The Cleansweep system is a tarp that fits against the front bulkhead. Since part of the tarp is beneath the load, it moves with the load when the moving floor trailer is unloaded. This way, no residues of the load are left on the moving floor after unloading and the driver does not need to sweep it afterwards. This prevents contamination of the load and saves the driver a great deal of time. Once the walking floor trailer has been unloaded, the tarp automatically winds back into its place with the aid of a spool on the front bulkhead.
