We acquired this pseudo marvel in June 2008, shortly after its release. 2100 euros to pay, it hurts, but we say that that price, you buy quality and especially sustainable. Now, it is absolutely nothing. While the robot is effective and well cleans walls and water line ... but it is still necessary to work! We met a multitude of breakdowns and problems with this article, fortunately for us, within two years of warranty. So we could get it fixed for free and then, before the evidence of the fragility of the object, we opted for a systematic wintering to a specialist. (With the objective to keep the robot as long as possible). Result, after 5 years only: HS robot, dead engine crawlers to change. 1300 Repair euros (because the parts are absolutely overpriced at Zodiac, planned obsolescence and consumer society requires). The engine did not take water, the robot seems new appearance because we have always been very careful not to damage it. This is just normal wear and tear, as the pool maintenance. Nothing extraordinary, since the parts are apparently plastic and assembled in China! And again, we are informed that we were lucky because another unfortunate buyer of this article has seen the engine let go after 2 years (900 euros to change the engine), the security stopped working and refused Zodiac to make any commercial gesture. In conclusion, we have now decided to flee forever the Zodiac brand, and we turned to a basic standard: the Dolphin Diagnostic 2001 Little expensive and seemingly solid and sturdy. (And spare parts are more affordable so we can get it fixed). I specify that it is only an opinion extremely disappointed average consumer, and in any case a dummy notice of a commercial of a competing brand. I wish I had read a review like this before disbursing 2,100 euros in the air ... Do not be fooled by an alluring design and a falsely prestigious brand ...
