An electric power washer apparatus and system including a water inlet that receives pressurized water, a pump fluidly connected to the water inlet, a motor powering the pump to increase the pressure of the pressurized water, a first heat exchanger fluidly connected to the pump, the first heat exchanger including an in-cast heating element, a gun fluidly connected to the first heat exchanger, and preferably a second heat exchanger connected in series or parallel to the first heat exchanger to provide additional heating to the fluid as it passes through the system. The system further preferably includes an unloader, a pressure regulating valve, a thermostat, a detergent system, and may include a variety of styles of heat exchangers so long as at least one is an in-cast heat exchanger. These other styles of heat exchangers may include a tank style heating element or an encased style heating element.

Disclosed is a method and apparatus for performing high volume washing, namely, using drones to perform cleaning services. A drone is navigated about a cleaning path; the cleaning path being either pre-defined or delineated in real-time. A cleaning solution is pumped to a solution distribution mechanism of the drone, wherein the cleaning solution is directed onto the surface to be cleaned. The solution is stored in a supply tank that may be integrated into the body of the drone or outfitted as a standalone structure. A temperature regulator is integrated with the supply tank in order to control a wash temperature of the cleaning solution. The solution distribution mechanism may be rotatable about 360 degrees. A camera array observes a spray area of the solution distribution mechanism, wherein a live feed is transmitted to a monitoring unit.

A pressure washer includes a motor configured to drive a pump, a frame having first and second end portions, a handle having first and second end portions, and a rotating joint rotatably coupling the first end portion of the handle to the second end portion of the frame. The rotating joint includes a locking mechanism to selectively lock the position of the handle relative to the frame. The handle rotates between a storage position and an extended position. In the storage position, the second end portion of the handle is positioned near the first end portion of the frame such that the motor and the pump are located within a volume defined by the first and second end portions of the handle and the frame. In the extended position, the second end portion of the handle is spaced apart from the frame.

A detergent dosing controller that is convenient to use and has better effect is disclosed herein. One side of the main passage is a water inlet (101), another side of the main passage is outlet (102) connecting to liquid inlet of washing bucket, and valves A(2), B(3), C(4), D(5), pump (6) and nozzle (7) are equipped. The inlet of valve A connects to the bypass orifice A(a) of the main passage, inlet of valve B connects to liquid storage tank of detergent A, outlets of valve A and valve B connect to inlet of valve C, inlet of valve D connects to liquid storage tank of detergent B, outlets of valve C and valve D connect to inlet of the pump, outlet of the pump connects to bypass orifice B(b) of the main passage, and for the relative location of bypass orifices A and B of main passage, bypass orifice A is relatively close to the inlet of main passage, bypass orifice B is relatively close to the outlet of main passage, the nozzle connects to main passage by concatenation and between bypass orifices A and B. The invention is applicable to the dosing of detergent for electric washing equipments.

The present invention relates generally to an apparatus for cleaning or otherwise treating a floored surface that includes a platform adapted to support the weight of an operator. In addition, one embodiment of the present invention is capable of generally performing 360 degree turns to facilitate the treatment of difficult to access portions of the floored surface.

A firehose cleaning apparatus containing a washing chamber including optionally a plurality of rotating brushes and a plurality of spray nozzles. The firehose cleaning apparatus is constructed so as to permit a firehose to be fed through the washing chamber for cleaning. The firehose cleaning apparatus is portable and can be moved in accordance with user preference.

A high-pressure cleaning system with a high-pressure cleaning appliance including a pump, a motor, a pump inlet and a pump outlet, and a control device, and with at least one discharge unit adapted to be brought into fluid connection with the pump outlet for discharging pressurized cleaning liquid is disclosed. In order to further develop the high-pressure cleaning system in such a way that as good a cleaning result as possible is more easily achievable, the high-pressure cleaning system includes a detection unit by which the type of discharge unit presently in fluid connection with the pump outlet is detectable and which is connected in a signal-transmitting manner to the control device, at least one conveying parameter of the high-pressure cleaning appliance being automatically adaptable by the control device to the detected type of discharge unit. A discharge unit for such a high-pressure cleaning system is also disclosed.

A water cleaning system is provided that includes a water conditioner operable among a plurality of different cleaning modes selected from the group consisting of a tap water mode, a conditioned water mode, a tap water and cleaning agent dispensing mode, a conditioned water and cleaning agent dispensing mode, a pump assisted dispensing mode, and any combinations thereof.

An all-electric pressure washer heater module having a heating coil and a heating element is disclosed. A system for all-electric pressure washing is further disclosure. In particular, the all-electric pressure washer heater module contains the heating element from exposure to corrosion and fouling.

A mobile cleaning system to be used for cleaning organic liquids from a hard surface includes tanks for storing water, and for storing used, dirty water after cleanup. A water-based cleaner is sprayed onto the spill, which can be, but need not be, done in connection with the cleanup system. A high throughput vacuum system removes the hot water and the spill materials concurrently as the hot water is applied to the treated area. The vacuumed liquids are stored in an on-board tank for later disposal.
