Dreame X40 Ultra Complete: review of the most complete robot vacuum cleaner

The Dreame X40 Ultra Complete arrives with a clear proposition: clean almost everything by itself and do so with a precision that previously required going over the house several times. Its combination of 12,000 Pa of suction, mopping with an extendable mop and a base that washes, dries and empties the dust places this model at the top end of the home market, right where the most ambitious robots of the moment compete.

In practice, what sets this unit apart is not only its suction power, but the way it divides the work between the robot and the station. It lifts brushes and mops when needed, detects dirt with advanced sensors and adapts the route to carpets, edges and low furniture. That makes it a machine designed for homes with pet hair, difficult corners and mixed flooring, without demanding constant attention every few hours.

A design built to clean where others fall short

The key to the X40 Ultra Complete lies in its ability to combine brute force and mechanical finesse. The liftable and extendable side brush gets close to skirting boards, table legs and corners where fine dust usually accumulates. On top of that, it adds RoboSwing MopExtend technology, which pushes the mop outward to get under low furniture and cover areas that in other robots are left as an overlooked strip, the size of a lingering shadow.

That combination gives more meaning to the concept of edge cleaning. It does not just go through the center of the room; it looks for the edge, the corner, the narrow gap, the area where lint gathers with a week’s worth of dust. In a flat with low sofas, beds with little clearance or heavy furniture, that extra extension can make a visible difference in a single day of use.

There is also a technical detail worth noting: the robot not only extends elements, but also raises the side brush, main brush and mops depending on the operating mode. This separation between vacuuming and mopping reduces the risk of dragging moisture or wetting carpets. In real homes, where hard floors, textiles and food crumbs or sand coexist, that logic matters more than the marketing headline.

Suction power you can feel in your daily routine

The 12,000 Pa are not a decorative figure. In everyday use, they translate into faster pickup of hair, crumbs and heavier dirt, especially on hard surfaces and low-pile carpets. You do not need to use maximum power all the time; in fact, one of the most useful aspects of the X40 Ultra Complete is that it vacuums well even in intermediate modes, which helps balance noise, consumption and results.

For homes with pets, this balance is especially relevant. Hair does not just settle in a visible strip; it tangles around edges, sticks to furniture legs and hides in transitions between surfaces. Here the robot responds with solid suction and with the support of a TriCut anti-tangle brush that can be purchased separately to further improve the handling of long fibers, dense carpets and accumulated hair.

Navigation also affects the feeling of power. When the robot maps well and strings together clean passes, the house gets finished sooner and with fewer repeats. The X40 Ultra Complete can create maps of up to four levels and work by rooms or specific zones, a clear advantage in large flats or multi-story homes. Instead of moving like an erratic device, it follows an orderly and predictable cleaning pattern.

Smart mopping with hot water and humidity control

Mopping is the model’s other major selling point. The base washes the mops with 70 °C hot water and then dries them with hot air, a combination designed to reduce stains, greasy residue and odors. The robot also adds humidity control in 32 levels from the Dreamehome app, so the user can adjust mopping for delicate floors, drier areas or intensive cleaning.

In daily use, this capability becomes noticeable when the floor receives different kinds of dirt. A damp footprint is not the same as a drop of sauce or an area with dried mud. The OmniDirt system helps distinguish that dirt using color sensors and analysis of dirty water, and this allows the robot to wash the mop again or go over an area if it detects that the result has not met expectations.

That double washing and automatic double mopping make sense in kitchens, entryways and homes with children or animals, where dirt appears in layers. The robot does not behave like a mechanical mop with autopilot, but like a tool that adjusts intensity according to the actual state of the floor. That difference prevents overworking a clean area and concentrates effort where it is actually needed.

Carpets and rugs, the terrain where intelligence is measured

One of the clearest tests for any robot vacuum is how it behaves on carpets. The X40 Ultra Complete responds with several strategies: it can remove the mops completely, raise them up to 10.5 mm, avoid the carpet or intensify suction to capture heavier debris. It does not treat all carpets the same, and that is precisely what gives it value in a mixed home.

