摘要： A surface cleaner that includes an accessory body removably coupled to a base. A nozzle has a first nozzle portion having a first nozzle passageway attached to the base and a second nozzle portion having a second nozzle passageway attached to the accessory body and removable with the accessory body. The first nozzle portion and second nozzle portion are releasably coupled connecting the first and second nozzle passageways along an airpath in fluid communication with a collection container when the accessory body is coupled to the base. The first nozzle passageway forms a suction inlet when the accessory body is coupled to the base and the second nozzle passageway forms the suction inlet in communication with the collection container and the suction source when the accessory body is uncoupled from the base.

摘要： An automatic cleaning device includes a mobile platform, a lifting station, a cleaning module, a liquid supplying module, and a collecting module. The mobile platform is configured to automatically move in a target direction on a surface to be cleaned. The lifting station is connected to the mobile platform and configured to move upwards or downwards with respect to the mobile platform. The cleaning module is connected to the lifting station and configured to clean the surface to be cleaned; the liquid supplying module is configured to provide cleaning liquid to the surface to be cleaned; and the collecting module is configured to collect the cleaning liquid. A height of the cleaning module of the automatic cleaning device is adjustable, and the automatic cleaning device has a great cleaning strength and is capable of collecting dirty cleaning liquid, thus, the automatic cleaning device can be applied broadly.

摘要： In exemplary embodiments of the present invention, various novel dispensing devices can be provided. Such devices can involve a range of sprayer heads and sprayer/foamer systems incorporating such heads. Novel sprayer/foamer heads can include buffers of various types. By using a buffer, a user need not continually be pumping the device in order for the device to be spraying or foaming. In exemplary embodiments of the present invention, such a buffer can be spring loaded, spring loaded combination, elastomeric or gas. In exemplary embodiments of the present invention, the buffer can be in line or adjacent to a piston chamber. If adjacent, it can be connected to the piston chamber with a one way valve, to provide for spray after a downstroke of the piston has been completed, or without, to allow spraying to cease once a user releases the trigger or other actuator. In exemplary embodiments of the present invention, such novel sprayers and foamers can be mounted upside down, in various “Flairomop” devices, used to clean floors or the like. When using a buffer, a piston chamber can be designed to deliver greater amount of liquid per unit time than can be possibly dispensed through the nozzle or nozzles. The fraction of liquid that cannot be sent through the nozzle(s), due to their inherent restriction, can thus be sent to the buffer for dispensing after the piston downstroke has been completed. A volume of the piston chamber, a volume of the buffer, a pressure response of the buffer, the throughput of the nozzle, and the minimum opening pressure of the outlet valve can be arranged to restrict the outlet pressures of liquid droplets exiting the nozzle within a defined range.

摘要： A floor scrubber cleaning system includes a combustion engine powered floor scrubber using at least one rotating scrubbing brush/pad. A tank or reservoir is used for supplying a cleaning solution to the scrubbing brush/pad for cleaning a floor. A heat exchanger uses coolant from the combustion engine to heat the cleaning solution where it is dispensed directly onto the floor.
