Also disclosed is a fluid application system or assembly, and a method of applying fluid using the same, the system or assembly including a source of fluid to be applied to a target object, a siphon gun assembly, an applicator rod, tubing for placing the applicator rod in fluid communication with the siphon gun assembly, and a retaining bracket that secures the tubing to the siphon gun assembly such that the tubing remains in place and does not disconnect from the siphon gun assembly when subjected to a driving force such as water under pressure.

The invention relates to a high pressure cleaning system including a high pressure cleaning appliance operable with at least one variable operating parameter that has a pump assembly, at least one accessory that is in or is bringable into flow connection with a high pressure outlet of the pump assembly, an input unit, at least one control unit coupled to the input unit, and an output unit coupled to the at least one control unit, wherein an object to be cleaned is specifiable by the input unit and a cleaning recommendation is providable on the output unit by the at least one control unit in dependence on the specification, and wherein at least one interaction element is provided for the user, linked to the cleaning recommendation, on the output unit for transmitting interaction information to the at least one control unit, in particular in dependence on the cleaning recommendation.

A pressure washer gun is provided including a safety locking feature that may inhibit unintentional actuation. In an embodiment, the pressure washer gun may include a body portion, and a hand grip portion extending from the body portion. A trigger may be disposed adjacent to the hand grip portion and coupled with a flow control valve for controlling the flow of high pressure fluid through the pressure washer gun. A safety lock may be pivotally coupled with the hand grip portion for movement between a locked position inhibiting movement of the trigger to open the flow control valve, and an unlocked position allowing movement of the trigger to open the flow control valve, the safety lock being biased toward the locked position.

The invention features a method of reconditioning a fluid container including heating for at least one cycle the fluid container to a select temperature for a select time duration; sealing for at least one cycle the fluid container; cooling for at least one cycle the fluid container to a select vacuum for a select time duration in an interior of the fluid container; wherein the select vacuum and the select time duration of the cooling step are selected to draw substantially a fluid from at least one of a pore, a cell and a fiber of the fluid container to a surface of the fluid container. The invention also features methods of infusing an infusion agent into a reconditioned fluid container, and methods for preparing construction materials, devices adapted for the construction material preparation methods, and construction materials including wood reconditioned and prepared in accordance with the methods of the invention.

The invention relates to a system for outputting a mixture generated from at least one gas flow and at least one fluid flow onto a surface (50). The mixture (14) can be fed into a device (7) for outputting the mixture (14). The device (7) for outputting the mixture (14) comprises a gas-carrying line (2) in the interior (39) of which a fluid-carrying line (5) extends axially. The gas-carrying line (2) and the fluid-carrying line (5) are implemented as an outlet device (4) for outputting the mixture (14). The outlet device (4) is further implemented so as to be eccentrically rotatable about the longitudinal axis (12) of the gas-carrying line (2) and further comprises a body (59) for cleaning the surface (50).

Described are trigger locks for pressure washing surface cleaner or general pressure washer spray guns.

A surface cleaner with a connection to a high-pressure medium, consisting of a pot- shaped housing (11) open on one side, in which at least one rotor arm (6) is rotatably mounted on a swivel joint (5) in the center of the housing, wherein one or more cleaning nozzles (27) are arranged on the rotor arm (6), which are connected in a fluid-conducting manner to the high-pressure medium guided through the swivel joint (5), wherein the housing (11) is designed to be able to turn 180 degrees for a second operating mode, wherein the surface cleaner can be operated in the at least two different operating modes, wherein the first operating mode consists of a surface cleaning operation with the housing (11) and the cleaning nozzles (27) arranged therein pointing downwards toward a floor, and wherein the second operating mode is designed as a cleaning operation in which the housing (11), turned over 180 degrees with the cleaning nozzles (27) pointing upwards, is directed toward a cleaning surface arranged at a distance from the floor, characterized in that the surface cleaner has a chassis (8, 9, 17) for supporting the housing (11) in the first and second operating positions relative to the floor surface.
