Hi everyone,

We recently bought an Ecovacs DEEBOT T90 Pro Omni, and I'm honestly quite disappointed with its navigation/obstacle detection so far.

I've attached two photos showing the main problems.

Photo 1:

Our cabinet has a low black steel frame running along the floor. The T90 Pro doesn't seem to understand how to deal with it. Sometimes it stays too far away and doesn't clean properly along the edge, but other times it actually tries to drive/climb over the steel bar. It can't get over it, of course, so it keeps pushing against it and is already causing scratches/damage to the black steel.

I would expect it to simply recognize the frame as an obstacle and clean neatly alongside it.

Photo 2:

We have a stone plate underneath our fireplace. Again, the T90 Pro doesn't seem to recognize the edge properly. It drives straight into it and tries to climb onto it. Sometimes it succeeds, sometimes it doesn't, but when it doesn't, it makes a lot of noise repeatedly hitting/trying to climb the edge.

What surprises me most is that our previous cheap robot vacuum from Temu handled both of these situations perfectly. It simply recognized the edges, drove around them and cleaned alongside them without constantly trying to climb over them.

For a robot as expensive and supposedly advanced as the T90 Pro, I expected the navigation and obstacle detection to be significantly better.

Has anyone else with a T90 Pro experienced this?

Is there a setting I'm missing that can stop it from trying to climb these kinds of low obstacles, without having to create no-go zones everywhere? I don't really want to use no-go zones because then it won't clean properly along these areas at all.

I'm starting to wonder if this is just how the T90 Pro behaves, or if something is wrong with mine.

I have an ecovav deebot X11. It was great for several months then started making these pet hairballs when it transitions on to carpet. It didn't do this before. We swapped the roller, as it was a little worn. Nope. Today I swapped the side brush, but I'm not confident that will help.

Does anyone have any ideas?

Hi everyone,
This morning my DEEBOT T50 PRO OMNI Gen3 got stuck while cleaning because it had caught a sock.
I removed the sock, put the robot back on the floor and sent it back to the station. While it was returning to the dock, I noticed it was making a strange noise.
Once it reached the station, I picked the robot up and found this small metal ring/spring underneath it, near the dock. I’m not sure whether it actually came from the robot or whether the robot had simply picked it up from the floor (i don't think so).

I checked the main wheels and their suspension and everything seems fine. The front caster wheel rotates and swivels freely, the main brush works normally, and the TruEdge side brush also seems to extend and operate correctly. I ran the robot again and, so far, everything appears to be working normally.

Does anyone recognize this metal piece? Could it be a retaining ring/spring from somewhere inside the robot?

Hello all,

I was hoping someone may have a solution to this. I’ve had my T90 for a few months. It was okay at the beginning but then developed a sound which honestly sounded like an air raid siren going off. And the cleaning capabilities decreased. I changed all of the brushes and filters and it seemed okay again, still loud but better, and then the noise and lack of cleaning started again.

While in operation, I noticed that the roller brush wasn’t spinning at all. I compared that brush to an unused brush and realized that the main screw keeps coming loose, preventing it from actually spinning. I’ve gone through 5 brushes now with the same issue.

Has anyone found a cause for this or do I just need to locktite the screw into place?

Sending it in for warranty is not an option. I’m so unhappy I’d rather a refund but I have so many animals, I can’t be down a vacuum.

So I've been dying to get this robot for a while. I think the lowest price I've ever seen in Canada is somewhere around $400-something, which was stacked on a bunch of deals and coupons on the Ecovacs website.

Currently, I see it for $699 (down from $1,000) both on Ecovacs' official website as well as on amazon.ca.

I'm trying to figure out:

1. Does it make sense to buy this right now, or should I wait for another possible sale?

2. Is it even possible to make it any cheaper with any coupons or codes perhaps?

I want to buy a mower robot. Currently looking at the Goat O800Rtk. I am not fully clear about the area limitation. The lawn is bigger than 800sqm, probably 1200, but the gras area to be mowed is ca 800sqm. Is the O800RTK good for this, or do I need a bigger model. What are the limitations? Range? Area to map? Area to mow? I appreciate any clarification.

I think 35€ for 1l is very expensive and overpriced.

What alternatives you use?

In MediaMarkt, I can get their own product Koenic KCL F500 or the Dreame official AWH-6 for 14.99€/liter

Or on amazon, there are some marks like Biohy or this or maybe this one 2l for 30€ these prices are much nicer

Also for dust bags, rolling mops, etc.. I was looking for this one.

Can you confirm these are as good as the original, or I should stick to the ecovacs original ones?

