Robot vacuum gets stuck frequently on carpets, thresholds, or under furniture without showing a specific error code.

Safety first: Manually free the robot and power it off if it continues to struggle.

Step-by-step:

• Identify problem spots: Note where the robot gets stuck (specific rugs, thresholds, furniture).
• Use app restrictions: Set no-go zones or virtual walls around problematic areas in the Roborock app.
• Adjust environment: Add small ramps to high thresholds, secure loose rug edges, or raise low furniture slightly if possible.
• Inspect wheels: Check drive wheels for wear or slick surfaces. Replace wheel modules if treads are badly worn.

These adjustments usually resolve frequent non-error-code stalls.
