The Hoover H-GO 300 HYDRO is a 2-in-1 robot vacuum and mop. Before first use, charge the device for at least 8 hours. Ensure the charging station is placed against a wall on a non-reflective floor with 2 meters of clearance in front and 1 meter on each side. Always remove obstacles like cables, fragile objects, and floor-length curtains before starting a cleaning cycle.
Getting to know your cleaner
The robot features a front bumper, dust container, and various sensors. The remote control allows you to set the time, schedule cleaning, adjust suction power, and select cleaning modes. The robot includes side brushes (labeled L and R) and a water tank for mopping.
Preparation and charging
To prepare the robot, install the side brushes until they click into place. Connect the charging station to the mains power adaptor. During normal use, the robot takes 4-5 hours to recharge. When the battery is low, the robot automatically returns to the charging station.

Cleaning modes
The robot offers several cleaning modes selectable via the remote control:
- Auto: Automatically chooses the best cleaning mode.
- Parallel: Systematic cleaning pattern.
- Spot: Intensive cleaning of a confined area in a circular path.
- Edge: Cleans along walls and around furniture.
- Manual: Controlled using the arrow buttons on the remote.
Mopping function
To use the mopping function, fill the water tank with water (and optional cleaning agent), attach the mopping cloth, and click the tank into the bottom of the robot. Warning: Water may drip as soon as the tank is inserted, so start cleaning immediately. Remove the tank when charging or not in use.

Maintenance
Regular maintenance is essential for performance:



- Dust Container: Empty after every use.
- Filters: Clean the pre-motor and sponge filters every 5 dust container empties. Do not wash.
- Sensors: Clean the anti-fall sensors on the underside with a soft brush.
- Brushes and Wheels: Regularly remove hair and debris from the agitator, side brushes, and drive wheels.
