Setup

1. Unpacking and Initial Assembly

Carefully unpack the machine and its components. This video demonstrates the unpacking process, connecting the battery, installing the squeegee assembly, and attaching the vacuum hose. It also shows how to install the brush tray and pads.

2. Battery Connection

Access the battery compartment (under the sewage tank) and connect the battery cables. Ensure a secure connection.

3. Squeegee Assembly Installation

Attach the squeegee assembly to the rear of the machine. Ensure the suction hose is securely connected to the squeegee's connection point and tighten the bolts on each side. Adjust the squeegee height as needed.

4. Brush/Pad Installation

Place the desired brush or pad directly under the brush tray shield. Step on the brush lifting pedal to lower the brush cover and automatically load the brush/pad. To remove, depress the pedal and move the machine slightly to the left to disengage. Rotate the brush disc counter-clockwise to detach.

5. Filling the Water Tank

Open the freshwater tank cap and fill with clean water. For optimal cleaning, add a neutral pH low-foam cleaning solution. Do not overfill.
