Works well!
If you have Omni S1 pro this is everything you could ever need to maintenance for it! I have it run twice every night and you can’t beat $60 to have several repairs several times! Totally worth its money and fits exactly as if bought new!

Genuine parts that keep my S1 Pro running like new
Fit & Quality: Everything fit perfectly on my Eufy Omni S1 Pro — the rollers snapped right in, and the filters matched the originals exactly. You can tell these are genuine Eufy parts, not knockoffs. Performance: After swapping the brushes and mop roller, my vacuum immediately started cleaning better again. Suction improved, and it picked up fine dust I hadn’t noticed before. Ease of Use: Installation took less than ten minutes. Everything comes sealed and labeled clearly, which makes it simple to replace parts without guessing. Value: It’s a little pricey compared to third-party kits, but the quality and compatibility are worth the extra few bucks. Verdict: Solid replacement set that restores performance to like-new.
