Abstract: A motor-driven, fixed or adjustable spray system is provided, in which the motor overrides and augments the natural rotational force supplied by the input water pressure through one more inclined spray nozzles, thereby increasing the strike force and efficient water impacting of the floor surface. This enhances water delivered from one or more nozzles to impact into the floor surface such as cement, tile, pebble-reinforced concrete, patio stones, linoleum and the like and thereby dislodge various contaminants compared to conventional floor cleaning systems. The spray system may be adjustable from about horizontal to vertical and is also adapted to utilize cleaning pads such as from fibers, cloths, abrasive pads, etc. Use of the cleaning pads may also be augmented by the water spray. Rotary movement of the spray system and/or the cleaning pads may be effected by electrical power, including battery power, or by an equivalent pneumatic (i.e., air driven) power, hydraulic power, etc.
