A washing container for washing or maintaining various objects includes opposite side portions, end portions, and a bottom portion. Embodiments include at least one lower support having an engagement gap extending between lower support arms and configured to releasably secure the objects. Some embodiments include opposing lower supports that secure opposite ends of the objects. An upper support arm may be used independently or together with one or more lower supports to secure one or more objects, in various positions, within the washing container. A perforated support platform support the objects above the bottom portion of the washing container and allows fluids and debris to pass to the bottom portion and into a drain trough. A debris basket within the trough limits the passage of debris into a drain.

A spray gun for a high-pressure cleaning appliance is provided, with a gun casing, in which is arranged a valve, which has a through duct which extends from a valve inlet to a valve outlet, and has a closure body which, in a closed position, bears in a fluid-tight manner against a valve seat and which is adapted to be moved, with the aid of a hand lever mechanically coupled to the closure body, into an open position spaced apart from the valve seat, and with an electric apparatus which has an electric display device and at least one battery. The electric apparatus has an electric casing which is sealed against sprayed water and forms a sub-unit adapted to be handled independently, wherein all of the current-carrying components of the spray gun are arranged in the electric casing and are separated galvanically from the remaining components of the spray gun.

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° turns to facilitate the treatment of difficult to access portions of the floored surface.

A working machine may be provided with: a case configured to store water therein; and a working machine body configured to discharge water supplied from the case, in which the working machine body is detachably mounted on an upper surface of the case.

A high-pressure cleaning system is provided, including a high-pressure cleaning apparatus having a high-pressure pump for increasing the pressure of a cleaning liquid, and two or more discharge units for discharging the cleaning liquid, which are different and can be selectively brought into fluid communication with a pump outlet of the high-pressure pump, wherein the discharge units are connectable to an operating unit or wherein an operating unit is arranged on at least one discharge unit. The high-pressure cleaning system includes an input unit via which at least one output parameter is predeterminable by a user and is adjustable by way of a control unit coupled to the input unit. The high-pressure cleaning system includes an output unit coupled to the control unit and capable of providing an indication depending on the predetermination made by the user, said indication including a recommendation of at least one discharge unit.

An improved hot water pressure washer utilizes a combination of technologies to achieve lower emission levels and increased operational efficiency. A forced air natural gas or forced air oil burner utilizes a flue gas and recirculation line to lower carbon monoxide and NOx emissions from a burner. A flue gas heat exchanger is utilized to lower the temperature of the exhaust gas. The lower exhaust gas temperatures allow for lower cost materials to be utilized. The efficiency levels of a hot water pressure washer are increased over known devices.

Disclosed is a two-in-one cleaning apparatus. The two-in-one cleaning apparatus includes a positioning assembly, a booster pump, an automatic hose reel, an intermediate connecting rod, and a spray gun body. The booster pump, the automatic hose reel, the intermediate connecting rod, and the spray gun body are all detachably mounted on the positioning assembly. The booster pump is provided with a water inlet and a water outlet, a water inlet pipe is arranged at the water inlet of the booster pump, and the water outlet of the booster pump is connected to the automatic hose reel. The automatic hose reel is provided with a mounting bracket, the positioning assembly is provided with a positioning support plate matching the mounting bracket, and the automatic hose reel is mounted on the positioning assembly through matching between the mounting bracket and the positioning support plate. The spray gun body is detachably connected to the booster pump and the intermediate connecting rod, respectively. The disclosure has the beneficial effects of being convenient to carry, high in stability, wide in application range, capable of meeting different use requirements, convenient to dismount and mount, simple in structure and convenient to operate.

A device for sanitizing a unit of an air conditioning system having a source of sanitizing fluid, means for the controlled delivery of a jet of sanitizing fluid, suctioning means to generate suction flow is provided. The device has suction opening shaped to direct the suction flow towards a determined direction with respect to the direction of the jet of sanitizing fluid. The suction opening is smaller than the unit of the air conditioning to be sanitized in order to be alternately moved from a first portion of the unit towards a second portion of the same unit.

The present invention relates to a device for cleaning and/or disinfecting surfaces, particularly for cleaning inner surfaces of the toilet bowl. The device comprises an elongated housing connected to a bottle with the cleaning and/or a disinfecting liquid, and a pumping mechanism for pressurizing said liquid composition, and at least one nozzle for the output of said liquid composition, wherein the nozzle is in fluid communication through a conduit of the device with said pumping mechanism. The pumping mechanism is provided at one side of said housing and said at least one nozzle is provided at the opposite side of the housing.

Embodiments of the present invention disclose apparatuses and methods for a pressure washer with 100% cool bypass operating without a soap or detergent metering valve, high pressure detergent, a booster pump, or thermal relief valve.
