Disclosed herein are various embodiments of a system and method for operating a surface pressure washer with a wand component. The method may include the steps of cleaning a first surface through a first fluid path, where the first fluid path includes a pump, a pressure regulating valve, a diversion block, and a spray gun, while spray nozzles are not discharging fluid to a second surface, actuating a valve connected to the diversion block, thereby reducing the pressure available to the first fluid path and creating a second fluid path, where the second fluid path includes the pump, the pressure regulating valve, the diversion block and the spray nozzles, where the spray nozzles are configured to rotate above the second surface when the second fluid path is open, and cleaning a second surface underneath the pressure washer system through the second fluid path.

A system and method of protecting plants while spraying having a hood mounted to a farm implement and positioned between plant rows and below plant vegetation. Extending through the hood into a hollow chamber is a hydraulic fitting having a spray nozzle. Heated water is supplied to the hydraulic fitting.

An automatically moving disinfection robot for disinfecting surfaces has a device housing, a drive means for the movement of the disinfection robot within a surrounding area comprising at least one room, a navigation means for the navigation and self-localization of the disinfection, a disinfection means, and a control means for controlling the disinfection activity. The control means controls a locally limited disinfection in only one subregion of the room, or a locally limited disinfection of only one object, in a fully automated manner. The disinfection means has a shielding means for separating the locally limited subregion to be disinfected from adjacent subregions of the same room. The shielding means is a housing, which is open only on one side and which is placed around the object or against the surface to be disinfected, so that the disinfection only takes place within the housing, but not outside of the housing.

An agricultural sprayer unit 700 and a spray deflecting mechanism 70 thereof for the sprayer unit 700 is provided. The agricultural sprayer unit 700 includes a control valve 702, a controller unit 703, a plurality of sprayer nozzles 704, a sprayer tank 706, a sprayer pump 708 and a spray deflecting mechanism 70. The spray deflecting mechanism 70 includes a spray defecting arrangement 72A and a collecting means 70T. The spray deflecting arrangement 70A is adapted to be moved between a deflecting position in which the spray deflecting arrangement 72A is adapted to deflect and re-direct unutilized dispensed fluid from at least one sprayer nozzle 704 to the collecting means 70T thereby restricting wastage of chemical agent/biological agent where the spraying is not required and also to restrict spraying of chemical agent/biological agent to healthy plants.

The disclosure relates to an apparatus (1) for applying a hardening building material against a formwork (2) for manufacturing a solid, load-bearing construction (3), for example a wall of a building, having at least one spray nozzle (4) for spraying the building material in a spraying direction (5), a manipulator (6) which guides the at least one spray nozzle (4) and provides the spraying direction (5), wherein the manipulator (6) is mounted on a movable carriage (7), wherein the formwork (2) is formed by a formwork panel (8) which can be moved together with the carriage (7) and is positioned relative to the spray nozzle (4) in the spraying direction (5) and is oriented substantially transversely to the spraying direction (5). The disclosure also relates to a recess formwork system (25), a reinforcement mat (46), a fastening element (51) and a method for manufacturing a solid, load-bearing construction (3), for example a wall of a building, from a hardening building material.

A method of generating a building assembly that includes spraying a coating material onto a plurality of pieces of substrate disposed on a first assembly face. The spraying includes spraying the coating material onto the plurality of pieces of substrate via a sprayer configured to apply the coating material to a target surface via a nozzle coupled with a mobile storage container storing the coating material, the coating material impregnating voids of the substrate. The method also includes allowing the coating material impregnating the voids to dry and harden and become rigid to generate the building assembly.

While the described wand can include any suitable component, in some cases, it includes a wand head having a vacuum port with a front face and a back face, a jet port that is coupled at the back face of the vacuum port, and a jet that is coupled to the jet port, the jet being configured to spray effluent through the vacuum port to a surface to be cleaned. In some cases, the front face includes a first jog that extends from a front side of the front face and across a width of the front face. In some cases, the second face includes a second jog that extends across a width of the back face of the vacuum port such that the second jog extends into the vacuum port and defines a second recess at a back side of the back face. Additional implementations are also described herein.
