Question about Dyson DC25 All Floors Bagless Upright Vacuum

1 Answer

Squealing noise from the top

I can isolate the high pitched squeal. Its coming from the top round connection where the seal is. I have replaced the seal with no results. If I monkey with the collector bin while the vacuum is on, I can get the squeal to stop, but there is no way to get it to stop while I'm actually vacuuming the floor. It squeals with use of the wand as well. It almost requires ear plugs its so irritating!

Take the HEPA filter out of the ball. Run the machine without it and see if it quits. My guess is that it will. You can get some scissors and cut the rubber seal off the filter and re-install it and you squeal is gone.

    How can I stop the squealing noise in the motor on my Sanitaire wide track commercial vacuum? It's making a squealing the minute I turn it on

    Is it the motor or the brush roll? Remove the brush roll and belt and see if it still squeals. If not clean or replace the brush roll and get a new belt. Inspect the fan to insure there is not something stuck in it. If it's the motor you can try to clean it, make sure there is not something stuck in the motor causing the noise.

    I have a DC41. The power head wont turn and is making a squealing noise.

    Sounds like your power head is seized or almost seized. Possibly real dirty. take apart and lubricate ends and replace the belt I feel is slipping Hence the squealing.. Clean all parts thoroughly.

    This sounds like a belt issue to me. The belt usually runs from a drive shaft to the rotating beater bar / brush. Both the drive shaft and beater bar / brush that are contact with the belt must be clean. Oils, etc. can interfere with the grip on the belt. If the belt is squealing for very long, the drive shaft can damage the belt. make sure you're using the correct belt - and have all the parts in their right places. Recheck your work and provide the vacuum make and model if you're unable to get it working properly.

    Radiance RAD.4 Vacuum squeals when powering on or running the brush

    It might be a bad bearing in the brush roll or the hall sensor is squealing. I recommend taking it to your local dealer to have it checked. Failure to fix it properly could cost more in the long run.

    Sebo squealing

    Just spend all afternoon working this one out. Take the upright section away from the bottom by pressing the release button at the bottom of the upright section. You will see two pipes. One pipe has a grill on the top. That is the problem. Mine was slightly loose which may have caused the whistling or it may not have been making a good seal with the upright section. Anyway, I took it off altogether and the noise has gone

    Remove all filters and turn on the vacuum cleaner and check the hose for suction.If it has good suction turn it off and remove the belt.Turn it back on and if the noise is still there you have a motor bearing squealing.It's probably time to replace the vacuum cleaner if you have a motor .Most of these box store models are designed for replacement if a major component fails.

    Bearing screeching?

    Yes, it could be a motor bearing. Another possibility is the fan could be broken. Remove the bottom plate from vacuum. Spin the belt motor pulley slowly and view the fan. You may have a plastic fan that has broken or something is keeping the fan from spinning. Here are links with illustrations to an online guide. (the links will say "belts" but it will show how to get to the fan). Click the one that best matches your vacuum.
    Hope this helps.

    My Vacuum keeps cutting off after just a few minutes of use

    You probably have a clog that is overheating your motor and tripping the thermal cutout. Check all air hoses and inlets for clogs. If all of your air pathways are clear, you most likely have a bad motor bearing, also indicated by a high-pitched squealing sound. If that's the case, it would require a motor replacement; which is not usually economically feasible.
