Not compatible with eufy Omni C20.
Style: C20 Parts * 19pcs
The filters are too small. To avoid dust laden air from just going around them I put pieces of paper around the edges as spacers. But they're also shorter too. No chance of a reasonable seal.
Then the vacuum bags are the wrong size too. The robot gives me an error message saying "no vacuum bag is detected". The mop still works, but no vacuum action.
I only bought this kit because the one I was using (that works) was temporarily unavailable.
Never again.
