Extension tube or joints wobble excessively, making the vacuum feel loose and unstable.

Safety first: Remove the battery before inspecting structural parts.

• Inspect the locking tabs and slots at both ends of the extension tube for wear or cracks.
• Check the mating connectors on the main body and floor head for damage.
• If the tube does not lock securely, replace the extension tube.
• Do not use the vacuum as a lever or to push heavy objects; this can damage joints.
