After experiencing a huge disappointment with a Zodiac cybernaut NT (Priceless, all the time down, irreparable because of the price of spare parts, short, rip off), we opted for the basic home Dolphin, determined to boycott indefinitely the Zodiac. Well we are not disappointed! Besides being cheap, the robot does a very good job: it goes everywhere and cleans the walls and the water line, it seems robust and above all, spare parts, at Dolphin, are affordable so we can fix it without having to change it to any failure! Only constraint, but it's the same with the cybernaut: you must clean the filter bags. But it gets there very well with a little practice. No need to spend more, you've got the best value for money for a pool cleaner.
