My Dyson works perfectly well with the base plate. As soon as i use the hose part it tends to loose all power and i cant even stretch the hose properlu


The hose is blocked, so you have very little suction at the end. The vacuum in the hose is pulling the hose shorter. With the vacuum turned off, push a broom handle through the hose to dislodge the blockage.

When the dyson is in the upright position it goes off and I cannot use the wand . . . I have cleaned the filter and nothing is stuck in the hose but the wand has no suction power. HELP! I love my DYSON! ...


Here is something to try. Follow the hose down to where it snaps into the main base. My hose has come loose a couple times. There should be to clips that you can pinch to remove the hose. Make sure it is fully snapped in.

When you remove the hose, is there suction coming through that rectangular hole?

Hoover turbo power 3100 is loosing suction


The suction that is lost is usually from a plugged up inlet to the filter bag. Check all areas the debries go through for you will find a spot clogged up especially at the bends were it catches all the time causing this problem

It could be your belt, if it is loose it will not turn the roter at its max power which means less suction.

EF 1750 has lost suction power. There is a noticable decrease in suction power even at the power unit inlet.


Disconnect the actual pipe where it meets the vac. Then test the intake for suction. If you have poor suction still, check the intake itself from inside the vac body for blockage, then check the gasket on the pail for mis-alignement.

If you have suction at the actual intake, your issue will be in the house piping. Look for any damaged inlet doors which are ajar, also look at any inlets you may have recently removed for painting or renovation work. Each inlet has an o ring seal which must be properly aligned. If not aligned you will hear a hiss at the inlet when the door is closed.

Last check where any exposed pipe or pipe joint could have been jarred loose or damaged, basement , garage, etc. Post back to advise what you find

The machine will not suction - it will spray and spin the brushes but will not suction - the power is going to the machine, but it will not suction.


Disconnect the suction hose. While running, check the suction port if it works, by putting a piece of paper. If the paper is taken in, then it is oK. Now, check the suction Hose for breaks or opening before the suction head. Breaks or opening breaks the suction power at the suction head. Loose connection between the suction pipe and the suction port also must be check as this will also cause the same
problem. You may need to replace the suction hose

Turns on, brush rotates, but no suction.


the only thing i know about vacs is if there is no suction its blocked might have sucked up a piece of plastic bag and wraped around the fan hence no air or the screw that holds the fan has come loose take your filters out and turn on you may have sucked up fluid and not known it hence filters are blocked also brushes may seem alright but may be worn under half there fore springs are not at right tentsion if your armiture is black where the brushes run on may not be getting a good contact or if it smells burnt good chance you burnt it out then theres the power switch test with multi tester the check for loose terminals then test the field coils are correct ohms as well

Loosing suction


Well you did not state what model and brand this is, but usually if the hose or the dirt inlet by the brush roll gets clogged, then you lose suction. If you can't figure it out, usually there is a year warranty, take it in for warranty service.
