I receieved my Seagull Pro on Monday. I previously had a Dolphin unit. My pool is 16x32, very small in comparison to the advertised sq/ft. I charged the unit and ran a full cycle in auto mode. The unit did pick up some debris, but left a significant amount behind. I charged it again and ran it in auto mode for a second time. Again, it left a lot of debris behind. Most of the debris was in the crevices of the pool, but there was also a significant amount left in the bottom of the shallow end. Please refer to the pictures.
I reached out to Aiper because I thought I might have a defective unit and they simply said that the unit is not good at cleaning in crevices. They didn't comment on all the debris left in the shallow end.
The only thing that I have to compare this to is the Dolphin unit I was replacing. The Dolphin unit cleans much better in one cycle than this unit did in two cycles. The Dolphin never left any debris behind. I have decided to return the Seagull Pro and purchase another Dolphin or similar unit.
It seems as though others are having good experiences with the Seagull Pro, maybe I did receive a bad unit. However, I wanted to share my experience to help others that are looking into the Seagull Pro. I was really hoping this would clean effectively, because I love the cordless design. That said, I would much rather have a corded unit that does the job effectively than a cordless unit that requires multiple runs in addition to manual vacuuming. My two cents.
