Vacuum cleaner — symptoms, diagnosis and maintenance
Suction depends mainly on an unobstructed airflow path, filters and sealing. Overheating or an electrical smell requires switching the appliance off.
Safety rule: stop when there is smoke, sparking, a burning smell, electric-shock signs, an active leak, cracked hob glass or suspected gas. Disconnect only when it is safe to do so.
