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.

A device includes a tank configured to contain a quantity of water; a pump configured to extract water from the tank and to pressurize the water; a connector in fluid communication with the tank and coupled to the tank so as to receive pressurized water produced by the tank and convey the pressurized water through the connector; and a plurality of lances configured to be interchangeably coupled to the connector to receive the pressurized water from the connector and to expel the water, wherein the plurality of lances includes a fog lance including a fog nozzle having an aperture that is sized from 0.35 mm to 0.45 mm, wherein the fog nozzle (a) includes a fog piston configured to cause rotational movement of water passing therethrough, (b) produces a flow rate of less than 0.17 liters per minute, and (c) produces an output that travels at least 1 meter.

A pressure washer disclosed herein may include a pump mechanism configured to pressurize water supplied through a water inlet and pump out the water through a water outlet, an electric motor configured to drive the pump mechanism, and a housing that houses the pump mechanism and the electric motor. An outer surface of the housing most proximate to the electric motor may have a shape that does not allow the pressure washer to stand on its own when the outer surface is used as a placement surface.

A motor arrangement (10) is disclosed as including an AC motor (12) with an output, a DC motor (14) with an output, a power transmission mechanism (18) including a first one-way clutch (20) and a second one-way clutch (22), the power transmission mechanism being coupled with the output of the AC motor via the first one-way clutch and coupled with the output of the DC motor via the second one-way clutch.

A pump assembly and a high-pressure cleaning apparatus, the pump assembly comprises a motor assembly, a motor housing for receiving the motor assembly, a transmission assembly driven by the motor assembly, a pump, and a pipe assembly connecting the motor housing and the pump. Mutually independent heat dissipation portions are provided at two sides of the motor housing. Compared with the prior art, the present invention meets the requirements of heat dissipating by providing independent heat radiation parts on both sides of the motor housing. The high-pressure cleaning apparatus has a small volume, a high efficiency, a good cooling, and easy to carry.

The present invention relates to a handheld high-pressure cleaning machine, including: a main machine housing, allowing detachable attachment of a battery pack, where the main machine housing includes a main body portion; a liquid outlet; a first handle; a motor; and a pump, where a battery pack mounting portion includes a first battery pack mounting portion and a second battery pack mounting portion, and the battery pack includes a first battery pack and a second battery pack; and the first battery pack mounting portion and the second battery pack mounting portion are respectively disposed on left and right sides of a middle plane in a manner that a distance W2 between a leftmost edge of the first battery pack mounting portion and a rightmost edge of the second battery pack mounting portion is not greater than a width W1 of the main body portion.

A portable unit having a lance incorporating a steam generator and a sanitizer tank, which can improve the sanitizing and disinfection of surfaces with steam, and having a set of lines and power supply cable and a human-machine interface, which enables the supply of the fluids and electrical energy either in situ on any local network that has a water and power supply and a centralized air-blowing/suction device, or on a user-portable module that incorporates autonomous arrangement for managing the fluids and electricity.

A frame for a pressure washing device is provided. The frame comprises at least one tubular member and a plurality of bends are provided in the tubular member. The frame is preferably devoid of a support plate and is adapted to receive at least one of a power source and a pump that is directly mounted to the frame.

A hand-held high-pressure cleaning machine includes: a housing, having a handle for grasping; functional components, including a motor and a pump driven by the motor; and a liquid inlet, disposed on the housing and capable of being connected to an external water source by a water pipe. The hand-held high-pressure cleaning machine further includes an adapter suitable to be connected between the liquid inlet and a portable container, and is connected to the external water source by the water pipe or connected to the portable container by the adapter. In the present invention, the portable container configured to hold liquid is mounted to the hand-held high-pressure cleaning machine by using the adapter, so that it can be flexibly moved together with the hand-held high-pressure cleaning machine. The present invention further provides an adapter suitable to be connected between a portable container and a hand-held spraying device.

The disclosure includes a watercraft cleaning system that includes a housing, a water input line, a pump and motor system, a high-pressure output line, and a heater. The cleaning system can be arranged and configured to be coupled to a dock post located adjacent a watercraft. The system can easily and conveniently allow watercraft personnel to clean the watercraft.
