...the good old Hitachi CV-2000 canister?
They used to show it on trade fairs here, demonstrating it sucking up pebbles and old batteries (as lame as a "proof" of suction as this boring Kirby "sucks-up-a-Volkswagen-beetle"). *yawning here*
All of it is just a matter of the ratio between vacuum (or negative pressure, as no vacuum really creates a vacuum) and the surface of it being applied to.
Any vac can do this (both tests, the battery one and the beetle one) as long as the weight/surface pressure is carefully calculated and the rest of the props (suction plunger) are carefully adjusted.
Yet this was a mean little machine, a plastivac in screaming 70s orange featuring a corrugated cardboard filter. The housing could be split in halves: Front being the dust chamber, back being the motor/fan and the cable winder. The funny thing: The cable winder had this little u-shaped wire insert that would rattle along the filter ribs when the retractor was running. Thus the collected dust would fall down into the lower portion of the dust cup. Even the floor/rug tool was 100% plastic.
Has anyone got one of these?
Comes to the Rescue!
