A cleaning device and methods for cleaning are provided. In one embodiment, the cleaning device includes a head assembly, a body assembly, and a handle assembly. The cleaning device also includes components that enable the cleaning device to operate in dry cleaning modes and wet cleaning modes. Dry cleaning modes can employ a vacuum assembly, including a motor, tubing, and a fluid recovery tank in order to draw in debris and waste into a fluid recovery tank. Wet cleaning modes can further employ a fluid supply tank, a pump, and tubing in order to supply fluid to a brushroll to aid in a cleaning process.

A vacuum cleaner including a cleaner body including a motor configured to generate a suction force and a foreign substance collection chamber; and a suction head connected to the cleaner body. The suction head may include a drum brush, a one-way roller disposed in front of the drum brush, and a housing having a suction port. The drum brush and the one-way roller may be configured so that, when the suction head is moving forward on a surface to be cleaned, the drum brush and the one-way roller rotate so that foreign substances on the surface are suctioned by the suction force into the housing through the suction port to be guided to the foreign substance collection chamber, and when the suction head is moving rearward on the surface, rotation of the one-way roller is restricted to prevent the foreign substances suctioned into the housing from being discharged outside of the housing of the suction head through the suction port.

A cleaner includes a main body and a suction head connected to the main body to suck foreign objects into the main body therethrough, the suction head including a housing including a suction port, and a drum module disposed in the housing, and to be rotated to scatter the foreign objects to be sucked through the suction port so that the scattered foreign objects are drawn into the housing through the suction port, and the drum module including a drum body, a first blade coupled to outer circumference of the drum body, a second blade separated from the first blade in a circumferential direction of the drum body and having a mass greater than a mass of the first blade, and a mass compensation member arranged on the outer circumference of the drum body to compensate for a difference in mass between the first blade and the second blade.

A surface cleaning apparatus has a suction motor actuator that is actuatable to actuate the suction motor to operate in a first mode of operation and to operate in a second mode of operation, the first mode of operation defining a first discrete power level for the suction motor and the second mode of operation defining a second discrete power level for the suction motor. The first mode of operation is enabled when the first power pack having a first level of power is provided to power the surface cleaning apparatus and the second mode of operation is not enabled until a second power pack is provided such that the surface cleaning apparatus has a second level of on board power that is greater than the first level of on board power.

Embodiments of the present disclosure provide a self-cleaning control method of a cleaning device, a cleaning device, and a storage medium. The cleaning device is provided with at least one self-cleaning object. The control method includes: determining a current self-cleaning mode of the cleaning device according to a predetermined condition; and controlling the cleaning device to clean the self-cleaning object according to the determined current self-cleaning mode. Based on technical solutions in the embodiments of the present disclosure, different self-cleaning modes can be selected according to different dirt conditions of the cleaning device, thereby improving the selection flexibility of a self-cleaning mode of the cleaning device.

An electric cleaning device includes a housing, a cleaning roller and a driving assembly. The housing includes a cleaning chamber and the cleaning chamber defines an opening at bottom. The cleaning roller is arranged at the opening and defines a first accommodating space. The driving assembly is arranged in the first accommodating space and configured to drive the cleaning roller to rotate.

An autonomous traveling floor cleaner is disclosed that improves cleaning efficiency. A floor cleaner may include a suction nozzle that suctions suction matter collected by a rotary brush, an extension nozzle that suctions suction matter collected by an extension brush, and a collection box for collecting, through an inlet, the suction matter suctioned by the nozzles. The floor cleaner may have an elongated profile. The extension nozzle may be switchable between a retracted posture and a lateral cleaning posture. The extension nozzle in the lateral cleaning posture may be pivotable rearward. The extension nozzle in the lateral cleaning posture may have a protruding end in the width direction to be aligned with an end of a turning range of the floor cleaner in the width direction.

A removable rotatable driven agitator is used in a surface cleaning head and is driven by a drive mechanism that axially engages a driven end of the agitator. The removable rotatable driven agitator may be located in an openable agitator chamber for purposes of removing debris and/or removing the agitator. The openable agitator chamber may be covered by an external cover that is movable between an open position and a closed position. The removable agitator may be secured in the agitator chamber by the external cover. The removable rotatable agitator may have an end cap mounted on a rotatable bushing at a non-driven end and may have a splined driven member at the driven end to engage a splined drive member on the drive mechanism.

An apparatus for cleaning a floor surface including a control unit, a cleaning member for picking up dirt from the floor surface by moving the cleaning member, and an electric motor for moving the cleaning member. The electric motor is such that relative movement between a stator and a rotor of the electric motor can lead to an induction of a voltage and a reverse current. The control unit is configured such that a power supply of the electric motor is temporarily interrupted during a cleaning operation of the floor surface, and the control unit identifies a present surface condition of the floor surface currently being cleaned by means of the cleaning member on the basis of a detected current curve of the electric motor.
