## Abstract

An apparatus for cleaning surfaces, particularly solid surfaces, includes an outer housing and an inner housing configured to substantially encapsulate a surface being cleaned, a vacuum source traversing the outer housing, a rotating coupler, an impeller, at least one fluid jet coupled to the impeller, and at least one air induction port. The vacuum source is configured to induce air through the air induction ports past the impeller blades causing the impeller to rotate, which causes the rotating coupler and the fluid jets to rotate. Because the rotation of the fluid jets is due to induced air, the fluid jets can be positioned at any angle desired, including a negative angle.

## Claims

### Claim 1

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
at least one fluid jet coupled to said rotating coupler;
wherein rotation of said impeller causes said rotating coupler and said at least one fluid jet to rotate;
an inner housing, said inner housing separating said at least one fluid 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 being configured to further direct said induced air past said impeller; and
lower baffles within said inner housing, said lower baffles directing said induced air towards the center of the surface within said outer housing.
