My house came with an already old Henry 24 years ago, the most expensive ‘hoover’ ever. It’s still going well, but for the shed/workshop only, not the usual household stuff. Henry picks up dirt, crud, damp stuff, missing bolts from my bike, bits of garden, coal dust, never clogs. It doesn’t do it brilliantly, still works when it falls over – it just keeps on going. Hose taped up with gaffer tape, various add-ons held on with fingers crossed. Sorry, I can’t answer the OP’s actual question…
