Thus, it is normal that charging takes more time in summer.
7. Q: Why does power-on fail in winter?
A:
Please ensure that the machine operates in an environment with
temperature not less than 0°C; otherwise, the machine may be impossible
to be powered on to protect the battery. In this regard, it is the same as the
battery protection mechanism in low temperature used in Apple phones.
8. Q: How long can it work in full charge state?
A:
The operating time depends on floor material and mode of operation.
For a common floor without a carpet, E5 in full charge state can work for
about 6 hours. The operation time can be shorter in Strong mode or Max
mode and longer time in Silent mode. E5 support the breakpoint
continuation function. The machine will automatically return for recharge
when the battery is lower than 20%, and go back to the breakpoint to
continue cleaning when charging to 80%. Even large-size houses can be
fully covered.
9. Q: Is electric motor overload protection mechanism available?
A:
All electric motors are provided with a motor overload protection
mechanism, including side brush motor, main brush motor, main wheel
motor, and vacuum cleaner fan motor.
10. Q: What's the RPM of the side brush, main brush and fan?
A:
The side brush can be dynamically regulated and works at 330 RPM
along a wall and 130 RPM in other conditions. The main brush works at
1350 RPM, while the vacuum cleaner fan of E5 works at 12000 RMP in
Standard mode.
11. Q: What kind of lithium battery is used and what's the capacity?
A:
The rated voltage is 14.4V.
Uses 8 high-quality 18650 lithium
batteries with the capacity of 5200mAh.
