"This model will be best for homes with heavy shedders as it will compress the fur in the dustbin as it vacuums to best utilize the space."
"the same models can also compress the fur in the dustbin as it vacuums. ... the models with the fur compression feature will be able to push any fur to the end of the dustbin and will not be as easily clogged with empty spaces."
"The dual anti-tangle main brushes work great for pet hair and the same models can also compress the fur in the dustbin as it vacuums. ... I have a heavily shedding corgi and the old robot wouldn’t be able to handle his fur as it’ll be clogged with a lot of empty space on the sides of the dustbin to the point that running it twice a day would mean he wouldn’t shed enough for this to happen. ... However, the models with the fur compression feature will be able to push any fur to the end of the dustbin and will not be as easily clogged with empty spaces."

"The dreame L40S Pro Ultra has much better obstacle avoidance and object detection for smarter cleaning features like stain detection and large particle detection where it’ll slowly mop only or slowly vacuum only and not use the side brush so it won’t be kicked away."
"My LDS-only Xiaomi would always get tricked by a floor to ceiling mirror and think there’s a magical place beyond it due to the limitations of LDS. ... My Dreame L40S Pro Ultra (same 110° LDS sensor but with an RGB camera and fill light) was able to accurately tell that the mirror was actually a mirror wall and after cleaning that room, correctly identify it as a wall (the LDS and the RGB camera would fight while it’s cleaning the room over whether or not it’s a wall or a magical portal but it wised up when it finished cleaning that room)."
"For some reason your tool ranks it near the top for basically every category even though it has significantly worse object avoidance than than the Dreame x40 and L40 ... The best feature of the L40/X40/p10 pro ultra is that they have class leading object avoidance so you don't have to pick up your cat's toys or prep your house every time you want to run the robot meaning you can run it on a daily schedule which will keep your house cleaner. ... I run my X40s daily and they never get stuck on cables, cat toys and other random junk that ends up on the floor."

"The AceClean dryboard (its mop pad cleaning tray) on these models is currently the best self cleaning mop tray that can clean its mops as the only maintenance required is to occasionally clean a removable palm-sized drainage filter and wipe down the flat dryboard (no nooks and crannies for dirt to hide)."
"the new dreame robots (L40S ultra, L40S pro Ultra, and the X50 Ultra) in Australia cleans its own filter when it autoempties."

"I find that with daily vacuuming first to remove any debris that could scratch the floor, then making it mop (using the vacuum first before mopping setting so the spinning mops won't drag any debris which will scratch your floors), made my wood floor have a nice sheen and noticeably felt softer, and the tiles were always barefoot friendly."
"way better mopping ... With kids + sand? Go Dreame and don’t look back."

1999_peugeot_406 1.0I also got the l40 ultra AE, but in op’s situation, the L40s ultra is a much better option
2222014 1.0Just bought a Dreame L40S Ultra and a L40s Ultra AE, one for each floor of my house. So far they blow every roomba product ive had completely out of the water, However I like the AE more. The Regular Ultra (Non AE) is very finicky, its tried to eat every cord in my entire upstairs more than once and finds cords I didn't even know I had, its consider louder than the AE and the fact that it leaves its mop pads at the base is unreliable it sometimes "forgets" one or both then just throws a tantrum and shuts down, and it refusesto go under chairs or small tables that should be fairly navigable. The AE is a tank, it seems to have far superior navigation and object recognition, and the mopping is much more reliable. I did tons of research on Vacuum wars website and YouTube page and caught them on Black Friday at less than half price each.

Been a huge fan of our dreame l40s ultra AE so far, 5 dogs, 1 kid, hard wood and carpet, it does it all.
I got it on sale for $549 on black Friday with a coupon, for that price it was impossible to beat.
Yeah I ordered it from Amazon in the US
Acacia_Sky 1.0It is awesome!! ours arrived earlier than expected and has exceeded all my expectations!
We got the Dreame L40s Ultra Pro - the Australian version - and it rocks! I can say I walked into my living space this morning to fresh, clean, streak free floors! and at a much cheaper price than we originally thought we were going to have to spend :-D In Australia it is still 1k, but i think it's earning it's keep already and the app is really good too.
ALLEyezOnMe_XO 1.0Yeah, my observations are identical. We recently started looking at robot vacuums, after we returned our Eufy X10 Pro Omni, and it seemed as if every single model has issues, yes, plural :D We ended up getting the Dreame L40s Pro Ultra and albeit it's doing a pretty good job, it suffers from the issue where it randomly drops its mop pads and I have to re-attach them manually. We worked around this by having the robot not leave them at the station while vacuuming. Oh well.
I had the X10 Pro Omni and it was great, but it’s software went downhill after a certain version and the robot became pretty much unusable. I ended up swapping it for a Dreame L40s Pro Ultra and never looked back. Granted, the Dreame was €200 more, but it’s money well spent.
Our L40s Pro Ultra suffers from the "mop pads random detachment issue". Otherwise, it's a pretty solid choice. Do your research before getting it, though, as you may have to deal with returns / replacements. Contrary to what most people are saying, dealing with Dreame's support has been great - fast and adequate responses.
Yup, I feel you. L40s Pro Ultra is a great value for money and the mop pads issue is the only one I’ve encountered so far.

