New suction vacumm

[JCJR55]

I currently have a Navigator concrete going on 8 years. I use a 2speed pump on low but the navigator needs alot of suctio too climb walls.

There is a sale today for the M8 but on Amazon there are a lot of mixed reviews. Can anyone recommend a good vac?

(Sorry, I can't help with your question: my experience with suction side auto pool vacs is very limited.)
