This is 'Big Brute'; a member of Philips re-enamelling and conversion team! We use him to suck all the old insulation out of Aga range cookers; he is the worlds biggest and most powerful vacuum cleaner.
Cats, small dogs and pets must be removed from the vicinity before use (seriously; it's in the instructions) in case they 'disappear'...
With 20metres of hose we can leave the unit outside and create almost no dust in your kitchen. 'Big Brute' is an expensive bit of kit that requires frequent maintenance but without him our 'work clean' philosophy would not be possible! You are probably sceptical; here is a customer of ours on the mess that we left!
