Apparatus for clearing waste from a surface

An apparatus for clearing waste from a surface, comprising:

• a vacuum suction head having a suction opening for accepting waste material;
• a waste receptacle for storing waste material that are vacuumed through said suction opening, said waste receptacle having a discharge port through which waste material stored within said waste receptacle may be discharged for emptying said waste receptacle;
• a vacuum passage fluidically connecting said suction opening and said waste receptacle;
• a reversible vacuum pump in communication with said waste receptacle for alternately providing a vacuum on said waste receptacle and pressurizing said waste receptacle;
• a vacuum passage valve disposed across said vacuum passage, said vacuum passage valve operable to alternately permit or preclude a flow through said vacuum passage;
• a waste receptacle discharge valve disposed across said discharge port, said waste receptacle discharge valve operable to alternately permit or preclude a flow through said discharge port;
• a fluid reservoir for holding a quantity of chemical solution;
• a pump fluidically connected to said fluid reservoir and operable to pump chemical solution therefrom;
• a fluid passage connected at one end to said pump for receiving pumped chemical solution;
• and
• a first spray nozzle connected to an end of said fluid passage and configured to jet fluid from said fluid passage in a direction away from an operator and against material on the surface.

• a fluid reservoir for holding a quantity of fresh water;
• a chemical concentrate container for holding a quantity of chemical concentrate;
• a pump fluidically connected to said fluid reservoir and operable to pump fresh water therefrom, said pump fluidically connected to said chemical concentrate container and operable to pump chemical concentrate therefrom;
• a valve operable to selectively and fluidically connect said fluid reservoir to said pump, fluidically connect said chemical concentrate container to said pump, or fluidically connect said chemical concentrate container and said fluid reservoir concurrently to said pump;
• a fluid passage connected at one end to said pump for receiving pumped fluid therefrom;
• and
• a first spray nozzle connected to an end of said fluid passage and configured to jet fluid from said fluid passage in a direction away from an operator and against material on the surface.

• a waste receptacle lid disposed across said discharge opening, said waste receptacle lid rotatably mounted for rotation between a position wherein said discharge opening is sealed by said waste receptacle lid and a second position wherein said discharge opening is open to permit a flow through said discharge port;
• a fluid passage configured at one end to be connected to a source of pressurized water by a garden hose;
• a first spray nozzle connected to an end of said fluid passage and configured to jet fluid from said fluid passage in a direction away from an operator and against material on the surface;
• and
• a control valve disposed across said fluid passage, said control valve operable to alternately permit or preclude a flow through said fluid passage.
