Intro
The X40 Ultra is a self-emptying, hybrid cleaning robot that combines strong suction with an automated mopping system and on-board maintenance features. It targets households that want a more autonomous floor-care routine—especially homes with mixed floor types (hard floors plus area rugs) and pet hair challenges.
If you want a machine that not only vacuums but also lifts and cleans its mop pad on the dock, the X40 Ultra is worth a close look. Quick verdict: a technically ambitious robo-cleaner that prioritizes carpet protection and low-touch maintenance, with a few caveats around connectivity and unspecified physical dimensions.
Keywords: X40 Ultra (primary), robot vacuum (secondary), robot mop (secondary).
What’s in the Box
- Not specified by the listing.
- Inferred (typical items included): robot vacuum-mop unit, charging/docking station with maintenance module, main brush and side brush, removable mop pad(s), water/reservoir tanks, power cable, quick start guide — Not specified (inferred items may vary).
Design & Build
The listing doesn’t give material or exact size/weight measurements, so the build description focuses on observable design choices and their implications rather than specific dimensions.
- Construction and materials: Not specified. Most models in this class use ABS/plastic housings and rubberized wheels; expect similar materials unless manufacturer states otherwise.
- Form factor: The X40 Ultra is designed to operate under low furniture and in tight corners—features like a liftable/extendable side brush and RoboSwing mop motion indicate a low-profile cleaning intent.
- Ergonomics and serviceability: Key service interactions are handled at the dock (mop washing and drying) and via removable parts (a removable mop and likely detachable dustbin). Because the dock performs hot-water cleaning, daily maintenance on the robot itself should be minimal.
- Practical implications: Without listed height/weight specs, measure door clearance and under-furniture gaps at home before buying if you have very low-clearance furniture.
Key Features
SideReach Liftable & Extendable Side Brush — Better corner and edge cleaning
The X40 Ultra uses a liftable, extendable side brush designed to reach into wall corners and around table and sofa legs. In practice this helps sweep debris away from edges into the robot’s suction path, improving pickup along baseboards and in tight spaces where a central brush can’t reach. Expect cleaner corners without repeated passes.
Real-world benefit: homes with skirting boards, dining chairs, or sofa legs will see fewer missed crumbs and pet hair near edges.
Removable & Auto-Lift Mop — Protects carpets from wetting
This robot can physically remove its mop or auto-lift the mop assembly up to 10.5 mm (0.41 inches) to avoid wetting carpets and rugs. That lift height is intended to let the robot pass over low rugs without dragging water onto them. You can also define no-mop zones in the app so the robot avoids rugs entirely.
Why it matters: If you have area rugs that don’t tolerate moisture, this feature reduces the risk of accidental wetting and staining by the mopping system (source: listing, checked 2025).
12,000Pa Suction — Strong pickup for hair and debris
The unit claims an industry-leading 12,000Pa suction power, paired with an optimized air duct to maintain airflow. That level of suction is aimed at more reliably gathering pet hair, larger debris, and embedded dirt on hard floors and low-pile carpets.
Where it helps: homes with shedding pets or lots of tracked-in dirt will notice fewer missed bits, and the optimized duct reduces clogs during longer runs (source: listing, checked 2025).
OmniDirt Detection & MopExtend RoboSwing — Smarter spot treatment
OmniDirt detection helps the robot sense stubborn, concentrated dirt patches and respond with increased attention. MopExtend RoboSwing gives the mop a scrubbing motion that can reach under low furniture and into corners more effectively than a passive pad.
Real-life scenario: spilled spots in the kitchen or grime tracked under sofas get more aggressive localized scrubbing rather than a single slow pass.
Auto Maintenance with Hot-Water Cleaning — Low-touch mop care
The base station washes both the mop and washboard with water heated to 158°F (about 70°C) and offers four temperature settings in the app. This aims to reduce stains and odors in the mop assembly and extend the hygiene interval between manual cleaning.
How this helps day-to-day: you won’t need to hand-wash the mop as often, and the hot-water cycle can help reduce buildup from greasy kitchen spills and pet odors (source: listing, checked 2025).
Note: the robot supports only 2.4 GHz Wi‑Fi for app connectivity (source: listing, checked 2025).
3D Structured Light, Camera & LED Navigation — Precise mapping and indoor maneuvering
Navigation combines 3D structured light with an onboard camera and LED illumination to map and move around a home accurately at all hours. This setup supports room learning, custom modes, and creation of pet zones or no-mop zones through the companion app.
Practical benefit: more predictable routes, fewer surprises around fragile objects, and easier setup of restricted areas for pets, carpets, or delicate rugs.
6,400mAh Battery & Auto-Resume — Longer runs and seamless completion
A large 6,400mAh battery is intended to provide extended runtime so the robot can finish larger areas without interrupting. If the battery gets low, it returns to the dock to recharge and will resume cleaning where it left off.
Benefit: less manual intervention for multi-room or larger apartments (source: listing, checked 2025).
Performance & Use
Setup tips
- Wi‑Fi: Only 2.4 GHz networks are supported. If you use a dual-band router, ensure the robot is connected to the 2.4 GHz SSID during setup (source: listing, checked 2025).
- Placement: Install the dock against a wall on a flat surface with at least a small clearance each side; keep the charging area free of clutter so the robot can find and dock reliably.
- Mapping: Let the robot perform a full mapping run before enabling advanced features (pet zones, no-mop areas). This yields more precise zone edits later.
Daily use and modes
- Vacuum-first strategy: If you have a lot of dry debris, run a vacuum pass before heavy mopping. The X40 Ultra’s suction helps pick up loose dirt so the mop scrubs only the soiled residue.
- App controls: Use the app to adjust mop temperature (4 levels) and define virtual no-mop or no-go zones. The lift function and in-app zone settings combine to protect rugs from moisture.
Mop maintenance
- The dock’s hot-water cleaning reduces manual work, but inspect the mop pad and water tank periodically for wear and debris. Replace mop pads per manufacturer recommendations or when visibly worn.
- Empty and refill tanks as instructed; water reservoirs collect rinse water and may require occasional cleaning to prevent odors.
Troubleshooting pointers
- If the robot struggles with docking or navigation, check camera lens and LED for smudges and wipe clean.
- For suction loss, remove and check the main brush and air duct path for entangled hair or blockages.
- Keep firmware and app updated for navigation improvements and feature tuning.
Energy and scheduling
- Auto-recharge and resume allows larger cleanup jobs to complete over multiple sessions. The listing mentions optimizing charging during off-peak hours to save energy costs—use your router or home automation schedule to shift dock charging if your utility supports it (source: listing, checked 2025).

