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!

Great value pack
Style: 28Pack Eufy Omni C20 Accessories
I've used each type of item in my vacuum and they all work just as well as the originals. The fit is precise and they last just as long as the original items. It's a great value pack and I love that I have so many extras in the house. I did ding one star because the included screwdriver is the wrong size to install the side brush. If you aren't paying attention during installation you could easily strip the screw. The other items are very easy to install.

Solid Purchase
Style: 28Pack Eufy Omni C20 Accessories
Fits perfectly for my Eufy!
My only suggestion would be to include the little filters too.

Great replacement parts
Style: 28Pack Eufy Omni C20 Accessories
I love my Eufy floor cleaning robot. This replacement parts kit is just perfect for keeping it running perfectly. I am so happy that someone has made cost-friendly options to help keep it that way. This package of 2 Main Brushes, 6 Hepa Filters -( also known as dust filters), 6 Side Brushes, 6 Mops, and 6 Vacuum Bags should keep you going for about 6 months in an average sized home.
