Please refer to the following common causes and solutions if your S1 Pro's suction power has diminished.

1. The robot's dust inlet may be blocked.

• Cause: The side brush, roller brush, dustbin, and high-performance filter inside the dustbin may have residual debris blocking the dust inlet.
• Solution: Carefully clean the residual debris from the side brush, roller brush, dustbin, and high-performance filter inside the dustbin.

2. The brush guard strip or filter in the dustbin may be damaged.

• Cause: The brush guard strip may be either damaged or missing, or the foam seal at the dustbin outlet may be damaged.
• Solution: Check if the brush guard strip is intact; if it is damaged or missing, please replace it as soon as possible. Also, please inspect the dustbin outlet's foam seal to ensure it is not damaged.
