Frequently Asked Questions - HRVC-MAI52BK Heinner

Why won't my robot vacuum recharge?

Ensure the robot is making contact with the charging contacts on the base. Place the robot 1 meter in front of the charging base and press the recharging button. Also check that the charging base is plugged in and the contacts are clean.

Why doesn't the robot return to the charging base?

The charging base may be improperly placed. Place it on a level surface free of obstacles. Ensure the robot is not trapped or entangled. If the battery is too low, manually place the robot on the base.

What should I do if the robot gets stuck?

Remove any obstacles like cords or loose objects from the floor. Check if the side brush or main brush is stuck and remove any tangled debris. Restart the robot on a flat surface.

Why does the robot return to charging before cleaning is complete?

The battery level may be running low. The robot automatically returns to recharge when the battery is low. Let it charge fully and then resume cleaning.

How do I set up scheduled cleaning?

Use the smartphone app to set a cleaning schedule. Ensure the robot is connected to Wi-Fi and the 'Do Not Disturb' mode is not interfering with the scheduled time.

The robot is not moving or it moves backward. What's wrong?

Check that the robot is placed on a flat surface (wheels not suspended). Clean the front bumper and cliff sensors if they are dusty. Also ensure the protective cover of the navigation module is not stuck.

Why is there no sound from the robot?

The sound may be muted in the app or the robot may be in 'Do Not Disturb' mode. Check the volume settings in the app and disable 'Do Not Disturb' mode if needed.

How do I connect the robot to the app?

Press and hold the power button for 3 seconds to enter network pairing mode. Follow the app instructions to connect to your Wi-Fi network (2.4 GHz). Ensure your phone is connected to the same network.

How often should I clean or replace the brushes and filter?

Clean the main brush and side brushes weekly. Replace main/side brushes every 6 months. Clean the filter weekly and replace every 1-3 months. For best performance, follow the maintenance schedule.

Can I use the mopping function with detergent?

No, only use cold water in the water tank. Do not add hot water or detergent, as it may clog the system. The mopping cloth can be washed with water and dried thoroughly before reuse.
