FAQ
  • Q
    Why is there noise for a few seconds after the appliance is powered off?

Troubleshooting
There is water leaking onto the floor from the cleaning head when moving forward.
2026-09-15

The most likely cause of this issue is that the Waste Water Tank lid is not installed tightly, which can result in weak suction, preventing the waste water from being drawn into the tank. Simply reinstall the Waste Water Tank lid and press it into position.

The cleaning head turns left or right without twisting the F300.

Please check if the wiper is cracked. Usually, if the wiper is cracked and blocks the Multi Roller, it will cause the head to turn to one side.

Why does water leak onto the floor or into the Solid Waste Container when mopping?
2026-09-15

Water leakage is usually caused by a blockage in the waste water tube.

1.Remove the Multi Roller and take out the metal filter. Wash and clean the water-squeezing bar and the metal filter.

2.Face the cleaning head and locate the release button on the left side. Press it to remove the left-side cover. You will find a transparent waste water tube cover and a rubber comb filter. Remove them and rinse under tap water to clean. Perform this cleaning once a week to prevent blockages that could cause water leakage.
