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. 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. 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. The patented Safe ‘N Dry[TM] squeegee system uses a perforated squeegee to remove the collected water under the squeegee and allows for 100% water pick-up for safe, dry floors.
