Well, update on Kreepy Krauly - Legend. Still going strong but the bag is showing wear. The velcro on the end is getting frayed and needs replacing. Looks like I could sew new velcro in the top as the bag is perfectly good or replace the bag for about 25 bucks. The wheels are still good but I did exchange the fronts ones for the rear as they had more tread left. All in all the unit seems to continue to function well. The bag seems to be the item needing replacement but I have heard that they usually last only about a year. Still, I think that sewing new velcro on the end is doable to extend it's life. All in all I think the unit is well made and performs it's job very well. Bottom of pool is always clean - leaves and sand (from crumbling flag stone pool edge) are all picked up. I still recommend this pool vacuum.
