How to Identify and Fix Common Vacuum Problems ?

The most common problem with a vacuum cleaner is also the easiest to remedy: clogs in the hose or attachments. Also the electrical cord, motor, switch, fan, brushes, and motor bearings can all need repair or replacement.
The most common reason for vacuum motors failing is overheating. Most `dry` vacuums have a flow-though motor. These motors use the air they have sucked up the dust with, to cool themselves. When there is a blockage, flow-though motors are unable to cool themselves due to the lack of airflow.
If all you hear from the vacuum unit is a click at the when you try to start the vacuum motor from inside the house, then the motor in the unit is dead and has to be replaced. A strong odor from the shellac, which coats the copper coil windings, is an indicator that the motor is about to or has burnt out.
As a general rule, if the repair is going to cost less than half the cost of a new vacuum cleaner, it`s best to go ahead and get it repaired. When the service tops half the price of a new machine, it`s probably best to invest in a newer model.
A universal motor is typically used as suction motor across vacuum cleaners. The universal motor is a series DC-motor that is specially designed to operate on alternating current (AC) as well as on direct current (DC).
The suction motor creates vacuum pressure and suction by rotating a motor fan. The impeller rotates at an incredibly high speed of about 30,000 to 35,000 RPM. A suction motor`s power is measured by multiplying the rate of air flow and the vacuum pressure, which induces air flow from the brush through the hose.
On a few, you can replace brushes with the motor in place, through a hole in the side of the endplate. On all inertia starters with face-type commutators, brushes can be replaced without removing the armature /commutator. On a pre-engaged starter, the built-in solenoid is removed (See Stripping the starter motor ).
A worn brush can result in a damaged or destroyed armature as well, which will cost you significantly more than a new carbon brush. By instituting some quick, regular check-ups, you can replace brushes before they cause problems.
Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.
UNITS THAT EMPTY FROM THE TOP: The motors are on the bottom of the vacuum unit. Remove the unit from the wall, turn it upside down, and open the bottom or bottom section to reveal the motor. Each motor has two or three wires that may run to other wires, relay, or mini-breaker.
Durability & Warranty – If you`re looking for a vacuum cleaner with durability and longevity, look no further than Miele. Miele vacuum cleaners are designed and tested to last for 20 years. Miele vacuum cleaners come with a 7-year warranty on the motor and a 1-year warranty on parts and labor.
With the exception of top-of-the-line brands, most vacuum cleaners have a lifespan of about four to six years. While not all machines will need to be replaced after four years, it`s a good indication of when you may need to think about investing in a new one.
Rebuilt Vacuum Pumps offer value and quality at a price considerably lower than purchasing a brand new pump. Our reconditioned vacuum pumps go through a rigorous decontamination and rebuilding process to make sure you are getting a reliable pump that you can count on.

All suction motors, except for the very small battery operated motors, are universal type motors since they can operate with either AC (alternating current) or DC (direct current) power sources. Typically they are designed for best performance with AC at the normal household voltage.