some guy –
This robot works great — both the vacuum and mopping functions are solid. It climbs small thresholds easily (up to about an inch), automatically empties itself, and is ready to go again. The Dreame app is intuitive: you can remote-control the vacuum with live camera view, send it to specific rooms or custom zones, or run a full clean. Mapping is accurate, suction is strong, and maintenance is straightforward. We have cats who occasionally vomit, so I don’t schedule fully automatic runs without first checking for any messes (otherwise it can spread the vomit around). For others this isn’t an issue — there’s a scheduling feature in the app. Pro tip: to remove hair wrapped around the beater brush, pull out the whole bar, pop off the small end plugs, and the hair rings come off easily.

I’ve had this device for a week. We bought it because our house is large — three floors — and we’re two older adults; the person who used to help with cleaning stopped coming. Setup was very easy: just read the manual and follow the steps. After that we tried it and were pleasantly surprised. I can say with certainty the floors have never been this clean in a week. I programmed it to clean the ground floor three times a week, and twice a week I carry it up to clean the upper floor. We’re very satisfied with the results. I’m thinking of buying another one for the upper floor so I don’t have to move the robot up and down. I also want to study its modes more to make better use of it. We’ll keep testing during the trial period, but for now we are completely satisfied.

I’m really impressed with this robot vacuum. Its clean white finish looks sophisticated and fits my home perfectly. After the first run the whole house felt completely clean — it picked up dust and pet hair and tackled corners effortlessly. The navigation is smart and precise, avoiding obstacles and reaching under furniture without issue. I appreciate that it automatically returns to the base for charging and mop cleaning, making upkeep nearly effortless. Strong suction, effective mopping, and overall performance that exceeded my expectations. Quiet, powerful, and convenient — highly recommended.

I’d always hesitated to buy a robot vacuum, but I found a deal on the X40 Ultra and it was totally worth it. It cleans better than my wife and I do—no joke! Setup was simple; I just refill the clean-water tank and empty the dirty one. We have a Border Collie and it’s excellent at picking up all the hair. Highly recommended — I don’t know why I waited so long. Great investment that saves a ton of time.

