Perfect fit, 11s running like new!
Style: with Pre-Filter
All parts fit perfectly. My vacuum lasts about 20 min longer since the filter isn’t clogging it. Also, replacing the spinning brush quieted it down significantly, it sounds like new again.

GOOD
Style: 28Pack Eufy Omni C20 Accessories
The kit includes several useful pieces and helped me replace accessories I already had worn out. I liked that everything came organized and it was easy to find each part. Some pieces feel sturdier than others, but overall it does the job well and it is convenient having everything together in one package.

Buena calidad precio
Style: 28Pack Eufy Omni C20 Accessories
Precio beneficio me parece un paquete bastante completo para hacer los mantenimientos. En cuanto a tamaño calidad y funcionamiento no hay queja (salvo por del atornillador que es como de mentira y se desarmo al tratar de aflojar el tornillo y no es de la medida correcta).

Excellent Long Term Value & Perfect Compatibility with Eufy Omni C20 Robot Vacuum
Style: 28Pack Eufy Omni C20 Accessories
This set is of great quality and value for the money. It fits perfectly with the vacuum and base station and includes extra tools like a small screwdriver if you need to make any repairs. I love how it functions and provides the user with an easy experience with all the maintenance tools in one kit, lasting for many months or even a year or two with the primary vacuum. I absolutely recommend this product. Everything you need!
