Dreame is a well-known name in the world of smart and automatic vacuum cleaners, with the Dreame X40 Ultra being one of its popular products in its lineup. The company has recently launched the Dreame X50 Ultra, which has even more smart features and AI under its wings.

The X50 Ultra boasts a climbing feature, wherein it can climb up a single step. Yep, you read that right! On the other hand, the X40 Ultra brings together a multitude of features that eventually help in doing a spotless cleaning job.
This brings us to the question: how does the Dreame X50 Ultra match up against the Dreame X40 Ultra? Well, that’s what we are going to find in this post today as we pit the Dreame vacuums against each other to find out which is the better vacuum cleaner for smart home enthusiasts.
Specs at a Glance
| Features | Dreame X40 Ultra | Dreame X50 Ultra |
|---|---|---|
| Suction Power | Up to 12,000Pa | Up to 20,000Pa |
| Battery Capacity | 6,400mAh | 6,400mAh |
| Battery Life | Up to 198 Minutes | Up to 276 Minutes |
| Removable Batteries | No | No |
| Mopping system | Wet and Dry | Wet and Dry |
Design & Build Quality
When it comes to the design, both the Dreame vacuum cleaners look almost alike. They have the typical look of robovacs. For example, the X40 Ultra comes with a base station for charging and two containers for clean and dirty mop water.

That said, don’t let the compact design fool you, for this vacuum cleaner can extend its side brush. This lets it clean along edges and corners easily and conveniently. Interestingly, this robovac can drop and pick up its mop pads automatically.

The Dreame X50 Ultra is sleeker and more polished in terms of looks. Together with the docking station, it can take up considerably more space. However, its list of pros outweighs its cons. For one, it’s well built, and all the moving parts are easy to clean and maintain.
Its signature HyperStream detangling Duo brush doesn’t trap hair and lint. And even if it does, it’s easy to clean since hair does not get tangled tightly. At the same time, the docking station keeps the dirt compartment and the mop pads clean and free from dust, and the water tanks are easy to clean.
Now, let’s come to the highlight – the X50 Ultra comes with Dreame’s VersaLift technology, which enables it to retract the DToF LiDAR sensor into the body, allowing it to crawl under low furniture. So areas like the underside of your bed and sofas stay clean and dirt-free.
Cleaning Performance and Navigation
No robovac is worth the money if it can’t do the basic job of cleaning floors, stairs, and carpets. With the Dreame X40 Ultra, you get a plethora of sensors that help it navigate your home without bumping into pets and other obstacles while also detecting dirt and dust.
The older Dreame robovac has a maximum suction power of 12,000Pa and comes with four suction levels – Quiet, Standard, Turbo, Max, and Max+, and you can adjust the power as per the scene in front of you.

Like most modern vacuums, the X40 Dreame creates a 3D map of your house. The map is pretty accurate. You can schedule the cleaning activities and forget about the rest. Nonetheless, note that the Max+ suction power is not available for scheduled cleans. You can only use it for one-off cleaning. That said, it avoids snoozing pets and furniture like a pro. Interestingly, it keeps a record of any interactions for your review later.
However, do not expect this vacuum cleaner to be super fast. It needs its own sweet time to clean. Thankfully, it can vacuum and mop at the same time, which significantly saves time and effort. Being a flagship, the X50 Ultra has a higher suction power of 20,000Pa, giving it a clear edge in both dry vacuuming and mopping. From sticky spots of dry liquid to climbing atop small stairs, it can do it all. That’s not all. It has an extendable mop on a robotic arm that allows it to clean edges with ease.

Thanks to its robotic legs, it can climb a single step of 4.2 cm (and combined steps up to 6 cm). Its real-world scenarios are also in sync with its spec sheet, and it cleans irregular flooring well.
Like its predecessor, the Dreame X50 Ultra’s mapping is on point. From pets to wires and furniture, it does a pretty great job of keeping away from obstacles. That said, you may still have to revert to hand vacuuming carpets and rugs. Like its predecessor, it can also auto-detach mop pads when it detects carpets and rugs.
Battery Life & Charging
The X40 Dreame Ultra is powered by a 6,400mAh battery which gives it a maximum run time of 198 minutes of mopping and vacuuming in standard mode. Of course, the run time will decrease when you use the Max+ mode for a longer duration. At the same time, it has a pretty long charge time, which means it can deep clean and mop any standard-sized home without needing refueling.

Charging up the battery doesn’t take much time, and you will have a fully charged battery in around 4.5 hours.
Like its predecessor, the X50 Ultra has a 6,400mAh battery which gets you a battery life of more than 200 minutes, which translates into a long run time.
That said, note that the vacuum takes a slightly longer time to do a deep clean. So, a full charge may get you just enough to get through a standard-sized house. The good news is that this robovac does an exceptional job of cleaning up spills, dust, and dirt.
Final Verdict: Which One Should You Buy?
Being a flagship successor to the X40 Ultra, the X50 Ultra comes with improved features. Not only do you get AI voice commands and enhanced automation, but also improved cleaning performance, thanks to the higher suction power. And features like precise navigation, mop-lifting, and better dustbin-emptying capabilities help make your life easier. Even so, it’s almost $300 more expensive than the X40 Ultra.
So if you can make do with slightly slower and less precise cleaning, the Dreame X40 is a good option. While it doesn’t have robotic legs to lift it up, it does a pretty great job in cleaning and mopping.
