A surface treatment machine, comprising a frame configured to translate with respect to a surface to treat, a surface treatment element connected to said frame and configured to treat with liquid a surface, a reservoir connected to the frame arranged to provide liquid to the surface treatment element through a delivery mouth; an adjustment element arranged to feed adjustably the liquid supplied from the reservoir to the delivery mouth. It is then provided a sensor configured to measure the speed of the frame with respect to the surface to treat. A control unit receives from the sensor a signal proportional to a speed for adjusting the adjustment element responsive to this value, in order to deliver the liquid with optimization of the flow-rate. It is possible then to maximize the range of the machine, and to optimize the working time of the operator.

A multi-use garbage truck has an ability to not only to front load containers of garbage into a hopper in a refuse collection body, but also an ability to swap out the forks, if not arm connection assemblies, or even entire frame arms, to be replaced with one of a plurality of attachments which connect to at least one, if not both frame arms with attachments for various uses such as snow plow, leaf blower, street sweeper, bucket, grapple, etc. Furthermore, an ability to independently operate the left frame arm relative to the right frame arm can now be provided so that the left frame arm can utilize and perform one function and the right frame arm provide another or at least be independently operable from one another.

A floor cleaner, comprising: a cleaning roller, a water channel, a clean water tank, a clean water supply system, a wastewater tank and an air pump. The water channel is configured to cover the cleaning roller with an airtight seal. The clean water tank, the clean water supply system and the water channel are in communication with each other, and the clean water supply system is configured to allow clean water in the clean water tank to flow to the water channel. The wastewater tank comprises a chamber for recovery and store of wastewater, and the chamber is provided with a wastewater inlet and an air extraction opening. The wastewater inlet and the water channel are in communication, and an inlet of the air pump and the air extraction opening of the wastewater tank are in communication.

A computer readable recording media recording at least one program. An automatic clean machine control method is performed if the program is executed, which comprises: (a) input a drawing or a picture to an automatic clean machine by a first user, wherein the automatic clean machine acquires a map based on the drawing or the picture; (b) directly selecting a region to be cleaned on the map; and (c) controlling the automatic clean machine to perform a first clean operation to the region to be cleaned based on the map.

A system and related apparatus and method for delivering fluid to and from a bottom center of a floor-operation pad on a rotary-motion flooring machine while the pad is rotationally operating on a horizontal underfoot surface, the system comprising a fluid-delivery hub comprising: a plurality of fluid entry openings disposed on an outside circumferential surface thereof; an equal plurality of fluid flow channels commencing at the fluid entry openings, angling downward and inward from the fluid entry openings toward a center of the fluid-delivery hub, and terminating at an equal plurality of fluid exit openings proximate a bottom center of the fluid-delivery hub; and a floor-operation interface at a bottom of the fluid-delivery hub configured to directly or indirectly attach a floor-operation pad thereto, for operating on a floor.

The invention relates to a cleaning device, in particular a floor-cleaning device, comprising a cleaning unit which is at least partly covered by an endless cleaning element that can be rotated continuously in relation to a surface to be cleaned during the action upon a surface to be cleaned. In order to devise a cleaning device in which regeneration of the endless cleaning element is particularly comfortable, the cleaning unit comprises at least one first roller part which can be placed on the surface to be cleaned and a second roller part, the radius of curvature of a roller subsection of the first roller part being different from a radius of curvature of a roller subsection of the second roller part.

A cleaner is disclosed. The cleaner includes a first cleaning module including a left spin mop and a right spin mop provided so as to come into contact with a floor while rotating in a clockwise direction or in a counterclockwise direction when viewed from an upper side, a second cleaning module configured so as to come into contact with the floor at a position spaced apart from the left spin mop and the right spin mop in a forward-and-backward direction, a body supported by the first cleaning module and the second cleaning module, and a water supply module configured to supply water to the first cleaning module and including a water tank disposed inside the body. Water supplied by the water supply module reaches the first cleaning module before reaching the floor.

A self-cleaning carpet system including a carpet base, a cleaning tube, a piston, a carpet fiber group, a water assembly and a vacuum assembly. The cleaning tube is mounted in the carpet base. The piston is operably mounted with respect to the cleaning tube for movement between a retracted position and an extended position. The carpet fiber group is attached to the piston. When the piston is in the retracted position, the carpet fiber group is substantially inside the cleaning tube. When the piston is in the extended position, at least a portion of the carpet fiber group extends from the cleaning tube. The water assembly is fluidly connected to the cleaning tube for delivering water to the cleaning tube. The vacuum assembly is fluidly connected to the cleaning tube for applying a vacuum to the cleaning tube.
