Dreame X40 Ultra Review 2025: Smart Cleaning Powerhouse
The Dreame X40 Ultra is not just another robot vacuum. It’s a full home-cleaning assistant that vacuums, mops, and even cleans itself. In 2025, this machine stands out for its power, automation, and convenience.
I spent several weeks reading through user experiences, expert reviews, and product updates to create this complete review. By the end, you’ll know exactly what the X40 Ultra does, how well it performs, what problems it can cause, and who should actually buy it.
1. What the Dreame X40 Ultra Does
The Dreame X40 Ultra is a robot vacuum and mop combo. You don’t need to push it or guide it. You set it up once, and it moves around your home, cleaning floors on its own. It vacuums carpets, scrubs hard floors, and then returns to its dock to empty its own dustbin, wash its mop pads, refill water, and charge itself.
That’s right — it handles almost everything automatically. You only need to replace the dust bag or water occasionally. The goal of the X40 Ultra is to give you clean floors every day without you lifting a finger.
The “Ultra” in its name means it includes the most advanced dock system Dreame makes. The dock is huge because it holds tanks for clean and dirty water, a bag for dust, and the mechanism for washing and drying the mop pads.
2. Design and Build
The Dreame X40 Ultra looks premium the moment you unbox it. The robot itself has a round design with a raised LiDAR tower on top that helps it scan the room. It comes in sleek shades of white or dark grey, depending on your region.
The dock looks like a small washing machine. It’s taller and deeper than docks from cheaper robots, but that’s because it does a lot more. The front of the dock has a door for the dust bag and compartments for clean and dirty water tanks. The top has a screen and touch buttons for manual control.
The robot uses high-quality materials. The wheels feel sturdy, the brushes attach easily, and the mop pads fit securely. The overall design gives a feeling of long-term durability.
However, it needs space. The dock measures around half a meter in width and height. If you live in a small apartment, finding the right spot for it can be tricky. It also needs access to power and enough room around it so the robot can dock properly.
3. Key Features
Here’s what makes the X40 Ultra special:
- Very strong suction – Dreame says the X40 Ultra delivers up to 12,000 Pascals of suction power. That’s among the highest in robot vacuums today. This strength lets it pull dirt from carpets and cracks more effectively.
- Liftable mop system – The mop pads lift automatically when the robot moves onto carpets. This feature stops the robot from wetting your rugs.
- Mop Extend function – The mop pad extends slightly to reach closer to walls and corners, giving cleaner edges.
- Automatic dock maintenance – The dock empties the dustbin, washes and dries the mop pads, and refills clean water. You can go for days or even weeks without touching it.
- Large battery – The 6,400 mAh battery lets the robot clean large homes (up to about 300 square meters) on a single charge.
- Smart navigation – The robot combines laser scanning (LiDAR) and cameras to build a map of your home. It can identify furniture, detect obstacles, and avoid small items like shoes or cords.
- App control – You can control everything through the Dreame app. The app lets you create room maps, set cleaning schedules, choose areas for vacuuming or mopping, and adjust water and suction levels.
- Voice assistant compatibility – It works with Google Assistant and Alexa, so you can tell it to start or stop cleaning by voice.
4. Cleaning Performance
On Hard Floors
The X40 Ultra performs superbly on hard floors like tile, wood, or laminate. Its strong suction picks up fine dust, crumbs, and pet hair in a single pass. The side brush sweeps dirt from edges into the main roller, and the mop scrubs away footprints or sticky spills.
Because the mop pad rotates and applies steady pressure, it removes dried stains better than many older models. The extended mop pad also cleans along baseboards more thoroughly than standard mops.
On Carpets
On carpets, the X40 Ultra automatically increases suction power. It lifts its mop pad to stay dry and focuses on vacuuming. It collects dust, hair, and debris efficiently. It handles low- and medium-pile carpets with ease, but very thick, plush carpets can slow it down.
Hair sometimes tangles around the main brush, so you may need to clean it every week if you have pets.
On Mixed Floors
When moving between carpet and tile, the robot adjusts itself smoothly. The transition is quick and accurate. You don’t need to worry about it dragging a wet mop across a rug.
Edge and Corner Cleaning
This is one of the X40 Ultra’s strongest points. Most robot vacuums struggle near walls, but the X40’s extendable mop reaches those areas better. It leaves fewer missed spots along baseboards.
5. Mopping Quality
The X40 Ultra doesn’t just drag a damp cloth around. It scrubs the floor with pressure and movement. The mop pads rotate while moving, so the cleaning motion resembles a light polishing effect.
The dock cleans the mop pads using warm water. Some versions even heat the water to remove grease or stubborn dirt. After washing, the dock dries the mop pads with warm air to prevent smells or mold.
In everyday use, the mopping system removes sticky spots, muddy footprints, and light spills easily. It can’t replace a deep manual mop for heavy stains, but for daily maintenance, it keeps floors spotless.
6. Battery and Runtime
The 6,400 mAh battery gives strong endurance. In standard mode, the robot can clean for about three hours before recharging. In high suction mode, that time drops slightly.
When the battery runs low, the robot returns to the dock, recharges, and then continues cleaning from where it left off. It doesn’t restart from the beginning. This “resume cleaning” feature helps it cover very large homes efficiently.
