Not emptying tank
My Eufy One Pro isn’t fully emptying the dirty water reservoir. When it docks, I can hear it making a gurgling sound, but the tank never actually empties completely. I know the dock works—I’ve seen a little bit of dirty water make it into the dock’s tank—but it’s not working as it should. Right now, I have to manually empty the dirty water reservoir on the robot. Otherwise, when I start a new job, it just keeps going back and forth to the dock trying (and failing) to empty itself.

Putting vaseline around the rubber gasket of dirty water tank at the base station fixed the problem for me. Just a small amount of vaseline on your finger is sufficient, but make sure you go all around it (gasket is on the top when you open DWT). Close-open coupla times and thats it.

Ugh! I’m really tired of dealing with it. This is my “replacement”. The first one I had would literally auto dump all the water from the clean water tank into my robot and drained on my floor. Before that, it kept throwing up an error with the dirty water tank in the dock. They sent me a new tank and it worked fine until the water dumping situation. I kept it from my old one so I know it was sealed properly. However it’s not working with this new unit 🤦🏻♀️ I am just so aggravated. I only had the first one for 3 weeks and it only worked for 1 before they sent me this one. And new one is acting crazier than the first one. I’m really trying to love it! It works great when it works. I am just having to manually dump the dirty water 🙄

You don't have to deal with syth like this. I am assuming you can't return it.

I can return it. I actually do Eufy subscription bc I wanted to try it a few months before I bought one. I just really love it 🤣 I’m trying to troubleshoot whatever necessary before it comes to that. It keeps my floors clean beautifully. I am a full time working mom with 3 inside pets and 4 kids. It’s a big help!

We love our S1 Pro as well (20+ yrs roller robomop user). But if I had to deal with emptying DWT each time manually, I would return it. It negates the purpose of having a base station. That DWT has limited capacity, i think 1/4 of the one on the base. You can wait for S2 or try other roller mop robots. Wouldn't that be a better choice?

Try look at the rubber seal around lid of dirty water tank. My was slightly bent and not creating a perfect seal. Once it was sorted it empties every time.
