The CleenSweep System from Keith Manufacturing Co. is an automated cleanout solution that helps wood processing operations safely and efficiently remove residual materials such as wood shavings, sawdust, mulch, and chips from Walking Floor trailers. Powered by the same hydraulics that drive the Walking Floor unloading system, the CleenSweep tarp travels smoothly along the trailer interior, sweeping remaining material toward the discharge point to deliver thorough, repeatable cleanout without requiring operators to enter the trailer.

By reducing manual labor, preventing cross-contamination between loads, and improving turnaround time, the company says the CleenSweep System offers a safer, more reliable, and productivity-boosting solution for mills, biomass operations, and wood product haulers.

The CleenSweep winch is engineered to adapt to a wide range of trailer configurations. During unloading, the tarp travels smoothly along the inside of the trailer, sweeping residual material toward the discharge point for consistent, thorough cleanout. Once the load is discharged, operators simply retract and reset the tarp at the push of a button, saving time and supporting faster route cycles.
