Systems and methods include a high dump hopper system wherein a debris hopper can be split into two hoppers for positioning adjacent a wheel of the floor cleaning machine. The hoppers, split or not, can be located near the front of the machine such that the overall length of the floor cleaning machine need not be extended. A splitter can be positioned proximate the floor cleaning mechanism to drive debris into the split hoppers. The hoppers, split or not, can be coupled to a common lifting system that can pull the hoppers out from under a chassis of the floor cleaning machine and then upwards for positioning relative to a refuse container. Furthermore, the orientation of the hoppers can be controlled to position openings for the hoppers in a desired location to prevent spilling and facilitate emptying.

Method for operating a dirt collecting device for a sweeping vehicle or for a vacuum cleaner nozzle of a floor or upright vacuum cleaner, which each comprise a suction fan with controllable speed and/or power, wherein in a first method step, the suction power of the suction fan is set at such a low level that the suction pressure in the dirt collecting device or the vacuum cleaner nozzle is merely sufficient to convey and deposit the absorbed coarse dirt into the intermediate container, and to convey the absorbed fine dirt into a downstream collection container, (normal operation); and that in a second method step, the filling level in the intermediate container is detected with respect to the coarse dirt deposited therein; and that in a third method step, if the filling level in the intermediate container is exceeded, the suction power of the suction fan is increased such that the coarse dirt, which is temporarily deposited in the intermediate container, becomes dispersible and is conveyed into the downstream collection container (emptying mode).

A floor cleaning machine having an intelligent system including a recovery tank sub-assembly, a vacuum fan sub-assembly, a solution tank sub-assembly, wherein the solution tank sub-assembly preferably includes a secondary electrochemical cell, a solution flow sub-assembly, a control console sub-assembly, a frame and wheel sub-assembly and/or a frame and transaxle sub-assembly, a scrub head sub-assembly, a scrub head lift sub-assembly, a squeegee sub-assembly, a solution flow sub-assembly, and an intelligent system associated with at least one of the above-identified sub-assemblies, wherein the intelligent system at least one of selectively gathers, obtains, monitors, stores, records, and analyzes data associated with components of the floor cleaning machine assembly, and at least one of controllably communicates and disseminates such data with at least one of another system and user.

A cleaning robot includes a navigator to move a main body, a remote controller to output a modulated infrared ray in accordance with a control command of a user and to form a light spot, a light receiver to receive the infrared ray from the remote controller, and a controller to control the navigator such that the main body tracks the light spot when the modulated infrared ray is received in accordance with the control command. Because the cleaning robot tracks a position indicated by the remote controller, a user may conveniently move the cleaning robot.

A robot cleaner comprising: a cleaner body including a controller, the cleaner body having a dust container accommodation part formed therein; a wheel unit mounted in the cleaner body, the wheel unit of which driving is controlled by the controller; and a dust container detachably coupled to the dust container accommodation part, wherein a first opening and a second opening are disposed at the same height in an inner wall of the dust container accommodation part, wherein the dust container includes: an entrance and an exit, disposed side by side along the circumference of the dust container, the entrance and the exit, respectively communicating with the first opening and the second opening when the dust container is accommodated in the dust container accommodation part; and a flow separating part extending downwardly inclined along the inner circumference of the dust container.

A cleaning robot includes a top cover, a bottom cover formed below the top cover and configured to move by external force, a fixed body provided in the bottom cover, a first opening formed in an upper portion of the bottom cover and a first sensor connected to the fixed body and externally exposed between the top cover and the bottom cover through the first opening.

The present disclosure provides a surface cleaning apparatus that includes steam delivery. The apparatus includes a hand-carried body adapted to be hand carried by a user, the hand-carried body having a main housing, a supply tank, and a heater. A flexible hose is mounted to the hand-carried body and a hand-held cleaning tool mounted to an end of the hose. The tool has a liquid distributor to deliver liquid cleaning fluid and a steam distributor to deliver steam. Various features for controlling the operation of electrical component of the extraction cleaner are disclosed.

A mobile cleaner includes a body, a mop module, and a sweep module. The mop module includes a pair of spin mops configured to rotate and mop a surface. The sweep module is configured to sweep up foreign material on the surface using a rotating agitator. The sweep module includes a dust housing, the agitator, and a wheel assembly. The wheel assembly is configured to support the dust housing on the surface and includes a wheel body that is movable in a vertical direction. A cliff sensor is configured to detect movement of the wheel body.

The cleaning robot includes a housing, a brush roller and a suction device. The housing is provided with a mounting chamber. A debris collecting chamber is communicated with the mounting chamber. The brush roller is pivotally mounted in the mounting chamber and at least a part of the brush roller protrudes from the mounting chamber. The housing is further provided with a debris collecting channel, one end of the debris collecting channel is communicated with the debris collecting chamber, the other end of the debris collecting channel penetrates through the rear end of housing, and the housing is further provided with a first door for opening or closing the debris collecting channel.

A cleaning apparatus may include: a main-body unit; and first and second dust units, which are alternately attachable to and detachable from the main-body unit. The main-body unit may include: one or more cleaning tools, which brush(es) up waste on a work surface; a main body rotatably supporting the cleaning tool(s); and one or more wheels rotatably supported by the main body and configured such that the cleaning apparatus is movable along the work surface via the one or more wheels. The first dust unit may include: a first container, which is detachable from the main body and is capable of collecting the waste brushed up by the cleaning tool(s). The second dust unit may include: an adapter, which is detachable from the main body; and a second container, which is detachable from the adapter and is capable of collecting the waste brushed up by the cleaning tool(s).
