Wyze robot vacuum's front bumper feels loose or misaligned, and collisions are not detected properly.

Safety first: Turn off the robot before manipulating the bumper.

• Check bumper movement: Press the bumper along its length. It should move in and out smoothly and evenly.
• Clear debris: Use compressed air or a thin plastic tool to remove debris from the gap between the bumper and body.
• Inspect for cracks: Look for visible cracks or broken plastic around the bumper edges.
• If bumper remains loose or uneven: Internal springs or guides may be broken. Repair requires removing the top cover and bumper assembly to replace or reseat components; this is a moderate to advanced repair.
