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.

A cleaning system includes a cleaning vehicle that cleans a predetermined travel route, a maintenance facility provided at a specified position on the travel route and performs maintenance on the cleaning vehicle, and a control device that controls them. The control device executes interruption and maintenance control in response to a state of the cleaning vehicle satisfying a predetermined maintenance condition during execution of the cleaning by the cleaning vehicle. The interruption and maintenance control includes first control for interrupting the cleaning performed by the cleaning vehicle, causing the cleaning vehicle to move to the specified position, and causing the maintenance facility to perform the maintenance on the cleaning vehicle, and second control for causing, after the first control, the cleaning vehicle to move to an interruption position at which the cleaning was interrupted, and causing the cleaning vehicle to resume the cleaning from the interruption position.

The present disclosure relates to the field of cleaning robot technology, and in particular to a cleaning robot system. The cleaning robot system includes a base station and a cleaning robot. The base station is independent to the cleaning robot of the cleaning robot system. The base station includes a base station body and a mop member cleaning device arranged on the base station body. The mop member cleaning device is configured to clean a mop member of the cleaning robot. Based on the base station, the cleaning robot system is capable of automatically cleaning the mop member with no need for users to change or clean the mop member frequently, which is helpful to free consumers from house cleaning, thus relieving the burden on the consumers, and also helpful to clean the mop member in time so as to ensure a better effect in next cleaning.

A reservoir device includes: a liquid storage structure, configured to store liquid; a liquid feeding assembly, configured to feed the liquid into the liquid storage structure; a barrier assembly; a sensing field generator, configured to generate a sensing field; a sensor; and an electrical control assembly. The barrier assembly is arranged inside the liquid storage structure. The sensor is configured to sense the sensing field. The barrier assembly is configured to float under a buoyance action of the liquid, and to block the sensor from sensing the sensing field when the barrier assembly floats in a first liquid level position. The electrical control assembly is configured to control the liquid feeding assembly to stop feeding the liquid into the liquid storage structure when the barrier assembly blocks the sensor from sensing the sensing field.

A floor cleaning machine with a filter unit for a suction connector in a dirty-water tank. The filter unit has a substantially sleeve-shaped main body, which has an inlet opening at a face end, a substantially annular float body, which is arranged around and is displaceable along the main body between a closed position and an open position, a cover, which is arranged on the face end and has an entry opening that is configured to be selectively closed off by the float body. A fluid channel is provided in the cover and is configured to allow a fluid to flow from the entry opening into the inlet opening, and a sleeve-shaped filter element. The float body is arranged around the main body in an annular space between the main body and the filter element.

An autonomous floor cleaner can include a housing, a drive system for autonomously moving the housing over the surface to be cleaned, a controller for controlling the operation of the autonomous floor cleaner, and warning system for issuing a warning based on the detection of moisture inside the robot. Methods for issuing a warning are disclosed.

The present invention relates to the field of floor treatment machines which involve wet treatment of a floor or carpet in which dirty liquid is collected by suction. In one aspect there is provided a float valve assembly for a collection tank in a suction liquid collection device, the assembly comprising: a float constrained in an enclosure which is configured to permit the float to rise in response to a rising liquid level, a closure feature disposed above the float and connected thereto so that as the float rises the closure feature rises from an initial position, wherein a suction port is disposed in the tank vertically spaced apart from the initial position of the closure feature, the suction port being in fluid communication with a suction drive which in use draws air-entrained liquid into the collection tank, the arrangement being such that as liquid fills the tank the liquid acts upon the float to cause the closure feature to travel towards the suction port, and when the closure feature rises sufficiently, the closure feature obturates the suction port, thereby closing the suction port and preventing further air-entrained liquid from entering. The closure feature may be connected to the float by a plunger which is disposed above the float so that the float shunts the plunger to travel in an upwards direction as the float rises.

The present disclosure provides cleaning robot, including a cleaning agent mopping device (1), a cleaning agent absorbing device (2), a water wiping (3) and washing device (4), and a water absorbing device arranged in turn along a moving direction of the cleaning robot. Each time when the cleaning robot of the present disclosure works to clean the to-be-cleaned surface, the cleaning robot can perform the four steps including cleaning agent mopping, cleaning agent absorbing, water wiping and washing, and water absorbing, thus, both hydrolysable and non-hydrolysable stains can be effectively cleaned by the cleaning robot. Thus, the cleaning robot is very practical, easy to operate, and simple to use.

Cleaning equipment includesa water divider structure comprisinga pressuresource connected to a water supply tank, a water divider provided with a first distribution channel and a second distribution channel, wherein the first and second distribution channels both are connected with the pressuresource, anda first unidirectional valve connecting between the pressuresource and the water divider, wherein the first unidirectional valve connects through the pressuresource and the water divider under pressure formed when the pressuresource is activated. When there is residual water in the pipeline between the first unidirectional valve and the water divider structure, the first unidirectionalvalve can prevent the water in the water supply tank from being transported downstream. At this time, there is water in the pipeline downstream of the first unidirectionalvalve. One end is closed, and one end of the water divider structure is connected to the outside.
