Works just as well as the official parts, for less
Color: Omni S1 Pro 17P
Been going through these for about two years now across multiple replacements and they perform just as well as the official Eufy parts. Main brush, side brushes, filters, dust bags, mop — all fit correctly and do the job without any issues.
Honestly if you’ve got a Eufy Omni S1 Pro, just buy these instead. No reason to pay extra for the official kit when these hold up just as well over time.

Not a good fit with the eufy
Color: Omni S1 Pro 17P
It’s a good value for all these pieces, but the dust bag does not fit well with the Juvi. I haven’t tried the other piece pieces. I will return it.
