Review on 🤖 eufy RoboVac Pre-Filter Replacement - Compatible with RoboVac 11S, 11S Plus, 12, 15C, 15T, 25C, 30, 30C, 35C, R450, R500 - Essential Accessory by Kristin Anderson

I almost sent these replacement pre filters back thinking they weren't the ones in my Robovac 30. They seemed larger and a lighter blue than the original filters. However, I accidentally (and irretrievably) threw away the original shortly after the vacuum arrived, so I couldn't compare them. I decided to try it and to my surprise it worked perfectly! I'm not sure if I snapped it in the same place, but it seems to work even better than the original. (I found the instructions on how to drain/clean/change the filter extremely confusing. The writing is small and it's hard to tell which side is up.)
