Contact UsThis is my second Dolphin. I had a Triton before and my impression of the Sigma is that it is a massive upgrade over the Triton... The cord swivel alone is huge, I no longer need to worry about the robot getting tangled in its own cord. Also, the top stabilizer arm prevents the robot from flipping over when cleaning steps. I have just put it in the pool for its first cleaning and have had no issues with it getting stuck on the main drain (though my drain cover has a gentle slope). I will update this review more as I gain more experience with it UPDATE - I have been using this for the past week and it does an excellent job of filtering the fine dirt off the bottom of the pool using the ultra-fine filters included in the package. The construction of the filter assembly makes it much easier to clean out vs. the Trition and it is a snap to switch between the normal and ultra-fine filters. I have had no issues with the robot getting stuck on obstacles or flipping over.
