Innovative features include a simple, ergonomic handlebar and control panel for all scrub functions. And convenience features, like the rear solution tank port that permits filling the solution tank while dumping the recovery tank to save time; the easy-to-ready solution level sight gauge, that tells how much solution is left in the tank; and hands-off brush mounting and removal to avoid getting down and reaching under a machine. All these features help save time with set-up, clean-up and production time.
The scrub brush(es) float over uneven floors, and are gear-driven for optimum scrubbing speed and torque. Maneuvering is a breeze with the center drive wheel that can pivot on corners while the squeegee follows the scrub path.
Advance Convertamax scrubbers have the durability the Advance brand is known for. You can depend on the these scrubbers being productive for a long time.
