Bests & Worsts Reviews from Amazon

AVOID! AVOID! AVOID! I don't understand how this unit or this company got the positive reviews that it did. In under two weeks use, the treads on the unit started to break (see attached images). I contacted Maytronics customer service twice through the form on their website and received no responses. (In fact, at the end of all of this, their customer service manager said I was using the wrong contact method and I showed her that I did exactly what she suggested after the fact.) Having not heard back from them, I called 1-888-DOLPHIN and reached a customer support representative who gave me an e-mail address to send the attached pictures and explain the damage. I received no response for a week. Finally, I called support again to get help with this. After a long and difficult conversation with several of their representatives, their manager said "I have received a response from the Repair Center manager, he reviewed the pictures you submitted and confirmed that this would not be considered a manufacturing defect. Please note the brushes are considered a wearable item and are not replaceable according to the warranty, We are unable to offer replacement assistance." The pool maintenance people that I used gave me a cleaner the year before and I used it in exactly the same way without any damage. This company won't even honor their own warranty.
