1. Please check whether the packaged product is intact after receiving the vacuum cleaner. If there is any damage, please contact customer service as soon as possible.
2. After checking that there is no damage, first charge the vacuum cleaner for 3-4 hours (ignore the charging light), and then try to turn on the vacuum cleaner. Please do not use the vacuum cleaner while charging
3. Check whether the filter is installed correctly before use. If the filter is not installed properly, the liquid will follow the fan blade and enter the body when absorbing water.
4. Do not let the battery part of the vacuum cleaner touch water, which will cause it to fail to charge.
