Venturi-type suction device and methods thereof

A spray and suction system comprising:

• a housing including compressed fluid therein;
• a valve for releasing the compressed fluid within the housing;
• a trigger for actuating the valve;
• a passageway fluidly connected to the housing such that the compressed fluid within the passageway enters the passageway when the trigger actuates the valve, the passageway including a first and a second end;
• a collection housing located at the first end of the passageway;
• and
• a switch interacting with the passageway, the switch having a first position and a second position;
• when the switch is in the first position, the compressed fluid within the housing is forced out of the second end of the passageway to provide for spraying of the compressed fluid;
• and
• when the switch is in the second position, the compressed fluid within the housing is forced toward the first end of the passageway to provide for suction within the passageway to force air into the second end of the passageway toward the first end of the passageway and into the collection housing.
