Patent ID: 8510902

Claim:
An apparatus for cleaning surfaces, comprising: an outer housing having at least one air induction port traversing said outer housing; a vacuum source coupled to said outer housing; a rotating coupler; an impeller coupled to said rotating coupler and positioned below the at least one air induction port; and at least one liquid jet coupled to said rotating coupler, positioned below the impeller, and coupleable to a source of liquid; wherein rotation of said impeller causes said rotating coupler and said at least one liquid jet to rotate; an inner housing, said inner housing separating said at least one liquid jet and said impeller from said vacuum source, said air induction port traversing said inner housing, wherein said vacuum source induces air through said air induction port past said impeller, causing said impeller to rotate; upper baffles within said inner housing, said upper baffles extending circumferentially around a rotation volume of the impeller, said upper baffles being configured to further direct said induced air past said impeller; and lower baffles within said inner housing, said lower baffles being directly connected to said upper baffles directing said induced air towards a center of the surface within said outer housing.
