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.

1. An apparatus for cleaning a surface, comprising: a housing;an impeller positioned in the housing;an air induction port positioned in the housing and above the impeller, to direct a flow of air to the impeller and rotate the impeller;a liquid jet coupled to the impeller; anda baffle carried by and rotatable with the impeller, the baffle extending circumferentially around a rotation volume of the impeller, the baffle being positioned to further direct the flow of air to the impeller. 2. The apparatus of claim 1, wherein the housing includes a sidewall having a vacuum port and wherein the vacuum port is coupleable to a vacuum source. 3. The apparatus of claim 1, wherein the liquid jet is oriented to form an angle between 80 and 90 degrees relative to a plane in which the impeller rotates. 4. The apparatus of claim 1, wherein the baffle is an upper baffle, and wherein the apparatus further comprises a lower baffle carried by and rotatable with the impeller to further direct the flow of air toward a lower portion of the housing. 5. The apparatus of claim 4, wherein the lower baffle is positioned to direct the flow of air to form an airflow parallel to a plane in which the impeller rotates. 6. The apparatus of claim 1, wherein the baffle is positioned to separate the flow of air from a liquid stream emitted from the liquid jet. 7. The apparatus of claim 1, wherein the baffle has a conic sectional shape. 8. The apparatus of claim 1, wherein the baffle has a rectangular cross-sectional shape. 9. The apparatus of claim 1, wherein the baffle has a cylindrical shape. 10. An apparatus for cleaning a surface with a cleaning solution, the apparatus comprising: a housing having a sidewall, the sidewall having a vacuum port;an air induction port positioned in the housing;an impeller rotatably positioned within a rotation volume below the air induction port;a fluid jet coupled to the impeller to rotate with the impeller and positioned to dispense the cleaning solution on the surface; anda baffle extending circumferentially around the rotation volume, wherein the baffle is positioned to guide a flow of air through the air induction port to the impeller. 11. The apparatus of claim 10, further comprising an inner housing positioned between (a) the fluid jet and the impeller and (b) the vacuum port. 12. The apparatus of claim 10, wherein the baffle is an upper baffle, and where the apparatus further comprises a lower baffle carried by and rotatable with the impeller to further direct the flow of air, and wherein the lower baffle is positioned in a lower portion of the housing. 13. The apparatus of claim 12, wherein the fluid jet is positioned between the upper baffle and the lower baffle. 14. The apparatus of claim 12, wherein the lower baffle includes a portion parallel to a plane in which the impeller rotates. 15. The apparatus of claim 12, wherein the impeller is positioned between the upper baffle and the lower baffle. 16. The apparatus of claim 10, wherein the baffle is positioned to direct the flow of air through the air induction port to form an airflow parallel to a plane in which the impeller rotates. 17. The apparatus of claim 16, wherein the housing has an upper portion and a lower portion, and wherein the airflow parallel to the plane is formed in the lower portion of the housing. 18. A method for manufacturing a surface cleaner, comprising: positioning an impeller inside a housing, wherein the impeller includes a plurality of blades and wherein the housing includes an air induction port and a sidewall, the sidewall having a vacuum port coupleable to a vacuum source;positioning at least one of the plurality of blades adjacent to the air induction port;coupling a fluid jet to the impeller; andconnecting a baffle to the impeller, wherein the baffle extends circumferentially around a rotation volume of the impeller and is positioned to direct a flow of air through the air induction port to the impeller. 19. The method of claim 18, wherein the baffle is an upper baffle, and wherein the method further comprises connecting a lower baffle to the impeller. 20. The method of claim 19, further comprising positioning the lower baffle in a lower portion of the housing. 21. The method of claim 19, further comprising orienting the fluid jet to form an angle between 80 and 90 degrees relative to a plane in which the impeller rotates. 22. The method of claim 19, further comprising: positioning the plurality of blades in an outer portion of the impeller;positioning the baffle to form an airflow parallel to a plane in which the impeller rotates; andorienting the fluid jet to form an angle relative to the plane.
