Nilfisk Auto SCRUBBER 3400 ST RIDER




When the job calls for scrubbing large spaces at low cost, Advance’s ST rider scrubbers are a smart choice. Advance 2800 ST and 3400 ST scrubbers deliver high performance in a back-to-basics rider platform. Manual control of the scrub deck and squeegee replace intricate electronics for simple operation without sacrificing performance.

Simplified mechanics and design make operation easy. The open operator compartment provides clear sight lines to the floor. To start, just manually lower the scrub deck and squeegee and press the foot pedal. Training is easy, and minimal adjustments are required while using the machine.

Available with 28- and 34-inch disc scrub decks, the ST rider scrubbers are proof 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 tools- free adjustable steering wheel provides additional comfort in the spacious operator compartment. And at a sound level of just 66.7 dB A, ST scrubbers are quiet enough for daytime cleaning.
