A system for coupling a container storing a treating chemistry to a surface cleaning device capable of dispensing the treating chemistry to a surface to be cleaned includes a cap provided on the container and a receiver provided on the surface cleaning apparatus. The cap and receiver include plunger valve assemblies that are opened when the cap is coupled with the receiver.

A machine for cleaning and sanitizing contains an outlet, a flow selector, a hydraulic circuit, a pump, a first three-way hydraulic fitting, a detergent injector, a second three-way fitting, at least one air compressor, and a fourth three-way fitting. The hydraulic circuit contains a first branch, a second branch, and a third branch. The outlet of the machine is adapted to mount a foam or rinse water dispenser, which is adapted to emit foam from the first branch or water from the second branch. The air compressor is in flow communication with the third branch. The flow selector is adapted to divert either the foam from the first branch or the water from the second branch towards the outlet of the machine.

A cleaning robot includes a dust suction assembly including a roller brush assembly, a cavity body, a first blocking member located on a front side and a second blocking member located on a rear side of the roller brush assembly. The roller brush assembly includes a first roller brush and a second roller brush that are longitudinally arranged. Each of the first blocking member and the second blocking member has a free end close to a bottom surface of the dust suction assembly; a distance between the free end of the first blocking member and the bottom surface is a first distance, and a distance between the free end of the second blocking member and the bottom surface is a second distance, both the first distance and the second distance is greater than or equal to 0 and less than 5 mm.

A floor cleaning and drying system for simultaneously shampooing, vacuuming, and drying a floor includes a housing. A power source is coupled to the housing. A shampooing apparatus is coupled to the housing and expels a cleaning fluid under pressure downwardly onto a floor. A vacuum apparatus is coupled to the housing and suctions a dirty fluid upwardly from the floor. A floor drying apparatus is coupled to the housing and blows a heated gas downwardly onto the floor to facilitate drying the floor. A plurality of wheels is rotatably coupled to the base wall to facilitate movement of the housing across the floor. A handle extends upwardly from the housing. A control panel coupled to the handle is electrically coupled to the power source for selectively actuating the shampooing apparatus, the vacuum apparatus, and the floor drying apparatus.

The disclosure provides a cleaning device, including a machine body, a fluid recovery system, a floor brush, an accessory and a first control valve component. The fluid recovery system includes a fluid recovery container and a suction pipe. The floor brush includes a suction port, the suction port is configured for being in fluid communication with the fluid recovery system, and the floor brush is connected with the machine body. The accessory includes a dirt suction pipe, the dirt suction pipe is configured for being in fluid communication with the fluid recovery system, and the user is able to hold the accessory to suck dirt. The first control valve component is arranged among the suction pipe, the suction port and the dirt suction pipe, and the first control valve component is configured to control the suction pipe to be selectively communicated with the suction port or the dirt suction pipe.
