Highly impressed after using this in my new home for several weeks. She saves me 1 1/2 hours a day keeping up on my floors-2700 sq feet, mostly laminate wood but I love walking into my primary bedroom and seeing her vacuum lines too! I get maid service daily!!! Still have to do edges, corners and be hind doors occasionally- but I wouldn’t be without my “Rosie Jenson” IYKYK😊

fits and works for s1 as well

Size: 16 Fl Oz (Pack of 1)

I bought this for my omni eufy s1, and it fits. For some reason it doesn't confirmation of it clicking in place. But it has the same exact size and shape as the one being sold for exclusively for the s1. All you have to do is take off the stick, push it down, and then push it in. So it fits, it just doesn't give auditory confirmation when you're putting it into the base station. Which is weird but whatever. I got this because it was $4 buck cheaper then the other one they're selling.
