Manual says to tilt the vacuum back so the front wheels are off the ground (unit turned off of course) and make the adjustment. May take some back-and-forth force, but should adjust. If not, then something is jamming the switch.

    I have one the height adjustment cam works fine, but the wheels are jammed to a height that is higer than the highest setting on the cam. I tried to force the wheels down against the cam with no success.

SOURCE: vac is supposed to have auto height adjustment but it doesn't

If the brush isn't working then its maybe because the drive belt is broken. Locate cross head screws on top of the hood of the Eureka vac (two at the front usually and one below the duster or at the left hand side if looking at the vacuum from the front) Once the screws are undone check to see the drive belt is intact. If its not then replace with a new one and check at the same time that the roller brush is properly put in. If the drive belt is ok then check the brush roll - something may have jammed it if it isnt the belt. Dont forget to rate please.

Dirt devil breeze bagless height adjustment mafunction


Hi there! If your vacuum is suddenly hard to push your roller lifter assembly, which controls the automatic height adjustment, may be damaged or broken. Check your roller lifter assembly located underneath your unit for damages. Also, your brushes help to maneuver through carpet, check that your brushes are still spinning. If not, replace the belt on your vacuum. I have included a link where you may visit to purchase a replacement belt for your vacuum. Hope this helps!

It's hard to push because it's literally sucking itself to the floor. Adjust the height control to raise the level and allow more air to get in around the edges, should relieve the vacuum pulling it down. Possibly somthing is wrong with the height adjustment control, allowing machine to sit too low to ground. Hope this helps.

Height adjustment not working.


It's likely the circuit board that controls the height adjustment motor, or the motor itself. Your local sebo service center will be better able to test to see just what is wrong. Though it wouldn't hurt to take a look at the boards sometimes they're visibly burnt, or connections can be loose. Good Luck!

This is a typical problem you are describing. I would recommend you change the belts, this will resolve the "hard to push" and most likely resove your issues. based on the s/n given you maching was made on sept 2004.

When i am vaccuming it is really hard to push how do u change that setting


Raise your height adjust, and replace your belt. This will fix 99% of the problems with vacuums being hard to push.

Your height should only be as low as it takes to get your brushes to just make contact with your carpet. Peoples' natural inclination is to slam the vacuum as low as possible to deep clean the carpet, but in reality it's restricting your airflow and is cleaning less effectively, as well as making it harder to push.

A properly designed vacuum should be easy to push any time there's a new belt on. If these two solutions don't make it any easier, make sure your wheels are spinning free on the bottom.
