To a degree, yes. It beats having to change out HEPA filters. Personally, I have a Dyson DC13 and it does great for my wife's allergies. Water-based vacuums can be a PITA, and that water gets nasty if you let it sit too long or spill it--all the dead skin particles that compose the bulk of dust in your home start to rot and the smell will stick.
Get a wet-vac carpet cleaner if you don't have one, it really gets the fine particulates out. I have a Bissell Pro-heat 2x and it beats the living hell out of the Hoover models (their brushes are too soft).
And change the filter on your HVAC system regularly! Most people forget about those, and if you see black dust around the vents, that means you're basically blowing dust and dirt around your home and keeping it airborne.
