Kreepy Krauly Dominator gears failure

I bought the Dominator roughly 2 years ago and was actually very happy for most of the time. I saw towards the end of 2020 that it kept turning in circles. I opened it, and saw that the gears/shaft on the one side were worn out... I thought that it is disappointing that they wire out almost immediately after the warranty expires. I bought the repair kit at substantial cost and replaced the gears (middle January) and all was fine, only to notice this morning that the gears have worn out AGAIN, two months later!! Surely that must be a design flaw? I can't spend R1000 every 2 months for this!!! Also, I have to buy a full gear and wheel set only to replace 2 components... Would really appreciate answers!
