Roborock Customer Service Center - Technical Support
has the output voltage of DC 4.2V which is far less than 36V, the safe
voltage for human body; finally, please be assured that the dock charger is
provided with short circuit and current leakage protection features such
that it can be automatically powered off in abnormal situations.
21. Q: Why does the robotic vacuum cleaner neglect some locations (for
example, the 2cm balcony with black floor is neglected)?
A:
1. The machine may regard the dark floor or carpets with good light
absorption ability as a cliff that it should avoid. Therefore, they are not
cleaned.
2. If there is dust on the cliff sensor, the cliff sensor may be wrongly
triggered for non-dark floors. Please use soft & dry cloth to carefully
clean the 4 cliff sensors on the bottom of the machine and then try again.
3. The area around the dock charger is the anti-collision restricted area,
which is specially designed to prevent the machine from being twined by
the power cable of the dock charger or hitting the dock charger.
Therefore, the machine will automatically avoid this area instead of
cleaning it.
22. Q: What is the sound level of the robotic vacuum cleaner?
A:
When measuring at 1m away, the sound level is between about 60 and
66 dB. It may have a slight difference depending on machine model.
23. Q: How long will the robotic vacuum cleaner take to charge?
A:
It will be fully charged from empty in about 3.5 hours.
24. Q: Will tire's trace be left on the floor behind the robotic vacuum
cleaner?
A:
The tires of the robotic vacuum cleaner are made of flexible materials
and on the bottom of the main brush is a cushion rubber; in addition, the
face of the omni-directional wheel is also made of flexible materials. The
machine has the total weight of 3.0kg and thus will not scratch the floor
in normal use condition.