If you don’t care about possible returns / exchanges, go for it. I just find it super annoying to have to send back both the robot and the station, even if only one of them is problematic, but oh well…
We got a Dreame L40s Pro Ultra for 749 EUR and it's been awesome. I was also looking at the Mova V50 (Pro / Ultra / Whatever), but it was about 200 EUR more, so I decided against it. Roborock Saros 10r also seems to get good reviews, but it too is on the more expensive side. P.S. We used to have the Eufy X10 Pro Omni, but their firmware turned out to be complete garbage and we returned it for a full refund.
If you are willing to spend, get the Mova V50 Pro Ultra Complete. If not - the Dreame L40s Pro Ultra (brilliant value for money, got ours for about €750).
amandainpdx 1.0Get the L40. I explain why here [https://www.reddit.com/r/RobotVacuums/comments/1lr2zgt](https://www.reddit.com/r/RobotVacuums/comments/1lr2zgt)
# [Under $300](https://amzn.to/48R0G4J) Generally speaking, I think its rare you find a great robot at this price, and I've discussed why there's some sense in [not spending the money on real discount robots](https://www.whatrobotvacuumshouldiget.com/2025/06/20/are-budget-robot-vacuums-worth-buying/). Still... there are a few gems worth looking at, as more expensive models drop under this threshold. If you've got a smaller place, or a place with many floor objects, try a Switchbot. Because they're so small, they can get between chair legs and make a small radius around things. Switchbot just doesn't get enough attention, IMO. Lots of people purchased the K10+ Pro on my recommendation during Prime Day and have posted about how happy they are. The 11 made the tower smaller and improved some other specs, but is mostly the same model. The perfect apartment, studio, or office vac. Performs spectacularly well as a vacuum, particularly given the price and stats, but it is ONLY a vacuum. If you're more concerned about a mop, get the 3i. (its great at both, to be clear, but it has the best mop of the bunch). I really like the 3i brand, they're not new, they've been making robots for other companies for years. The G10 is stripped down from premium models, but it had the same sweeper>roller design that is so effective on the higher end models. If you're looking for a carpet forward model, Eureka is the only legacy vacuum brand that successfully transitioned to robots that work. While no brand has great customer service anymore, there's a benefit to Eureka being US based. No waiting 24 hours for a response. |**Model**|**Original Price**|**BDD Price**|**Discount**| |:-|:-|:-|:-| |[SwitchBot Robot Vacuum K11+](https://amzn.to/4mOxq1O)|399.99|224.99|44%| |[3i G10+](https://amzn.to/48znS7N)|$449.99|$269.99|40%| |[Eureka E20 Plus](https://amzn.to/4mOwQBd)|449.99|299.99|33%| # [Under $500](https://amzn.to/4o4MPMA) Were seeing some amazing deals in this price band. That L40 Ultra has dropped from the original price of $1499 to under $500. So many people have been grabbing this model since Prime Day and most of them report being quite happy. While it wouldn't have been my favorite at a higher price, at this price, you're getting a premium model at an absurd sale price. I absolutely love the 3i current line up. The vacuum and mop are both fantastic and the app-easy. This is basically my top pick (3i S10 Ultra) minus the dehumidifier. The P10 still has the great sweep/roller design and gets up debris no other brand can without getting clogged. Get this one if you're concerned about larger debris. The Eureka is better than it should be. I loved the sweeper design, it moved debris off hard floors and carpet very effectively and would be my pick for carpet. Rarely got stuck on anything or reported errors, and it was just really reliable. I recommended this model during Prime Day, and got a lot of good feedback from folks who picked it up. |**Model**|**Original Price**|**BDD Price**|**Discount**| |:-|:-|:-|:-| |[Dreame L40 Ultra](https://amzn.to/48Rswhk)|$799.99|$469.99|41% | |[Eureka J15 Ultra](https://amzn.to/4gUYACY)|699.99|489.99|30%| |[3i P10 Ultra](https://amzn.to/4h1Sy3y)|$1,099.99|$469.99|55%| # [Under $750](https://amzn.to/4nypaUV) Roborock has won my loyalty over the past few years by producing consistently reliable robots, and the S5A is no different. A variant of the Qrevo line, with spinning mop heads that extend. While Roborock may produce an absurd number of models, and the S5A is no exception, they are reliable for an exceptional app experience, with intuitive setting locations, great support and good hardware with easy to find replacement parts. The L40S is the best of both worlds. A premium vac, at a not premium price for now. This is the model with the best balance on this list, of vacuum and mop. It improves over the L40 in the previous band with better nav and suction. Finally, if you want to emphasize mopping, Narwal does it really well. My two issues w this model are that it uses a ridiculous amount of water and there's a giant button on top of the machine your pet or kid will want to bop. If you don't mind refilling a lot, and