Air recirculating surface cleaning device

A fluid recirculating cleaning device, comprising:

• an exhaust port defining an exhaust port longitudinal axis, said exhaust port having an exhaust end and a fluid source end, said exhaust end defining a first cross-sectional area;
• a suction port defining a suction port longitudinal axis, said suction port having a fluid entrance end and a fluid exit end, said fluid entrance end defining a second cross-sectional area that is greater than said first cross-sectional area, said suction port defining a second outer surface that extends from said entrance end toward said fluid exit end;
• a vacuum blower motor for creating fluid flow away from said vacuum blower motor and toward said exhaust end, said vacuum blower motor sucking fluid in through said fluid entrance end;
• wherein said exhaust end is recessed from said fluid entrance end, and wherein said exhaust port is oriented to discharge fluid toward said second outer surface in a manner that impinges discharged toward and impinges upon said second outer surface.
