High rpm The machine runs very loud and sounds like the rpm is to high

It sounds like at least one bearing has dried out and needs replacing.

Issar 702:

Take the machine to a room that has no carpeting, (this is 'gonna get messy :-) First, make sure that the machine is unplugged from the wall, then remove the wand with the hose and verify that the hose, wand and vacuum head are not clogged up... check carefully, some clogs or items stuck in the hose and wand assembly can be hard to find! Then check the hose from end to end making sure that the hose is clear of debris. Then open the canister and check to see that the gasket around the top of the canister is not damaged, then check the belt coming off of the motor driveshaft is not binding or damaged. You should be able to rotate the belt by hand with the machine off and unplugged.

If the noise is continuous from switching on and slows down to a stop when machine is tured of it has to be some thing on contact with the motor or the brush roller the brush roller is easy to check the motor isnt but is less likly to go wrong

It's clogged!
Many so-called "environmentally friendly" vacuum cleaners have multiple stage filters; the usual configuration is a standard filter followed by a HEPA filter or equivalent. Standard filters can be a paper bag or a bagless, removable container.
From time to time, the secondary filter will get clogged, so it doesn't matter whether you change the bag or empty the container, performance will not improve.
If you have access to compressed air, try removing the secondary filter and blowing it clean with a high pressure air nozzle. If that doesn't work, check the hose to make sure it's clear. If you are using a rug beater attachment, make sure it has not clogged at its inlet.

High pitched noise is not good. It may indicate that a bearing is going out. I would not use Kirby as it may lead to burned motor.

If you feel that it vibrates quite a bit too - then it may be only broken fan blade.

Fan blade - you are looking ar around $40-$50 and if this is a motor bearing - $60-$80. If anyone wants to charge you more - we will repair it but you will have to pay shipping both ways (roughly another $30 both ways all together)

Ohhh yeah - try it with the hose. If no sound then brush roll bearings may be bad...

Good Luck,

most likely your bearings are shot. it will need a new motor

The whinning sound may be the bearings are bad. This will have to be taken care of or it will wear your motor brushes down very quickly. It is not generally caused by the filter, but by not be cleaned properly and may have been stored on its water basin.

You may be loosing your bushings on the motor,if this is an expensive machine it may be cheaper to have it fixed,if not it will burn up eventually.Also try taking the beater bar out and make sure you don't have something rapped around it causing a noise.

If it sounds really high pitched or like a airplane i would bet your motor is shot in which case it would exceed cost of your unit.

Hi. Check the carbon brushes they may be breaking down.
