Clean(er) House Arithmetic

I always sucked at math but this equation is pretty simple:

1) Add one dog who sheds fistfuls of fur year-round

2) Subtract one vacuum in 2005 (no picture - have some respect for the dead!)

3) Subtract one vacuum in 2006 (no picture - ditto)

4) Add a dash of Dyson (and a 5-year warranty!)

Yep, I'm now one of those assholes. "I'll NEVER pay that much for a vacuum!"  Oh, really? Hmm.
