No suction from my kirby sentria

1. Put the hose and see if suction is good. If it is - you may have had nozzle installed wrong or brush roll may be worn out (bristles must be sticking out of the nozzle by about 1/8 of an inch).
2. If there is no suction with the hose either - check if bag is not overfilled to the point where dirt is blocking the fill tube hole.
3. If two above are fine - something must be blocking the air passage from the fan to the bag. Check for clogs in the fill tube (tube inside the cloth bag) and mini emptor (bag bottom plastic part) and also see if there is something blocking the exhaust on the vacuum. You may not even see it so use a piece of wire. Once I found a sock there and it was so close to the fan that I could not see it in the hole and was only able to get it out using a homemade hook made from a coat hanger.

You are referring to the green led light on the front of the machine that tells you the brush is rotating? this is operated by a small magnet on the brush roll, when rotating it generates a small current to bring the light on. Remove the brush roll and check for damage behind the green led inside the case, also check for the magnet on the brush roll, ensure it is not missing and the brush roll is in the correct way round, magnet needs to be at green led end (ie to the left)
Magnet is fitted flush within the brush roll close one end and is around 6mm 1/4" diameter.
Green light not working will not affect the machine in any way.

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.

You may have suction but if the belt is worn the roller brush won't spin and therefore won't pick up anything. You can get a replacement belt here:

As far as picking up - I suspect that your belt is not properly installed. Watch the video manual HERE. in the first halve of the video there is an instruction how to properly instal nozzle.

You have to turn the bag about 30-40 degrees countercloclwise so plastic protrusions on the tube top adater (ones that keep bag attached to the tube) will allign with cuts in bag cardbort so you can pull the bag off the adapter. If you will take a look at the new bag - you will see what I am talking about.

Have you checked the fan? It is what creates the suction. If ok, then you may have a motor problem, sometimes they run but not up to speed, then suction is lowered when that happens.
