The charging pole piece of the Xiaomi Robot Vacuum S20 is exposed in a complex environment. As the use time increases, normal phenomena such as oxidation and yellowing will occur to varying degrees. This will not affect the charging function, but it needs to be wiped regularly with a dry cloth.
Note:
1. It is recommended to clean the dust box thoroughly at least once a week. Please be sure to dry the dust box before use;
2. The filter can be rinsed with water. Make sure it is completely dry before re-installation. Frequent rinses are not suggested;
3. As long as the charging contacts are not significantly corroded or damaged, they should still function properly.
