A wash system includes a wash unit associated with a mobile unit for providing wash fluid, one or more nozzles for streamline injecting wash fluid provided by the wash unit directly into an engine inlet, and an articulating arm for use in positioning the one or more nozzles. The wash unit is physically spaced from a surface of the engine inlet cowling during a washing process. The articulating arm is operable via one of a hydraulic, pneumatic, electrical, or mechanically hand-driven operating means.

A handheld car washing implement that includes a handle defining a channel for receiving a flow of water, the handle including a nozzle in communication with the channel, wherein the handle further includes a plurality of teeth, extending radially outward from the nozzle; a sprayer, defining a second channel having a first and a second end, wherein the second end terminates in a second nozzle and the first end is dimensioned to receive at least a portion of the nozzle of the handle such that the flow of water is directed into the second channel, wherein the sprayer further includes a plurality of tabs, spaced to engage at least one of the tabs and a canister in communication with the second channel via a port, and configured to store and deliver a detergent to the second channel when water is flowing through the second channel.

An improved structure of gyrating nozzle spray gun includes a grip including an air inlet and a trigger-controlled valve seat, a gas delivery tube connected to the valve seat, and a gyrating nozzle head including a connection nut threaded onto a front tubular mating connection screw rod of the gas delivery tube, an end cap threaded onto outer thread of the connection nut, a bearing positioned in the end cap, and a rotator mounted in the bearing and rotatable with an inner race of the bearing and defining therein a gas accumulation chamber for receiving compressed air from the valve seat via the gas delivery tube and the connection nut and an oblique jet hole eccentrically located in the front wall thereof for ejecting compressed air and causing the rotator to rotate during ejection of compressed air.

A vehicle washing assembly for washing, drying, and vacuuming a vehicle includes a housing having a base wall, a peripheral wall that is attached to and extends upwardly from the base wall, and a top wall that is attached to the peripheral wall opposite the base wall. The peripheral wall bounds an interior area. A pressure washer unit is mounted to the housing and configured to expel a fluid under pressure in a selected direction. A blower unit is mounted to the housing and configured to suction air inwardly through an inlet and to blow air outwardly through an outlet. Both the inlet and the outlet are mounted to the housing. A catch is in fluid communication with the inlet for capturing debris suctioned in through the inlet. A power supply is attached to the housing and is electrically coupled to the pressure washer unit and the blower unit.

A surface wiper device which includes a carrier which supports a blade. The carrier attaches to a wiper arm which urges the blade against and moves the blade across the surface of a windshield. The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

A car washing system comprises a filtering unit, a pure water pipeline, a waste water pipeline, a washing pipeline, an optional first branch line, and a second branch line. The filtering unit comprises an RO filter membrane, a filtering pipeline and a booster pump. One end of the filtering pipeline is connected to the inlet of the RO filter membrane. The booster pump is set in the filtering pipeline. The pure water pipeline is connected between a pure water outlet of the RO filter membrane and one end of the washing pipeline. The joint of the pure water pipeline and the washing pipeline is provided with a high-pressure pump. One end of the waste water pipeline is connected with waste water outlet of the RO filtering membrane, and the other end is a discharge end. Water in the washing pipeline flows through the second branch line.

A multi-purpose tool for cleaning automobile windshields and windows comprising a telescoping body having a first and a second end, an ice scraper and a snow brush member attached to the telescoping body at the first end, a scrubbing member and a squeegee attached to the body at the second end, a detachable flashlight and a spray unit with a detachable spray bottle removably attached to the telescoping body, wherein the telescoping body extends intermediate the first end and the second end.

The carrier further provides a plurality of outlets each of which communicate between a hollow passage inside the carrier and a location on the external surface of the carrier. A fluid can be delivered from a fluid source fluidicly coupled to the hollow passage of the carrier under sufficient pressure to be dispersed from the plurality of outlets onto the windshield during movement of the blade. A fluid heater can be thermally coupled with the fluid delivered from the fluid source to the plurality of outlets to increase the temperature of the fluid dispersed onto the windshield. The fluid can be sufficiently heated to generate a heated gas.

A powered tool may be improved by mounting a light thereto. Some examples of a powered tool include a polisher tool adapted to polish and/or buff a work surface. Other examples of a power tool include various rotary, orbital, reciprocating, or other types of handheld tools. In various examples, a bracket can secure a light to a polisher or buffer tool so that the work surface can be directly illuminated to improve the efficiency and comfort of the tool operator. The bracket can be repositioned on the hand tool to optimize light direction to enhance the effectiveness of the hand tool.
