摘要： A bypass valve may include a body defining a dirty air passageway, a nozzle coupling port configured to fluidly couple the dirty air passageway to a nozzle of the surface cleaning device, a wand coupling port configured to fluidly couple the dirty air passageway to a wand of the surface cleaning device, a suction coupling port configured to fluidly couple the dirty air passageway with a suction motor of the surface cleaning device, a wand receptacle configured to removably couple to the wand, and a valve bypass arrangement configured to selectively redirect air flowing through the body such that a majority of the air flowing through the body transitions between flowing through one of the wand coupling port and the nozzle coupling port. The valve bypass arrangement redirects the air in response to the wand being coupled to or decoupled from the wand receptacle.

摘要： 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.

摘要： A reconfigurable surface treatment apparatus may include a wand and a pod removably coupled to the wand. The wand may have a first distal end that is configured to couple to a surface cleaning head and a second distal end that is configured to couple to a handle. The pod may include a suction motor assembly cavity, a battery cavity, and a dust cup cavity. The suction motor assembly cavity and the battery cavity may be disposed on opposing sides of a vertical plane, wherein the vertical plane extends along a central longitudinal axis of the pod. The dust cup cavity may be disposed between the suction motor assembly cavity and the battery cavity such that at least a portion of the dust cup cavity is disposed on each side of the vertical plane.

摘要： An example of a surface cleaning head may include a main body, a neck pivotally coupled to the main body, a stabilizer, and a linkage pivotally coupled to the main body and the stabilizer. The linkage may be configured to cause the stabilizer to transition between an extended position and a retracted position in response to a pivotal movement of the neck.

摘要： An example of a vacuum pod may include a handle, a vacuum pod body, a dust cup removably coupled to the vacuum pod body, and a fluid conduit fluidly coupled to the dust cup. The fluid conduit may include a flexible hose configured to transition between an expanded and a retracted position and a coupling configured to be removably coupled to the vacuum pod body. A first end of the flexible hose may be coupled to the vacuum pod body and a second end of the flexible hose may be coupled to the coupling. When the coupling is coupled to the vacuum pod body, the flexible hose may be in the retracted position.
