I have been looking around for a cleaner and am wondering what the difference between the 2 models is. From researching on here I found that the Premier is only sold at one place, but could not find anything about the differences. It looks like the premier offers the ability to change filters depending on whether there are a lot of leaves in the pool or not, and the M500 does not offer this. What is the advantage of the M500.
What about the supreme liberty, does the battery hold up and does it have the same power as the corded models?
