27. Q: Is it normal that the side brush and bottom cover are scratched?
A: During use, the side brush may become deformed upon collision with an obstacle or the
bottom cover may become scratched. This is a normal sign of use and will not impact product
performance.
28. Q: Is the upper cover of the machine strong enough not to be easily broken?
A: Both the upper cover and its joints are made of resilient materials. The upper cover cannot
be easily broken unless malicious damage is caused.
29. Q: Is the upper cover wear-resistant?
A: In-Mold Decoration by Roller (IMR) technology is used for the upper cover such that the
surface is very smooth and flat and will not be scratched except in the case of malicious damage
such as the use of a hard or pointed object.
30. Q: What should I do when the laser head protective cover of the machine is stained?
A: As this is the highest point of the machine, it is hard to avoid it being scratched underneath
furniture, but please note that this will not impact the machine's performance. If you are
particularly concerned about this, you can make some circular protective films to stick on it.
31. Q: What's the black soft rubber ring on the dust bin and what's its purpose?
A: The black soft rubber ring on the dust bin is an FIP seal ring that has the advantages of being
both tightly sealed and dustproof. The dust bin is closely mated with the air ducts on both sides
with the help of the FIP seal ring.
32. Q: Why is only one side brush provided rather than two?
A: Firstly, the side brush of the robotic vacuum cleaner is mainly used to clean waste along a
wall or at the base of an obstacle. The side brush is not a main cleaning structure when cleaning
other areas. For example, for non-edge cleaning, if the side brush always runs at high speed,
it may make the waste fly about. The side brush can be dynamically regulated and the speed
of the side brush will be reduced for non-edge cleaning to prevent waste flying about. Secondly,
the machine is designed in such a way that only one side cleans against a wall or the base of
an obstacle, so a side brush is not required on the other side. Finally, if the machine were to
