Every February for a Valentine's Day special, Charlie Mathern of Charlie's Hardware in Waseca, MN runs a special where people trade in their old vacuums for credit towards a new vacuum cleaner. Ron Purcell of Waseca brought in this vacuum that he had purchased at an auction in Kansas. Charlie took the vacuum in trade. Vacuum canister is dented so longer suctions.
