A floor nozzle for a vacuum cleaner has a housing, and a base on the housing constructed for sliding in a working direction on a floor and formed with a downwardly open slot-shaped port delimited relative to the direction between a transversely extending front port edge and a transversely extending rear port edge. The base has, extending forward from the front port edge, a part-cylindrical and downwardly convex front surface with a front radius of curvature and centered on a transversely extending symmetry axis and, extending rearward from the rear port edge, a part-cylindrical and downwardly convex rear surface having a rear radius of curvature also centered on the symmetry axis. The housing is constructed for movement of air upward through the port.

The present disclosure relates to a cleaner system including: a cleaner; a cleaner station; and an imaginary plane including an imaginary suction flow path through line penetrating a suction flow path in a longitudinal direction and an imaginary suction motor axis defined by extending a rotation axis of a suction motor, in which when the cleaner is coupled to the cleaner station, the plane penetrates at least a part of the cleaner station, such that a center of gravity of the cleaner is disposed to pass through a space for maintaining balance of the station, and as a result, it is possible to stably support the cleaner and the station while preventing the cleaner and the station from falling down.

A handheld air purifier may include a suction body provided with a fan to suction air and a filter to filter foreign matter from the sucked air, a handle extending from the suction body, and an agitator provided in the suction body to loosen or scatter dust from a garment. The handheld air purifier may be configured to be attached to and detached from a main air purifier, and the main air purifier may suction dust off the handheld air purifier and sterilize the handheld air purifier when the handheld air purifier is mounted on the main air purifier. The agitator of the handheld air purifier may have a striking member exposed through a lower surface of the suction body, and may move out of and into the suction body to strike the garment so that the dust may be loosened and suctioned into the suction body and filtered by the filter.

A surface treatment apparatus may include a coupling, a handle, an accessory coupled to the coupling, and a toggle proximate the handle. The accessory may have at least two operational states. An actuation of the toggle may cause the accessory to transition between operational states.

A station and a dust removal system including the same are provided. The station according to one aspect of the present specification is a station to which a cleaner including a dust bin and a body cover selectively opening and closing a lower part of the dust bin is coupled, including a coupling body to which the dust bin is coupled and forms a predetermined angle with a ground; a separating unit which separates the body cover from the dust bin; and a dust storage unit which is disposed under the coupling body, the predetermined angle being between 20 degrees and 30 degrees, and the dust bin being slid by gravity and coupled to the coupling body.

The present disclosure provides a cleaning robot, a cleaning module, a cleaning assembly, a base and a cleaning system, wherein the cleaning robot includes: a robot apparatus, configured to carry the cleaning module; and a first replacement mechanism, configured to enable the robot apparatus to be loaded with the cleaning module, and replace a cleaning module carried on the robot apparatus with the loaded cleaning module. When the cleaning robot is loaded with a new cleaning module, the loaded new cleaning module replaces the old cleaning module originally carried on the cleaning robot, in this way, the assembling and disassembling of the cleaning modules on the cleaning robot can be performed synchronously.

A robotic cleaning system may include a robotic cleaner having a robotic cleaner dust cup and a docking station having a docking station dust cup configured to fluidly couple to the robotic cleaner dust cup. The docking station dust cup may include a first debris collection chamber, a second debris collection chamber fluidly coupled to the first debris collection chamber, and a filter fluidly coupled to the first debris collection chamber and the second debris collection chamber.

A cleaning apparatus including a vacuum cleaner and a docking station is provided. The cleaning apparatus includes a vacuum cleaner including a dust collecting chamber in which foreign substances are collected, and a docking station configured to be connected to the dust collecting chamber to remove the foreign substances collected in the dust collecting chamber. The dust collecting chamber is configured to collect foreign substances through centrifugation, and configured to be docked to the docking station, and the docking station includes a suction device configured to suction the foreign substances and air in the dust collecting chamber docked to the docking station.

A cleaning tray is provided for docking an extraction cleaner, including upright or robot extraction cleaners, for self-cleaning. The cleaning tray may include one or more sprayers for spraying a cleaning fluid toward a suction nozzle, brush chamber, and/or agitator of the extraction cleaner. Systems for self-cleaning extraction cleaners are also provided.

A surface cleaning apparatus includes a base assembly with a suction nozzle and at least one wheel. A hand-held portion has a hand grip, a recovery container, and a suction source in fluid communication with the suction nozzle and the recovery container and configured for generating a working airstream. A wand is operably coupled between the base assembly and the hand-held portion and defines at least a portion of a working air path extending from the suction nozzle to an air outlet in the hand-held portion and including the suction source.
