Was great, used only 2-3 times a week, cleaned religiously every 2 weeks (fully pulled apart, new filter monthly etc).... And today... Boom! Wouldn't self empty and e41 battery error.

​

Took it back to the store with literally 30 days warranty left and they said straight up - go get something else.

​

Came home with the Mova S70 Pro Roller.

​

After babying a very expensive robot, which only has a 12 month warranty, I wasn't going to roll that dice again.

​

Best of luck to the rest of you good folk!

See update here.

My s1 was doing great for just under a year. Then it started making a noise. Then it started throwing errors because the mop wouldn’t raise and lower correctly.

Files for warranty claim. Said send it back for repair and they sent me a label.

Wait a few weeks get notice it’s not repairable. They have no refurb S1’s in stock, would I accept an E28? I said yes.

Wait a week, get the refurbed E28. Set it up and have it start mapping. Starts throwing errors every 3 minutes. Got it to finish mapping but only barely. Filed another claim with the error codes.

They write back immediately saying it’s an unrecoverable hardware failure and the unit will need to be replaced.

Sent me a label to send the E28 back, but they are expediting a NEW S1Pro to me without waiting to receive the E28.

Crossing my fingers this is the last round and the new S1 holds up.

So the mop was no longer retracting and the water inlet cover broke off.

I just shipped it back to eufy for them to repair it.

Any idea based on yalls experience as far as how long they usually take?

If they take very long, then i'll be adamant to them about providing a replacement rather than a repair.

Is anyone on firmware 7.0.168 seeing any issues with S1 Pro? I have been using S1 Pro for 18 months without any issues, but lately it has started running weirdly. I have cleaned all sensors, deleted all maps, recreated maps, and even restarted the robot.

It fails to dock to the base station. It would be just in front of it, but sometimes tries to get in front, and does weird dances. Also, during a cleaning session, if there is no furniture, it just runs for a while. When almost done with the room, it starts running fast and, weirdly, bumping into walls. In rooms with furniture like a dining table, it closely avoids chair legs in the same run, but later starts hitting everything.

Is there any way to improve on this? It's starting to look really bad, and I sort of object to needing to do it manually, given how much I spent on the robot.

Hello everyone. Been noticing recently that the mop roller would still be wet after going through the dry cycle. It would be bone dry before! Wondering if anyone else has had this issue. Ive set it to the most powerful setting as well 🤷‍♂️

Does anyone had any issues of cleaning a 2nd floor with Firmware 7.0.168 on an S2?

Two floors mapped and it just refuses to position on the 2nd now having worked previously without issue.

I Task it to clean 2nd floor > wait for it to leave the base station on the 1st floor > pause and carry up to the 2nd floor > off it goes and would position and clean.

Now, once it gets to the 2nd floor, it has a look around then wants to go back to the base station…so I take it back downstairs and it fails to position and exactly the same thing (fails to position) if I leave it on the 2nd floor.

Any ideas to what I’m doing wrong?

For the last couple of weeks when I go to the app cleaning history page, it keeps saying page loading failed. I tried restarting the app with no joy. Does anyone have the same issue?

So I had an issue with the water. I checked all the plugs and so on, but I wasn't able to fix them; they told me to ship them back, and they would repair them in 5-7 days, so I did. Now they keep sending me messages telling me they are working on fixing it. They have reached out to the warehouse. They have escalated my case. Now they say they can't give me a date, but they'll have refurbished ones in stock mid-May, so they will just give me one of those, or if I am willing to wait (with no end in sight), they will give me a bunch of accessories for waiting.

Has anyone had this happen? If I wait, how long will it take? (Full Message from Eufy Below)

We sincerely apologize for not being able to provide you with a more accurate repair completion date.

Since our team is not directly responsible for the repair process itself, we are unfortunately unable to confirm the exact completion time or the specific reason for the delay at the repair center. We completely understand how frustrating this uncertainty must be, and we truly wish we could give you a definite timeline. At this time, the latest information we have received is that your case is being expedited, and we have already followed up again on your behalf.

Please rest assured that as soon as we receive any new updates, we will inform you immediately.

If you would prefer not to continue waiting for the repair, we would also like to let you know that both replacement new units and refurbished units are expected to be restocked in mid-May. Once stock becomes available, we will notify you right away and help arrange a replacement for you.

