10. Q: How often should the side brush and main brush be replaced?
A: The frequency of replacement may vary with service condition and home environment. In
general, the side brush and main brush should be replaced every 3-6 months and 6-12 months
respectively.
11. Q: How do I remove the filter to clean it?
A: Push the buckle on the left of the filter and forcedly rotate to remove it. The removed filter
can be cleaned using a vacuum cleaner, or rinsed with tap water. Dry it thoroughly before use
again.
13. Q: How do I clean the omni-directional wheel?
A: Turn the machine over and pinch the wheel upwards to pull it off. You can also use tools to
gently pry it off from one side. After cleaning, please put it back and press it down to secure it.
(Note: the base of the omni-directional wheel can be removed with an external device)
14. Q: What should I do when the main brush is deformed due to entangled thread?
A: After removing the thread, allow the machine to work for a few times. The deformed rubber
sheet and bristles will slowly return to their normal shape due to centrifugal force. This problem
generally requires no special treatment. The main brush can be replaced if necessary.
