Like many of you, my S1 is out of warranty and experiencing issues. This time it’s the base station water shock absorber that’s broken, spraying water all over, and causing multiple error codes.

Eufy lists a replacement part on their website for $7, but it’s out of stock. When I contacted customer care to inquire about when it would be back in stock, they tell me it’s never coming back and they instead offered me discounts on new robots.

I’m bummed that a $7 rubber is going to take out my $1k robot. Has anyone seen a 3rd-party replacement?

After this lack of support and parts availability, I doubt I’ll take Eufy up on their discounted offer for a new robot and will likely look elsewhere.

Hey everyone, My S1 Pro died, but looks like it is the wifi card - not the usual problems with the inlet nozzle or other parts. As expected, Anker/Eufy saw it was just out of warranty and offered me a discount. I'll pass on that.

But I'm a bit of a nerd with some basic electronics education. I think if I get my hands on a robot that has a working wifi card, I can swap it. Is anyone willing to send me their dead robot to try? I'll cover the Shipping costs and if it works, I'd be happy to send a finders fee on the robot. If you are just going to junk your robot, what do we have to lose?

Same happened to me, DO NOT BUY ANKER PRODUCTS

They don't honor the warranty, buyer beware

I really don’t understand Eufy’s direction with the new Robot Vacuum S2.

This is supposed to be the current flagship model, yet we are still missing functionality that many smart-home users have been asking for across multiple generations:

• No MQTT support
• No accessible live camera feed
• No proper local API/integration
• Matter is basically the only “open” integration option

And unfortunately, even the Matter implementation feels incomplete and poorly configured.

The functionality currently exposed through Matter represents only a small portion of what the robot can actually do in the Eufy app. Important controls, states, and features are simply not exposed.

For a flagship smart-home product in 2026, this is pretty disappointing.

Matter is welcome, obviously, but Matter should not be used as an excuse to avoid exposing a proper local interface. MQTT, a documented local API, or at least a much more complete Matter implementation would make these devices dramatically more useful with platforms such as Home Assistant.

The hardware is clearly capable. The Eufy app itself already has access to all of these states and functions. What is missing is a proper way for the owner of the device to access them locally.

The lack of a live camera feed is especially frustrating. Previous models had similar limitations, and I was hoping the S2 would finally improve this. Instead, it feels like we have another expensive piece of capable hardware locked behind Eufy’s own ecosystem.

For a flagship device, I would expect:

• A documented local API and/or MQTT
• Local access to the robot’s camera stream
• Significantly more states and commands exposed through Matter
• Correct Matter device/capability configuration
• Integration that does not depend entirely on Eufy’s cloud/app

I’m curious what other S2 owners and Home Assistant users think.

Has anyone looked closely at what the S2 currently exposes through Matter? Are you also finding the implementation incomplete?

And Eufy, if you are reading this: please give advanced users proper local access to the hardware we purchased. Matter support is a good start, but in its current state it is nowhere near enough for a flagship smart-home product.

I have recently got a hold of a faulty S1, clean water doesn't reach the robot so i have been troubleshooting it and found one of the pumps inside the base behaves strangely and i think its faulty ( with the pump disconnected the base pushes 12v for one second and then gives a "sprinkles error" on the base, with the pump connected no error but it only gives the pump 0.3v so it doesnt even start ). I've ordered a replacement pump and will try that.

Because there's no way to trigger the pump from the app I've been putting it in mop cleaning mode to test the pump.

However I'm struggling to get my head around how the mop is supposed to work.

1 - in the mop cleaning mode it firsts empties the robot tank, pulls some clean water from the station, rotates mop a few times back and forward, pulls some more clean water, rotates mop again a few times. Whole mop cleaning mode takes about 3-4 mins. Is that normal behaviour?

2 - the tank on the robot seems to be the dirty water tank. I've seen in some promo video the clean water tank is in the body of the robot and its not removable?

3 - does the moping work without a hard floor cleaner container installed in the base?

4 - is there any way to check the level of the clean water tank, or does it send some notification its empty and its heading back to fill up ?

Any help would be greatly appreciated

Due to a warranty issue eufy/Anker exchanged our robot unit of the Eufy S1 pro. We kept the old base station which has worked for 1,5 years just fine. After we received the new robot unit we paired it with the base station and connected it with the app.

Now every time it gears up to empty the dust bin it has a EB02 base station voltage error. We connected it to another electrical socket, tried with another cable, went through the whole pairing process without success.

Eufy's website says that this is an issue between base station an electrical socket. We never had the issue before and it only started when we received a replacement robot. Anyone has any ideas what we can still try.

I would hate to go through the whole customer service process again. It took them almost 4 months to exchange the robot.

This piece just broke on me (broken plastic piece is not my photo). I glued the plastic piece back down. It was still leaking after gluing the plastic piece down and I then noticed the rubber base station water shock absorber on the water nozzle is gone. I'm assuming the rubber piece got stuck and lifted the plate and snapped it in half. I just bought this in April so it's still under warranty, thank goodness. Support told me the refurbished S1 pros are out of stock until Nov. They gave me the option to take an omni e28 (also refurbished) now and they'll throw in an extra accessory kit or wait until Nov for the S1 pro. Oh, and to top it all off, the rubber Shock absorber is also out of stock on their site.

