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.

Dreame D9

The Dreame D9 robot vacuum cleaner offers impressive performance and functionality at a price that doesn't break the bank. One of its advantages is its ability to adapt to different surfaces by lowering the suction power of carpets, which not only makes it more efficient, but also extends battery life.

Dreame D9 takes cleaning to the next level by mapping your home, allowing for a more structured and efficient cleaning. It can also divide your home into different areas to ensure that all areas are properly cleaned.

Like most robotic vacuum cleaners, the Dreame D9 has some challenges when it comes to reaching corners and managing thresholds, but these are no more pronounced than what you would experience with more expensive models.

A unique feature of the Dreame D9 is its dual function as both a vacuum cleaner and a mop. The mop function is a practical complement because it can take care of micro dust particles that the vacuum cleaner may miss. However, it is worth mentioning that the mop function lacks vibration, which can make it difficult to deal with more difficult stains.

While some of the premium features found on more expensive models are missing from the Dreame D9, this is offset by its affordable price and overall impressive performance. It is a strong competitor in the robot vacuum cleaner market that delivers powerful cleaning without emptying your wallet.
