  • Patent number: 11849904
    Abstract: A cleaner head for a vacuum cleaner has a housing, an agitator mounted within the housing, and a drive mechanism for driving the agitator about a first axis A. The drive mechanism is mounted to the housing for rotation about a second axis R. The second axis R is offset from the first axis A. When the agitator is brought into contact with a surface to be cleaned, the surface exerts a reaction torque on the agitator that causes the drive mechanism to rotate about the second axis R.

  • Patent number: 11839347
    Abstract: A flexible hose for use with surface cleaning devices is disclosed that includes a support structure that allows a user to collapse and lock the same into a storage configuration, and then easily unlock the same using a relatively minor amount of force, e.g., a user-applied pulling force or mechanical force. Thus, in a general sense, a hose consistent with the present disclosure may include two relatively stable/steady-state configurations, namely a storage configuration and an in-use configuration. Thus, the hose allows a user to collapse and lock the hose when not in use, and to transition the hose to an in-use configuration to target various types of surfaces to clean including, for instance, floors, walls and ceilings which may be many feet (e.g., up to 5 feet or more) from the surface cleaning apparatus.
