I'm new here also... what a great site!! I am also narrowing my search like dmrap to the Dolphin brand. However in researching this I am getting more confused. This thread started asking about the Premier model(sold by poolexpress). When I looked at their ad they make it sound like the M5(cartridge filters) but going over the the Maytronics site it looks exactly like the DX6 which is a bag filter. Their add also says it is a modular constructed cleaner and easy for the owner to do the repairs?? I don't see that claim at the Maytroncis site.
Also on the poolexpress ad for the premier they claimed you can put a filter bag on for larger debris... but I don't see that either at the Maytronics site because they talk about the DX6 as a bag machine.
So bottom line is if I try to buy one of these under a unique dealer name I am not sure what I am really getting. Does Maytonics do more for these unique dealers than slap a different name and maybe color on it??
Sorry for rambling and thanks.
