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 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, a housing that houses the pump mechanism and the electric motor, and a plurality of batteries detachably attached to the housing and configured to supply power to the electric motor.

According to an implementation, a pressure washer system may include a pump and an engine drivingly coupled with the pump. A pressure washer controller may be associated with one or more of the pump and the engine. A battery may be communicatively coupleable with the pressure washer controller for one or more of receiving data from the pressure washer controller and transmitting data to the pressure washer controller. The battery may include a memory module for storing one or more of data received from the pressure washer controller and data to be transmitted to the pressure washer controller.

The disclosure relates to a pressure cleaning device comprising a pressure generating unit for pressurizing a fluid and for dispensing a pressurized fluid via a hose attachment, preferably via a hand gun or via a cleaning nozzle. The pressure cleaning device can be operated in at least two different operating modes. According to the disclosure, a preferably electric pressure sensor for determining an actual operating pressure and/or a flow rate sensor for determining an actual flow rate and a control device are associated with the pressure generating unit. The control device is designed to control the pressure generating unit in particular, based on a respectively set operating mode in accordance with an actual operating pressure and/or an actual determined flow rate.

The present invention relates to a cleaning device assembly, including a spray gun assembly, where the spray gun assembly includes a spray gun housing, a spray gun liquid inlet for a fluid to enter and a spray gun liquid outlet for a fluid to be sprayed are provided in the spray gun housing, and the spray gun housing further includes a handle for holding; a power assembly, where the power assembly and the spray gun assembly are separately disposed, the power assembly includes a pump and a motor configured to drive the pump to work, and the power assembly further includes a fluid inlet for a fluid to enter and a fluid outlet for a pressurized fluid to be sprayed; a power supply assembly, supplying energy to the motor; and a connecting path, connected between the spray gun assembly and the power assembly, where the connecting path includes a liquid outlet pipeline connected between the spray gun liquid inlet and the fluid outlet, where the power supply assembly is independent of the power assembly, and the power supply assembly is disposed on the spray gun assembly.

A fluid flow system for a laundry appliance includes a blower that delivers process air along an airflow path having a heat exchanger. A drain channel receives condensate from the heat exchanger and fluid spray from a spray nozzle for directing lint particles to the drain channel and on to a sump for collecting fluid, including the condensate. A pump seat and a fluid outlet are integrally formed in a sump cover. A pump directs the fluid from the sump to the fluid outlet. A fluid level sensor detects at least minimum and maximum capacities of the fluid in the sump. When the fluid is below the minimum capacity, the pump defines an idle state. When the fluid reaches the minimum capacity, the pump defines an active state. When the fluid exceeds the maximum capacity, the pump directs the fluid to the fluid outlet.

A mobile decontamination system has an internal combustion engine, a generator, a first pump, a boiler and a second pump. The engine is coupled to the generator and to the first pump. The first pump is designed for discharging a first decontamination medium via a first spray lance. The second pump is designed for discharging a second decontamination medium via a second spray lance. A system controller is designed for selectively operating the first pump and the heating boiler in one of at least two different operating modes. In the first operating mode, the first pump delivers a first volumetric flow through the boiler which is at such a high level that the first decontamination medium is in liquid form. In a second operating mode, the first pump delivers a second volumetric flow through the boiler which is at such a low level that the first decontamination medium transfers into gaseous form.

A high-pressure cleaning device, a cleaning dispersion, and a combination of a high-pressure cleaning device with a surface to be cleaned. The cleaning device cleans surfaces soiled by fine particles, particularly motor vehicle surfaces, and includes a high-pressure pump for delivering a cleaning product to a high-pressure jet nozzle. The cleaning product emerges in a high-pressure jet. The cleaning product includes a cleaning dispersion with a carrier fluid and solid cleaning particles having a density of between 0.8 g/cm.sup.3 and 3.5 g/cm.sup.3. Cleaning particles emerge from the high-pressure jet nozzle having a minimum kinetic energy of 1.Math.10.sup.−10 J and a maximum kinetic energy of 2.Math.10.sup.−4 J.

A drive device for a high pressure cleaning appliance includes a motor, the motor shaft of which is rotatably mounted on a motor flange and is coupled to a swash plate arrangement by a planetary gearing, wherein the planetary gearing comprises a sun gear, which is connected to the motor shaft in a rotationally-fixed manner and meshes with planetary gears that are rotatably mounted on a planet carrier and are in engagement with an internally toothed ring gear, and wherein the swash plate arrangement is positioned in an oil housing. So that the drive device has a longer service life and enables a greater selection of materials in the production thereof, the motor flange and the oil housing form separate components, wherein the motor flange comprises the ring gear and the oil housing is fixed to the motor flange, wherein the motor flange forms a centering for the oil housing.
