Check Filter size

Super close!!! Image shows what is in the package. Look closely at the filters if you have an 11S. In my photo, their parts are on the left and my pieces are on the right. The brushes and roller and retainer fit. The filters don’t fit. Model 2126

Bought for my euify robot vacuum. The replacement parts fit perfectly. They are exactly like the original one parts. They are long lasting. I have dogs and they get used every day.

Finally somebody got it right!
Size: 26 Pack
FINALLY there's a parts replacement kit for my Eufy 30C robotic with quality parts that actually fit! And a roller brush that's substantial and bristles that aren't too short to actually reach the floor! After being disappointed in so many others, this is the perfect one!
