Our Verdict
The Dreame X40 Ultra is a technological marvel that sets new benchmarks in robot vacuum performance. With its industry-leading 12,000Pa suction power, it outmuscles virtually every competitor on the market. Combined with innovative features like the extending side brush and hot water mop washing, this is a premium cleaning solution for demanding users.
What truly sets the X40 Ultra apart is its attention to detail. The extending side brush automatically extends when approaching walls and corners, ensuring thorough edge cleaning that other robots miss. The hot water mop washing system keeps pads hygienic and removes stubborn stains more effectively than cold water systems.
Unmatched Suction Power
The 12,000Pa suction is not just a marketing number - it delivers real-world results. In our carpet deep cleaning tests, the X40 Ultra extracted embedded dirt from high-pile carpets that other premium models left behind. Pet hair, fine dust, and even ground-in debris are no match for this powerhouse.
On hard floors, the extreme suction ensures that even the smallest particles are captured in a single pass. We found it particularly effective on textured tile and grouted surfaces where dirt tends to hide.
Innovative Edge Cleaning
The extending side brush is a game-changing feature. As the robot approaches walls or corners, the brush automatically extends outward by 4cm, sweeping debris from hard-to-reach areas into the cleaning path. This results in noticeably cleaner baseboards and corners compared to fixed-brush designs.
Hot Water Mop Washing
The base station heats water to 60°C (140°F) to wash the mop pads, effectively removing bacteria and stubborn stains. During testing, we found that pads stayed fresher longer and maintained better cleaning performance across multiple sessions. The hot air drying prevents mildew and odors.
Navigation and Obstacle Avoidance
LiDAR mapping combined with an RGB camera provides excellent spatial awareness and object recognition. The X40 Ultra successfully identified and avoided common obstacles like shoes, cables, and pet waste during our testing. Mapping is fast and accurate, typically completing whole-home maps in under 15 minutes.
Who Should Buy This?
The Dreame X40 Ultra is perfect for:
- Pet owners with heavy shedding (cats, dogs)
- Homes with thick carpets requiring deep cleaning
- Users who prioritize edge and corner cleaning
- Those seeking the most powerful robot vacuum available
The premium price point means this isn't for everyone. If you're on a budget, consider the Eufy X10 Pro Omni which offers strong performance at a more accessible price.
