I was hoping to get through this summer before buying a new pump ... but looks like the time is now!
Our current pump is only 3/4 hp and I've never had issues with not having enough suction - although I really never have to use the vacuum due to the location (I really don't battle with tree debris etc. Our robot generally picks up everything and if not I just grab a net. Also, I generally get away with running the pump for 8-12 hours a day in the summer, and I've never had algae issues as long as I keep up the testing regimen.
Due to this ... should I even consider a VS? I've looked at some pumps and it seems that the HP is the only specs given without really digging into owners manuals ... is there anything I need to look at?
