Dreame X40 Ultra

The Dreame X40 Ultra is the latest addition to Dreame's impressive range of robot vacuum cleaners. After testing this robot vacuum cleaner for a few weeks, we can establish that it really lives up to expectations with its advanced features and powerful performance.

With an impressive suction power of 12,000 Pa, the Dreame X40 Ultra is able to absorb even the most stubborn dirt particles. Its AI-based obstacle avoidance system, which uses RGB + 3D structured light, ensures it effectively navigates around obstacles in the home without getting stuck.

The Dreame X40 Ultra comes equipped with a variety of customizable cleaning features. The liftable and extendable side brush allows it to adapt to different floor types and clean even in hard-to-reach corners. In addition, the mop can be extended and removed for easy cleaning, and the vacuum cleaner has a self-cleaning washboard that automatically washes and dries the mop with hot water at 70°C.

The large battery capacity of 6,400 mAh means that the Dreame X40 Ultra can clean your home for a long time without needing to be recharged. Its dust container holds 300 ml, while the water tank has a capacity of 80 ml. The separate tank for clean and dirty water holds 4.5 liters and 4.0 liters, respectively, which allows it to clean large areas without interruption.

In addition to the aforementioned features, the Dreame X40 Ultra also offers the possibility of voice control, making it easy to integrate into your smart home. The function of dirt detection and rewashing of floors with multispectrum sensors ensures that your home is thoroughly cleaned. Auto tank filling and cleaning agent additive make the maintenance of the vacuum cleaner easy and convenient.

With the camera, you can easily monitor your home, either by controlling the robot vacuum cleaner itself with the app or selecting a point on the map for the robot to go to. It may not be the best camera angle because the robot rides along the floor but definitely something we use from time to time.

Dreames app is stylish and well made. Tons of features and settings are available and it's easy to get started. The base station is has a stylish reffled design with gold details and comes in black and white.

Dreame X40 Ultra is a high-performance robot vacuum cleaner that combines powerful suction capacity with intelligent cleaning functions. If you are looking for a reliable and efficient robot vacuum cleaner that can handle everything from daily cleaning to deeper cleaning, the Dreame X40 Ultra is a great choice. However, it comes with a large price tag that is not suitable for all households.

Roborock Qrevo

Roborock has now expanded its range in the mid-size segment with the Q Revo, an incredibly capable robot vacuum cleaner. It is a wise strategy from Roborock to first launch its flagship S8 Pro Ultra at a price that is approximately SEK 6,000 higher and then follow up with the Q Revo, which in technical terms almost reaches the flagship level. Although there are some technical differences between them, the result they deliver is not that markedly different. Moreover, taking into account the price gap between them, Q Revo becomes the superior choice. The Q Revo obviously offers all the advanced features we recognize from Roborock's top models, including Lidar, obstacle avoidance, auto-lift-able mop, and self-emptying, among others. The base unit is slightly higher, but at the same time it holds a whopping 5 liters of water. The mop cleaning is carried out with a new type of base plate that requires minimal maintenance and, above all, eliminates the need to change parts, which differs from, for example, the S8 Pro Ultra and S7 MaxV Ultra.
