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. No complaints

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.

Mostly fine replacement parts

Color: Omni S1 Pro 17P

I can't get either of the rolling mops to snap into place no matter what i do, might have to tack on something so they stay in place. The main brush was a fine fit, but the side brushes seems more flat than the stock ones and it makes some weird noise now, they did snap on though. Filter was fine though and I haven't tried a dust bag yet, still good value even if I can't get the mops to fit for me!
