Check Filter size
Size: 23 Pack, Size: 23 Pack
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.

Bought for my euify robot vacuum. The replacement parts fit perfectly.
