Upgraded from s7 maxv ultra with the heater attachment and self plumbing / drain kit. I loved the s7 but i dread washing the filter and brushes because of the amount of gunk and the smell. I think i have very hard water so all of this congeals on the filter. The water tank above the mop also develops a bunch of black gunk as its very hard to wash the inside. Ive tried vinegar, alcohol, bleach, etc etc. You will see much less and limited models if youre in the US for direct drain and plumbing as it is not typically code to drain water here vs asia or europe. Anyway, i think only the x40 master from dreame or there is a saros one that comes with a complete plumbing kit. I chose the x40 master and although performance is on par, i see a few noticable improvements such as navigation, much quieter, flexible arms and mop for edge cleaning, and most importantly automatic hot water washing. No more stinky filters to clean and the entire pan can be easily removed and everything is accessible to clean. There is no more deattachable water tank on the x40. I think there is an internal one but it gets drained out and much smaller? I no longer smell dirty water when mopping also. I dont think i get much performance gains except for the edge cleaning . The rest are quality of life upgrades.

Agreed that its quite loud. Much better on the new one. The stinky mop i believe is derived from the water source and duration that it stays. Unfortunately not much i can do about that. I do have to say the obstacle avoidance is also much better. The s7 caught everything and got intangled everywhere. The x40 does a much better job. It got tangled once or twice but i blame my messy kids for leaving their mess everywhere...

Dreame X40 master and never have to refill water or dump dirty water ever again. Really minimizes maintenance compared to my previous Roborock S7 MaxV Ultra with add on mop dryer.

Dreame X40 master, no changing water and minimal maintenance. Exactly what these robots should be.

Dreame X40 master is on sale. After a more complicated install the maintenance is the least out of any robot. Currently on sale for $699.

The Dreame X40 Master is on the supported list, it's in the top 20 ranking on RobotWars and seems to support all modern robot vacuum features like vacuum/mop, auto empty station, vision and LIDAR navigation. If it were me, that's the one I'd pick.

Dreame X40 Master. I had the switchbot S10 and its light years better.

I bought the Dreame X40 Master for a specific reason. This is the version that you can fully plumb so that it will automatically fill and empty. I have mine hooked into my washing machine cold intake and it drains through the washing machine drain. A small pump on the unit can pump the waste water up to the height of the drain. It might function more efficiently if the drain were at ground level, but this setup works. I poured over reviews forever before deciding what to do. We ultimately went with the fully plumbed model because we also own one of those Tineco automops that look like a vacuum cleaner but it mops…and let me tell you if you don’t fully clean that thing out and leave any waster water behind…it stinks to high heaven the next day. The vacuum/mop unit we bought heat dries the mop pads after running to prevent smell, and we never have to worry about waste water sitting in a hopper. For vacuuming, we upgraded to their Tricut brush assembly, which handles long hair and pet hair very well. We run the vacuum at night after we go to bed. We cannot hear it from upstairs. Honestly I think it may be an exaggeration to use the term “life changing”, but frankly this thing can clean at I’d say 75% of the capability of a person with a vacuum and a mop. The MASSIVE advantage is that you can literally run the thing twice a day if you wanted, AND it gets into all the little nooks and crannies you might ignore if you were doing a quick clean every day. It spends roughly 3 hours vacuuming and then mopping, but you can set it to do both at the same time if you wanted. We liked the convenience of this thing so much that we bought a second machine for our second floor. Now our second floor is mostly carpet so we opted for the Roborock S8+, which has dual brush rollers and is extremely affordable. We don’t use the mopping function at all on this one. The dual rollers, according to my research, do better pulling things up from carpet. Let me tell you, I am shocked at how much crap this thing pulls out of our carpets even with running every day. The one caveat is that this thing requires a little bit of maintenance…I need to clean hair out of the rollers, which is really easy as it all bunches up at the end by design and it takes 10 seconds to peel off. Not sure if it’s because it simply collects more hair or if this is a design issue. I am aware that Dreame also has available the X50 master which may not be available in the US yet, at least it was not when I bought the X40. I believe this thing has more powerful suction and dual rollers.

Do you have the cash to buy the master series from Dreame? Base it’s more compact but you need to connect it to water and plumbing. Have you considered building a cabinet to hide the base? For a small home and a pretty clean one a mop exchange might work. But for a bigger home I would say it just smears the dirt from place a to the whole house. That’s why the base is needed. Even the rotary mops are not the best solution. I see the roller mop system better because it cleans the mop while washing the floors. Personally I would totally recommend a full base system even with water and plumbing connections. It gives you total freedom. Hide everything in a closet and leave it do its job.

