Turn off the vacuum cleaner switch, unplug the charger TYPE-C plug
from the socket, and then clean the body.
Kind Note：Do not expose the vacuum cleaner to extreme climatic
environments (such as rain, high temperature and other extreme
environments).
If necessary, use a dry cloth to clean the body, dust, filter frame and
accessories
Make sure that no liquid flows into the vacuum cleaner. Do not put its
parts in the washing machine for cleaning.
Do not use abrasive cleaners (detergents, thinners) because they will
damage the synthetic surface of the body.
Ensure that all parts of the vacuum cleaner are completely dry before
inserting the charger plug into the hole.
How to clean the ash storage cavity and filter rack
After each use, the ash storage cavity should be emptied and cleaned
up. When the ash storage chamber is full of dust, it is recommended to
dump it as soon as possible. This will prevent dust from flying out.
When cleaning the vacuum cleaner, separate the charger from the
vacuum cleaner.
