I am preparing to board out my loft having recently fitted a new hatch,
I was thinking of cleaning up all the black nasty dust which is sitting
underneathth the insulation as there is loads of it and I think it must
be quite a weight on the ceiling.

I have heard some people talk about using Earlex vacuum cleaners from
MachineMart, a mention of someone using a Henry and someone else
mentioned a Combivac wet n dry cleaner?

I think my normal Panasonic bagless one would get all clogged up with
this stuff.

What is the difference between something like an Earlex and a domestic
cleaner? Asda do a cheapo bagless cleaner for about 30 quid or so. If I
got an Earlex would I need to get lots of bags and throw each one away
when it got full?
