If your S2 robot leaves dust or dirt along edges or in corners during cleaning or mopping, follow the troubleshooting steps below to improve edge cleaning performance and accuracy.

Step 1: Check Corner Width

• The robot can only clean areas wider than 36 cm.

• Very narrow spaces or tight corners may be missed because the robot cannot physically access them.

Step 2: Clear Objects Near Edges and Walls

• Remove small objects or obstacles near walls and corners before cleaning.

• This step allows the robot to maintain smooth contact and consistent edge cleaning.

Step 3: Consider Carpet Cleaning Effects

• High-friction carpets may cause the side brush bristles to bend or deform, reducing edge cleaning efficiency.

• For better results, perform multiple cleaning passes over carpeted edges.

Step 4: Maintain or Replace Accessories

• Long-term use without maintenance of components like the roller brush, side brushes, or dustbin can reduce cleaning efficiency.

• To check maintenance status and perform cleaning or replacement:

•   Settings → More Settings → Accessory Services

Step 5: Test Edge Cleaning Using Zone Clean

• If certain edges or corners are consistently missed, use the Zone Clean feature to target these areas directly.

• Observe whether the robot can clean them properly within the defined zone.

Step 6: Consider Material and Color Recognition

• Dark, black, or transparent surfaces may interfere with the robot’s edge detection sensors.

• This step can cause the robot to maintain a longer distance from walls or corners.

• Adjust lighting conditions or increase cleaning frequency for these areas if needed.

Step 7: Check Kitchen Cabinet Clearance and Structure

• Built-in or recessed cabinets may be difficult for the robot to clean thoroughly:

• The S2 robot’s side extension reaches up to 15 mm; recessed areas deeper than this cannot be cleaned effectively.

• If the cabinet clearance height is below 12 cm, the robot will automatically skip the area for safety.

• Adjust settings to allow the robot to explore areas with limited clearance:

•     Settings → Cleaning Preference → Height Detection Sensitivity → Medium Mode
