Kirby Sentria 2 burning smell (not belt)

Make sure the belt is the right size.. It should be very very tight.

Replace your belt and clean your roller brush.

1. Make sure the belt is in contact with the shaft. 2. Remove the roller and clean the brushes AND the area that seats into the vacuum. If there is too much hair, string, etc. the brush may not roll. chances are the belt is probably not making contact. If it was you would smell rubber burning if the brush wasn't turning.

Check the brush roll to be sure it's spinning free too much drag can cause that to get hotter but usually it would break the belt. That spindle will get hot from the friction created by turning the belt and from the motor's heat. They'll just get hot, any brand that spindle will be hot after running it. It's just how it is.

kirby has a 3 yr back to base guarentee so contact ur local rep or kirby direct and thy will sort it all from there, hope this helps :)

An Ultimate G has lots of suction. If you turn on your vacuum and the bag immediately inflates - that is how you can tell if your Kirby is moving air (suction). There is a more modern brush that came out with the Ultimate G Diamond and the Sentria that has stiffer bristles that dig up pet hair better.

Another way to test the suction is to spread some baking soda onto a hard floor and vacuum it up - you can see how much suction your Ultimate G has, or take off the vacuum head and put on a hose and test the suction at the end of the tube.

Ways to increase your Ultimate G cleaning efficiency. Take off the vacuum head and remove the brush roller. Attach your hose attachment and **** vacuum out the head. Put on a new belt, and remove any hair and or string or threads that may be wrapped around the brush roller. Put the roller back on and on the ends of your roller you will see that the ends spin and have numbers on them. If your vacuum brushroll is original - you could have your bristles rather worn and so you can align the #3 on BOTH sides of the brushroller. This would be a good time to consider upgrading to the Sentria Brush.
Remove the bag, and replace with the CLOTH Kirby bag. It has the best filtration and it has the best airflow (which increases what you are referring to as suction). If you want to go the cheap route - at least get the paper Micron Magic with HEPA filtration (but it has slightly less air flow)
Remove the side mini emptor from the vacuum and check to see if there is anything clogged up on either the vacuum or the mini-emptor.
If your engine is running and inflating the bag and you replace the belt, the brush roller and to the cloth dust bag - your vacuum should pretty much run like a brand new Sentria Vacuum. Your vacuum system is outstanding, but may benefit from a little TLC if you have been neglecting it.

The belt driving the brush roller in the power head is slipping. It is really just a big thick rubber band. Where it wears out it slips and burns due to friction.

Look at the bottom of the power head. There is a cover plate held with 2 to 4 screws. Remove the plate and you will see the roller and drive belt. Slip the roller out and remove the belt.

Go to your local vacuum dealer and get a replacement.

Installation is the reverse of removal.

If it is a smell of burning rubber - most likely your vacuum belt is overdue for replacement.

At this point - remove the brush roller, remove the old belt, clean off your brush roller and remove any string or hair that may be bound up around it (usually around where the belt goes or on the sides), and put on a new belt. Your Kirby should act good as new if your bag is replaced at the same time.

If the brush roller has too much string and hair wrapped around it, many times the brush roller will not spin as fast as the belt is driving it and you will get that burning smell.

sounds about right you should change that type of belt every six months to a year regardless if its broken or not. one other thing you should do is make sure the brush roll itself isn't bound up it should spin freely if not you can pull the plastic ends off the roller to clean any hair or thread out .

Yes, replace the brush roll, the ends or end is probably bad and causing the belt to slip and burn up.
