Scenario Explanations:
Machine spits trash back out during cleaning at the bottom of the pool
Annotation:
1. Invite the user to describe the specific scenes of garbage spitting back (which scenes appear when the machine turns/turns around/touches the wall, from which position it spits out, whether it's the suction port or the door of the silo, etc.)
2. Invite the user to provide photos or videos, then feedback to the technical team for confirmation.
Possible reason：the dust box extension does not fit, please invite the user to lift the dust box cover and take a photo, if the gap is big, we can replace the dust box for the user.
