Maytronics Models - Active, S, Nautilus, Nautilus Plus...choices are hard!

I've been emailing Margaret with Marina about a robot for our (to be built) pool this fall. Have it narrowed down to these 4. Is the swivel something you need/want? Cartridge vs basket - big differences or just personal preference?

Pool is an 18-36 vinyl rectangle with 6" radius corners and a Fiberglass Roman 11' stp at each end.

Get the S200.
You want the swivel, the basket filter and the additional mesh basket liner that fits inside the pleated filters. This basket liner is included with the S300 models but also works with the S200. Margaret knows.
Note the ports on the side of the S200 this pushes the unit along the tile line, you want those.
If you need the cart, more bells/whistles or desire the option to drive the unit with bluetooth then go with the S300 or S300i.
