Agree with Turbomaster1984 here-Bring a vacuum such as a Kirby,metal Royal upright,Riccar/Simplicity upright,Sanitaire,Hoover Convertable-those salt grains would be DANCING up off the floor even with one of those vacuums several inches away from the pile of salt.Unimpressed--don't see much going on there.The Dyson doesn't have the vibration,sweeping,and air movement those other machines have.
