We have a Dyson and a Henry at work.

We have both at home.

In the case of the Henry, the suction drops off very quickly after
changing the bag.

In the case of the Dyson, bits drop off very quickly.

I have a DC04 which was not bought for building work, but at 4
years old now, that's all it's been used for, and it works
brilliantly for it. I am careful not to bash the thing around
and no bits have dropped off so far. I did break the cuff on
the end of the hose when it was new due to dropping something
heavy on it, but Dyson sent me a new one FoC. Amoungst other
things, it's vacuumed up the rubble debris and dust from demolishing
an internal plastered brick wall (a wheelie bin full, actually too
heavy to move the bin;-), and from stripping the plaster off several
other walls, taking down a ceiling, coupling up to planers, circular
saws, and wall chasers for dust extraction, etc. The only obvious
sign of abuse was the clear dust container was internally sand
blasted from the first job, but that hasn't had any effect on it's
operation.

I've tried using a wall chaser with a Henry, and it doesn't work.
It blocks the bag in about 10 seconds, and without a bag the dust
mostly all passes straight through the cleaner and comes out as a
thick cloud. A VAX with an inch of water in it worked slightly
better than the Henry. On one occasion I hired a wall chaser
I was offered a large industrial cyclone cleaner and told that
worked very well, but it cost as much again to hire so I didn't.