Short-pile carpets are the most favorable scenario. There the robot can vacuum without leaving moisture behind and without getting stuck when transitioning surfaces. On thicker carpets, it is advisable to review the setting in the app to prevent the mop from touching fibers that are too long and creating unwanted dampness. The manufacturer itself indicates that, for medium or long pile, the safest option is to set exclusion zones or avoid mopping that material.

In real-world use, this flexibility matters because a home is not made up of ideal surfaces. There are doormats, hallways with thin carpet, decorative rugs and textiles that shift around. A less prepared robot could leave wet areas or push a light rug toward the wall. The X40 Ultra Complete, by contrast, tries to solve that domestic chaos with different rules for each texture and a fairly fine reading of the environment.

Autonomous base: maintenance stops being a daily chore

The base station is almost an appliance within an appliance. It empties dust into a 3.2-liter bag, washes the mops, dries them with hot air, and refills water and cleaning solution. Dreame talks about up to 75 days of automatic emptying under laboratory conditions, a useful reference for understanding the system’s capacity even though the real frequency will depend on the size of the home, pets and how much dirt there is.

There is another less flashy but very practical advantage: the base reduces noise when emptying the bin compared with more abrupt solutions. It does not make the operation silent, but it does soften that industrial-vacuum feeling that appears in some models when dumping dust. In a small apartment or during a nighttime cleaning, that nuance can be more pleasant than it seems on paper.

The water connection kit takes automation a step further, as it can refill and empty tanks autonomously. That said, it is sold separately and compatibility depends on the region. Even without that accessory, the base already offers an experience very close to true hands-free use. What usually remains is checking the clean water, emptying the dirty water and, from time to time, cleaning a moving part.

Navigation and object recognition make the difference

The X40 Ultra Complete uses 3D structured light, an RGB camera with artificial intelligence and recognition of more than 120 objects to avoid collisions with cables, shoes or toys. This visual reading means the robot does not rely only on a preset route; it observes, interprets and corrects. In a lived-in home, where there is always a backpack on the floor or a charger cable left out, this reduces jams and interruptions.

The integrated LED also helps in dark rooms. That is no small detail. Many robots perform well in good light and become disoriented when evening falls or when they clean under furniture where little light reaches. Here the device maintains steadier navigation and can plan precise routes even in shadowy areas, something that is especially noticeable in bedrooms and interior hallways.

Obstacle detection is not infallible, because no system of this kind is, but it is above what more basic models offer. For anyone living with pets, the critical point is not just vacuuming hair, but avoiding cables, water bowls, toys and tricky corners without turning cleaning into a game of chance. In that area, the X40 Ultra Complete shows notable technical maturity.

The app and voice control make cleaning more flexible

The Dreamehome app concentrates much of the product’s value. It allows you to adjust power, humidity, cleaning modes, no-go zones, room-by-room cleaning and strategies for homes with pets. It also offers floor-type recognition and the option to define different routes depending on the room, which is useful when the dining room has parquet and the kitchen has ceramic tile, or when one room gets more traffic than another.

The robot integrates with Alexa, Siri and Google Home, so it can start or return to the base with simple voice commands. This is not a system that replaces the app, but rather an additional layer of convenience. The real value still lies in the interactive map, where you can see how the device organizes the work and how it learns the home as if memorizing a score.

Among users, opinions often converge on one idea: the app offers many options, although at first it can seem dense. That abundance is not a problem if you understand it as a fine control panel. Someone who just wants to press a button and be done may not fully exploit the potential; someone who adjusts levels, rooms and cycles finds a much more customizable robot than average on the market.

Battery, runtime and real cleaning times

The 6,400 mAh battery gives room for long cleaning sessions and returns to the base when needed to resume afterward. In real conditions, the X40 Ultra Complete can work through a broad session in medium or large homes without becoming a project split into too many stages. That capability reduces human intervention and improves the sense of continuity.

The charging mode during cheaper hours adds an interesting energy-saving layer for anyone who organizes cleaning at night or during lower-tariff periods. It is not a feature that transforms the bill on its own, but it does fit the logic of a connected home that also seeks efficiency in small power draws. Automation here not only saves time; it can also better organize spending.