you dig into the settings to lock the button (or don't have kids/pets) this is ideal. |**Model**|**Original Price**|**BDD Price**|**Discount**| |:-|:-|:-|:-| |[Narwal Freo Z Ultra (White Version)](https://amzn.to/46IEhUI)|$1,499.99|$550.00|63%| |[Roborock Qrevo Edge S5A](https://amzn.to/46ZYXI5)|$999.99|$649.99|35%| |[Dreame L40s Ultra](https://amzn.to/4o5ARCv)|$1,099.99|$749.99|32%| # [Under $900 ](https://amzn.to/4oad9oS) From the day it was released, I thought the Curv was a steal, most of the premium features of the S8 line, at a better price with improvements to the sweeps, extending out beyond the robot. The CurvX improves on the Curv with higher Pa and better nav. I do think its a better vacuum than mop. The X9 is a better mop than vacuum. but other than getting clogged here and there, was generally a good vacuum, and this is a reasonable price for it. Eureka is the best surprise this year. The J15 line is consistent and reliably performing. I love the sweeps, its a very effective mop and carpet cleaner and offers US based support. |**Model**|**Original Price**|**BDD Price**|**Discount**| |:-|:-|:-|:-| |[Ecovacs x9 Pro Omni](https://amzn.to/46CySzK)|$1,599.00|$899.00|44%| |[Eureka J15 Max Ultra](https://amzn.to/46UkK3x)|1199.99|$899.00|25%| |[Roborock Qrevo CurvX](https://amzn.to/48PvS4j)|$1,499.99|$899.99|40%| # [Over $900 ](https://amzn.to/48OKBMY) In this band are my top two recommendations. Let's start with my favorite robot of all time (a BIG statement). 3i has been making robots for other brands for a while, but the 3i is their first flagship. The S10 Ultra blew me away and became the only robot I've ever kept after testing. It will vacuum anything, without getting stuck or clogged. I mean, giant pieces of mulch. No problem. It cleans water on its own and generates more from the air, so it truly is set it and forget it. Totally autonomous. I've been yapping about it for months, and of everyone who bought it during Prime Day, I'd say people were split, 60/40. Most loved it, but some complained of a musty smell, which makes sense, since the unit is basically a dehumidifier (that's how it generates water). I've had mine for 6 months and don't notice a smell in a very wet state (Oregon), but it seems like something worth noting. So let's talk about the Flow. I tested the Dreame and Narwal roller mops, (and previously, the Eufy roller mops). Everyone is obsessed with roller mops, but the Flow is the first one I recommend. The flow improves on the Freo Z and X by not needing to be refilled constantly, and the vacuum improves over all other Narwal models. I still don't think roller mops are the end all/be all, so I wouldn't recommend dropping $1500 of this model, but I do think the Flow is worth buying at this sale price. |**Model**|**Original Price**|**BDD Price**|**Discount**| |:-|:-|:-|:-| |[3i S10 Ultra](https://amzn.to/4o7hKIe)|$1,899.99|$1,099.99|42%| |[Narwal Flow](https://amzn.to/3IxMoLX)|$1,499.99|$1,099.99|27%| If you're looking for ALL the models on sale for Big Deal Days, they're [here](https://www.reddit.com/r/RobotVacuums/comments/1nvsulx/every_robovac_on_sale_for_amazon_big_deal_days/) or s[ee all sales models at once](https://amzn.to/4nt1sJH). For some context, I [write about robovacs](https://www.reddit.com/r/RobotVacuums/comments/1l48fms/i_write_about_robot_vacuums_for_a_living_ama/) both for an online pub and my own site, and we get access to prices beforehand, so long as we don't share them before brands ask us (embargo). I shared similar information and advice for [Prime Day](https://www.reddit.com/r/RobotVacuums/comments/1ljl8wd/prime_day_deals/), and people were generally pretty [happy](https://www.reddit.com/r/RobotVacuums/comments/1m0sjou/amanda_amanda_amanda_the_dreame_l40_is_amazing/) w the recommendations from the feedback. Feel free to ask questions. I'll also produce a list of recommendations per price band in another thread. I'm not sure these are ALL the deals out there, but these are what's been released to me (that's off embargo). These are affiliate links, I had mod permission (I assume, still).
I prefer the other two models in that price band, but the L40 is still a great machine and its a fantastic price.
barabba_dc 1.0Yes the L40S or even called L40 PRO in some regions has additional features compared to the L40 ultra. And yes dreame's product marketing team gotta be high all the time 🤣
bart_grewup 1.0Thanks for the update! And the explanation on the L40S Ultra. After I realized it had bad obstacle avoidance I returned it on Amazon without opening it. Still waiting on the reviews for the Aqua 10, Z60 and Flow. On the one star reviews, I notice a lot of the Amazon reviews are bundled together for different robots. For instance the MOVA Z60 reviews are mostly MOVA V50 reviews. How is that handled?
Benzoat_ 1.0Yes their is a different between the Ultra and the Pro Ultra, as far as I can tell the Pro Ultra has a better sensor suit. The L40s Ultra only has Lidar the L40s Pro Ultra has Lidar and a Kamera. I dont know why Dreame sells the Pro Ultra not in Amerika and only the rest of the world.

