Vacuum runs for only a few seconds then stops; can be restarted but cuts out repeatedly.

Safety first: Remove the battery before cleaning or disassembly.

Steps to try:

• Deep clean filters: Remove all filters. Tap off loose dust, then wash if the manual allows. Let them dry for at least 24 hours before refitting.
• Clear airflow path: Detach the bin, tube, and floor head. Check each section for blockages and clear them with a long, non‑metallic tool.
• Inspect vents: Ensure the motor housing vents are not covered by dust or lint.
• Test runtime: After reassembly, run the vacuum and time how long it operates. If it still stops within seconds, the thermal sensor or motor windings may be failing and the main body assembly will likely need replacement.
