Reliable, great mopping (lifts pads), but poor cable avoidance.

I had an x40 ultra that got warranty refunded. I’m in my first week with my L50 ultra and I’m cautiously optimistic. After a few days fiddling with settings it is operating how I would like it and doing a decent job of it. It does have the hardware for matter but is not “yet” supported. The only negative I have so far is that it’s battery life is atrocious.
I’m about a month in with my L50 Ultra. I’m in a 750 SF NYC apartment with wood floors, tile and 3 low pile area rugs, 2 sheddy dogs and a sheddy (beautiful) wife. After reading this post I just flipped my bot over for the first time to check the brush. ZERO tangling. It does fantastic on the hardwood/tile and I would say it’s very very respectable for the carpet. I upgraded after an X40 Ultra had a fatal error and am much happier with this unit than the X40 Edit: the “hair compaction” feature in the base station also seems to be quite effective.

I live in a one bedroom NYC apartment with wood, tile and low pile carpet. I have 2 dogs who shed constantly and a beautiful wife who also sheds constantly. I previously had an X 40 ultra. It was constantly getting tangled, even with the tri cut brush. Plus, after a few months it really just wasn’t picking up debris. Even though I serviced the filters, base station etc. So far with the L50 I haven’t had any of those issues. The only real complaint I have is the battery life and its navigation/map took a few weeks to really dial in with my apartment.
I can not recommend dreame/mova (same company) our x40 ultra went back to them because it did not do the job, I was on tech support for over a week with zero answers. I can not speak about the newer models, they are not on any of my lists. Roborock is at the top, their mapping is top notch and feature set as well. Narwal flow but i dont think the onboard bin is going to handle 2 German shedders even with a daily schedule. Ecovacs has a good rep and so does eufy. we will see what happens on the 20th and 28th. if I bought early I would want to know if they have a price guarantee in place just in case. dont want to over spend on something that wont last 3-5 years ie. app, battery ,parts
Roborock saros 10r top of our list Eufy E25 2nd this is already at BF pricing according to eufy Dreame/mova same company and had x40 returned it Narwal not seeing the fantastic reviews from individuals and the onboard bin might be too small for 2000sqft home with 2 shepherds even with daily vac JMHO
Hated dog hair the bin is small and it had no option to go back any faster to the base to empty so it would just push piles of hair around till the algorithm told it to go back and empty but it would never retouch the pile it left. they kept telling me to select a function that was not in my menu. so they took it back took months but its gone. and service is 1 email a day after they answer the phone on first ring so one problem will take a week to sort out and they dont want to call you back, just email there comes in around 2 am yours goes back at around 9am and then wait
If you have the gift card, I dont have one but dont want the e25, Im looking at the mova z60, I just dont want the experience we had with the dreame x40 pushing dog hair around and never really picking it up. we have the bot run everyday a little over half the house twice a week and the main are daily with 2 german shedders well you get it
Sounds like its the one, my x40 never got an update to make it empty more often
I have the X40 Ultra and really enjoy it.
My home is a mix of hard floors and rugs. Last week, on a whim, I got the Shark PowerDetect 2in1 (vac and mop) from Amazon for £477. I was impressed with the cleaning power of it but had to send it back because I was unable to get it to clean under my sofa or up to the kickboards in my kitchen. I would have kept it if it wasn’t for that. Today I got a Dreame X40 Ultra Complete for £699 as I did my research this time and have found it to be a lot better suited to me and totally covered what was missing from the Shark.
I got my first robot vac last week, a Shark 2in1, and found that the app/controls were lacking (I couldn’t get it to clean under my cupboard doors up to the kickboards or under my sofa) so I called Shark and they told me to send it back for a refund. I did some more research and got a Dreame X40 Ultra Complete that I am very happy with.
Valetudo just got support for a couple of eureka robots, the J15 for example looks really decent. Otherwise the Dreame X40 Ultra Heat also supports Valetudo.
