Dssxxx, sorry but you've got it all wrong ! Maytronics (Dolphin) is owned by a Kibbutz, owned by all the members who live there , this is the Kibbutz's business which is their main source of income, Aquabot was started by the US rep for Dolphin, who went on his own .Watertech(Blue Diamond) is owned by the son of Aquabot , Aquabot and Blue Diamonds are made here in the US , Dolphins are made in Israel.To prove your info incorrect you stated you got yours from Aquabot factory and you haggled with them ??? In another post you stated you got yours at Aqua Distributing, that is not owned by Aquabot, they are just a distributor, Aquabot will not sell direct to consumers , neither will Watertech(Blue Diamond) or Smartpool (Dolphin) !!!!
