Review on 🔍 Fette Filter 3-Pack Pre-Motor HEPA Filter Replacement for Shark ION Robot RV700_N RV720_N RV850 RV851WV RV850BRN/WV Vacuum Cleaner | RVFFK950 | Compatible with Shark IQ Robot R101AE Series Vacuums by Christy Ghosh

I have used them in my Shark Ion RV1000 robot and they work great. This is the pre-nav you should clean up. They have been on 1 filter in my car for 3 months. I can shake off the dust just enough to see the light when I look into the light. The filter slides into the groove just right and the rubber on top seals the filter so it doesn't get into the engine at all. I drive my car 3-4 times a week and love it. After checking it out today I'll probably change the filter after washing the bin with water. It looked a bit dark and I don't want to mess up the motor and want it to pick up everything. So I rate these filters positively, saying they work just as well as the original, and the price and delivery speed is much better on the Revain site than the Sharks site. If you keep up and make sure you take out the container every time and use the brush you get and make sure you clean the filter tap when needed, it will last a long time.
