Man, if you consider slipping a bag over wire guides and clipping it into place "tuff, hard, or difficult", then I think you may have the wrong impression on the Dolphin.
I can pull it out of the pool, flip it over, remove the bag, dump the sediment,
rinse it off and re-install in about 5 minutes.
Thats the amount of time it would take me to pull my Hayward Navigator out to remove the small stone, acorn, or leaf that would make it in operable.

Go for the Dolphin....not difficult at all. Its not pool season yet, but do to constant rain, I run it about 3x a week using the porus leaf bag.
