Abstract
A mobile spraying and cleaning apparatus is provided in the form or a wheeled cart. The cart includes a lower housing that supports and carries a reservoir. The reservoir sits atop the housing over a chamber that contains a fluid pump. Cleaning fluid from the reservoir flows by gravity feed to the pump, and pressurized cleaning fluid is discharged through a spray nozzle coupled to the end of a hose. By wheeling the cart into an area to be cleaned, the user can then use the pressurized spray to clean the area. Preferably, the unit is molded of durable plastic and presents a smooth, attractive exterior that is easy to keep clean and professional looking. If desired, an anti-microbial agent can be added to the plastic to inhibit microbial growth on the unit.
Claims16
A mobile spraying apparatus comprising:
- a wheeled cart having a lower unit defining an interior chamber having an open upper end, the wheeled cart further including an upper reservoir unit nested into the open upper end of the lower unit;
- a pump within the lower unit;
- a first conduit for communicating fluid from the reservoir to the pump;
- a second conduit for communicating pressurized fluid from the pump;
- a plurality of wheels coupled to the lower unit to enable the lower unit to roll along a supporting surface,
- and a handle coupled to the lower unit for enabling a user to push and pull the mobile spraying apparatus over the supporting surface.
A mobile spraying apparatus comprising:
- a reservoir;
- a wheeled cart carrying a pump and structure for supporting the reservoir above the pump;
- a fluid conduit for carrying fluid from the reservoir downwardly to the pump by force of gravity;
- and
- a user controlled discharge nozzle coupled to the pump for directing fluid pressurized by the pump against a surface to be cleaned;
- and
- the wheeled cart including a housing defining an interior chamber having an open top adapted to receive and support the reservoir therein, the reservoir thereby forming a closure for the interior chamber.
A mobile spraying apparatus comprising:
- a molded plastic lower unit defining an interior chamber having an open top;
- a fluid pump disposed within the interior chamber of the lower unit;
- one or more wheels coupled to the lower unit for enabling the lower unit to be wheeled over a supporting surface;
- a molded plastic reservoir supported by the lower unit and positioned over the open top of the interior chamber so as substantially to fully occlude the open top of the interior chamber;
- and
- a fluid conduit for providing fluid communication between the reservoir and the pump under gravity feed.
