Abstract
An assembly '(42)' including a fluid levitated caster and a debris scraper '(31)' device positioned external to a levitation membrane '(11)'. Assembly '(42)' levitates heavy loads upon a near frictionless pressurized fluid, and also sweeps aside potentially membrane destructive debris '(25)' from a floor '(27)' in the path of movement. The external debris scraper '(31)' function does not noticeably increase movement friction, and does not require increased power air flow or consumption.
