The Vacuum Cleaner is an ubiquitous piece of equipment in any home. Given the right care, it lasts for a long time. A typical dry type Vacuum Cleaner has few parts to go wrong other than its motor. And the motors in them are not subjected to overloads as are other motors doing duty elsewhere. Here in this page, we present actionable tips on the maintenance of the Vacuum Cleaners.
If the Vacuum cleaner refuses to run, first check for frayed wires feeding it. If you have a VOM (Volt Ohm Meter) - a simple digital multimeter set to continuity tester mode when connected across the mains plug of the unit will tell you if the motor, wires and the switch are normal when it shows a reading of 20 Ohms or less. If there is no continuity, a good place to start is the switch on the body of the cleaner. Mechanical switches are prone to failure after a few thousand operations. Replace as required.
Some motors may have a thermal fuse on its body. Most manufacturers attach a sheet of the circuit diagram on its inner panel. Look for a thermal fuse if there is no continuity in the motor's terminals.
Typically a Vacuum cleaner intended for home and car will have about 1000 or 1250 W motor with about 12-15 liters dry capacity and if wet type, it may have about 14-18 liters capacity. They may have a noise rating of 80-85 dB. Most Vacuum cleaners use high speed universal motors which can rotate at several thousand rpm (rotation per minute). They use carbon brushes which require periodic replacements. This is a job best left for the qualified service technician. Do not disassemble the motor section of the unit under any circumstances unless you know what you are doing.
As we have mentioned in this series of articles on home maintenance, a lay user can only attend to general maintenance with limited skills and tools. All electrical and electronic machines operate at lethal voltages and can CAUSE serious damage or shock hazard to self and home. It is positively dangerous to even attempt to repair any electrical machines without the required skills or knowledge. Always refer servicing to qualified technicians or the dealer.
