Dyson DC07 Bagless Upright Cyclonic Vacuum

How to Identify and Fix Common Vacuum Problems ?

Your Dyson DC07 has been rejuvenated with a new drive belt, allowing the brushroll to move freely while it cleaners your home.
Most cases of a jammed or stuck brush bar are quick and easy to fix, simply pulling the debris gently from the brush bar. Alternatively, if you need to clear a problematic blockage, you can take the brush bar out of the housing easily, for quick maintenance.

Brush Head Bearings Are Clogged or Have Failed

These are symptoms of bad or dirty bearings. You should remove the brush roll or rolls from the vacuum. Check to see that the bearings at the end of the brush roll allow it to spin freely. Make sure that there is no hair trapped in the bearings.

If your brush is scratching your floor, or not cleaning as well as it used to, then you may want to replace your brush bar.
Inspecting the Vacuum Commutator for Motor Brush Problems

Test that by turning the motor off and pushing on the center shaft, the armature. If it has any play, besides spinning, then replace the motor. If solid then replace the brushes – motor brush replacement instructions.

If the brushbar spins fine by hand and fails to spin, the belt may have slipped or snapped. It`s pretty easy to change the clutch or replace the clutch belt. 1) Remove the soleplate by turning the light grey plastic screws with a flatblade screwdriver or a coin at a quarter of a turn anti clockwise.
If your vacuum`s brush bar is not turning, the bar may be clogged from hair and other debris. Ensure that the brushbar button, which is gray and located next to the power button, is turned on. If this is not the issue, then the brushbar itself may be damaged or stuck.
Your Vacuum Has Suddenly Gotten Extra Noisy

Just like noises under your car hood, belts that are stretched to the breaking point, or that have become loose can indicate that problems are on the way.

The DC07 had a long production run from 2001 until 2008, and came in many different colour combinations.
The Dyson DC07 was introduced in 2001 with brand new Root Cyclone technology.

We have a Hoover upright vacuum cleaner, model Core 7. There is a switch that turns on and off the brush drive. This operates via a cam with a bearing putting pressure on the final drive belt to engage the brush head.

My brush head is not turning and with the lever set to engage the drive there is still considerable slack in the final drive belt.

There appears to be only a bearing deflecting the belt, should there be a pully or other device mounted on this bearing? There is so much slack a

ANSWER : Yes, there should have been a white plastic sprocket on top of the bearing – in its channel the belt would sit. Unfortunately no parts are available for this unit that can be bought retail – only available by order to dealer repair shops....
Unfortunately to fix it you must send it to one and that would be more expensive than a new one. Just junk this chinese POS and buy another chinese POS.

Hoover WindTunnel Self-Propelled V Belt
ANSWER : I had this same problem with the V belt on my Hoover Vaccuum..
.There are three (3) basic things that will cause the brush roll not to spin..
.1. When handle is upright, brush roll is OFF..2. When switch is set for HARD surface, brush roll is OFF..3. Broken/worn FLAT belt or V Belt, brush roll will not spin.
.
.I noticed that the brush roll was not spinning when my vacuum was set for CARPET. After removing the cover I noticed that the V belt was loose, I thought the belt was worn so I purchased a correct replacement belt and installed it, but the new belt was also loose and when I turned the large flat belt pulley it did not turn the V belt pulley at the same time..
.I double checked the surface setting and I had the vacuum switch set for carpet, but still when I released the handle out of the upright position the brush roll would still not spin..
.My aggravation finally led me to this posting on FixYa’s website..
.The first thing I did was checked the screw to the left of the V belt as suggested by ejmjr5 and this did nothing to solve the problem or create more tension on the V belt, even when the upright handle was not in the upright position..
.After playing around with the surface setting control switch/nob I notice that when I moved the switch out of the HARD surface setting and over to CARPET, I had thought that the switch was set for CARPET as it visually appeared, but I was not pushing the switch over hard enough to click it into the CARPET setting mode..
.VOILA, the brush roll now spins correctly even though the V belt seams to be too loose for the pulley..
.You really have to force the switch into the CARPET setting. Be sure that you hear the switch/nob click into place..
.Now you can effectively clean up after that hangover of a party!.
.Burp!

The original belt on my upright Kenmore Progressive broke and I replaced it with the spare that was in the vacuum. The vacuum and spare belt are about 10 years old. Then the spare broke after one vacuuming session and there was a burning smell coming from the vacuum. I ordered new belts and replaced it with the new belt. It seems to be working fine with no smell. I checked the belt after I vacuumed the family room and although it was in tact, the belt was very hot. Is that normal? Should t
ANSWER : The belt heats up due to the friction, as well as being in contact with the shaft of a hot motor. It is normal.

Hoover Wind Tunnel 7500 Brush not Turning. I have replaced the Brush and the belt. The problem does not seem to be either to me. I believe might be a missing part. The place were the belt hooks on is a metal pole which never seems to grip the belt well. In fact it seems loose most of the time and slips on the brush, causing the belt to eventually burn up. Could there be a missing plastic or rubber piece meant to hold the belt taught  on the metal pole?
ANSWER : Check the Idler Pulley part Number 43241004 (Item 13 in the IPB)

My model F5906-900 — problem is the brushes have stoped working… I pulled the brush assembly out by holding the two tabs, and all seems clean and the brush assembly rotates easly… onced the brush assembly is removed. What I did notice is the female driver slot (found in the main assembly unit) that drives the brushes seems stuck..Is that normal when the machine is not hooked up to power? How can I get the brushed going??? it is a good machine, but the brush options is important too it’s ab
ANSWER : (1) Assure the Brush Control on the hood is NOT set to the OFF position.
.(2) Remove the brush assembly by pulling/unlatching it from base on each side.
.(3) Does one of the brushes have the drive pin present? It should be about ¼ inch square, and two inches long. It attaches the brushes to the drive mechanism.
.(4) Remove and clean the intake filter. One the base of the cleaner, behind the brushes, squeeze the two red abs together and pull the panel down to access the screen. Clean the hair/debris off the screen and reassemble.

I’m using (or WAS using) a Eureka ”the boss” model 8803. The belt broke, no biggie, so I replaced it with a Eureka model U belt, the problem is when I put the new belt on and turn on the vaccuum, the belt breaks again. I am also having trouble getting the brush roller to fit right when the belt is in place. I can’t find any sharp edges that would cut the belt,nor can I find where any small bits may have broken. Anyone have a solution for me?
ANSWER : First, make sure you have the right belt, second, i am thinking that you are not lineing the roller up right, it will only fit one way. look at the ends of the roller and the grooves where it slides in, you should be able to see clearly how it goes.

Eureka 5843 belt keeps slipping off of drive spindle.
ANSWER : Tough one. Typically the only 2 things that the belt contacts is the motor drive spindle and the brush roller. Anything else would only be there to protect the belt from debris. Can you turn the brush by hand and see why the belt is coming off? Is the spindle wobbly? If so, you may need another motor as I don’t think it is easy to get parts for the motor. Hope this helps and good luck!

Bissell Proheat 2x Series 8920 – Brush Belt Metal Shaft Sprocket won’t turn
ANSWER : Most likely the brush motor is bad and not turning, part #2036757, would sell for around $23. To get to it, start taking out screws on the top cover, that motor is under the that top access cover.
