Pool Cleaner Replacement Filter Bag

Have used fine filter bag for over 1 year and it is fantastic in cleaning pool. I have the jet version of Verro Pool Robot and it kept pool clean for the 4 months it took me to get a new pool pump shipped to Virgin Islands - just have to turn bag inside-out and hose squirt off debris and algae it picks up. I have cartridge filters (7) which are $50.00 each locally and this filter bag keeps pool cleaner than pump and filter. This is very economical. I run my Verro 4 or 5 times a week (7 if we have a lot of Sahara Desert Dust (full of dust and mold/algae spores) and electricity cost is only about $0.55 even with our very high $0.37 per kilowatt/hour electricity rates (most of US is below 10 cents).One word of caution, I was so excited when I received my Verro that I put it in a very algae covered pool without cleaning pool the old way first and that really plugged up the bag - but it trained me how to clean filter bag. I would suggest you be a little less thrilled when you get yours and clean your pool before first use.
