Dirt devil ultra not sucking up debrie. nothing is filling up the canister

It sounds like there is a clog in the hose itself if you have no suction from the end. If it is bagless remove the canister from the machine or if it is a bagged machine remove the bag. If you have a shop vac attach the hose from the shop vac to the end of the hose of the dirt devil and try to suck the obstruction out that way. Sometimes it is possible to remove the clog this way. You can tell if you have suction from the debris port to the bag or the canister. If not you may need to use a snake or coat hanger to pull the clog through.

The belt is probably broken or off the pulley. These will build up hair and rug fiber around d the moving parts and force the belt off. I don't know the exact access on this model but a cover will need to be removed. Some models require Phillips screw removal of complete upper or lower cover. Be sure to clean out all debris and re install or replace belt with new.

The hose is probably blocked. If possible reverse it (put the intake of the hose on the canister connection) that should suck out the obstruction. If that fails try to carefully push a broom handle into the hose, preferably from the end that connects to the canister. Put the hose back on normally and see what happens.

Did you try to use a different plug in?
Any shorted wires or burnt?

Your belt is probably worn or broken. You need to replace the belt if you haven't recently. You can get the belts you need here:

my dirt devil is blowing out air instead of sucking up.Tried new bag.any other solution to fix

TOSS IT and forget it! I have never used a hand vac that worked that was worth the effort of turning it on .... I suggest they are all junk ... I found very few vacuum cleaners ... actually **** especially anything made by dirt devil ... I do have a bagless Bissell 6579-2 that I purchased 4 years ago at walmart for $49 ... It outperforms any vacuum I've ever used, including my worthless Shop-Vac that I paid a lot more for ... this Bissell vac SUCKS ... It could **** the barnacles from a steamship!

Have you check the filter/baskets to make sure that you don't have a large piece of debris that is preventing suctions? You will also want to check each section on the vaccum systematically to make sure that there are not cracks or noticable areas of damage that would prevent the pool cleaner from working. Is is not moving at all or just not sucking properly? Can you give me more details as to what it, exactly, it is doing?

well the first thing i would look for is if the brushes turn turn it over bump the on off switch if it turns the belt is fine but u might have a clog in the bottom if that the case have to pull cover from thhe bottom take the belt and roller brush off and look up insde where the junk sucks up use a wire hanger if u need and after that clean out where the dirt goes in bag or canister........hope this helps
