No suction but brush turns - Vacuums

remove the brush from the enclosure. use a quarter rotate the cover, pull out the brush and clean any debris. operate the unit before installing the brush to see if the device in fact operates as designed. if not replace the unit, if so install the brush and bust out laughing!

How bout the hose? Is it blocked?

Remove the machine side of the hose--is there suction at the machine? If so, run a broom handle or similar through the hose to dislodge the clog. If no suction at the machine, you may need to fish out debris with a hooked stiff wire from the port. Remove the bag and examine the port area underneath for similar clogging. Finally, check the brush area underneath the machine bottom plate for more obstruction. Also, check the brush assembly for debris accumulation. Remove the drive belt and check for free turning of the brush. If turns hard, remove the brush, clean the bearings and roller pins, then apply a small quantity of light oil like 3-1 or sewing machine oil. Hope this helps!

You need to replace the belt that turns the brush.

Check for a blockage between brush and entry into dust chamber, if something has not made it's way to the dust chamber could result in low suction1

Check your belt. It is broken or stretched out. Replace the belt first. Should be your answer

Is the suction tubing in the head assembly clogged, is the belt broke? If the if the belt looks good the brush may be turned off and you may need to turn the brush switch on.

If the cogs on the belt and brush roll are ok, then probably the cogs on the pulley are worn off, or the pump isn't turning, is the flat belt ok? If all of this is ok, then replace the pump, part # 2107181If no suction, is the black oblong gasket on the top of the clear window. It seals the gap between the tank and the window, no suction if it is gone. Also should be a red plastic screen on the edge of the tank lid, it may be clogged.

you probablly need a new belt clutch it should go to a vac shop it isnt an easy fix

You won't feel a great deal of suction like you tried to do it. But look at the fan, if it isn't worn down, and the bag fills with air when you turn it on, then the suction should be ok. If you haven't changed your belt in awhile, I am sure that it is stretched and is having trouble turning the brush roll.
