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.

An embodiment of the present disclosure provides a cleaning robot and a control method thereof. The cleaning robot includes: a chassis; a fluid applicator, carried on the chassis and configured to distribute a cleaning fluid on at least part of a cleaning width; a fluid storage apparatus, detachably connected to the chassis, wherein the fluid storage apparatus is in communication with the fluid applicator and configured to apply the cleaning fluid distributed by the fluid applicator to a floor; and a control unit, carried on the chassis and configured to control the fluid applicator to stop distributing the cleaning fluid in a case that a to-be-cleaned area of the floor reaches a preset value.

Provided are a cleaning machine, a cleaning device, an information display method thereof, and a storage medium. A display is additionally arranged on a main body of the cleaning machine to display working state information of at least one component on the cleaning machine, thereby visually displaying a working state of the cleaning machine. A user may know about a working state of a component on the cleaning machine visually, which contributes to improving user experiences.

A floor cleaner includes a recovery tank including an inflow path allowing liquid-laden air to enter the recovery tank, an outflow path allowing air to exit the recovery tank; and a chamber for storing liquid. The chamber includes an inlet, a separator that separates liquid from the liquid-laden air, an air outlet, and a float. The float includes a base and a valve with an indicator. The float is moveable between a first position and a second position. In the first position the valve is spaced away from the air outlet and air is allowed to exit the chamber. In the second position the valve is adjacent the outlet and impedes air from exiting the chamber. In the second position the indicator is visible when the chamber is full.

The present specification relates to a mobile robot and a control method therefore, in which the mobile robot generates virtual floor surface information about a travelling environment by accumulating, for a certain time, the results of sensing via a camera sensor to improve the accuracy of obstacle detection using the camera sensor, detects whether or not there is an obstacle in the travelling environment, on the basis of the floor surface information, and controls travel according to the result of the detection.

The invention relates to a cleaning system, comprising a cleaning cart and an external accessory device, wherein the cleaning cart comprises a frame having rollers for moving on a ground surface, at least one receptacle for receiving and/or carrying cleaning utensils, and an interaction device having a hand-actuatable interaction element, wherein the accessory device is portably configured and a user application program for processing cleaning-related information is executably stored on the accessory device and/or operable via the accessory device, wherein the interaction device and the accessory device are coupleable with one another via a communication connection, and wherein, depending on an actuation of the interaction element by the user, input information for operation of the user application program is transmittable from the interaction device to the accessory device and is processable by the accessory device. The invention further relates to a method for operating a cleaning system.

Multiple floor treatment operations, such as burnishing, polishing and scrubbing, may be performed using a single floor treatment machine having a motor, the speed of which is governed by a controller that responses to sensor signals indicative of the type of floor treatments pad or pads operatively coupled to the motor.

A cleaning device includes a cleaning device body and a replacement head. The cleaning device body includes an elongated handle, a housing and a replacement head mounting section. The replacement head has a pad that is intended to clean a surface, such as a floor and is removably attachable to the cleaning device body. The housing includes a circuit board having at least one sensor capable of sensing motion. The handle includes at least one button that can turn on/off either a vacuum source or a jet nozzle that sprays cleaner fluid. The cleaning device body further includes at least one light mounted thereon. The at least one light is illuminated when the button is pressed and then the at least one light remains illuminated until a predetermined amount of time has passed during which neither the button has not been pressed nor motion sensed by the sensor.

The present disclosure relates to a robotic cleaner. The robotic cleaner may be configured such that an imaginary plane passing mop contact portions having a small area passes through the center of gravity of the robotic cleaner, thereby travelling while the mops effectively scrub a floor surface.

A cleaning device designed to clean a surface includes a cleaner nozzle to face the surface to be cleaned and to perform a cleaning action on the surface, where the cleaner nozzle accommodates at least one rotatably arranged brush including flexible brush elements having tip portions which are intended to contact the surface. The cleaning device includes a force-actuable mechanism that is responsive to a change of a user force on the cleaning device acting to press the cleaner nozzle against the surface when the cleaner nozzle is in an operational position on the surface, and that is functional to cause a change of a value of at least one parameter of operation of the cleaning device, thereby enabling more intuitive handling of the cleaning device by a user.