In everyday cleaning, the robot is not designed to chase the surgical perfection of a professional manual vacuum. Its strength is keeping a home clean every day with minimal intervention. That is the right measure for evaluating its autonomy: not the occasional peak performance, but the frictionless consistency that leaves the floor ready with almost no visible effort.

What the Complete version includes and why it matters

The Complete edition stands out for the included accessory package. In addition to the station, the robot and the pre-installed components, it adds the main brush, side brushes, filters, dust bags, mop pads and cleaning solution. In other words, it does not arrive bare, but with a set that lets you start using it with fewer immediate purchases and with a reasonable запас for the first few months.

That detail matters because in high-end robots the cost does not end at the box. Consumables are part of the real expense, and it is worth looking at how long each part lasts, how many spares are included and how easy they will be to find later. The Complete version reduces some of that initial uncertainty and makes the unboxing more rounded, especially for anyone looking for a closed purchase with no pending accessories.

This version should also be understood as a way to get more out of the product from day one. It does not change the robot’s technical core, but it does change the user experience. Having more replacements at home avoids interruptions and gives room to keep the system in good shape without immediately needing an extra purchase. In a device so focused on autonomy, that gesture fits the model’s overall philosophy.

Compared with its predecessor, the leap is in the details you notice

Comparison with the X30 Ultra shows concrete improvements: more suction power, better cleaning along edges and corners, an extendable side brush, hotter water and a more refined handling of obstacles and dirt detection. It is not a complete reinvention, but rather an evolution that corrects several common weaknesses of the previous generation.

Where the difference is most noticeable is at the margins. The X40 Ultra Complete reaches walls better, enters low gaps more decisively and handles the transition between vacuuming and mopping more effectively. Those kinds of improvements are not always visible on a quick spec sheet, but they are visible in the routine: fewer forgotten spots, less manual touch-up, and fewer moments when the user thinks another pass would be necessary.

Against cheaper or simpler models, the comparison is even clearer. This robot does not compete on power alone, but on coordination of functions. The mop lifts when it should, dries when finished, the base cleans the washing surface and the map adapts to the environment. The sum of the automations is what makes the X40 Ultra Complete a high-end product, not a single spectacular number in an ad.

What to keep in mind before choosing it

There are three points that deserve a cautious look. First, the price: it is an expensive robot and only makes sense if you are really going to use the autonomous base, mopping and advanced navigation. Second, the height of the device and the geometry of some furniture can limit access to certain spaces. Third, privacy always requires some attention when there is a camera and remote control in the home.

It is also worth remembering that no advanced function completely eliminates the need to prepare the space. Picking up cables, small toys or loose textiles still helps a lot. The robot can handle quite a few obstacles, but a less cluttered home always allows for better results and smoother navigation. Technology helps, yes, but it does not perform miracles among shoes left out of place and awkward chair legs.

That is why the X40 Ultra Complete is a better fit for profiles that value convenience, customization and low maintenance. It is especially logical in homes with pets, mixed surfaces and frequent mopping use. Someone who only wants quick, hassle-free vacuuming may not need such an advanced machine. Someone who wants to minimize daily intervention, however, will find a very mature tool here.

A robot aimed at continuous cleaning, not a one-off gesture

The Dreame X40 Ultra Complete does not aim to be just a vacuum with a pretty base. Its ambition is greater: to become a domestic cleaning system that works like a discreet, almost invisible, but constant presence. Its strength lies in the coordination between suction, mopping, detection and self-protection, a choreography of parts that correct one another to avoid obvious failures.

In a market full of robots that promise a lot and deliver only partially, this model stands out because it does several tasks well at once. It vacuums forcefully, mops with control, protects carpets, avoids obstacles and reduces manual maintenance to a minimum. It is not cheap or perfect, but it is complete enough to justify the interest it sparks among those looking for true high-end performance and not just a flashy label.

The image it leaves after several days is that of a device that sees the home as a changing map, not as an empty room. That nuance changes everything. Where others leave traces of improvisation, the X40 Ultra Complete tries to impose order. And in a normal home, with dust, hair, crumbs and rush, that everyday order is worth more than any loud promise.