I use this in a high-end garage with tile floors that I clean weekly. I blow debris out first with a leaf blower, then put the vacuum/mop to work. Problems I’ve had:
1) The dust bin does not self-clean and fills quickly. I empty and clean it after every run. I assumed it would self-empty, but it does not — so most users will need to empty it each time. For comparison, my indoor vacuum/mop from another brand (used for two cats’ hair) picks up more debris than the X40, so I don’t think the garage floor is unusually dirty.
2) The mop pads fail to install automatically every single time. I schedule it to vacuum then mop, and it always errors when it tries to attach the mops. I have to install them manually, and there’s no “resume” function — I must reprogram it to mop-only. This adds a lot of hassle.
All told, it takes 5–10 minutes to get the X40 ready to clean, and when it stalls installing the mops I’ve spent up to 90 minutes manually fixing it. I expected multiple unattended cleaning cycles — that’s not the case. Because of these issues I originally rated it 2 stars.
The floor ends up mostly clean, but a manual mop does a better job even on the wettest, deepest setting, which is disappointing. If I could do it over, I’d try a different high-end brand or just buy a cheaper unit since the mopping performance is poor. I would not buy this again.
EDIT: Changing my rating to 1 star. The app stopped working — it opens to a blank screen and I can’t fix it. There’s no pending app update, and Dreamhome’s servers may be down (they’ve been down for 4+ hours). I’ll try reinstalling the app, but for a $1,200+ vacuum I shouldn’t have to troubleshoot this.

Es una compra excelente: aspira y trapea muy bien, se nota la diferencia después de la limpieza. No es necesario limpiarla constantemente, pero sí recomendable hacer limpiezas a fondo de vez en cuando para evitar que se acumule polvo y deje de funcionar bien. Sin duda la volvería a comprar.

I use the X40 on my main level — about 800 sq ft of tile and 600 sq ft of carpet — and I’m judging it purely on cleaning performance. Honestly, my floors have never been this clean. It’s brought me back to using robot vacuums full-time.
I’ve run the X40 over the whole main level at least 20 times. Previous robots would get stuck on cords, towels, socks, and almost anything on the floor. The X40 has only gotten stuck once. I had collision avoidance turned off (it makes the robot more sensitive to obstacles but keeps it further from walls); I’m confident that with collision avoidance on it likely wouldn’t have gotten stuck at all. The point is: I don’t have to run around clearing every little thing off the floor anymore. I can start it, leave the house, and come back to clean floors — a genuine game changer.
Remote control via the phone app works great if I forget to start it before leaving. For my mix of floors I set the mop wetness to almost maximum and have it wash the mops every 10 minutes (it really washes them — it doesn’t just spread dirty water). With these settings it finishes cleaning without me refilling or emptying anything.
Crucially, my carpets never get wet. The X40 can drop the mops at the base station before cleaning carpet, a feature that sold me on it — previous robots sometimes left thicker rugs damp even when they “lifted” the mops. The “clean genius” mode works well, and I’ve created Shortcuts so each room can use specific settings (e.g., repeated intensive cleaning for a messy kitchen).
Maintenance is far less of a hassle than with earlier robots. The X40 returns to the base at a customizable frequency and automatically empties the vacuum bin, discharges dirty water, refills the clean water, and actually washes the mop pads — all without my intervention. It even cleans the base station. My regular chores are minimal: tap the filter to clear fine dust (or wash and dry it), empty and rinse the dirty water tank, refill the clean water tank, and pop them back in. The whole routine takes under 10 minutes, and I only do the full routine every three or four cleanings.
Serviceability is excellent: the brush roller is easy to maintain — end caps come off and hair or string can be pulled off the axle. Much easier than my old robot. The software is extremely customizable, though not always intuitive: settings and language can be confusing and some options are hard to find. That said, the customization more than makes up for the occasional UI frustration.
I love having consistently clean floors and appreciate how independent the robot is, how little time it requires from me, the extensive customizability, remote control, the locator beep, and the onboard camera that shows where things are. I liked it enough to buy the similar but cheaper X30 for downstairs and another X30 for my college daughter. She loves it — and so do her cats. Unlike her old robot, the X30/X40 map rooms and clean in predictable back-and-forth rows, which the cats tolerate. If a pet stands in front of the robot it will avoid them.
Bottom line: lots of praise and very few complaints. Out of the box, “clean genius” did an excellent job, and unless you’re a tinkerer the automatic settings are more than adequate. Also, customer support has been very responsive. I didn’t realize how much I’d come to depend on and enjoy this robot until I started writing this review.

It doesn’t handle old stains well, but overall it does a great job. Worth the price. I’d give it 4.5 stars, but since that’s not an option I give it 4 stars because for now it’s the best of its kind.
