HOW THE MACHINE WORKS

The steering wheel controls the direction of machine travel. The directional pedal controls the speed and forward/reverse direction. The brake pedal slows and stops the machine.

The side brush sweeps debris into the path of the main brush. The main brush sweeps debris from the floor into the hopper. The vacuum system pulls dust and air through the hopper and the dust control system.

The machine also has a wet side brush dust control option to help contain dust.

The machine also has an optional dry sweeping

HEPA filtration system to help contain fine dust.

When sweeping is finished, shake the dust filter and empty the hopper.
