Quality has deteriorated

I really don't have confidence in your products anymore. We had a robotic cleaner and it kept needing new rubber brushes and rubber tracks every 8 months or so. After spending money on it over and over again we decided to just replace it with a standard kreepy. But this kreepy from the get go keeps getting stuck for no reason. You jerk the pipe and then it starts moving again. We've only had it a few weeks. The quality of your products has dropped. It may be time for us to consider an alternative.
