Centra Supply BBB Business Review

General Overview

The DX20C is a powerful, traction driven walk-behind cylindrical brush scrubber designed for deep cleaning performance in high-demand environments. Featuring dual 20” cylindrical brushes aligned in parallel and supported by an integrated dust collection hopper, the DX20C delivers exceptional cleaning results with productivity rates of up to 24,000 square feet per hour.

Built on the same durable frame as the trusted DX20T rotary model, the DX20C is powered by a robust 24V 125Ah AGM battery pack, offering up to 4 hours of continuous runtime. Its cylindrical brush system allows for debris pickup and scrubbing in a single passβ€”ideal for facilities requiring thorough cleaning across a variety of surfaces including VCT, LVT, LVP, tile, and composite flooring.

The machine supports a wide selection of brush types and stiffness levels, making it adaptable to a range of commercial and industrial floorcare needs. With its simple controls, ergonomic design, and advanced dust collection, the DX20C is a smart solution for maximizing cleanliness, productivity, and operator ease in any deep-cleaning application.
