Suction cuts out how to fix. Vacuum pulls water for about 20 to thirty seconds and then the suction cuts out.

it could be the filter or on this unit, one of the other 2 filters. The most common overlooked filter on this unit is the filter in the pull out tray under the bagless container. I would suspect that is the culprit cutting off your suction. Pull it out and wash the filter, wash the other 2 filters in your unit as well. Warm water and soap, little bit of bleach to kill the smell and LET THE FILTERS DRY BEFORE PUTTING THEM BACK INTO THE UNIT. I cannot stress that part enough.

Good luck!!

This might help, it was posted on a previous problem but is the same issue you are having it seems: "Here is a possible solution. If the vacuum sounds normal when the green light comes on, then the issue is a suction bypass. Kenmore built a suction bypass in to help cool down and protect the motor should someone either never clean the filter, empty the canister or somehow manage to clog the hose. There is a spring holding the bypass closed and is overridden by vacuum suction. I guess the spring becomes weak, allowing high suction to pull it open which in turn reduces suction so it closes again. It can do this several times per second making a loud racket and slightly affecting performance until the sensor goes green, then the vacuum suction is too low to overcome the spring tension thus why it sounds fine then. The trick? The very hard way (what I did) was to open the vacuum, open the casing where the spring is and pull it apart slightly to increase the spring tension. The easy way is to put tape over the hole where the bypass is. The inlet is under the hose track on the back on the right side as you're looking at it. The hole is about the size of a quarter and you'll see fins across the hole. The tape would keep the suction. The motor would still pull back the bypass but since tape is applied, there would be nothing to reduce the suction thus keeping performance and reducing the noise. However, this circumvents the intended design so you do so only at your own risk."

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.

Here is a possible solution. If the vacuum sounds normal when the green light comes on, then the issue is a suction bypass.

#1 i assume u checked the bag and filter if so equipped?
#2 verify the hose is not plugged
#3 verify hard plumbing not plugged by taking something metal (quarter) and crossing the 2 little metal nubs at inlet (don't worry it is low voltage u wll not get shocked) it should ****
#4 if hard line plugged you may need a second vacuum to reverse flow
are all outlets not creating suction f so detach vacuum from piping and verify that vacuum is not the problem

There is most likely a clog in the hose. If the hose has poor suction the foot probably has poor suction as well seeing that the hose is what gives the foot assy suction.
