I have a Kirby G series diamond edition. There seems to be no suction when I turn on the vaccum. The bag inflates, but the roller does not turn. It has a new belt and the roller brush is clean. Any suggestion on what I might do to increase the suction and get the roller bar moving?

make sure it has a clean bag and not clogged up

Hi there. It sounds like you belt may be stretched. Simple turn vac upside down, start it up and carefully press your hand on the brush. If the belt is stretched the rollewr will stop turning. If this does not help, you probably have a clog in the power head area. Hope this helps, Chris

If your brush roll is turning and your bag is not overly full, then the only other thing it can be is a clog where the bag connects to the vacuum. Turn the plastic part out away from vacuum and lift off to see if you have something clogging it. It would have to be something big, but not so big that it could not get past the fan. As a rule of thumb, KIRBY never clogs. I suspect that your belt is stretched out and your brush roll is not turning while on the carpet so the brush roll is just in the way rather than brushing your carpet to pick up dirt.

I have a kirby Diamond series and the 'green light' on the upper right side (while standing behind the vaccum) does not come on and when it doesn't come on I noticed that it does not sound as though it is picking up at all. I have changed the belt, placed a new bag in it and made sure that there is no clogs. What else could it be?

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 button is for high speed/low speed or suction.

I would check the brush roller and make sure it turns good and replace the belt on it . When you smell burning rubber most of the time it is the belt .

Take a look at the help article here. If bristles are worn you may need to install the brush roll in a different position (details HERE) or purchase a new brush roll.

Good Luck

Is the bag emptor all of the way on? It will blow out if it isn't, But being new, you must have a number to call, it is under warranty so they should be able to help you out.

If this is a Hoover vacuum, which model is it?
