Check the brush roll ends, make sure they turn freely, if not then replace it. The belt may look ok, but they stretch after a short time and should be replaced.

SOURCE: Brush roller won't turn

Hi.

Your Dyson will have A clutch unit this engages the brush roller when you pull the handle back to vacuum.

Check the clutch control knob which is at the bottom left side of machine looking from the front rotates to drive position when handle is pulled back.

If it doesnt turn the knob by hand to drive.

If you still have no brush rotation after doing all this then either the clutch is faulty or the second belt which goes clutch to motor has snapped & will need replacing.

There are service manuals available for these repairs at this site

Or from Ebay.

SOURCE: Vacuum has lost suction

Check the throat of the vacuum head where the air is sucked to the filter box. Check that it is not clogged.
