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!

Good quality overall
Color: Omni S1 Pro 17P
Good kit I ordered for my S1 Pro. All of the accessories seem to be of good quality and have held up well over time. Order without hesitation.