Yea, I‘ve heard about the versions mess of dreame. That’s one of the reasons that there will be no further support for future dreame robots. Unfortunately I don’t have any trustworthy tests of the X40. It is just the newest dreame model that supports valetudo. There is also the mova p10 pro ultra, which seems to be decent. But this one is basically not available on Germany
It is just a possibility if you get a step wrong or are to slow. It is not complicated, but the last step of rooting the robots needs to be completed within a time limit. So it needs to be done carefully and well prepared. I know, that’s a big disadvantage of the Eureka robot. That’s why the X40 would be still my favorite
I’d prioritize a robot with antitangle rollers, decent mopping (usually starting at the 500 USD range), and an easy to clean robot. Really good midrange option: dreame l40 ultra or the MOVA p10 pro ultra at about 500. They’ll deliver the best bang for buck performance. The x40 ultra should also be in this price range. It should come with an antitangle TriCut brush that works but generally makes it louder. The most expensive options have quieter antitangle rollers as they don’t cut the tangled hair but direct it to the dustbin with their tapered end. A bit more expensive but better mopping: the eufy e25 at 629 USD has antitangle brush rollers that work and a decent roller mop. do ask Eufy’s customer support for their updates dirty water component as the one the first gen ones ship with have a leaking issue. I don’t see any other robot in this price range that mops better. Most expensive with the best mopping that doesn’t really come at the cost of vacuuming pet fur at 999: the MOVA Z60 Ultra SA has antitangle rollers and a good roller mop that can extend to clean closer to edges with antitangle combs on the roller mop to prevent tangling. It’s very similar to the MOVA Z60 Ultra Roller which is more expensive with the only difference being threshold crossing wheels but the mopping is the same. MOVA sent me their Z60 ultra roller to review as part of their Reddit collaboration program and I found it to mop really well with no tangles anywhere other than fur wrapped around the fluffing roller which you need to clean once every 30 working hours (the app reminds you).
I only talk about this feature because I was able to verify that it works. My older robot with the same dustbin design as the X40 ultra would have clogged in the middle with empty space on the sides of the dustbin. https://preview.redd.it/jyapw2wybnmf1.png?width=2847&format=png&auto=webp&s=2c8cbad9819430e8fbe0831d232fef2be4b6c947
This is what my old robot’s dustbin would be like. It had the same design as the X40 Ultra. https://preview.redd.it/stxg6wfgcnmf1.png?width=1599&format=png&auto=webp&s=ce3e14aacfadbdcce58a1c100b3ba63c28e4c3dd
You mentioned that you have the x40. This model is prone to clogging with fur. The new dreame/MOVA models with fur compression do much better with fur and autoemptying. I tested the high frequency autoemptying setting and it autoempties once every 12sqm≈130sqft which is going to be more than enough. As for customer service, this is something many brands have to improve on.
The main difference is that the X40 has an RGB camera for obstacle avoidance but the others don’t as they only have structured light. This will matter if you need it to avoid things like cords and U-shaped furniture legs.
Otherwise they’ll all clean about just as well. I prefer the roborock edge and Curv to be easier to clean as the mop washboard is removable unlike the dreame X40.
Dreame GoVac 508 should be a rebranded Dreame X40.
The x40 is alright at its current discounted price, you just have to remember to tap the dust out of the small filter once every few cleaning runs. It is not as well suited for heavy shedders due to the small dustbin at 300mL and it can clog with fur in the middle but have empty space in the sides. I would recommend the newer x50 or the MOVA v50 for the larger dustbin (395mL) and has a fur compression feature which I found to actually work so it can maximize the space in the dustbin. The main downside is that the battery efficiency isn’t as good as the X40. https://preview.redd.it/yp4h53f1rpcg1.jpeg?width=3024&format=pjpg&auto=webp&s=0cbcd17d32f08e83a3f064da8c7b72f28c2fc0bd As for buying (in the US), buy it from eBay from the official store with the Allstate extended warranty as it will mean Allstate will just refund you if your robot broke and if customer service is less than stellar.
