Blue Pearl dead, need advice on new cleaner or a fix.

[kirbinster]

Looking for a new cleaner as my Blue Pearl just died. Came across the Dolphin Primal X3 and was wondering if it would be good for my 20 by 40 vinyl IG pool. How do its filter screens compare to the bag filters that I am used to. Will it climb walls well? Is it safe on the liner. Should I get this or is there something else that is similar and not a lot more than the roughly $600 this goes for. Thanks.
