained in the airflow. The dirty airflow is drawn from the head of the vacuum cleaner to the separation system. Clean air is discharged into the room. When the air is expelled, negative pressure is formed on the pickup head. [0002] There are many variants of the separation system: (filter bag, cyclone separator and water tank) and the size and design of the motor. [0003] Different types of floor surfaces present different challenges. For carpeted floors, it is known to use a vacuum cleaner head with an agitator, such as a beati...

Problems solved by technology

While it may provide good cleaning performance, this is more expensive and requires increased storage space for multiple cleaner heads, and requires additional time and hassle to replace cleaner heads

[0007] Vacuums with only a single cleaner head attempt to provide acceptable pickup quality across a range of floor types, but often achieve good pickup quality on only one surface type (carpeted floors or hard floors)
