1. Charging Dock Placement
Place the charging dock against a wall in an open area, ensuring there are no obstacles within 1 meter (3 feet) to the sides and 2 meters (6 feet) in front of the dock. Connect the power adapter to the charging dock and plug it into a wall outlet. Ensure the dock's indicator light is on.

2. Initial Charging
Place the robot onto the charging dock. Ensure the charging contacts on the robot align with those on the dock. The robot will begin charging automatically. For first-time use, charge the robot for at least 5-6 hours until fully charged. A full charge provides over 2 hours of operation.
3. Install Side Brushes
Attach the two side brushes to the designated posts on the bottom of the robot. Press firmly until they click into place.

Depending on your cleaning needs, insert either the dustbin for vacuuming or the water tank with a mop pad for mopping. Ensure it is securely seated in the robot's compartment.
5. Wi-Fi App Connection
Download the Mamibot application from your smartphone's app store. Follow the in-app instructions to connect your PreVac 650 to your home Wi-Fi network. This enables remote control and scheduling features.

Cleaning Modes
The PreVac 650 offers multiple cleaning modes to suit different needs:

Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Mamibot PreVac 650.
1. Emptying the Dustbin
After each cleaning cycle, or when the dustbin is full, remove it from the robot and empty its contents into a trash bin. Clean the filter regularly by tapping it gently to remove dust.
2. Cleaning the Main Brush and Side Brushes
Periodically remove the main brush and side brushes. Use the provided cleaning tool to cut and remove any hair or debris tangled around them. Reinstall them securely.

3. Cleaning the Water Tank and Mop Pad
After mopping, empty any remaining water from the tank. Rinse the tank and allow it to air dry. Remove the mop pad, wash it (hand wash or machine wash according to fabric care instructions), and let it dry completely before reattaching.
4. Cleaning Sensors and Charging Contacts
Wipe the cliff sensors (located on the bottom of the robot) and the charging contacts (on the robot and dock) with a clean, dry cloth. This prevents dust buildup from affecting performance.
