Very good product for the price - the front brushes wear fast compared to the original Eufy’s but for the value you do get a lot of product. So only 4 stars but just for the brushes “appearing to not last as long and bend but the buy is worth the extras. The filters look and work identical to the OEM. Good stuff - thanks!

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).
