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 surfaces, comprising: a housing having at least one air induction port traversing the housing;a rotating coupler;an impeller coupled to the rotating coupler;at least one fluid jet coupled to the rotating coupler;wherein rotation of the impeller by a flow of air through the at least one air induction port causes the rotating coupler and the at least one fluid jet to rotate; andwhereina baffle carried by and rotatable with the impeller and extending circumferentially around a rotation volume of the impeller, the baffle being positioned to further direct the flow of air to said impeller. 2. An apparatus for cleaning a surface, comprising: a housing:a rotating coupler coupled to the housing;an impeller coupled to the rotating coupler and 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 cause the impeller to rotate;a liquid jet coupled to the rotating coupler and 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. 3. The apparatus of claim 2, wherein the housing includes a vacuum port coupleable to a vacuum source. 4. The apparatus of claim 2, wherein the liquid jet is oriented to form an angle between 80 and 90 degrees relative to a plane in which the impeller rotates. 5. The apparatus of claim 2, 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. 6. The apparatus of claim 5, 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. 7. The apparatus of claim 2, wherein the baffle is positioned to separate the flow of air from a liquid stream emitted from the liquid jet. 8. The apparatus of claim 2, wherein the impeller includes a plurality of blades circumferentially positioned adjacent to the air induction port. 9. An apparatus for cleaning a surface with a cleaning solution, the apparatus comprising: a housing having a vacuum port;an air induction port positioned in the housing;an impeller rotatably positioned 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;an upper baffle carried by and rotatable with the impeller and extending circumferentially around a rotation volume of the impeller, wherein the upper baffle is positioned to guide a flow of air through the air induction port to the impeller; anda lower baffle carried by and rotatable with the impeller to further direct the flow of air. 10. The apparatus of claim 9, further comprising: an inner housing positioned to separate the fluid jet and the impeller from the vacuum port. 11. The apparatus of claim 9, wherein the lower baffle is positioned in a lower portion of the housing. 12. The apparatus of claim 9, wherein the lower 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. 13. The apparatus of claim 12, 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. 14. The apparatus of claim 9, wherein the fluid jet is positioned between the upper baffle and the lower baffle. 15. The apparatus of claim 9, wherein the lower baffle includes a portion parallel to a plane in which the impeller rotates. 16. The apparatus of claim 9, wherein the impeller is positioned between the upper baffle and the lower baffle. 17. A method for manufacturing a surface cleaner, comprising: forming an air induction port in a housing;forming a vacuum port in the housing, wherein the vacuum port is coupleable to a vacuum source;coupling rotating coupler to the housing;positioning an impeller inside the housing, wherein the impeller includes a plurality of blades;coupling the impeller to the rotating coupler, wherein at least one of the plurality of blades is positioned adjacent to the air induction port;coupling a fluid jet to the rotating coupler, wherein the rotating coupler is coupleable to a fluid source; 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. 18. The method of claim 17, wherein the baffle is an upper baffle, and wherein the method further comprises: connecting a lower baffle to the impeller. 19. The method of claim 18, further comprising: positioning the lower baffle in a lower portion of the housing so as to direct the flow of air to form an airflow parallel to a plane in which the impeller rotates in the lower portion of the housing. 20. The method of claim 17, further comprising: orienting the fluid jet to form an angle between 80 and 90 degrees relative to a plane in which the impeller rotates. 21. The method of claim 17, further comprising: positioning the plurality of blades of the impeller;positioning a lower baffle in a lower portion of the housing so as 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.
