    I don';t get it....The power nozzel will stops spinning on ANY carpet that I try it on! Sometimes the belt jumps ff the motor shaft but mostly the belt the motor shaft....What is wrong with this design? We exchanged our first one because we thought it was defective. The second one does the same thing. This has to be a design flaw and I am extremely disappointed in this vacuum. We have had this vacuum for only 2 months.

    Give me a break! I have the same stupid problem as "rjstanly" and "ocdmond875". However, I have a different model S3765. I too bought a Windtunnel just before Christmas and ended up calling for help which was actually talking to a call center. That certainly didn't help. So, I took the vacuum back. I then went to Sear and found an anniversary version which is the one I have now: S3765. Once again the bristles on the power nozzle catch and drag and the blet comes off. I've called again and I've even sent a message to Hoover Canada concerning the issue.

    I have to say that I love this vacuum cleaner with all the great attachements. The extra attachments that comes with the Anniversary Model. One partcular attachement is for vacuuming stairs and I've never experienced such ease of use. It's wonderful!

    Now if they could only fix the bristle problem. I too have reshaped the bristles in order to fix the problem. However, why should I have to trim brisltes on a power nozzle of a new vacuum cleaner. What is the world coming to??? Give me a break! This situation needs to be fixed and fixed soon!!

I've had my Hoover S3755 for about 2 years and loved it, at least until the last couple of months when the "belt slipping off" problem started. I changed the belt and the vacuum would work for a little while then the belt would come off again. I put on a new belt again and within minutes the belt had slipped off. I took it to my local vacuum repair about 4:00 in the afternoon. By 4:45 I got a call from the repairman that he'd fixed my vacuum! What did he do? He put a different belt on it. He put a Rainbow belt on my Hoover that's thicker and doesn't have as much "give" as the Hoover belt. It's also a little bit wider than the Hoover belt. Now when the brush slows or stops at a carpet edge the belt doesn't slide off.

You should not use this powerhead on any natural or oriental fibre carpet. If you check the brush roller, you will see that the bristle extends out the bottom of the powerhead quite far and that the bristle is very stiff. This is o.k. for synthetic carpets, but will be too aggressive on natural carpet. It will pull material out of the carpet and eventually thin it out. You should use a passive air turbo or a carpet tool for this rug.
As far as the belt is concerned, if it is over a year old, it is due to be replaced. Old belts are stretched and will come off because they are worn out. You might also check to make sure the motor is in place correctly. It is very common that when people want to check the inside of the powerhead, they commonly remove the three screws that secure the motor, thinking that these screws will open the powerhead. If you observe the area between the screws, you will notice that there is a "no screwdriver" warning there. The four screws for the hood are recessed and not as obvious as the motor screws, so this mistake happens quite a bit.

I found it easier to trim down the bristles with a high quality pair of scissors and reshape them. By cutting at an angle, it reduces the amount of drag created by the "pull back". The brisltes don't go as deep into the carpet but still maintain contact enough to grab the dirt without pulling out the fabrics. It took a little time, about 1/2 hour and seems to be fine. My Vac was only one month old when this started. Also, while you have the guards off, double check the bristle bar for ease of spin and lubricate with silicone spray if needed.

Powerhead won't rotate on low-pile carpet


Sounds like the vacuum is adjusted too low on the carpet. Adjust it to a higher level. If this is not the problem, then the belt is slipping. Buy a new belt.

The beater brush will no longer drive under a load on short pile carpet


Have you tried changing the height adjustment? There should be a knob or lever that allows you to adjust the height of the beater brush to accommodate different carpet lengths. Even with a new belt, the brush will not spin if the height is too low. Try adjusting it all the way up, then while it is running, adjust it down until there is some resistance. The beater brush should just barely scrape the top of your carpet.

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.

Kenmore canister power head not working?


Without more info, I would investigate the drive belt, make sure the beater bar is free to spin (no hair or carpet fibers twisted onto the moving parts), and then check that the power is getting to the motor of the power head. Most often it is hair/fibers that collect around the ends of the beater bar. This causes the belt to stall, heat up and stretch due to the drive motor shaft spinning on one spot because the belt can't move. After removing twisted hair/fibers, you probably only need to replace the belt.

Call Hoover and complain, they'll likely send you a new one. The service centers will not be able to give you a belt under warranty as it is a "wear" part.

The suction is quite poor, also definite burning smell after normal use. we only have about 3 years would it be the engine


I would check the drive belts for the beater brush and make sure the beater brush itself is free to move in the holders. Clean the beater brush of all debris and add a bit of WD40 on the two ends between the brush and the holders.
I do not charge for my advice. : )

Belt Keeps Coming Off


Replace the belt with afresh, proper sized one. Yours is stretched. It will be shiny on the underside. hoover belts are meant to fit snug. Check the bearings on the end of the brush roll to remove dirt and thread. The proper belt will need to be stretched into place using the brush for leverage. Likely that your low carpet is more dense causing enough drag to throw the stretched belt.

How do I change the belt in a Hoover U4262-930


You got the second hardest part done; the hardest part is what you're asking about.
To get the new belt onto the drive shaft I used a long screwdriver for leverage and wrapped the end close to the shaft and with some elbow grease, got it to "slip" on to the shaft. It took a couple of tries, but once I overcame the fear of the belt breaking (because it has to stretch big time), I managed to get it one. Of course, the other end of the belt has to be wrapped around the roller first.
I found a link for a tech manual for this model, but it didn't help much....
good luck.

Hoover s3755 bagless windtunnel canister


Very likely it's the cord at the nozzle neck. These cords flex when you vacuum and they often break internally where the cord goes into the neck. Turn the vacuum on and wiggle the cord at the powerhead and see if the powerhead comes on and off. If this happens, then you will have to replace the cord.
On some of the early models, the receptacle in the hose, where it plugs into the top of the wands, will break away from the plastic pins it sits in, and the receptacle will slide back into the handle, which means that it will not plug into the powerhead connection when you connect the hose. You can check this by looking at the end of the hose and observing if the receptacle is sitting flush with the opening it sits in. If it is pushed back, it will not make a complete connection with the powerhead cord that is sitting at the top of the wands.

Problem with use on carpet


Very professional and useful account there of the problem and investigation so far! Unless you've got evidence that your machine is damaging the carpet, I'd be inclined to put a new belt on and see if that fixes it. Carpet makes the beater/brush roller much harder to turn than bare floor does, and this can be enough to start a loose belt slipping (after which things don't naturally improve themselves). A.
