Great refill for great product!
The Eufy Official Accessories, 6-Pack Large Capacity Dust Bags Compatible with C20 Omni Robot Vacuum provided a perfect fit, and we couldn't be happier with the quality and performance t. The fit was perfect, and the bags were easy to install. Just pop them in and go! Each bag holds an an amazing amount of debris, and I've noticed much less dust escaping. If you are looking for a reliable replacement that works just like the original, these are a great buy. Highly recommend!
