Huge believer in the Maytronics Dolphin robot cleaners. 90degree angles are a bit tough on any cleaner - mine are more rolling angles than right angles. Climbs walls to waterline and brushes well. Saves 90% of the labor.
I can drop it in on a weekend morning, go back in the house and have breakfast with my wife and do some quick chores fire up the blender for drinks and my time is effectively doubled. :cheers:
Old thread but... While looking for new filters for my GREAT Dolphin Z5, I see that Epic is selling them for even less than mentioned in this thread 18 months ago. Zionks!
