We just switched to Pink Flamingo.  I had a few cleaners over the past 7 years here and one for the past 3.  I cannot tell you how great the difference is in my pool only after 2 visits!  My former pool cleaner serviced my pool weekly for about 5-6 minutes each week!  Are you kidding me ... spending the same amount of time at other residents' homes.  Not enough according to experts.  Norm (owner of Pink Flamingo) is excellent!    In many years, our pool has never looked as clean as it does today!  And this includes the tiles!  I highly highly recommend Pink Flamingo. - Audrey S.
