X40 Ultra Series

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 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.

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.

I didn’t like the e28. I have been living with it for a couple weeks now and it’s going back. And also that’s why I feel it’s not worth buying a flagship robot vac at these prices rn. The tech is progressing very quickly and in just a couple years, current tech will be old news and a lot of these performance issues will be much better. I ended up buying a refurbished Dreame x40 ultra [on eBay direct from Dreame for $399](https://ebay.us/m/eFO7eZ). I mean even that vacuum released at $1900 just a year ago.. not worth these high prices for new robots with questionable performance.

Check out the Roborock q5 max+ Now this is a bit over budget, but Dreame has a refurbished store on eBay and was selling the x40 ultra refurbished for $399 last week. Just bought one the other day. Looks like they’re out of stock but I wouldn’t be surprised if they get more in if you keep an eye out. They also have the [l40 ultra for $449](https://ebay.us/m/UROL86) rn. You will not beat that value and performance at that price. Just wanted to point it out in case you have some wiggle room as you get better vacuuming, self refill and emptying mopping, plus cleans its own mop pads.

Well said. I’ve tried a few of the pricier ones and just bought a Dreame l40 ultra as my “budget” option to compare. While I think the pricier ones are a bit better in performance (in some ways, not all) it just feels silly spending $800+ on a machine whose features will be dated in just a couple years. I mean just take the Dreame x40 ultra for example. Last year they sold new at $1900. Now you can get one for around $500. And You cannot beat the value of the l40 ultra or Mova p10 pro ultra. I think it’s the perfect robot for most peoples needs.

Hey how is yours working? I ordered the exact same one and maybe mine is a dud but it keeps going in circles with no rhyme or reason. It’s also registering carpets when there are no carpets there.

The x40 that I bought was refurbished and had wonky navigation so I sent it back, but bought a new l40 ultra and I really like it. The navigation is pretty good and object avoidance has been pretty solid too. Is it perfect? No. And the T80 is probably still a bit better at mopping. But it was good enough for me to realize that it wasn’t worth paying the extra money for the T80 or e28. So both of them got sent back and I kept the l40 ultra. As for the Mova v50, I have it sitting in its box still in my house as I decided I’m going to send it back for the fact that I don’t feel it’s worth me spending twice the price as the l40 ultra for what is likely marginal performance gains. Don’t get me wrong I am sure it is better, but I’ve come to the conclusion that the robot vac tech is just moving so quickly that spending money on a premium robot whose features will be dated in just a couple years wasn’t a good idea. So I’m happy with the performance of the l40 ultra and will be keeping that one.

Dreame was selling refurbished x40’s on eBay for $399 the other day. Such a killer deal I had to snag one.

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 already have Dreame X40ultra , but the issue with these robo vacuums with mob functionality is that their cleaner liquid is very expensive. I am still searching for cheaper alternative. Its working great though its still dumb and repeated mapping done still it gets stuck in 1 or 2 places. When it vacuums the floormat its sound is high which can get a annoying. P.S. be ready for expensive cleaning liquid supplies if you choose mob functionality version.

I find a lot of good information on YouTube and also I've had robots since they came out in the beginning cuz I was into rescuing dogs! I had three different robotic Vacuums at the same time two of them were mop combos dreamy x40 and the narwal freo z.. I liked both really well but I thought that the Narwhal was a bit better at mopping and the dreamy was better at vacuuming and also had a better battery life but since I had a robot that also vacuumed I stuck with the Z. I get a lot of information from people that have them and I also get a lot of help because people try a bunch that I haven't tried and I get to find out real world experience with them. Just like I got an e25 you fee and I'm telling people how I really think about it. I really think that they are coming a long way fast! The other difficult thing is that everybody's got a different type of house or apartment and so what works really well in one house may not work well in another.

Some of us really like narwal.. I took it over the dreamy x40 Ultra cuz I had both of them at the same time and the quality seems to be better on my Z has more features it's going to be a tough decision between the flow and the dreame version of the roller mop

Hence my comment about my roomba i8+... and vacuums much faster and much better than all of the newer models with a single anti tangle roller! I've never had any problems with my Roomba having tangles maybe the early ones in the early 2000s so pretty much what happens is I vacuum with it all over the house and then mop with the other one because I can't mop and vacuum my entire house with the same machine at this time.. the dreamy x 40 was the only one that could actually vacuum and mop almost my whole house.. but I was terribly paranoid about the extending arm because people were saying it was breaking on them?!

