An apparatus (100) for cleaning solid surfaces includes a housing (110) configured to substantially encapsulate a surface being cleaned, a vacuum port (120) traversing the housing (110), a high speed rotating coupler assembly (130) rotatably coupled to the housing (110), a plurality of impeller blades (150) coupled to the high speed rotating coupler assembly (130), at least one fluid jet (140) coupled to the impeller blades (150), and at least one air pathway (160, 120)configured to pass input air past the impeller blades (150) to rotatably drive the impeller blades (150).
