The cleaner should be charged every three months if it needs to be stored for a long
time. Please use the original and authorized adapter only to ensure that the battery power
is maintained at 40%-60%. The battery voltage will be lower than the over-discharge
protection voltage due to the self-discharge of battery if not charging the battery for a long
time, which will lead to fatal damage to the battery if continuing too long. Please be
careful.
19.
Prohibit charging the battery under the condition of fire or extreme heat. Do not use or
store the cleaner near the heat source.
20.
Prohibit piercing the cleaner shell with nails or other sharp objects, and prohibit
hammering, impacting and throwing the cleaner.