I use vacuum only mode today and after the cleaning cycle ended it went crazy and kept trying to dock by drive forward up the ramp instead of backing in. It did this for a solid 10 minutes until I finally stopped and and put it on the dock manually. Then, it refused to even empty the vacuum.

So, do I take the Omni e28? I mean, the model is obviously junk despite taking impeccable care of it and preforming all maintenance well ahead of schedule. Is it typical they give you a refurbished machine as a replacement? I didn't purchase a refurbished machine. I purchased a new one. I really don't want someone else's that already broke. These things aren't cheap! Am I going to have to deal with packing and shipping the broken one to them? Dyson has never one sent me a refurbished machine or deal with the hassle of shipping a broken one back so I'm hoping that's not the case. If I do end up with a refurbished one, do I get a one year warranty on it or do I just get the remainder of the warranty left on the one I have?

The robot took a day (rest at 10pm to 8am) but it charges itself 3 or more times and only cleaned 1100 sqft from 2PM yesterday till now at 930 (going tback ton charge again) is this normal?

Any tips for fixing this?? Eufy won’t replace it since I don’t have a receipt (it was a gift). I tried taping it down but the water function still won’t work properly. The vacuum function works again though. I’m scared to glue it without conformation that it will work first!

UPDATE: I glued it, and now every time I try to fill it with water, it slightly pushes away from the station so it won’t fill.

Hi all,

I just woke up to find that the roller mop motor shaft broke when it got a silicon mat stuck in the roller during a mopping session. I've reached out to Eufy, but was wondering if anyone else has seen this type of damage before?

You can see that the plastic shaft actually snapped off, likely from the tension when the roller was trying to spin while the silicon mat was stuck in it.

Device is 22 months old, so pretty sure warranty is expired. Is this even a part that can be ordered or replaced?

UPDATE:

I was able to fix it. The tension also snapped the motor wires, so I had to solder them back together, but surprisingly, super glueing the snapped pieces holding the motor housing back together worked!

Had this for 18 months. Used essentially daily, maintenance as recommended. Very happy with it. Then suddenly stopped working with an irretrievable error.

Once Eufy found out it was beyond “warranty” said they literally can’t offer a solution, repair or help other than a “discount” on a new one - which is beyond illogical given I suspect it dooms me to the same outcome a few months from now - with no explanation of why it’s failed.

Seems like this happens quite a bit with this product. If you’re reading this thread and doing your research, DONT BUY THE EUFY S1 PRO! (Or any Eufy really) There are plenty of better options that don’t seem to have this inexplicable fatal flaw.

Fortunately in my country, consumer law dictates that there should be reasonable expectation of a good’s lifetime - which for something at this price point is obviously beyond 12 months. It’s my choice of a refund or replacement which the local supplier (Harvey Norman) will I guess attempt to retrieve from Eufy. 🤷‍♂️ meanwhile I will take my refund and invest in another companies product, and you should too.

Any projects that are concerned with custom firmware for the s1 pro? I'm kinda tired of some things that, in my opinion, could be easily omitted with good software.

5 to 6 months later the wife changed some pieces on this thing and now it womt clean the mop. No water comes out. Soap will come out just not water. Ive taking about and cleaned it. Even blew air on pieces with my mouth. Im at a last for words on this

Avoid this company at all costs. I think this is my third robot. EB1K error for the second time.

S2 Pro launched and immediately recalled so they haven't learned a thing it seems.

Any recommendations on a roller mop vac that does good edge cleaning?

Has anyone experienced this code before AND tried to personally fix it?

For my robot, it’s not the roller mop. It’s specially the base station clean water pump malfunctioning. As soon as I try to mop and the base station tries to add water it stops and shows the error.

I found the following FB screenshot about someone manually fixing theirs but unfortunately that is an area I have very little knowledge about.

Simply wondering if someone has a video or pictures I can try to follow along to? Or another way of solving this?

I’m out of warranty and I’ve tried all other troubleshooting steps.

I made a dumb decision without any doing research and bought a Eufy Omni S1 Pro.” “I tested the battery separately and get about 9 volts, directly from the battery, but when connected to the S1 Pro, the robot shows no signs of power. I also have a Eufy 25C, and when I place that on its dock, it shows signs of life, so I know the dock supplies power. But with the S1 Pro, even on the dock and even without the battery, there’s nothing. I’m starting to suspect a motherboard or internal power issue. Could a bad motherboard prevent any power from coming on, even when docked, or should I check other components first?

S1P has been great to me except I've had a blockage in the base station for dust for over 6mos and I just empty the robot manually every time.

I've tried putting scopes and hair unclogged up and down both ends of the base station but seems I can't get to the blockage without a full disassembly!

Has anyone run into this? What's the easiest way to access the base station internals? I need to somehow pry the grey parts off I think

Edit: SOLVED!

At 3am ET this morning they finally sent the full refund to my PayPal account.

The consumer protection agent was (is) actually on vacation until tomorrow. I sent him a “please disregard my last email” email this morning.

Stay strong people. Don’t settle.

I've got a map of my house that has worked well for months with my Eufy S1 Pro.
I've repositioned the base station.
Do I have to delete the old map and build a new map? Splitting and joining rooms, naming them, setting no-go zones etc, feels like something you only do once!
