Zodiac MX8 - warranty is worthless

I bought the MX8 from Pool Medics Durbanville, about 18 months ago, with a \3 year warranty\" <br> During this time I had to replace the tracks twice, both the Direction Control Devices, and now they say I need to replace the Top Swivel. All of this is already more than R1200 extra.<br> <br> Every single part that I needed to replace, it was said, that the warranty does not cover that part.<br> I understand wear and tear, but to have replaced so many parts in less than 18 months is ridiculous. This is in a fibreglass pool with no leafs close by.<br> <br> I seems like the warranty doesn't cover anything tat can possibly go wrong.<br> <br> The only good thing I can say is that it does clean the pool very well - when it's working."
