Updated to five stars on April 8, 2025.Ecovacs sent me another unit and this one is amazing. It seems the units I had to return may have been a part of a bad batch. The new unit has triggered zero error messages for the past few weeks, cleans and mops amazingly well after quickly scanning and mapping my rather large house in less than 30 min.The AI is responsive and well implemented.The best part, and the ultimate reason I stuck with Ecovacs, is the level of support I received, and the commitment to resolve my issues, which is super rare these days.A bit of constructive feedback on the Ecovacs app:- The cleaning log currently only reports each session as "Rooms Cleaning", along with duration of sq footage of each job. It would be substantially more useful if the log included which room(s) were cleaned in each job and what type of cleaning was done (i.e. Vac, Vac and Mop or Mop after Vac).- The bugs I reported in my original review are still yet to be fixed.Overall, I am impressed with the X8 Pro Omni and would highly recommended.Original review:I really wanted the Ecovacs Deebot X8 Pro Omni to work. Unfortunately, it turned out to be a disappointment and I would not recommend it.I saw the Deebot X8 Pro Omni at CES in January and bought it as soon as it became available on Amazon in February. Out of the box, the unpacking and setup experience was seamless and I was very impressed. The bot very quickly scanned and mapped my rather large house with little corrections. The app is pretty intuitive and I very quickly figured it out.The problems started on Day 2 of using the Deebot. It started throwing a "Bumper Stuck" error for no reason. It would do that 8 or 9 times per run regardless of whether it was vacuuming or mopping. Each time the bot was not actually stuck under furniture in any way, just sitting there waiting to be reset. To get it to continue, I would need to bump the bumper as instructed in the app, and then push the button on the bot to continue. For a modern top-of-the-line Ai-enabled bot that is supposed to vacuum and clean the house without intervention, this was a terrible experience. It is virtually impossible to leave this machine to finish the job on its own without having to bump it and reset it every few minutes.In fairness, Ecovacs email support was pretty responsive. I contacted them and they asked me to reset the bot to factory settings, then start over. That didn't help, unfortunately, as the bot kept throwing the same "Bumper Stuck" error every few minutes after reset.At some point, a piece of plastic fell out of the machine. I sent a picture to Ecovacs support and they determined that the broken piece could be causing the "Bumper Stuck" problem. Ecovacs offered to send me a replacement unit, but would not specify timeline and I decided to return it to Amazon instead as it was faster and more convenient.I immediately purchased another Deebot X8 Pro Omni as I thought the first one was just bad luck getting a defective unit. On Day 2 of running the new unit, the same exact issue started happening. "Bumper Stuck" error every few minutes without the bot actually being stuck in any way.I contacted support again and they offered to send me another replacement, without committing to a timeline again.I decided I'd had enough of unpacking, packing and repacking Deebots, so I returned it through Amazon again and have since purchased a different brand, which should be delivered in the next few days.I do like Ecovacs as a brand, but it seems they may have released the X8 Pro Omni a bit prematurely. The product needs a lot more testing to deliver to expectations. In addition to the issues described above, I discovered a few more bugs while going through the process of troubleshooting.- The app has a couple of areas that reach a dead-end blank screen, forcing you to completely kill and restart the app to get out.- When the station's dirty water tank is full, instead of showing a message to empty it, the app throws a "Robot dirty water box error" with instructions to pull the box from the bot and "clean it". Well, the dirty water box on the bot is full simply because the station's dirty water tank is full, not because it has malfunctioned, and you need to find that out by trial and error.Bottom line, not ready for prime time. I'd wait for this product to mature a bit before purchasing.
