I have been trying to get a whole lot of gunk out from the bottom of my pool. My new purchase, PoolMaster Max CG arrived yesterday and got charged and used today. I was so dubious about it, partly because of the high price tags, but it is doing the job. I am gong to vacuum again tomorrow and I'm hoping that will do the trick. Yahoo! Now to get the chemistry under control. I may get to swim soon.
First picture shows deep end after about half the silt had been vacuumed; second shows part of what came out of there; and the third shows the (almost) clean result.
