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.

Very Very Good Product
Size: 16 Fl Oz (Pack of 1), Size: 16 Fl Oz (Pack of 1)
The description says ToreTark helps keep dirt and grime away from your vehicle after use. I applied this product on my vehicle November the 9th. Today, (Two Weeks later, without cleaning) November 23, 2025, I cleaned the outside of my Tacoma. I cleaned the driver's side of the truck using dry towels only. The passenger side of the truck I used my favorite cleaning product. ToreTark was easy to apply, the driver's side is still shining with only a dry cloth to wipe it down. The passenger side is still shining although I used my favorite cleaner. The wax quality I can't judge, don't know the appropriate description. All I can say is it is still one heck of a protective shine. I am not a professional car cleaning guru. For the weekend shiners, you will like this product.
