I am in nearly the same position as miles267. I'm torn between the Dolphin Triton (or Triton Plus), the s300i, the m400, or the polaris 9550. I like the tritons, s300i, and polaris for the easy top loader basket each one has. I like the polaris and m400 for the split brushes up front, rather than the longer single brush. Haven't read any research on the difference there per se, but my intuition tell me the split brushes scrub more than the single. Have no idea where I'm getting that from....
I have a lot of trees in the yard (several crape myrtles which drop leaves and flowers, and shed bark occasionally, and a large elm as well), and am worried about the smaller capacity of the m400 in getting to all that debris.
Anyone have any experience with the triton or triton plus? Here's a pic of my pool as well. Have some steep walls in deep end that will need climbing. Looking to eliminate the need for pool boy, aka me....just want to sit back and enjoy!
The reason for the split brushes on the Polaris is due to the drive system and turning, the brushes are driven by the front wheels so when it turns clockwise or counterclockwise the brush on the turning side changes direction.
