Bang for buck

You get a lot for the price. And it fits. Recommended. It is a little noisier than the original bit functions are the same

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.
