Dreame X40 Ultra review: performance and evaluation
For our Dreame X40 Ultra review, we put it through various real-world assessments to determine its performance, and it performed impressively well.
Power
The Dreame X40 Ultraโs power is impressive. Dreame claims it has 12,000 Pascals of suction, significantly more than its predecessor, the X30 Ultra. And we more or less confirmed Dreameโs claim in our bench evaluations.
This model scored significantly higher in both suction and airflow evaluations than the X30 and surpassed the average scores by a wide margin.
Carpet deep clean
In our practical performance evaluations, the X40 Ultra far exceeded expectations. Notably, it did phenomenally in our carpet deep clean evaluation, which measures its ability to pick up deeply embedded debris such as sand in carpets.
As you can see, the X40 Ultra outperformed the X30 and surpassed the average scores out of 90+ evaluated robot vacuums, which is a significant improvement.
Despite Dreame’s advancements in features and navigation, their last few models have lagged in power and performance metrics, scoring below average in our evaluations. However, the X40 Ultra marks a change, now offering the power to complement all those impressive features.
Debris pick up
The X40 Ultra also excels at its primary task of sweeping up debris from hard floors and carpets. It delivers nearly perfect results, equipped with a single-side brush and a main silicone brush in a floating brush housing.
It effectively picked up everything from fine to extra-large debris on both surface types, meeting the high expectations for a robot in this price range.
Hair pick up
It also performed well at picking up pet and human hair. However, longer hair did tend to get tangled in its brush, which is unfortunately quite common for robot vacuums.
Dreame X40 Ultra robot vacuum features
Edge cleaning
The Dreame X40 Ultra robot vacuum has a swinging side brush designed for improved corner cleaning, which performed decently in our evaluations. It also features an automatic extending mop pad that swings out, enhancing its ability to clean edges effectively.
Advanced mop system
When it comes to mopping, the X40 Ultra is one of the most advanced robot mops weโve evaluated. Its mopping ability was awe-inspiring in evaluations involving things like the dried-on coffee and grape juice stains, where it visibly outperformed the Roborock S8 MaxV.
While both models have great mops, the Dreame X40 Ultra, with its spinning pads, seems more effective for tough stains, although a more objective evaluation method is needed.
Also, the robot vacuum mop combo can lift its mop pads up to 10.5 mm when it senses carpets to avoid getting them wet. That means you should be able to do a single run in your home if you have a mix of hard floors and carpets.
One unique feature weโve only seen on Dreame robot vacuums is the magnetic pads. When enabled in the app, the X40 will leave the mop pads on the base, vacuum the carpets first, and then return to the base to retrieve the pads for cleaning hard floors.
The X40 Ultra also has a brand new feature, which is it lifts its front side brush upon detecting a wet spot to keep it dry.
Thereโs also a Robo swing feature that enables it to mop hard-to-reach areas.
Additionally, when it spots particularly bad stains using its camera, it will give those areas extra attention while mopping.
Advanced base station
One of the Dreame X40 Ultra’s biggest advantages is its advanced base station. It automatically empties the dustbin into a large 3.2 L disposable bag, washes the mop pads with hot water, dries them with hot air, and fills the mop tank with fresh water and a cleaning solution of your choice. The trend towards non-proprietary solutions is a welcome development.
The base station also includes the innovative self-cleaning system introduced with the Dreame X30 Ultra, which uses a gear-driven mechanism and squeegees to wash the bin. It also features a sensor in the dirty water line that detects if the mop water is dirty and triggers another mop-washing cycle if necessary.
Obstacle avoidance
Regarding obstacle avoidance, the X40 Ultra features an impressive system that uses a camera, a structured light system, multiple lasers, and an LED light. While these components are standard, Dreame must be doing something right.
Thatโs because all of their recent models are tied for the top three spots for obstacle avoidance in our evaluations. Not to mention, the X40 is the second robot vacuum to achieve a perfect score.
Thatโs not to claim it will flawlessly avoid every small obstacle like Legos. However, it significantly reduces the need to pick up items beforehand, making it one of the most reliable robot vacuum options available.
Battery efficiency and navigation
In our various navigation and battery life evaluations, the X40 Ultra did very well, providing near-perfect coverage of the new floor plan without getting stuck.
It was fairly efficient, covering right around the average number of square meters per minute. Plus, it has one of the largest batteries in the industry, at 6,400 milliamp hours. Dreame claims it can run for 194 minutes on low power and cover over 3,300 square feet per charge.
In our “best settings” runโusing standard power with carpet boost and mopping features enabledโthe Dreame X40 Ultra achieved 1.96 minutes per percentage point, which is above average.
This means it can clean even very large floor plans in a single run. Additionally, it offers recharge and resume functionality, fast charging, and supports multi-level maps, making it highly versatile and capable of handling extensive cleaning tasks.
App
The Dreame X40 Ultraโs app is comprehensive and user-friendly, offering near-total control over every aspect of the robotโs behavior. You can adjust mopping settings, manage auto-bin emptying, and configure obstacle avoidance. The app also includes various mapping features, including virtual barriers, 3D mapping, room and zone cleaning, and advanced scheduling options.
Pet features
Several new pet-friendly features are also available. The X40 offers two-way video calling, allowing for remote interaction with pets.
It will also intelligently suggest pet zones to avoid food bowls and boost suction power around cat litter boxes for more effective cleaning.
Cons of the Dreame X40 Ultra
While the X40 Ultra is super impressive, itโs not perfect. Thereโs just one potential drawback to consider.
Price
It surpasses the Roborock S8 MaxV as the most expensive robotic vacuum evaluated so far, though the difference isn’t substantial. Other than that, the robot vacuum is practically perfect.
Dreame X40 Ultra Review: value and final thoughts
The Dreame X40 Ultra has indeed taken the top spot in our algorithm based on evaluation scores and features.
However, weโre not going to declare it the best on the market just yet, especially with a new flagship contender from Ecovacs scheduled for evaluation in the coming weeks. Final opinions on the best flagship robot vacuum for the spring or summer season will be reserved until then.
Nonetheless, the Dreame X40 Ultra sets a high bar and will be tough to beat. If you want a robot vacuum mop combo thatโs powerful, efficient, and packed with many useful advanced featuresโthe X40 may be right for you.
