Dust bin door will not close properly or pops open during use, causing loss of suction.

Safety first: Remove the battery before adjusting the dust bin.

• Clean latch area: Remove any dust or debris from the latch and hinge using a dry brush.
• Inspect latch hook: Check for cracks or missing pieces on the plastic hook and catch.
• Close firmly: Press the door closed until you hear a clear click. Ensure no filter or gasket is obstructing closure.

If the door still will not stay closed or opens under suction, the dust bin assembly should be replaced to restore proper sealing and safety.
