Review on 🧹 Enhance Cleaning Efficiency with the BettaWell Replacement ECOVACS Robotic Cleaner by Cara Ruiz

I bought some of these in April 2018. They worked well and I was able to keep them clean and in good condition for two years. Just bought two more in September 2020. Both rollers are out of order and no longer work. The plastic tab that fits into the vacuum's square hole to rotate the roller is broken. The plastic rotates, but the metal shaft it's connected to doesn't move. In other words, the inside of the plastic has ripped off and will no longer spin the roller.
