There are several things that this could be. Probably the most common problem that we see when customers come in with this problem is actually a fairly simple problem to fix. Here are just a few things that this could be.
The fist possible problem sounds like the most probable to me, just because of the fact that you said you had just replaced the clutch, and therefore you had to remove the bottom sole plate. This is a VERY common problem actually.
#1. The first problem is extremely common. In fact, we probably see
between 2-3 of these problems every week. It mostly happens after people
take the bottom plate off the vacuum in order to clean the roller brush.
is when they reinstall the bottom plate, they put it on on
incorrectly. It's actually very easy to do. When the bottom plate
(soleplate) is installed wrong, there will be a gap between the bottom
and the agitator housing, or the purple tray the roller brush sits in.
This will cause the
soleplate to be a few inches higher off the ground then it should be,
preventing the brushes from even hitting the carpet. This makes it seem
the user that vacuum has lost suction power because without the brushes
the carpet, the machine will not pick up very well on floors, but when
they use the
attachment hose there's plenty of suction power.
Here's a picture
of the WRONG way to install the bottom plate. Notice the gap in
between the two housings:

Possible Problem # 2. Turn the

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 reclined

just remove the entire hose assembly by pulling on it. It will easily

also explain why the vacuum works fine when using the attachments, but

If you do
find a crack in this hose, the this hose needs to be replaced. Here's a

Possible Problem #3.
I would suspect that this may not be the problem, but if neither of the
worked, then try this one. 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:
If you are getting suction power from the hose, but the vacuum still doesn't pick up on the floors, I think that these solutions should fix your problem. If you just replaced the clutch mechanism, the roller brush should be fine, but turn the vacuum over on it's side and make sure that the roller brush is actually spinning while it's on carpet mode.
