I finally pulled the trigger on the pool blaster max. I have been looking for something that I could easily stick in the pool and suck up that nuisance stuff on the bottom with out going through the hose dance. It arrived today. I gave it several hours to charge. I turned it on an stuck it in the pool and got rid of that little bit of crud. I am very impressed. At this moment in time I am thrilled with this purchase. I considered a robot but then looking at the minimal amount of stuff to clean it looked like more of spot clean job and not a full pool sweep.
