The Advance 2800 ST and 3400 ST scrubbers deliver high performance results on a back-to-basics rider-scrubber platform. Manual control of the scrub deck and squeegee replace intricate electronics to keep operation simple without sacrificing performance. When your job calls for scrubbing large spaces at a lower total cost to clean, Advance's ST scrubbers are a smart choice.

Simplified mechanics and design make operation easy, and help keep the cost of ownership low. An open operator compartment allows cleaners to get on and off the machine from either side and provides clear sight lines to the floor. To start, scrubbing, just manually lower the scrub deck and squeegee and press the foot pedal. Training is easy for operators of all experience levels, and minimal adjustments are required while using the machine.

Available in 28 or 34 inch disc scrubs decks, the ST rider-scrubber are proof that you don't need a complex machine to get clean floors. The calibrated low-solution-flow setting provides 85 minutes of run time on a single tank, for consistently clean results on moderately soiled floors. For high traffic areas, operators can increase the solution flow rate at the touch of a button and apply more down pressure, for more aggressive cleaning.

A host of additional features rounds out the superior performance and convenience you look for in a rider-scrubber. Choose either wet-acid or AGM batteries with a stand-alone charger. The steering wheel is adjustable tools-free to provide additional operator comfort to the spacious operator compartment. And at a low operating sound level of just 66.7 dBA, ST scrubbers are quiet enough for daytime cleaning.