I want the new dreamy cuz I liked the battery life of my x40 my Z is okay but I can't vacuum and mop whole house.. and right now my Roomba has decided to come out on its own and vacuum for me?! LOL

I still have I8+ roomba and still use it to vacuum as most robots these days are kinda slow because of having to think so hard lol.. most won't clean to the edges sufficiently dreame x40 did cuz of arm but didn't like spin brushes leaving a gap when mopping...narwal z had for 8 mos no real problems but again vacuuming seems better with 2 rollers like roomba's..but does decently enough when mopping and vacuuming..all of them get stuck sometimes 🤔 but freo z does have great obstacle avoidance but uses a bunch of water.. e25 liked but mop didn't extend and vacuum was meh.. have 3i s10 now but it does get stuck in a few places ..doesn't like some carpets but does have water recycling and drawing it from the humidity in air..super cool! also have checked water quality and it is great! for mopping..doesn't leave weird mottleing on my white tile.. but have been hearing people having to return them cuz things go wrong with them?. I also use this one in mop and vacuum mode after roomba goes 1st cuz that seems to help it go closer to cabinets.. I clearly have an issue cuz I want to keep them all! They need better battery life, and faster processing to finish jobs..seems more innovation more problems so depends on your particular house but don't give up the roomba just yet lol I've had mine since it came out!! And it keeps going even with same battery it came with but I take care of it / them maintenance wise..

Agreed had x40 dreame that was nice and I really did like 3i s10 some except quite a few ppl had problems with smell from inside ?

Dreame X40 certified refurb https://www.ebay.com/itm/356944631986 Cleans like a flagship, has good battery life and great obstacle avoidance. Missing some of the features like threshold climbing that the newer robots have, but still a solid performer for $320

It's alright. Battery life is way worse than my old x40. I don't really use many of its features such as the retracting lidar and threshold climbing. The only feature that I like that my x40 didn't have is the self cleaning filter which reduces the service intervals. If you are looking to buy a robot, I would just buy the certified refurb x40 which is like $320 right now: https://www.ebay.com/itm/356944631986 It was the flagship back in 2024 and it's missing the fancy features such as threshold climbing and retractable lidar, but it cleans really well and the obstacle avoidance is great. The certified refurb comes with an extended warranty as well.

X40 is a great performer. You can get a certified refurb model for $320 right now from Dreame's eBay store. Comes with a 2 year extended warranty. https://www.ebay.com/itm/357118449793

Sticking with my X40 until more roller style robots come out. I want roller style mopping, exceptional obstacle avoidance, and exceptional vacuum performance. My x40 is overall great but the vacuum performance leaves a bit of debris on hard floors that my old wyze robot vacuum has no issues with it.

My old L40 and X40 rarely ate cords.

Get the certified refurb Dreame x40 on eBay while it's still on sale for $319-$400. You will be getting flagship performance with exceptional obstacle avoidance at a low to midrange cost and a free extended warranty

What's your price range? There are the fancy flagships with all their features like threshold climbing, roller mops, multiple mop pads, retracting lidar and made up pressure numbers. I've got a Mova v50 and z60, happy with both of them but had two certified refurbished Dreame X40 ultras before. The x40s were basically flawless even though they were certified refurbs and ran daily on a schedule for over a year and a half before the front wheel broke and sent both in for warranty repairs through the extended warranty that you get with certified refurbs. Both were deemed unrepairable and I got a check for $1000 per robot. I bought my x40s for $800 through eBay. Even with the issues I had, I still recommend the x40, the L40 and the Mova P10 pro ultra 1st gen (identical to the l40, mova is a sister company of Dreame). These bots have flagship level cleaning performance and obstacle avoidance but are just missing the over the top bells and whistles that frankly cause more issues such as battery drain. Right now the certified refurb x40 is on sale through eBay for $319 which is an insanely good price considering it's a 1 year old flagship that performs better than any robot you can get even up.to the $500 price range. https://www.ebay.com/itm/357118449793

Skip the roller mop for now. The tech needs more time to mature. I have a z60 and I'm not very impressed with it, wish I got a Dreame x60 or just another Mova V50. Spinning mop robots work as well after an initial deep cleaning and are significantly more reliable and have less maintenance while being thinner so the can fit under more furniture. Right now the best value for money is probably the Dreame x40 ($319) and L40 ($299) certified refurb from their eBay store. I had two x40s before getting my z60 and v50 and loved them. At $319 with a free extended warranty the x40 is a no brainer.

