Charging your machine
For the best experience, we recommend fully
charging your machine, and any additional
batteries, as soon as you open the box and
after every clean. This is because the battery
and monitoring system's algorithm 'learns' over
time, and fully charging your batteries helps
it to more accurately calculate and display
remaining run time.
Connect the charging cable directly to your machine
or into the dock.
The blue LEDs on either side of the battery will flash
as your machine charges and the LCD screen will show
a full battery icon when fully charged and ready to use.
Your machine won't operate or charge if the ambient
temperature is below 5°C (41°F). This is designed to
protect both the motor and battery.
You can help prolong the battery life by leaving your
machine to cool down before recharging.
Changing your click-in battery
If you have additional click-in batteries, we
recommend that you alternate the batteries to
maintain even performance.
