The brushroll has it’s own motor so the brushes spinning doesn’t necessarily mean there’s not a problem with the wiring, the switch, or the motor.
Assuming you haven’t inadvertantly set the selector switch to floor when you wanted to use the hose or vice versa, try the following.
Start with the motor/impeller first. Take the dust canister off and turn the vacuum on. It doesn’t matter if you turn on the brushroll or not as you’re looking for suction.
With the vacuum on feel for exhaust out the front of the motor (by the secondary handle on the bottom. Also put your hand over the area where the dust canister sits. You should feel strong exhaust and suction respectively.
If not, then you should take it in to a technician as going any further requires disassembly.
If you feel there’s enough suction, then it may be as simple as a clog. This vacuum has a particularly easy air path to check. There’s a clear snap-on door on the bottom to check the brushroll and neck. Then from there it’s a straight shot through the canister itself before dumping inside and going through the filter. If it’s the hose, you can turn the end clockwise to remove it from the body of the vacuum and use a broomstick to clear any clogs.
If it’s not a clog or filter then you may try cleaning the seals (one round at the bottom of the canister where the canister mates to the body and a rectangular one in back of that where the dust runs up and into the canister.
Good Luck!

.With the vacuum flattened (straightened) out, turn it over and remove the back roller cover, (2 screws) once off, the roller should just pop out on the opposite side (opposite from the belt). Don’t forget to turn the roller to center the belt once you have it on.
.I had the same noise problem as everyone else here and found no solutions on the web. i took the thing apart a few different times to no avail. i read here that it could possibly be the brush bearings but i didn’t believe that was the problem. i removed the brush and spun the bearings in my hand and they seemed to be ok, i didnt feel or hear anything wrong. i looked around the house for something to use to lubricate the bearings but i found nothing. i then remembered the all purpose wonder tool that is olive oil. i carefully added some to brush bearings on both sides and spun them in my hand a little bit and put everything back together. Voala! The vacuum now runs as quiet as the day i first bought it. i no longer feel ashamed to vacuum at 11pm and my neighbors can get some sleep 😀