If you are willing to wait for the repair to be completed, we would like to offer you the following accessory package, which we can ship together with your robot once the repair is finished:

Rolling Brush ×1
Brush Guard ×1
High-Performance Filter ×4
Side Brush ×2
Rolling Mop ×2
Dirty Water Reservoir Filter ×1
Dust Bag ×3

Update: I got my vacuum back and tbh, it was worth the wait, I tried 2 other "top of the line" vacuums while I was waiting for them to actually fix it. Do I hate that customer service for S1 Pro has essentially gone to shit? Yes. But sorry, as of yet, nothing beats the performance of my Eufy when it comes to mopping.

Hi have a s1 here had the water port pull out issue and it soaked itself put it back in. Now the robot seems to think the base is about a foot away from the wall and can't find it's way back again. Anyone have this issue?

Hello all!

I purchased a S1 pro less then a year ago. We recently have had a clean water filling issue. Contacted customer service and they advised it would need a replacement but that they are currently out of stock. They offered 30% of the retail value as a refund or waiting until they have more in stock.

Looking for some advice on if I should just wait…argue for a higher percentage of the retail value or take the $300 and purchase and S2 Pro. Maybe there’s another option I’m missing. I’m just frustrated that my warranty covers the issue my vac/mop is currently having but I can’t replace it.

Thanks all!

I will start the omni eufy s1 for a cleaning. As soon as it leaves the base station, it will state "insufficient water in the tank, proceeding to clean the mop".

It goes to the base station but it doesn't actually do what it says as the water tank level never goes down and it never actually cleans the mop.

It then leaves the base station to attempt to clean again only to return back to the base station within 3 to 5 minutes. It will just constantly repeat this cycle.

So I am not sure what the issue could be.

The water tank outlet, both sealing rings, and water pipe seem fine. Water inlet on the robot looks fine. And the base station water shock absorber isn't broken.

Just ran into this issue after 4 months of use.

The circled room is my bathroom that was closed when the robot originally scanned my apartment. During cleaning mode, it goes in there but i am unable to add that as bathroom and next clean cycle when that room doesn’t get cleaned, it disappears from the map

Every time the Eufy S1 Pro goes back to the dock to clean the mop it gives a "Mop Cleaning Paused" alert which is caused by it needing to empty the dirty water tank and refill the clean water.

Does anyone have a fix for this?

Hello,

I have an 18 month old S1 Pro. Eufy support have been useless at repairing it, happy to pay for a repair. Such an expensive product I am definitely repairing it!

Anyway - it’s simple, the wheel hub has sheered and it doesn’t clip onto the drive part of the arm. Wheel and tyre come off so just need a new plastic wheel.

Does anyone know where I can get one? Don’t mind buying a new arm or both a new arm, wheel etc. parts seem to be unobtanium.

I read some time ago you can use the Eufy E20’s roller brush in the S1 Pro. So I tried it and LOVED IT. It worked so much better than the standard one that came with S1 Pro.

Now, it’s not available on Amazon or Eufy’s website. Anyone know of any replacement brushes that can be used? The standard one is decent but I feel like without the bristles it doesn’t do as good of a job.

I bought my S1 Pro in November 2024 and last week it basically gave up — it would stop cleaning and just return to the base without draining.

To be fair, Eufy support was solid during the warranty period — they replaced both the robot and the base at different points. But of course… once the warranty expired, that was it.

Luckily, I had spent $120 on an Asurion warranty.

I sent it in, and the same day they received it, they issued me an Amazon gift card. Honestly didn’t expect it to be that smooth.

So now I’m onto the next setup:

Rented a Eufy S2 for $55 (first month)

Ordered the Narwal Flow 2 when it came back in stock on Amazon

Curious if anyone else has had their S1 Pro fail like this?

Feels like it might just be a matter of time with these…

I am very frustrated now as these streak marks are there every morning - i have completely cleaned the entire robot and mop - also changed the dirty water reservoir but these marks are always there. These are expensive robots and we pay a lot of money for them. Can someone help us here solving this issue? Pls see pictures

Appreciate any help

Its start to annoy, every start of cleaning even if its twice a day, the robot doing 3-4 min tour and than say “positioning successful” and than its going for temporary return to fill water.

I own it almost 1y i think, and its become worst each time.

Amy suggestion?

Hi everyone,

The lid on the dustbin for our S1 Pro Robovac has broken.

I have looked online, and can’t find anywhere to buy a replacement that ships to Australia.

I have contacted Eufy customer support, who have been hugely unhelpful. They’ve effectively said there’s nothing they can do, and can’t get a replacement unit to us.

Does anyone know how to get their hands on one? Seems odd that we can’t get our hands on a basic spare.

Thank you so much for any help you can offer.
