An automatically moving floor treatment appliance has a floor treatment element for acting on a surface to be treated, and a control device for controlling the floor treatment element. To increase the area of application of the floor treatment appliance, the control device is embodied to automatically control the floor treatment element as a function of a measuring result from an air parameter sensor in such a way that a floor treatment of the surface to be treated occurs using the floor treatment element and/or to automatically control the floor treatment element as a function of environmental data stored in an external storage device and relating to an air quality.

A cleaning system comprises a power plant, a regenerative blower having a power input shaft, a suction port, and a discharge port, an interface assembly configured for transmitting power from the power plant to the regenerative blower, a pump configured for generating pressurized water, and a heat exchanger system configured for heating the pressurized water.

A floor cleaning apparatus includes a chassis (138), a cleaning unit (50), and a least one suspension device (139). The cleaning unit (50) is mounted to the chassis (138) with at least one degree of freedom relative to the chassis (138) allowing the cleaning unit (50) to be lifted and lowered relative to the chassis (138). The at least one suspension device (139) is operatively active on the cleaning unit (50) and configured to transmit to the cleaning unit (50) an upwardly directed force.

A cleaning apparatus is provided, including at least one noise source and an air guidance device having at least one flow deflection element, wherein the at least one flow deflection element has a first duct arm and a second duct arm, wherein the second duct arm is oriented transversely to the first duct arm, and wherein, during operation of the cleaning apparatus, there is sound propagation from the first duct arm to the second duct arm, wherein a mode filter device for transverse modes of sound propagation is arranged at the at least one flow deflection element, having at least one mode filter that is positioned at the second duct arm.

The present disclosure relates to a mute operation method and a mute operation apparatus for an automatic cleaning device, the mute operation method includes: receiving a mute instruction; planning a mute cleaning path according to the mute instruction; switching to a mute mode and performing a cleaning operation according to the mute cleaning path.

A cleaning robot system includes a robot and a robot maintenance station. The robot includes a chassis, a drive system configured to maneuver the robot as directed by a controller, and a cleaning assembly including a cleaning assembly housing and a driven cleaning roller. The robot maintenance station includes a station housing and a docking platform configured to support the robot when docked. A mechanical agitator engages the roller of the robot with the robot docked. The agitator includes an agitator comb having multiple teeth configured to remove accumulated debris from the roller as the agitator comb and roller are moved relative to one another. The robot maintenance station includes a collection bin arranged to receive and hold debris removed by the mechanical agitator.

An autonomous robotic device capable of vacuum cleaning and purifying air includes an autonomous robotic vacuum cleaner for moving autonomously and vacuum cleaning, and an air purifier. The autonomous robotic vacuum cleaner has a power supply and a top surface provided with a plurality of positioning members. The air purifier has an air inlet, an air outlet, and a plurality of matching members at the bottom thereof. The air purifier is detachably disposed on the autonomous robotic vacuum cleaner in a way that the matching members are in contact with the positioning members to create a positioning relationship for positioning the air purifier on the autonomous robotic vacuum cleaner, and an electrical connection to enable the air purifier to receive electric power from the power supply of the autonomous robotic vacuum cleaner.

A cleaning system comprises a power plant, a regenerative blower having a power input shaft, a suction port, and a discharge port, an interface assembly configured for transmitting power from the power plant to the regenerative blower, a pump configured for generating pressurized water, and a heat exchanger system configured for heating the pressurized water.

An autonomous cleaning device, includes: a mobile platform, configured to move autonomously on a cleaning surface; and a cleaning module, disposed on the mobile platform and including a wet cleaning module, configured to clean at least part of the cleaning surface in a wet cleaning mode.

A surface cleaning apparatus includes an upright body and a base adapted for movement across a surface to be cleaned, a fluid delivery system, and a recovery system. The surface cleaning apparatus can be configured to clean multiple surfaces, including hard and soft surfaces, and for different cleaning modes, including wet cleaning, dry vacuum cleaning, and self-cleaning. Methods for self-cleaning a surface cleaning apparatus are also provided.
