A sweeping and mopping integrated household intelligent robot includes a host machine and a base station. Dust bins are arranged in the host machine. A mopping mechanism is arranged at the bottom of the host machine. A cleaning system and a dust collection system are arranged in the base station. The cleaning system is used for cleaning the mopping mechanism; and the dust collection system is used for recycling garbage in the dust bins. The sweeping and mopping integrated household intelligent robot of the present disclosure has excellent obstacle crossing capability, achieves a better mopping effect by virtue of rolling mops with double cloth-bundled rollers, provides a strong dust collection force and has a variety of optional work modes; the rolling mops of the host machine are automatically cleaned by the base station; and a base station dust bag can be replaced quickly and conveniently.

The present application provides a garbage collection system for a sweeping robot, including a base for placing the sweeping robot and a dust collecting box body connected to the base for collecting garbage in a sweeping robot storage box, an air duct is arranged in the base, and an inlet end of the air duct is aligned with the sweeping robot storage box; an inner chamber of the dust collecting box body comprises a transition chamber, a storage chamber and a power chamber, a blower is arranged in the power chamber, the power chamber communicates with the storage chamber, a dust filter element for filtering garbage is arranged in the storage chamber; a transmission channel is formed in the transition chamber.

An air purifying system includes a robot cleaner configured to generate map information during vacuum cleaning and at least one air purifier that is operated based on the generated map information. Air purifying is performed using updated map information acquired by the robot cleaner during cleaning. The at least one air purifier includes two portable air purifiers mounted on a base air purifier. The two portable air purifiers are configured to be lifted from the base air purifier and moved to separate indoor rooms. The base air purifier includes a controller that determines, based on the generated map information and other information, which rooms the two portable air purifiers should be placed in so that air purifying may be efficient.

A cover is provided for a robotic floor cleaner to enclose the cleaner when the cleaner is docked in a charging station. The cover is shaped complimentarily to the shape of the robotic floor cleaner. The cover includes a flat, smooth, horizontal top and a circular sidewall with an open front mouth to through which the robotic floor cleaner moves into and out of the charging station. The cover may have a rear notch to accommodate structure on the charging station. The cover has sufficient strength to support a plant or decorative object on the top.

A floor cleaning and polishing device has a polishing pad for a surface which is rotationally engaged upon a pad driver operatively engaged to a frame. A first set of wheels on the frame allow for tilted movement. A second set of wheels are positionable to a deployed position to elevate the first set of wheels from the surface and position the polishing pad parallel to the surface. The device may have a light projector engageable for light disinfecting. The polishing pads are configured with a plurality of polishing fabric sections separated by recesses therebetween.

Disclosed is a drainage system for an automatic cleaning storage base of an electric mop. The automatic cleaning storage base of the electric mop comprises a casing member having a cleaning tank. The drainage system comprises a drain valve; an outlet end of the drain valve is connected to the outside of the casing member, and an inlet end of the drain valve is connected to the cleaning tank; the drain valve has a switch, and the switch is provided with a first rack; the drain valve is further provided with a duplex gear and a second rack; the duplex gear has a gear portion with a larger outer diameter to mesh with the first rack, and the duplex gear has a gear portion with a smaller outer diameter to mesh with the second rack.

A trolley and method for loading and unloading cleaning robots into a trolley, including for storing, emptying and supplying energy to cleaning robots. The trolley includes an energy supply unit, storage compartments, each storage compartment having a charging contact which is designed to be contacted with a cleaning robot arranged in the corresponding storage compartment to supply the cleaning robot with energy, transport wheels configured to move the trolley over a substrate, a suction system having a foldable suction platform configured to empty one of the cleaning robots arranged on the suction platform, a lift system with a foldable receiving element configured to transport the cleaning robots individually by way of the receiving element in its unfolded state to the storage compartments and away from the storage compartments, and at least one door element configured to close or expose the foldable receiving element and the foldable suction platform.

A method for bringing cleaning robots into and out of a trolley, and cleaning system, in which each cleaning robot is automatically brought into the trolley individually and the cleaning robots are automatically brought out of the trolley in an order depending on the cleaning effort assigned to them or in a sequence specified by a user of the trolley. A cleaning system comprises a trolley and a multiplicity of cleaning robots configured to carry out the method.

A cleaning base station including a cleaning body, a sewage collecting body, and a draining structure is provided. The cleaning body is defined with a filtering hole, and the sewage collecting body is connected with the cleaning body to collect sewage flowing out from the filtering hole. The draining structure is detachably connected with the sewage collecting body. The sewage collecting body can be disassembled from the draining structure to be cleaned since the draining structure and the sewage collecting body are detachably connected, which is very convenient.
