Great value for the money, nice to have on-hand

Style: C20 Parts * 19pcs

This set is great and is an affordable way to keep my eufy Omni C20 Robot Vacuum ready to perform. I run my vacuum in about 500 sq feet of my home at least twice a day. Having all the consumable pieces I need (minus the soap for cleaning the floor and the actual water to fill the tank) on-hand makes machine maintenance easy to do. These pieces are easy to change out, too, and the installation was easy as well. I don't have great hand strength but nothing was too hard for me to change myself.

Bad fit

Style: C20 Parts * 19pcs

The dust bags do not fit properly. You can get the base to acknowledge them if you place them just right, but any little movement can move them out of place. I have to constantly reseat them because the base thinks there is no bag. The stock bags do not have this problem. Edit: It has gotten to the point where it is constantly flipping between registering and not registering the bag. Changing to 1 star because they are unusable. If I'm not there to fix it, the task fails every time.
