Vacuum stops when I try to use hose. The hose is contracting almost flat with very little suction. What do I do?

Your filter may be stopped up and not allowing vacuum.
Your discharge may be blocked. In order to have vacuum you have to have a way to discharge the air.
Possibly your motor is weak

I found this info
Why is my vacuum losing suction?
A motor generates power which powers a vacuum which, in turn, creates suction to lift debris. The most common areas of suction loss are within the hose itself, the vacuum bag, clogged rollers, broken vacuum belt or a faulty gasket. All of these problems will lead directly to the vacuum cleaner losing suction.

Some vacuums have a valve or collar near the handle that you can twist to adjust the amount of suction on the vacuum. If you open it a little it will stop sucking up your throw rugs. IF the problem is not enough vacuum then the HEPA filter may be clogged. It's usually a rectangular filter in a plastic frame. That has to be changed occasionally or the suction of the vacuum will continue to drop off.

Have you tried cleaning the hose from the vacuum end, the end that feeds the sweepings into the cannister/bag? Might be something close to that end of the hose. Also, one reason for a hose not to work is the possibility of a cut or broken hose or a loose connection. The closer an opening like this might be to the vacuum end of the hose, the less suction the unit will have through the hose as it will pull air through the hole/break easier than through the full length of the hose.

Hello :

1: A vacuum pulls air through the bag, then through the tube attachment and then through the base (with the spinning agitator brush).

2:Check for signs of suction. Remove the tube attachment from its cradle and, after turning on the vacuum, put your hand to the end of the tube. Is there any suction at all? If there is a little bit of suction then you may have a clogged air tube.

3:Check the vacuum bag. It may be very full. If it is then remove the bag and replace it with a new bag. Check the suction power again. Has the suction improved?

4:Check the tube attachment. Completely remove it from the vacuum. You usually have to twist and pull the tube attachment out of place at the point where it connects to the back of the vacuum. Check the suction power again. This time you place your hand on the vacuum right where the tube used to come out of the back of the vacuum. Has the suction improved?

5:If the suction power has improved then you probably have a clogged tube. Dog hair, people hair, leaves and more can get lodged in the tube slowly over time and then suddenly block the tube completely.

6:Clean the tube by first trying to shake the debris out of the tube. If this does not work then go outside and run a hose through the tube. Use a pressure nozzle if you have one. Run the hose through one end of the tube. Then run it through the other end. Repeat until the debris is disloged. Dry the tube and then reattach to the vacuum.

7:Has suction power improved or returned to normal power? If yes then you can stop reading now. If not then read on.

8:Check the air hose in the base of the vacuum. This hose is usually pretty short and you can see if there is any blockage. If you see blockage then try to remove it. You may need to reach into the hose with a tool (like a screw driver or something long).

9:Has suction power improved or returned to normal power? If yes then you can stop reading now. If not then read on.

10:If you made it to this step then you may have a problem with the motor on your vacuum. If this is the case then you will need to take the vacuum in to a repair shop.

Things you will need :
1 Philips screw driver
1 flat head screw driver

Warning :


# Always unplug electrical devices before you work on them.

# Never work on electrical devices around water or when you are wet.

I hope this will help .

What I tried and it worked for me is to losen the hose slightly from where it connects to the long plastic tube on the side to allow the little hole to show. What that does is to lessen the suction power a little since the problem is that the suction is too powerful on the carpet and the roller freezes.

chech the hose for a blockage this would cause the hose to compress as you describe

disconnect the hose where it goes into the clear tube on top of the base.there will be a little flapper door there when yo take it off.open the door and take a coat hanger with the end bent over like a hook and pull the dirt clog out of there.but first take the dirt cup off and remove the filter,if its clogged with dirt you won't have any suction.try using the vacuum without the filter in the dirt cup.if you have suction then then thats your problem ,a cloggeds filter

Check the hose for a blockage. If you remove the hose, if there is suction at the point where the hose hooks to the back of the vac, then the hose is clogged. If no suction there, check filters, make sure they are clean.

Generic problem for all Vacuums
No vacuum suction
No vacuum suction

I would advise you to ALWAYS to FIRST UNPLUG YOUR VACUUM before beginning any service procedure.
I am not sure what type of vacuum you have but it sounds to me that if you have a vacuum with a hose (called a powerteam, or canister with a powerhead) the vacuum hose could be clogged , the filter could be dirty, or the bag is too full – run a marble or steel ball thru the hose to see if there is any blockage, by doing that you can tell where the clog is, if there is use the wire coat hanger – straighten it out and bend the end of the hanger upwards to create a little hook and by doing that you can remove the clog if the ball does not go thru the hose all the way, please be careful if you have a vinyl hose, you could poke a hole in the hose and then you would need a hose sleeve over that spot to stop it from leaking, if it is an upright the same rules would apply to the hose, bag and filter or dirt cup filter .

If the vacuum will run without the hose attached, does the suction seem ok at the opening where the hose goes into? If so, then you have a clog in the hose or down below where the dirt is first sucked up. If suction is poor at the vacuum, then check the filters, they go bad after awhile.
