Well, it's probably about time that my DC11 had a bit of preventative
maintenance, new motor brushes and what not.

However, I'm not having much luck getting into the thing.

I've removed about half a dozen bits of plastic, but the main shell
doesn't seem to want to come apart. I've removed 6 screws, but the top
seems pretty firmly attached to the bottom.

Any ideas?

Doesn't mention yours in particular, but there's probably a number of
generic tricks.

Ah,

Many thanks.

There does indeed appear to be a generic trick:
You have to prise the wheels off. Hiding behind the wheels are 2 pairs
of screws. Remove those and the whole thing comes nicely apart.
