If you're near Daytona I will find the name of the vacuum specialty store we recently purchased our Simplicity vac from. The lady there was sooooooo knowledgeable and helpful. Even if you don't purchase from a specialty store, I'd go visit and talk to an expert, no one in Target or Lowe's will have that knowledge. We liked Simplicity because it is made in the US, amazingly. I know this gal talked about some that were called sand-machines (or something) that were designed to suck up the sand! We're on the 8th floor in a condo and by the time we get to our place from the beach, most of the sand is in the lobby or the elevator LOL. So I can't personally recommend a sand machine, but just my perspective in buying a new vac recently.

When I lived on the sandy coast of SC, I had special shoe cleaning door mats outside of every door....everybody did. What kind do you have?

I have the shoe cleaning mats, as well (in the house, at each door, and in the trucks). The dogs and cat don't wipe their feet, so I get lots of sand in the house, every day.
