Perfect Fit & Performance
Style: with Pre-Filter
These are an excellent, cost-effective alternative to OEM parts. The brushes and filters fit securely, restore full suction power, and hold up well to daily use. A must-have for maintaining a Eufy RoboVac without the high brand-name price tag.

Works great!
Style: with Pre-Filter
I bought this set to put on my original euphy robot vacuum. It works perfect! All pieces fit perfectly and were so easy to change out. I’ve had the new parts installed for a few weeks and it works so much better now. I recommend them for sure if you need any new parts for yours!
