Vacuum intermittently turns off when the tube is moved or rotated.

Safety first: Remove the battery before inspecting electrical connectors.

• Step 1 – Reproduce fault: Run the vacuum and gently move the tube. If power cuts in and out, the tube wiring or connectors are suspect.
• Step 2 – Inspect connectors: Check the electrical contacts at both ends of the tube for corrosion or bent pins. Clean and straighten as needed.
• Step 3 – Tube replacement: On most Clatronic cordless vacuums, the wiring inside the tube is not user‑serviceable. Replace the extension tube with integrated wiring.
