Apparatus for cleaning a surface with a liquid jet, the apparatus having: a primary fluid conduit having a longitudinal axis and two ends, a fluid-intake end and a fluid-exit end; a first motor-driven drive assembly configured to engage the primary fluid conduit and turn the primary fluid conduit about the primary-fluid-conduit longitudinal axis; a first motor configured to engage the first motor-driven drive assembly; a section of the primary fluid conduit being inside of an adjacent penetration sleeve; a section of the penetration sleeve being inside of a piston sleeve; the piston sleeve configured to engage the penetration sleeve and move the penetration sleeve back and forth along a penetration-sleeve linear path over a primary-fluid-conduit exterior surface; an actuator configured to engage the piston sleeve and move piston sleeve back and forth along a piston-sleeve linear path; a penetration-sleeve end being attached to an extension sleeve that has a first end and a second end; the extension-sleeve second end being attached to a pull rod or a pull cable; the pull rod or the pull cable being attached to a nozzle anchor and configured to pull on, push against, or release tension from the nozzle anchor as the penetration sleeve moves back and forth along the penetration-sleeve linear path; the primary-fluid-conduit fluid-exit end being attached to a flexible conduit; the flexible conduit being attached to a nozzle tip having the nozzle anchor thereon; and a continuous fluid-flow channel that extends from the primary-fluid-conduit fluid-intake end through the flexible conduit.

A fine particle sprayer including a nozzle for dispersing a liquid disinfectant into a spray plume of droplets and a means for directing pressurized air below the spray plume to increase droplet transfer efficiency, and above and around the spray plume to prevent errant droplets from drifting toward an operator. A sprayer system includes a sprayer, a housing, and a blower that may be removably attached to the sprayer for generating an air stream below the droplets to improve droplet transfer efficiency.

A mister kit provides components to assemble as needed and where needed misters of customizable configurations capable of on-site assembly, connectable with local business and residential water sources, and with the ability to be secured to nearby structures.

An applicator for a syringe is provided that includes a hub configured to be disposed at least partially within a nozzle of the syringe and defining a fluid passage therethrough, with one or barbs on the hub that frictionally and sealingly engage an interior of the nozzle in a manner minimizing void space associated with waste of deliverable material, and an applicator tip extending distally from the hub. The barb(s) may have varying diameters in order to enable the applicator to be engaged and utilized with syringes having different diameter nozzles. Further the fluid passage through the hub and applicator tip is dimensioned to minimize the volume of material that is retained within the applicator after use, thereby increasing the volume of material that can dispensed from the syringe for use in a procedure or procedures and minimize waste.

A rotating sprinkler for irrigation is disclosed. The sprinkler can include a turret and a stream conditioner positioned in the turret. The stream conditioner can include a plurality of fins forming a plurality of flow regions. One or more of the plurality of flow regions can have a cross-sectional flow area that decreases in a downstream direction towards the primary port so as to accelerate the pressurized water through the stream conditioner. The plurality of fins can further straighten the water.
