I've had my Pool Blaster Max for 2 months now and use it every single day. I get three ten minute sessions out of it. When I recharge it, I set my phone alarm so I don't leave it plugged in too long.
I use the micro filter bags. They slip over the original bag. And recently, the original bag that came with it kind of came apart... Like cotton candy separating. I ordered a replacement bag (sand and silt bag for $25). It picks up sand, silt, pollen, rolypolies. It's not so great at leaves. They tend to float away as you approach them.
I use this vac every day before I hop in, because I hate dead insects on the floor of my pool!
For tons of leaves, I have to use my robot in the pool, as the Pool Blaster Max is for small clean ups.