Get the L40 ultra certified refurb from Dreames eBay store. It's practically identical to the x40 in cleaning performance only differing in it's battery size. It's on sale right now for $252. You could buy two of them and have one for downstairs and one upstairs if you really wanted to. Pair it with the tricut brush and you won't have to worry about hair tangles. https://www.ebay.com/itm/356930402616 I had an x40 for two years before upgrading to a Mova v50. The x40 was excellent and the v50 isnt really better other than being quieter when on max suction and just quieter overall. I have three cats and my x40 did a great job picking up their hair and avoiding eating their cat toys. Don't put much emphasis into the pascal ratings. They are all bullshit and don't really tell you how well the robots clean. Cleaning performance is a function of alot more variables than just pascals and the way each manufacturer tests isn't comparable. Save your money, get the L40, it will be perfectly fine for your use case. If you really need special features like retracting lidar for better clearance and threshold climbing, check out the Mova V50, it is much better than the L40 gen 2, heck even the old L40 is better than the gen 2 since it has an actual obstacle avoidance system.

Do not get the z60 if you have a floor plan that's larger than 500 sqft. I had one for the past 5 months and it was nothing but issues. 1) navigation is horrible: The Z60 would constantly confuse itself and think carpets are thresholds and try to climb them and fail to consistently clean. It would also get stuck in loops where it cleans the same area multiple times. The navigation with the lidar turret up is basically drunk and when it's down for cleaning low clearance areas its like it took acid, inventing all sorts of areas on the map that don't exist. Yes, I cleaned the sensors and reset the robot and remapped multiple times. Mova also confirmed the camera and lidar was working fine. 2) The mop requires lots of maintenance The design of the mop and it's water jets requires lots of maintenance to keep clean and not clog up. If it does clog, the robot leaves puddles of water everywhere. Even with regular, weekly maintenance, the mop would leave puddles of water everywhere 3) Horrible battery life. The robot could barely clean 500sqft without having to go back and charge for a few hours. Something is wrong with the "x50" generation of robots that Dreame and Mova, all of them (x50, l50, v50, z60) have horrible battery life and idle power draw. 4) Super loud vacuum motor. The vacuum motor or the suction path makes the robot hit a really unpleasant resonance frequency that makes it super loud when it's cleaning when on turbo or max suction. It's very disruptive and unpleasant to be around. After all the issues I had I opened up a support ticket with Mova and thoroughly documented my problems. They agreed that a new robot would not fix the issues that I was having and agreed to refund me for the full purchase price of the robot after months of owning it. I sent my robot back in the original packaging and they refunded me promptly. Overall, excellent customer service and accountability from mova which is why I will recommend their other robots, just not the z60. We also own a Mova v50, which performs much better but still has the battery life issue. Honestly a bit of a downgrade from my previous Dreame X40 and the Mova P10 pro ultra gen 1. We also own a Roborock Saros 20, and while it's obstacle avoidance isn't as good as the z60, the navigation is significantly better and it's battery life is significantly better being able to clean our entire floorplan on one charge even with carpet cleaning on max suction. Skip the Z60 and other roller mop designs for a few years, wait for the tech to mature and then buy one. Spinning mop pad technology is very mature and is good enough for most homes as long as you run the robot regularly.

Yeah the Saros 20 is replacing the z60. The roborock is alot more systematic and reliable at navigating my floorplan. I have a sunken living room and I have a ramp that goes down to my living room. My Saros 20 used the map on its first mapping run without issue and reliably uses it without getting stuck. My Mova would constantly lose its position after entering the sunken living room. My old Dreame x40 was also able to use the ramp and navigated decently, but not nearly as well as the Saros. I've generally stuck with Dreame and Mova due to their superior obstacle avoidance but their latest generation of products have take a step back in navigation efficiency and battery life. Roborock also stepped up with the saros 20 and finally fixed their historically horrible obstacle avoidance.
