At last here is the key to Dysons. Bought DC01at a boot sale 5 years
ago for =A320 and use in my woodwork shop for all that dust. If i suck
up the big shavings by mistake i use a piece of metal rod to push out
of bottom chute. No hoses to flap around and empties in seconds. The
filters - blow out with an air gun - so simple. And easy to repair, the
cable was eventually pulled too tight at entry and repaired in 5 mins.
As a designer myself I can appreciate every design detail.