Look into roller mop devices. Also do care about things that are dropped on the floor. I have the Dreame X40, cleaning is overall good but stains are a hit and miss. Candy or other sticky stuff is no go, like 0 chance of proper cleaning. You should be better with a roller mop because it cleans the mop constantly. Obstacle avoidance is critical for things like pens, crayons, toys. Here Dreame is good but not perfect. I had several pencils caught in the inlet. Family with 2 kids 8 and 4 + cat living in rural area. Additional advice, take the time to educate your kid, accidents happen but a jerky attitude sticks forever…

X40 hardcore owner here. Have it since February and have above 22k square meters cleaned (one shot vac and mop). My experience: more than decent obstacle avoidance. I am generally cautious about leaving cables on the floor. There were several situations in which the mop pads fell off due to cables getting tangled. The most dangerous is cables around walls and barely touching the floor. If a cable is dropped in the middle of the room it will be detected. Crayons and pens are its Archiles heel. Toys, if large enough, no problem. Lego is a no go. Clothes ok, socks - ok most of the times - I only had a incident. There is a function to clean around furniture legs - perfect cleaning of space allows it to go around. Things to keep in mod for Dreame - tech support and warranty tends to be shit, smart home integration non existent - not even decent integration with Google Assistant or Siri. Careful about carpets and ruggs - I don’t have any but people complain about Dreame in this regard. Watch some videos - non sponsored ones if you want the truth. Feel free to DM if I can further assist.

First of all what you see on Reddit is the opposite of positive reviews. Most people come here to complain or ask for help. So you’ll see mostly bad experiences. I have the x40 ultra from Dreame. Overall I am satisfied. Had 2 bad experiences and managed to solve by myself. 1. Squeaky sound at mop washing due to a previous issue where mop magnets caught some staples and scratched the base prongs. I’m now using Vaseline from time to time. 2. Poor performance while vacuum, brush wasn’t lowering enough. Somehow I made the robot calibrate. All good now. Obstacle avoidance is quite good but can be better. Especially with crayons and pens. Vacuum is ok, but could use a bit more power. 2 adults, 2 toddlers, 1 cat (oversheading all the time), 2 cleaning rounds of about 2 hrs for 60-65 square meters of actual cleaning in 2 rounds. I can welcome guests with white socks so I would say it does a good job overall. Dreame has good products, support and actual quality might be an issue. Imagine they 1st issue was a failed attempt with Dreame. Decided to solve by myself

Set it and forget it. 1x vac 1xmop&vac daily. And from time to time manual cleans. Daily water emptying and replenishing. 1 year Dreame x40

😂😂😂 you need a real robot, not a robot vacuum. Those chairs make it hard for a robot vacuum to pass. My suggestion is to seek for something that can first pass through that narrow space and then a robot that can be easily scheduled to do cleaning. Of course good navigation is a must. I’d first suggest new chairs or cleaning only when you can move the chairs. I have the Dreame X40 and I still move the chairs because it takes ages to clean around 6x4 legs+ table legs. Overall cleaning is good if sidebrush is used to pull dirt from nearby legs.

X40 owner. I have a cat that sheds like crazy. No hair on floors but I do find on couch bed and any other item that is not for the robot. I also have my wife and daughter with long hair. Except the ends of the brush I have no tangles, or close to 0. Or maybe when brush is worn out, har tends to pile up in the cut area. If you have a dog with long fur than having a proper brush is mandatory. Dreame has the tricut brush - seems to be less preferable for tiles due to noise.

X40 or P50 would be my choice. If budget is not enough L40 is ok

Battery is bigger on x40. I think that’s a nice to have. Battery degrades over time

Obstacle avoidance is a hit and miss. My x40 will sometimes get over cords, try to eat toys (lego most of the time). For sure it's better to have it than to miss it but there is no clear advantage in real world i think [Robot vacuum and mop comparison – Dreame](https://www.dreametech.com/pages/robot-vacuum-and-mop-comparison)

The new Dreame X50 autowash dock has had great praise, with people saying it effectively cleans itself and you will never have to maintain it outside of emptying the tray that catches larger debris. The x50 also can clear the thresholds supposedly. There is also the master version or even the ultra with the pipe hookups, then the only real maintenance will be the dust bag and the cleaning solution bottle. Then a weekly maybe even a monthly maintenance on it will likely suffice. I have a robovac that was released 3 years ago, and has voice commands, alongside scheduling, remote operation through the app, over the internet live video feed and control, voice calling through the robovac itself. Plenty of tools and features to help OP in their situation, and that is a much older model at this point

Mam Dreame X40 Master - mopowanie fajne działa - póki co po roku w robocie popsuł sie chyba silnik od miotełki albo pękł pasek. Muszę oddać na gwarancję. Samo sprzątanie spoko. Ciekawe jest to że robot potrafi odpiąc sobie mopy jak na dywan wjeżdza.