7. Navigation and Mapping
The navigation system is fast and accurate. The LiDAR sensor spins on top of the robot to scan the room. It measures distance to walls and furniture to build a precise map. The front camera adds another layer of intelligence by recognizing obstacles.
The X40 Ultra avoids socks, shoes, toys, cables, and even small furniture legs. The camera detects objects and adjusts its path to avoid them instead of bumping into them.
The robot also remembers multiple floors. If you have a two-story home, you can map both levels. When you move the robot upstairs, it recognizes which floor it’s on and starts cleaning accordingly.
In daily use, it rarely gets lost or stuck. It handles dark carpets, bright sunlight, and uneven floor levels well.
8. App Experience
The Dreame app is clean and simple. You can see a live map of your home, with rooms labeled clearly. The app allows you to:
- Set cleaning schedules
- Adjust suction and water levels per room
- Create no-go zones
- Save multiple maps
- Choose between vacuum only, mop only, or both
You can even set the robot to clean certain areas more than once. For example, you can tell it to mop the kitchen twice but vacuum the living room only once.
The app sends notifications when it finishes cleaning, when the dock needs attention, or when filters need changing.
9. Maintenance and Upkeep
The X40 Ultra takes care of itself more than most robots, but you still need to perform a few tasks.
- Dust bag replacement: The dock empties the dustbin automatically, but you must replace the dust bag every few weeks depending on how much debris your home collects.
- Water tanks: The clean water tank must be refilled occasionally, and the dirty tank must be emptied.
- Brush cleaning: Long hair can wrap around the main brush, so check and clean it weekly.
- Mop pads: The dock washes and dries them, but you should replace the pads every few months for best results.
- Filter: The robot’s filter needs cleaning under running water once a month and replacement every few months.
Overall, maintenance time is far lower than with traditional vacuums or simpler robots.
10. Noise Levels
The X40 Ultra runs quietly in standard mode. It sounds like a soft hum rather than a vacuum roar. In max suction, the noise becomes louder but still acceptable for daytime use. The dock’s auto-empty process creates a brief loud noise for about ten seconds, which is normal for all self-emptying vacuums.
11. Pros and Cons
Pros
- Extremely strong suction power
- Excellent edge and corner cleaning
- Smart obstacle avoidance
- Liftable mop pads protect carpets
- Long battery life and efficient path planning
- Automatic dust emptying, mop washing, and drying
- Clean and detailed mapping system
- Easy app control and scheduling

- Replacement bags and mop pads add ongoing cost
- Hair can tangle on the roller
- Occasional app bugs or Wi-Fi issues after updates
- Doesn’t deep-clean heavy carpet stains like upright vacuums
12. Comparison with Competitors
The main rival of the Dreame X40 Ultra is the Roborock S8 MaxV Ultra. Both offer strong suction, LiDAR mapping, and self-cleaning docks. The X40 Ultra has stronger suction on paper, slightly longer battery life, and a better edge-mopping feature. The Roborock focuses more on obstacle recognition with its camera system.
If you want deep carpet cleaning and perfect AI avoidance, the Roborock may have a small edge. If you want stronger suction, better mopping, and more automation, the Dreame wins.
Compared to Dreame’s own newer X50 Ultra, the X40 Ultra feels more mature. The X50 adds experimental features like step climbing, but it costs much more. The X40 remains the better value for most users.
13. Real-World User Feedback
Users love how little effort the X40 Ultra requires. Many people say they only handle maintenance once a week. The dock handles everything else.
Pet owners appreciate how well it collects fur and dirt from corners. Busy families enjoy the convenience of scheduled cleanings. A few users mention occasional app connectivity issues, but these usually fix themselves after restarting Wi-Fi or updating firmware.
The machine rarely gets stuck, even in cluttered rooms, and it finds its dock reliably.
14. Price and Availability
The Dreame X40 Ultra sits in the premium category. Depending on region and offers, the price usually ranges around the equivalent of ₹70,000–₹80,000 in India or about $800 internationally. During big sales, prices can drop sharply.
At that price, it’s not cheap, but when you consider it replaces both a vacuum and a mop — and cleans itself — the value becomes clear.
15. Who Should Buy It
You should buy the Dreame X40 Ultra if:
- You live in a home with a mix of carpets and hard floors.
- You want daily cleaning without effort.
- You have pets and need powerful suction.
- You have enough space for the dock.
- You value time more than manual cleaning chores.
You might skip it if:
- You live in a very small apartment.
- You have only carpets and no need for mopping.
- You want a cheaper, basic vacuum without automation.
- You don’t want to deal with apps or Wi-Fi setup.
16. Final Verdict
The Dreame X40 Ultra stands among the most advanced robot vacuums available in 2025. It combines excellent suction power, smart navigation, and a powerful mopping system. It doesn’t just clean; it maintains itself.
You will pay a high price for the technology, but you’ll also save hours of cleaning every week. It suits families, pet owners, or anyone who wants to reduce housework.
The machine feels reliable, modern, and capable of handling daily cleaning for years. Its design, performance, and automation show how far robot cleaning technology has come.
If you want a robot that vacuums, mops, empties itself, washes its own pads, and rarely needs your help, the Dreame X40 Ultra is the one to get.
In simple terms:
The Dreame X40 Ultra does everything — and it does it well.
