My Sentria obviously has suction - if I tilt the head up, the carpet comes with it. However, it doesn't pick up even small tufts of dog hair, small bits of yarn, bits of vegetation. The carpet underneath looks cleaner - but there's still stuff on it. Surely I shouldn't have to pick that up by hand?
I am using it on a low-pile area rug with head in position 1 or 2.
Also, how do you remove the bag? I know to rotate the bag at the top, but gentle or otherwise, the cardboard bends but the bag doesn't budge,
To double check if the brush is rotating, there is a green led light on the top right of the power head. If the light illuminates the brush is rotating, which also means the blower is working. As long as the bag is clean, there are no obstructions in air flow and the brush is rotating the vacuum should be working fine. If the brush is not rotating the belt is either broken or not engaged. It sounds like the brush is not rotating, which is a very easy fix.

Re: Kirby Sentria doesn't pick up visible dirt
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.

This is unused shampoo attachment. We buy new parts and assemble this shampoo attachment so you will be the first one to use it.
Tray with shield
Container with cap
12 oz. shampoo
NOTE - pictured Kirby Sentria shampooer box may not be included.
If you have never used this shampoo, we highly recommend reading our ONLINE MANUAL. This is a simple but very effective unit but you have to learn how to use it and "common sense" will not be enough!
HOW TO - V I D E O S
Tank with soapy solution is attached in place of the bag. It utilizes the air coming out of the exhaust to blow soapy water on a small screen that turns it into thick foam. The foam is simply laid over the carpet (you must vacuum before you shampoo). Foam allows the spread of a small amount of water over the area so carpet is not soaked all the way through. Foam is left on the carpet for a few minutes so it has just enough time to moisten the fibers of the carpet and loosen the dirt (not too long otherwise foam may dry). Then foam maker is set to "OFF" and you slowly pull Kirby vacuum over the area where you laid the foam. The rotating brush in the shampooer nozzle rubs the moisture off carpet fibers and and throws it into the tray in front of the unit. You will not see gallons of dirty water but that is because you did not put it on the rug in the first place. Carpet should dry within 1-4 hours (depends how many times you laid the foam and what is humidity in the room). After it dries it has to be vacuumed. Solution that did not get picked up with the shampooer brush dries and shampoo additives do not let the dirt stick back to the fibers of the carpet. It is loose when it dries so in order to pick up what is left, you must vacuum again.
You can use any carpet shampoo sold in your local store but make sure that this is carpet shampoo that makes foam and pay attention how much you have to dilute it with water as various shampoo products come in different concentration. Avoid using "just anything" that makes foam. Some household chemicals (such as dishwasher fluid) will do great job but it will leave carpet unprotected so dirt will stick to it so well that you will have a filthy rug in no time.

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).
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.
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.
I just took a stiff piece of coax cable, and took the bag off where it attaches to the main unit, and took the head off ( the part with the brush roll in it) AMD cleaned every thing really well, turning the spindle for the fan while " snaking" it and pulled out a baby sock! Ta-Da! Works like New.

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.
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 machine does not actually suck the suds up.
Basically the machine lays the foam down which then crystalises and absorbs the dirt in the process.
Once this has had around - 4-5 hours to dry then you vacuum up as normal taking the crystalised dirt away.
You should really use the Genuine Kirby product as it's very good but you can also you any other DRY FOAM shampoo.
Hope this helps
when you install the hose connector it trips a switch that switches the vac motor into high speed because the vac path is longer using the hose. check the belt after you remove the front. make sure the direction of rotation is in the direction of belt travel stamped in the impeller. try adjusting the head height