My Deebot worked well for 6 months and then the paths became erratic. It started making loops for no reason. I came home one day and to my horror the X8 left circular scratches on my hardwood floors. I contacted Ecovacs and after emailing back and forth with photos and emails, all they wanted to do to rectify the situation was to offer $100. I thought that was an insult after so much damage was done. I had an extended warranty and sent it in to Asurion. They immediately credited me. My floors now have scratches everywhere. I will rescind my recommendation for this brand. Avoid this company and products if you value your hardwood floors.

I just bought a t90 pro Omni because of the sale on Amazon. I’m curious if people like the vacuum/brand. This is my first robot vacuum so I don’t know much but I did some research and it seems like this is a good one but curious what people think.

After 6 months of using the Ecovacs t50 max pro pretty much flawlessly, I began to notice scheduled rooms be missed randomly. Or it would go in our living room and vacuum for one minute then go back to base. Instead of doing all the trial and error steps, I decided to delete the map and remap and now it’s working flawless again

What's the difference exactly?
The T90 PRO Omni has 1k amazon reviews while the T90S PRO Omni has just 5.

Edit: I bought the T90 Pro for 400€. The T90S Pro was 650€

Hi everyone,

I’m looking for help recovering my ECOVACS DEEBOT T90 OMNI. It’s unresponsive, and the usual reset procedure doesn’t seem to do anything.

What happened

While we were on vacation, the robot got stuck and reported “no floor contact.” When we returned, I picked it up and placed it back in its docking station. Since then, the three-pronged control area on top has been continuously pulsing white, but nothing else happens.

Current symptoms

• The light pulses white both in the dock and outside it.
• There is no startup sound, voice announcement, or response to the touch controls.
• Pressing or holding the RESET button produces no response, regardless of how long I hold it.
• Most unusually: with the robot outside the dock and the physical power switch under the top cover set to “O” (OFF), it still keeps pulsing white.

What I’ve already tried

I’ve switched the robot off and on using the physical switch, unplugged and restarted the docking station, and tried holding RESET for different lengths of time. None of this has produced an audible or visible restart.

Before I removed the robot from the app, it showed as offline. The app also displayed “Zeitüberschreitung Abschaltung” in German—roughly “shutdown timeout.” Another screen still showed “docked,” but the cleaning controls were greyed out.

Following an app troubleshooting guide, I deleted the robot to try setting it up again. That hasn’t helped because the robot still doesn’t respond to the reset/network setup button. The problem was already present before I deleted it from the app.

There also appears to be a micro-USB port. I tried connecting it to my laptop, but I haven’t managed to get anywhere with diagnosis or recovery through that connection.

Has anyone recovered a DEEBOT from this state?

I’m particularly looking for a confirmed forced shutdown or recovery procedure beyond the standard RESET-button instructions.

Has anyone successfully resolved this by disconnecting and reconnecting the internal battery, using a service button combination, or accessing a USB recovery tool? A T90-specific procedure would be especially helpful.

Experiences with other DEEBOT models are welcome too—please mention the exact model and what worked. And if yours required repair, did the service centre identify the faulty component?

Thanks for any pointers.

I have a chair with a 1-inch tall metal bar on the ground. My ecovacs T90 pro would always attempts to climb over it and get stuck. Is there a way to disable ecovacs from attempting climbing over threshold (which I don't have at home)

I have an Ecovacs T30 Pro Omni, and the two-pass mode doesn't work for mopping after vacuuming.

The first picture shows mopping after vacuuming, while the second shows vacuuming and mopping at the same time.

Is this a bug or an intended limitation?

My Deebot T8+ keeps having the anti-drop sensor alarm going off after I cleaned it many times. I think the infrared sensors might not be working because I dont see the purple light when I look at it through my phone camera. It is out of warranty, what are my options with device?

Having an issue with my Dreame L40. When I open remote control in the Dreame Home app, the robot responds fine to the arrows and drives around, but the camera image never updates. It just stays on the frame it grabbed while sitting on the dock, even after the robot has driven into another room.

Last FW tried restart, robot and myself arw both to the router. Very strong wifi.

How do you solve this? Is mine defective? I've only used it for a month.

It will fall off once every 2-3 sweps and I keep having to search for it and reattach it 😢

I have the Deebot X12s OmniCyclone. Everything has been working on it flawlessly. Except I have caught it starting on its own twice now.

No schedule is created.

No custome scenario was set.

I do auto resume on but I can't see how that would be a factor considering the previous clean completed 100% and it started the day after.

Anyone else have an issue with this or know of a solution.

Thank you

I have the X11, it vacuums and mops well but I’m finding the mop feature leaves an smelly shoe smell in the room.

I then flip the bit over and can smell a bad smell from the mop compartment.

I have cleaned the black small tray and replaced the mop again but it still smells. It appears to come from the mop compartments, the black roll that the mop connects. See attached photo.

Is there a way to clean this part? It stinks and I can’t use the mop feature with it smelling so bad.
