Carpet roller brush not going round - Dyson DC25 All Floors Bagless Upright Vacuum

look for a blockage -something may have dislodged the lever mechanism, or be stuck preventing the roller or position leaver from moving.

Sounds like the little motor that drives the brush is going bad. You need to replace the cleaner head.

If you are talking about the ridges on the bearing blocks at each end, here is how they go. If it is a new brush or less than a year old, the side with multiple ridges will face up as you put the brush roller into the machine. If the roller is no longer pulling against the carpet or it is more than a year old, turn both bearing blocks to the side with only one notch showing. That will lower your brush closer to the floor and let it pull against the carpet. If you have it in the lower position and it does not pull, you may need to consider replacing the brush. Hope this helps.

Hello, this is Ava with Think Crucial.

There are a number of reasons why your brush roller has stopped moving. General maintenance to your vacuum is crucial and will help it work at peak performance.

First things first lets focus on the brush roller. Unplug the vacuum and turn it on its side. Look for any noticeable clumps of debris or hair strands that may be caught in the brush roller. Remove these obstructions, probably best to do so with a scissor if it's hair or long pieces of carpet fibers. After removing the debris try manually rotating the brush roller to uncover other hidden clogs. Another thing to take note of is the condition of the bristles on the roll itself. Are they loose or worn down? These are signs that your brush roller is in need of replacing.

While checking out your brush roll you might as well take a look at your vacuums belt. Your belt should be replaced about every three months. After regular usage, the belt will stretch out, lessening the tension on the brush roller. Lesser tension diminishes the brush roller's turn rate and speed. If the belt feels loose then it certainly is affecting your vacuums suction as well as your brush roll not moving at all.

The brush on this model is controlled by the on/carpet/floor switch and will only work in the carpet position. If the suction motor is running then it could be the roller brush motor, but it's more likely to be the microswitch which stops the brush motor when the handle is returned to the upright position.

EITHER THE MOTOR BRUSHES HAVE WORN OUT, OR THE BELT IS SLIPPING.

Buy the brush over the web etc..

To take the brush out
1 - Take the outer covering - uese a penny to turn the yellow srews

2 - Slide the black brush out from the assembly - Try the non belt side first.

3- Slide the belt out of the brush.

4 - Take brush out - Replace it with new one.

Usually, shen you have this problem, there is an obstruction of dirt etc. somewhere in the suction path.
You need to take the vacuum apart and clean thoroughly first.
Then get back to me.

It sounds like you have a roller problem. This machine has a carbon fibre roller suspended on plastic end caps. When dirt and hair etc. gets in and damage the bearings, the belt will be the first thing to go. If the roller is noisy, that indicates that it is off centre and is rotating unevenly. You will probably have to replace the roller.
Take the belt off and rotate the roller slowly and observe the ends. If it is off balance, it will not rotate evenly. The plastic caps unscrew to reveal the brngs and usually you will find hair and other junk gumming up the works. If the roller is damaged, you will be able to see melted plastic and chards of carbon fibre there.
