A hose reel unit for a high-pressure washer has a hose reel and a reel hose arranged in its receptacle. The hose reel is rotatable about an axis of rotation for winding and unwinding the reel hose. The first end of the reel hose is connectable to a supply line and the second end to a washer wand of the high-pressure washer. The hose reel has sidewalls delimiting the receptacle in a direction of the axis of rotation. The first end of the reel hose extends to the first sidewall and is coaxial to the axis of rotation. A guide device arranged between the sidewalls guides the reel hose such that the axis of rotation extends through the reel hose. The guide device is spaced apart form the first end of the reel hose at a support distance measured in a direction of the axis of rotation.

A touchless cleaning assembly for cleaning a room in a touch-less manner includes a cabinet is recessed into a wall of a room. A plurality of hose reels is positioned in the cabinet and each of the hose reels includes a hose that is drawable outwardly from the cabinet for spraying a fluid for cleaning surfaces in the room, for blowing air to dry the surfaces and to vacuum the surfaces. An air compressor is positioned within the cabinet to direct compressed air into a respective hose reel to dry the surfaces. A vacuum is positioned within the cabinet to supply vacuum pressure to the a respective hose reel for suctionally removing the fluid from a floor of the room.

The present invention provides a pump for supplying a liquid. The pump comprises: a tube member having a hose communicating with a chemical liquid inlet and a chemical liquid outlet, and a cylindrical drum provided to wind the hose, and configured to discharge a chemical liquid through a volume change caused by contraction of the hose wound around the drum; and a driver configured to provide a rotational force such that the hose is wound around the drum.

An electric pressure washer includes an electric motor operably connected to a pump, one or more removable detergent tanks, a removable accessory bucket in which a spray gun, high pressure hose, and other accessories may be stored, and a foot pedal for facilitating operator control of one or more features of the electric pressure washer during use. The electric pressure washer may also include a folding handle for facilitating storage and transport.

Disclosed is a two-in-one cleaning apparatus. The two-in-one cleaning apparatus includes a positioning assembly, a booster pump, an automatic hose reel, an intermediate connecting rod, and a spray gun body. The booster pump, the automatic hose reel, the intermediate connecting rod, and the spray gun body are all detachably mounted on the positioning assembly. The booster pump is provided with a water inlet and a water outlet, a water inlet pipe is arranged at the water inlet of the booster pump, and the water outlet of the booster pump is connected to the automatic hose reel. The automatic hose reel is provided with a mounting bracket, the positioning assembly is provided with a positioning support plate matching the mounting bracket, and the automatic hose reel is mounted on the positioning assembly through matching between the mounting bracket and the positioning support plate. The spray gun body is detachably connected to the booster pump and the intermediate connecting rod, respectively. The disclosure has the beneficial effects of being convenient to carry, high in stability, wide in application range, capable of meeting different use requirements, convenient to dismount and mount, simple in structure and convenient to operate.

A pressure assisted washer or pressure washer with hose reel and motor pump assembly. The hose reel defines a bore in which a motor pump assembly is disposed. The hose reel comprises a cylinder having an aperture through which pressurized fluid can be accessed through a coupling in fluid communication with a pump. The pump has a rotating collar.

An underwater cavitation jet cleaning system provided with an automatic metering feeder for cleaning solution organically integrates a cavitation jet technology with the improvement of cleaning solutions, which can not only increase bubbles can be during jet, but also is beneficial for removing hull dirt. An eddy segment of a nozzle is arranged as a spiral passage, and the eddy segment is gradually reduced from a water inlet to a water outlet, so that a speed of fluid becomes further faster. A volume of an in-pipe chamber of a barrel is different, and the fluid is pulsed while flowing through the barrel, so that the fluid is finally ejected from the nozzle of a cleaning gun, which efficiently improves the cavitation rate, and increases the generation of cavitation nucleus.

A system includes a frame, a spot-free water generator, a booster pump, a tank, a first pressure washer, and a first on-demand pump. The frame is configured to be received within and coupled to a portion of an interior of a vehicle. The spot-free water generator includes a carbon filter, a pre-filter, and a plurality of membranes and is configured to generate spot-free rinse water from tap water. The booster pump receives tap water from an exterior water inlet port and delivers the tap water to the spot-free water generator at a predetermined pressure. The tank is coupled to the frame and receives and stores at least a portion of the spot-free rinse water generated by the spot-free water generator. The first on-demand pump is coupled to the frame and is configured to deliver spot-free rinse water from the tank to the first pressure washer.

A heatable high pressure cleaning appliance is provided with an undercarriage and a housing lower part, arranged on the undercarriage, in which a motor and a pump driven by the motor for pressurizing water are arranged, and with a fuel-operated heat exchanger for heating the water and a fuel tank for storing liquid fuel for the heat exchanger. In order to further develop the heatable high pressure cleaning appliance in such a way that it has a high mechanical stability and is producible in a cost-effective manner, it is proposed that the fuel tank is configured as a one-piece plastic hollow body, which forms the housing lower part and is held on a rigid support frame, wherein the support frame forms a shock protector that at least partially surrounds the fuel tank in the circumferential direction.
