What to do if the Xiaomi Robot Vacuum S20 gets stuck while cleaning?

When the main unit is cleaning, slippers, plastic bags and other debris at home will get stuck. After solving the stuck problem, try to place the main unit in a nearby cleaned area and continue cleaning. Please try to clear away the debris in your home before cleaning to avoid the main unit getting stuck during cleaning.
When the main unit is cleaning, when it encounters the bottom of furniture that is close to the height of the main unit, the upper surface of the main unit will get stuck. Please set up a virtual wall to prevent the main unit from entering again.
