Question about Dyson DC07 Bagless Upright Cyclonic Vacuum

1 Answer

Lack of suction in hose

Vacuum runs fine, then approx. 15 sec after the hose is taken out, a inhale and pop is heard, then there isn't any suction. Like a ball got caught in the intake valve. It's a Dyson DC15, 4 years old.

That popping sound is the bleed valve activating - it indicates that there is a blockage in the machine somewhere, probably in the wand if you're saying that there is no suction in the wand.

- Take the wand off the back of the machine - press the two gray buttons to separate it from the hose - hold the wand in the air and look through it - if you can't see the light coming through the other side there's a blockage in the wand - taka a long object like a meytal hanger and remove the blockage.

If that's not the problem, call the Dyson helpline for further troubleshooting, they know what they're doing.

    Thanks for the info on the gray buttons -- the clog was in the bendy part and I couldn't tell just by looking down the wand. Suction (and clean carpeting on stairs) is restored! Yay!

Lack of suction


You don't say what type of vacuum but it still sounds like a blockage or a split in a pipe... have another thorough look..

Is exhaust air blowing out of the machine... Is the motor running at a higher pitch than normal...?

Hi troupdavid,

I see that your Vacuum is having issues with it suction, you mentioned that you took it a part to clean it, see steps below.

  • Check if everything is inserted properly and is in place.
  • make sure the the Vacuum airflow does not have anywhere else to come out from, cause if there is, the vacuum suction will really not be really getting enough suction to be able to get dirt Off the floor.
  • Make sure the bag is correctly placed in the Vacuum and is tucked in properly for proper suction.
  • The hose should be twisted to be locked into Place, either clock wise or counter clockwise which ever makes it lock to the hose socket.
  • Also check the agitator shield beneath making sure that the Belt is not pinched in or squished by the Agitator and the Agitator shield, this can also cause lack of suction for the Vacuum.
I hope that this will be of help regarding your query.

Have a nice day,

mvincentc

If the motor is running, there should be suction. Possible problems depend on whether it's a canister or upright and are:
A clog in the hose, UR or canister. Detach hose. Drop small coin in one end and lift hose causing it to roll out the other. If it does, no clog in hose. Drop same coin into hose opening on power head. If it rolls out, no clog in PN.
Broken fan blades, UR. Needs to be taken to shop for repair/replacement.

A reset button is for use if the motor isn't running, so won't have anything to do with the suction.

Vacuum not picking up


At the top of your wand, do you have a plastic swivel that cover a hole in the wand? This is for when you are cleaning curtains, and if that is open, or cracked you will loose suction there... also check your hose for cracks, or breaks. If it were in the shop I would put a gauge on it... normal suction is about 80-95 inches of water lift at the end of the hose. Once you have check each section of the hose, and wand, check the housing for cracks, a missing gasket (Very Good Reason For Lack Of Suction) As to your Filter, how long have you used that one filter, you can clean them for a while, but once a paper filter gets full of FINE dust you won't get it all out, you will have to replace the filter itself at that point. I hope this was helpful.

Vaccum has no suction


Here is what we did to fix the problem of our vacuum having no suction.
We unscrewed the three screws on the back and took the hose off of the vacuum.  Then we took the hose outside and put the water hose through the vacuum hose and turned on the water.  After about 30 second the water pushed through a dust bunny the size of a fist and a marker.  Basically, the vacuum did not have suction because the hose was clogged with dust, etc.  After reassembling the vacuum, it worked just fine.

Dirt devil mvp not sucking


Could be bad filters, is there suction at the end of the hose. That will tell you which direction to start looking. If no suction at hose end, then filters could be the problem. If you have suction, then the problem is down lower, dirt inlet is clogged, if belt has never been changed, then I am sure it has stretch to the point that under load it doesn't turn like it should. Could even be that although the motor is running, it may be running at a slower speed, in which case it would have to be replaced.

No suction in vacuum on a Panasonic MC-V7355


the device is a bypass which allows some air flow when there is a blockage. you have a blockage somewhere i suspect hence no suction. check all hoses carefully. take off the base and check the air duct away from the brush roll

Willnt pick up good...


I had this problem once too. When the hose is inserted into the vacuum, the floor unit (where the spinning brushes are) becomes the head of the vacuum. In other words, the suction goes through the floor part and then up through the hose and into the vacuum. If the suction is good when the hose is out, the the problem is blockage at the bottom piece. Take the cover off of the rollers (it is one screw then it pops right off) and see if there is a bunch of lint/hair/gunk blocking the suction hole. You could also take the hose part out of the vacuum and look down the empty shaft with a flashlight and see if you see anything there. Hope this helps!
