<P> In 1990 after growing frustrated with ordinary mops, Mangano developed her first invention, the Miracle Mop, a self - wringing plastic mop with a head made from a continuous loop of 300 feet (90 meters) of cotton that can be easily wrung out without getting the user's hands wet . With her own savings and investments from family and friends, she made a prototype and manufactured 100 units . Early assembly was done in her father's body shop in Deer Park in 1991 . </P> <P> After selling the mop at trade shows and in local stores on Long Island, she sold 1,000 units on consignment to QVC . It sold modestly at first, but once QVC allowed Mangano to go on - air to sell it herself, she sold 18,000 mops in less than a half hour . Mangano incorporated her business as Arma Products, later renaming it Ingenious Designs . She sold Ingenious Designs to USA Networks, the parent company of the Home Shopping Network, in 1999 . By the year 2000, her company was selling $10 million worth of Miracle Mops per year . </P> <P> Huggable Hangers--velvet - flocked, no - slip hangers whose thin profile conserves closet space . Endorsed by Oprah Winfrey, Huggable Hangers were HSN's best - selling product as of 2010, with more than 300 million sold . </P> <P> Forever Fragrant--a line of home odor neutralizers including sticks, wickless candles, scent stands, finials, spheres, drawer liners, and shoe shapers . Mangano broke an HSN record on January 31, 2010 by selling 180,000 units in one day . The Forever Fragrant line has won the Good Housekeeping Seal of Approval . </P>
