Eufy X9 Pro Review: Great But Missed Things

Eufy’s latest flagship robot vacuum has all-new mopping technology, an auto mopping station that washes and dries its mop pads, and an AI obstacle avoidance system. And as you’ll see in this Eufy X9 Pro review (CleanerBot with MopMaster), there are some aspects that are literally the best we’ve ever seen. But there are also some pretty significant drawbacks to the X9 Pro to consider as well. We’ll go over all the pros and cons today.

The Basics

As far as Eufy robot vacuums are concerned, the X9 Pro is more advanced in almost every way than their previous 2-in-1 robot vacuum and mop combos. Eufy never released the X8 Hybrid (Amazon) with an advanced dock, so its closest predecessor would be the L35 Hybrid+.

The Eufy X9 Pro is priced in what we would consider the upper mid-level range. So, we shouldn’t expect it to perform as well as robot vacuums close to twice its price, such as the Roborock S8 Pro Ultra. 

For the purposes of this Eufy X9 Pro review, we’ll be comparing the X9 Pro quite a bit to the Roborock Qrevo, which is in the same basic price range and has most of the same features.

Unboxing and Setup

The X9 Pro and dock come completely assembled. So, setup just requires following the instructions in the Eufy Clean App and allowing the X9’s battery to fully charge.

Pros

Mopping

The Eufy X9 Pro has a really good mopping system. It uses two spinning 180 RPM mop pads that exert one kilogram of downward pressure to scrub floors. 

In our evaluations, mopping performance was as good or better than any robot vacuum mop combo we’ve assessed. It did perfectly with the dried-on grape juice and dried-on coffee torture evaluations, as well as with the glow-in-the-dark evaluations. This is an area where the X9 Pro excels.

One cool thing is that the mop pads on the Eufy X9 Pro lift up automatically when it detects carpet. So, if you have a mix of hard floors and carpets in your home, you can just do one run to vacuum and mop the whole house at the same time. 

This makes the X9 Pro much more efficient, and in our opinion, it’s the clear future of robot vacuum mop systems.

12mm Mop Pad Lift

One thing that’s new with the Eufy X9 Pro is it will lift its pads 12 millimeters, which is the highest we’ve seen yet. For example, the Roborock Qrevo only lifts its pads 7 millimeters. So, the X9 Pro easily clears all types of carpets and keeps them dry.

Auto-Clean Station

Another pro is the new charging dock and bin system called the Auto-Clean Station. You simply fill one of its large tanks with clean water, and it will automatically wash the X9’s mopping pads, fill its water tank, and empty its dirty water. You can set it to wash the pads more or less often in the app. 

It also dries the pads with heated air after each run, which is a top-tier feature. The robot vacuum basically has every feature you would want for a top-tier mopping system.

Navigation and Obstacle Avoidance

Its navigation and obstacle avoidance system are a massive advantage. The Eufy X9 Pro uses lidar on the top for basic navigation, but it also uses a front-mounted camera and 3D ToF sensors to avoid obstacles that are too low for its LiDAR or too light for its bump sensor to detect.

Eufy calls this new obstacle avoidance system “AI.See”, and we were impressed with it. At this point, we’ve evaluated most of the top-of-the-line robot vacuums that have some kind of obstacle avoidance system. However, until this review, no robot vacuum had gotten a perfect 12 out of 12 in our evaluations, but the Eufy X9 Pro did. 

This is one area where there is a massive difference in quality between the X9 Pro and Q Revo, which performed particularly poorly with this assessment. In contrast, the Eufy X9 Pro did exceptionally well.

We’re not sure if it did so well because of its ToF sensor (a kind of 3D spatial recognition process), but either way, we think it’s something of a breakthrough for Eufy and the robot vacuum world in general.

In our evaluations, mopping performance was as good or better than any robot vacuum mop combo we’ve assessed.

App Features

The Eufy X9 Pro has a great app and an excellent feature set. It mapped our house in five minutes, and everything was easy to use. It has most of the features you would expect from a top-of-the-line robot vacuum.

Navigation

In the navigation evaluations, where we ran the robot several times on different settings, we found that it was above average in almost every assessment. It was exactly tied with the Qrevo for navigation efficiency, which is well above average. It was also great with battery efficiency, which equates to about 1228 square feet per charge.

Carpet Deep Clean

The last pro we’ll mention is its carpet deep cleaning ability. We evaluated this by embedding sand into medium-pile carpet, where we found it to be pretty good.

Cons

Lacks Auto-Empty Feature

Our Eufy X9 Pro review wouldn’t be complete without discussing the cons. The first potential drawback is that the X9 Pro doesn’t have an auto-empty bin system. It has a bin that washes and dries the mop pads, but it doesn’t actually empty the robot’s dustbin automatically. That still needs to be done manually. 

Now, we know we are spoiled, but emptying the robot’s dustbin does seem to be job number one when it comes to having an advanced, automated cleaning machine like this. All the other robot vacuums with advanced docking stations have it, but the Eufy X9 Pro does not.

Recent examples of robot vacuums with both mop management and auto-empty capability include several Roborocks, as well as the Dreametech L10s Ultra and the Ecovacs Deebot T10 OMNI.  

Given the advancements in other robots, this omission from the Eufy X9 Pro feels like a step backward.

Surface Debris Pickup

Another con is its lackluster ability to pick up debris from the surfaces of hard floors and carpets. It does a decent job at this, but it was noticeably worse than others in this price range. 

After inspecting the underside of the robot, we suspect this may be due to the unusual placement of the brush roller at the front of the robot, as opposed to the middle, which is more typical and allows for better debris guidance by the side brush.

There are other robot vacuums with brushes placed at the front of the robot, but they usually have extra wide brushes to compensate.

Eufy X9 Pro Review: Conclusion and Recommendation

The lack of an auto-empty system and the poor performance of picking up surface debris are our only two main criticisms of the Eufy X9 Pro. You could overlook them, especially if you value mopping, navigation, and obstacle avoidance. It’s still a very strong robot vacuum for households.

However, we see the X9 Pro as a missed opportunity for Eufy overall. For us, the Roborock Qrevo, despite its underwhelming obstacle avoidance scores, remains our top choice in this price range, at least for now.
