A wand apparatus for controlling a pressure washing system and an associated method for controlling a pressure washing system is provided. The wand apparatus may include a first wand portion and a second wand portion. The wand apparatus may further include a chemical control assembly that includes a housing and a chemical control element. The housing defines an outlet aperture, an inlet aperture, and a chemical control aperture. The chemical control aperture is configured to operably engage the chemical control element. The outlet aperture is configured to operably engage the first wand portion, and the inlet aperture is configured to operably engage the second wand portion. Further, operable engagement of the chemical control element may provide for switching the wand apparatus between a chemical spray configuration and a wash spray configuration.

A multi reservoir dispenser includes a first reservoir for holding a first fluid and a second reservoir for holding a second fluid. The dispenser further includes a pump mechanism that includes a pivotable trigger and a first plunger cavity that is disposed along the first flow path for receiving the first fluid and a second plunger cavity for receiving the second fluid. The pump mechanism also includes a first plunger that is disposed and movable within the first plunger cavity and a second plunger that is disposed and movable within the second plunger cavity. A selectable actuator is movable between: (a) a first position in which only the first plunger of the pump mechanism is actuated for discharging only the first fluid through a first orifice of a nozzle by causing the first fluid to flow along a first flow path; and (b) a second position in which only the second plunger of the pump mechanism is actuated for discharging only the second fluid through a second orifice of the nozzle by causing the second fluid to flow along a second flow path.

A robotic applicator and a coating system and method for real-time control of the application of one or more coatings onto the surface of a substrate. The coatings can include various primer layers, adhesive agents, tinting/coloring agents, and/or chemical solvent layers onto glass substrates. A single robotic applicator can include a pair of applicators to apply different coating layers onto the substrate surface. The overall system and method includes an initial optical vision system, along with a series of optical vision systems, and a series of robotic applicators, that cooperate with a central processing unit to customize the coating sequence and pattern for the particular substrate material, shape, and/or intended use of the coated substrate.

A liquid object dispenser includes a body, multiple containers (500), a transfer table (110) including multiple container accommodating parts accommodating the multiple containers, the transfer table being able to relatively transfer the container accommodating parts to a replacement position in the body at which the containers are replaced and to a dispensing position in the body at which the stored liquids of the containers accommodated in the container accommodating parts are dispensed, and a liquid object dispensing part configured to cause the stored liquids of the containers accommodated in the container accommodating parts at the dispensing position to be dispensed.

A drain gun includes a handle and a trigger. The handle includes a channel and a plurality of inlets. The inlets feed the channel. The trigger causes a staged release of a plurality of fluids from a plurality of cartridges to the channel via the inlets when the cartridges are stored in the handle and feeding the inlets.

Disclosed is a system for dispensing a fluid. The system may include a cartridge and a main unit configured to be coupled to the cartridge. The cartridge may comprise a container which may include at least one opening and at least one membrane in fluid communication with the at least one opening. Further, the cartridge may include at least one actuator which, upon activation, may be configured to cause the fluid to pass through the at least one membrane. Furthermore, the cartridge may include at least one storage device configured to store fluid data representing at least one characteristic associated with the fluid. Additionally, the cartridge may be operably associated with at least one controller configured to control activation of the at least one actuator based on the fluid data. The controller may be configured within the cartridge or be coupled to the cartridge by way of, for example, a main unit.

Systems and apparatuses include a prime mover, a pump driven by the prime mover, and a sprayer receiving a flow of water from the pump. The sprayer includes a sprayer housing, a first fluid reservoir coupled to the sprayer housing, a second fluid reservoir coupled to the sprayer housing, a chemical selector coupled to the sprayer housing and movable between a first chemical position and a second chemical position, a high pressure selector coupled to the sprayer housing and movable between a high pressure position and a chemical spray position, and a nozzle assembly in communication with the chemical selector and the high pressure selector.

A sunscreen application assembly includes a canister that has a plurality of chambers. Each of the chambers is fluidly discrete with respect to each other and each of the chambers contains a liquid. A pump unit is movably coupled to the canister and the pump unit is in fluid communication with the interior of the canister. The pump unit is selectively manipulated. The pump unit is selectively aligned with a selected one of the chambers to urge the liquid in the selected chamber outwardly therefrom.

The sprayer includes a sprayer housing defining a chamber, and a cylinder within the chamber. The cylinder defines more than one discharge tube positioned in a longitudinal direction within the sprayer housing, the cylinder being selectively rotatable within the chamber. More than one suction tube extends from a lower portion of the sprayer housing. The more than one suction tube is in selective fluid communication with the more than one discharge tube of the cylinder, as the cylinder is rotated within the chamber. The foam sprayer attachment includes a major body defining a discharge channel and a screen traversing the discharge channel. The major body includes a base with a connecting structure that is a raised lip or a cut-out area that conforms the base to a raised ridge on a discharge connection of the sprayer. The connecting structure includes a pair of non-raised lips bracketing each connecting structure.

An apparatus includes a selectively actuated fluid system having a plurality of selected fluid reservoirs, for example replaceable cartridge-type fluid reservoirs. A first subset of the reservoirs can be selectively actuated to dispense an individual fluid from the selected reservoir. A second subset of the reservoirs can be simultaneously actuated to dispense two or more fluids in mixed form.
