When the Cyclone Assembly on the Dyson is not spinning around, it usually means that you are loosing suction somewhere. This can either be caused by a clog, suction leak, or dirty filters. I will give
you detailed step by step instructions along with pictures on how you

left hand side behind the roller brush you should see a flexible
hose that goes from the motor to the agitator housing. This hose
has a lot of strain on it when the vacuum cleaner is in the vacuuming position with the handle down.

Possible Problem #3. Dyson's in general are prone
to clogging. There are a few clog ports throughout the vacuum cleaner
that were added
there due to Dyson prototypes becoming clogged at these points. Here are
pictures of how and where to check for these clogs. Simply remove the
port covers at both of these locations:
Possible Problem # 4. The Dyson DC07 has two filters on the vacuum. The first filer is the pre-motor filter. This filter is located on the right side (if you're standing in front of the vacuum) underneath of the of the cyclone assembly. There is a filter catch that holds the filter and the filter bracket in place. Simply press the filter latch, and remove the plastic circular part that comes off. In side of this plastic part you'll find the pre-motor filter. This filter is washable, but if it hasn't been washed recently, this could be the source of your suction loss. Here's what a clean pre-motor filter looks like, compared to a dirty filter:
The second filter in your Dyson is the HEPA filter. The HEPA filter is also known as the post-motor filter, or it's located after the motor. This filter typically doesn't have any effect on the suction, but you should periodically open it up and take a look at it. Despite the bogus claim of a Lifetime HEPA Filter. As you can see in the picture below, this filter gets filthy. When this filter is this dirty, it prevents the air flowing through the filter, which causes the air to look for other ways to escape, causing the dirty air to escape unfiltered. A dirty filter can also take away from the life of the motor. Here's how you can access the HEPA filter.
First remove the dust bin completely from the vacuum cleaner. Take a flat head screw driver, and right where the dust bin was sitting you'll see a groove. Put the flat head screw driver, and pry this groove off. Here's a picture of that:
Also on both the left and the right side, there are two more grooves that need to loosened before the filter can be removed:
After loosening three grooves, one on the front, left and right sides, the HEPA Filter cover can be removed. Inspect the filter to see if it's dirty. Here's a look at what a dirty filter looks like compared to a brand new filter:
