A high-pressure cleaning appliance is provided, including a housing having a motor and a pump, driven by the motor, arranged therein, and including at least two rotatably mounted running wheels, a push bar movable back and forth between a parking position and an operating position, and a locking device for releasably locking the push bar, the locking device including an actuating member which is coupled by at least one coupling member to at least one locking member which interacts with the push bar and is movable from a locking position to a release position by actuating the actuating member. So that the high-pressure cleaning appliance can be assembled more cost-effectively and more easily, the locking device includes a prefabricated constructional unit which forms the actuating member, the at least one coupling member and the at least one locking member and is movably mounted on or in the housing.

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.

Systems and methods for a pressure washer or other system to transport and distribute liquid are provided with an improved frame and handle. The pressure washer system includes a frame, a container carried by the frame, a pump, a dispenser, and a handle connected to the frame. The handle is rotatable relative to the remainder of the pressure washer system from a use-based position in which the handle is upwardly oriented and can be pushed to move the pressure washer from one location to another, and a stowed position in which the handle is downwardly oriented such that the pressure washer system has reduced dimensions and can more easily be stored. For instance, an upper portion of the handle can be releasably secured to a lower portion of the handle associated with the frame. The upper portion of the handle can be rotated relative to the lower portion.

According to examples, a pressure washer may include a main housing including an inlet, an outlet, and a pump to force liquid to enter the main housing through the inlet and to exit the main housing through the outlet. The pressure washer may also include a roll cage surrounding the main housing, in which the roll cage may include a pair of support bars, a crossbar movably mounted to the pair of support bars; and a latch mechanism to releasably secure the crossbar to at least one of the pair of support bars. The crossbar may be spaced from the main housing to form a storage space, in which the crossbar is movable between multiple positions to enable ready access to the storage space.

A solar panel cleaning robot is provided and has a robot body. The robot body can move on at least one solar panel. A cleaning device, a power system, a control system and an electric power system are disposed on an internal or an external of the robot body.

A paint removal apparatus for cleaning paint from masking devices includes a support base having a plurality of engagement features that are each configured to securely engage at least one paint masking device. A spray nozzle is aimed in a fixed direction toward the support base and configured for spraying a pressurized stream of water at a desired velocity that removes paint from an exterior surface of at least one of the masking devices engaged at the support base. The support base is configured to successively move the masking devices engaged at the engagement features into the pressurized stream of water, such as to provide a generally continuous cleaning operation of masking devices. During movement or rotation of the support base, an exposed portion of the support base may extend from a spray enclosure for removing cleaned plugs from and loading painted plugs onto such an exposed portion.

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 sensor washing device that includes a washer housing that has a ring portion and a fluid source attachment. The fluid source attachment is configured to receive fluid. The ring portion has a main opening for receiving a detecting head of the sensor, an attachment side configured for mounting the washer housing, and a washing side configured to frame the detecting head of the sensor. The washing side is in fluid communication with the fluid source attachment. A plurality of nozzles are disposed in a transition portion of the washer housing between the ring portion and the fluid source attachment of the washer housing. The plurality of nozzles are configured to discharge fluid to the washer side radially inwardly towards the main opening for cleaning the detecting head of the sensor.

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.

A pressure washer includes a mounting platform, a prime mover supported by the mounting platform, a pump driven by the prime mover, a frame configured to support the mounting platform, a handle extending upward from the mounting platform, a spray gun including a barrel, a handle, and a nozzle, and an accessory tray attached to the frame proximate the mounting platform, the accessory tray including a spray gun clip configured to hold the barrel and a spray gun receptacle configured to hold the nozzle.
