6. Q: Will long-term charging consume more power? Will overcharging shorten the service life
of the battery?
A: Charging stops after the battery is full. The motherboard is powered directly from the dock
charger and the battery is in standby mode and thus the battery performance will not be affected.
The machine consumes very little power (less than 3 W) when not in use. To maintain the best
battery performance, please try to keep the machine connected to the dock charger when it is
left unused.
7. Q: Why does it take longer to charge in summer?
A: The machine is designed with a charge and discharge management system. In summer, the
battery may be hot immediately after cleaning. To extend the service life of the battery and
ensure charging safety, charging will start only after the battery temperature reduces. Thus, it
is normal that charging takes longer in summer.
User complaints about the charging speed slowing down
(Updated on May 31, 2018)
A: When used at high or low temperatures, the machine will automatically reduce the charging
speed so as to extend battery life. Starting from June 11, the charging time is 5 hours when
used below 16 degrees Celsius, and 10 hours when used below 7 degrees Celsius (for all
models).
8. Q: Why does it fail to power on in winter?
A: Please ensure that the machine operates in an environment with a temperature of no less
than 0°C; otherwise, the machine may not power on so as to protect the battery. This is the
same as the low temperature battery protection mechanism used in iPhones.
9. Q: Will the laser head be damaged due to the interference from a full-length mirror?
A: No. Please rest assured that a full-length mirror will not impact the cleaning operation of the
machine.
10. Q: How long can the machine work for once fully charged?
A: This depends on the operating time, floor material and mode of operation. For a common
floor without a carpet, a fully charged machine can work for about 2.5 hours in Standard mode,
less in Strong mode and longer in Silent mode.
