Abstract: A floor treatment apparatus is provided that includes a chassis that supports at least one cleaning element. The chassis is supported by a plurality of wheels, one which is steerable via a steering wheel interconnected to a housing also associated with the chassis. The chassis provided includes a plurality of movable housing members, one of which is associated with the steering wheel. To access the internal components of the floor treatment apparatus, the front housing is rotated or moved away from the other housings wherein the steering wheel does not require disconnection to allow this movement.

Abstract: The present invention relates to a system of creating and applying a heated cleaning fluid to a surface. The system includes a housing with a first, a second and a third exhaust gas opening. A first, second, and third heat exchanger are enclosed within the housing. The first and second exchangers are serially arranged, while the third is at an angle relative to the first and second and directly adjacent to the first opening. Super heated exhaust gas flows through first opening and third exchanger. Heated gas flows through the second opening and passes below the third exchanger. Super heated exhaust gas exiting the third exchanger mixes with the heated gas in a mixing chamber of the housing, which is then supplied to the first and second exchangers. Fluid passes through the three exchangers and exits the third exchanger heated. That heated fluid passes to a cleaning wand for application.
