Is your home ready for its close up? That’s the question Swiffer and Angelo Surmelis, host of “Rate My Space” are asking as part of the Swiffer HD Clean Challenge, a nationwide search for rooms that meet a new standard of clean. Entrants will be eligible to win a year’s supply of select new and improved Swiffer HD products and an in-home visit from Angelo, captured in an on-air vignette.