BigPirateBits 1.0Hey mate. I’m in Australia too and doing the same research. My shortlist for this price range is eufy x10 pro Omni at Harvey Norman for $999 or Dreame l10s pro ultra heat $1199 at Amazon. I’m currently determining if it’s worth stepping up to mova p50 pro ultra ($1750) or Dreame L40s pro ultra ($1799) as I have two messy young children and full size single story house for it to look after.
I think I have landed on the Dreame L40s pro ultra on sale at JB currently. Seems to have all the features. If you are dead set on cutting roller the mova seems a goer.
bobybumbie 1.0I have ADHD and cleaning is not one of my passion. I also live by myself so if I don't clean, no one will. Usually I'd clean every weekend or at least I try to lol which means no vacuuming/mopping during the week or over a week. I have 2 cats so their shedded fur, little pieces of litter and the food crumbs were always on the floor. they'll accumulate again after a day so I kinda closed one eye (or both 😂) and ignored them.... so y'all can understand why I really wanted one Coming to a messy home is frustrating and having messy living space doesn't help with my psyche. It was just so difficult to make a decision as every big brands have x variations of the same "model" and they all seem to have similar features.... and most of the official websites don't really offer customer friendly comparison tool. so honestly I didn't know what to buy. After weeks of watching review/test videos on YT, lurking on this subreddit & Vacuum Wars. I decided to get mid-range robot vacuum while there is end of financial year sale (I'm in Australia) and the only way to get over analysis paralysis is to compare directly. My initial budget was around $1200AUD so I shortlisted vacs around that price range and also included ones up to $1500ish if it was highly recommended by the reviewers (that didn't have "paid promotions"). Once I listed all the key features and specs, I highlighted the ones that stands out (top 2-3) and according to this analysis Dreame was the winner. I pondered buying L30 but really liked the extending side brush. I put it to the test as soon as I set it up, and it vacuumed and mopped almost perfectly! The floor hasn't been mopped over 3 weeks so there were some parts that were still not clean after initial vacuum&mop cycle so I ran it again for areas that still needed more rub. The floor is a section of the living room where I had the most foot traffic so I ran 2 cycles.. I really cannot complain how well it did. One thing I didn't realise was that it only has the extending brush on the right side and there's none on the left and it still vacuumed just fine. I've set up 2 daily cycles: vacuum only in the morning and vacuum+mop in the afternoon so the house would always be clean when I come home after work or when I finish wfh. I haven't tried cleaning on the carpet as I'll need to pick things up from the bedroom floor, I'll post an update when I run them in the bedrooms tomorrow or this weekend. I'm so happy that I finally bought one and it's doing a great job!
