Cleaning pet hair is something I struggle with in my home. It's on my floors, my couches, my clothes, and even my dining room table. The only way I've been even remotely able to keep up with it is by running a robot vacuum every day -- who has the time to run a handheld vacuum daily? If you do, you have my respect. Truly.

When the Eufy X8 Pro showed up on my doorstep, promising to be the pet hair cleaning expert, I immediately put it to work. Eufy claims this robot vacuum has an active detangling roller brush that prevents it from clogging up pet hair. The company also says this is the first vacuum to feature dual TurboCyclone Suction motors (two fans that run at 4,000Pa). To test these claims, I gave the vacuum the entirety of my home for a month. Let's talk about how it did.

The Eufy X8 Pro has several distinctive features, including a dual TurboCyclone Suction, an industry first. The X8 Pro has two 4,000Pa vacuum motors that vacuum up every little bit of dirt and debris scattered throughout the home.

With four different suction levels -- quiet, standard, turbo, and max -- I found that my carpets and rugs generally come out with beautiful carpet lines and are hair-free after cleanings. When the robot detects softer surfaces, the BoostIQ feature kicks in, ramping up the suction power to lift all the dirt and debris out of the carpet.

When cleaning the rest of my home, sections of which are tiled, I found that the X8 Pro could get a little carried away with its side brush. Occasionally, instead of the brush kicking the dirt and debris into the brush roller, it would fling the pieces elsewhere, sometimes where the vacuum had already cleaned.

This seemed to happen more with debris like stray cat litter and pieces of dirt rather than pet hair or dust bunnies. This isn't a big deal if you're running the X8 Pro daily, but you might be disappointed in its cleaning capabilities if you're hoping for it to clean everything on a single run.

The Eufy X8 Pro is a two-in-one machine, but the mopping functionality is best described as just a wet pad to get dust off your floor rather than a deep clean. I've never been a fan of this wet mop head mechanic because it often builds up dirty water and uses that to drag along the floors. 

If you don't have kids or pets who shuffle around the house, the wet pad may tickle your fancy, but my home has all those things, so a true mopping feature is a must-have. Here's a list of great two-in-one machines that will do your floors justice.

Despite this, the Eufy X8 Pro is an intelligent robot vacuum that uses iPath Laser Navigation to clean in neat, consistent rows. It mapped my home's layout quickly and efficiently, and even attempted to divide the space into areas that it thought were different rooms.

Both these features worked well and made the app very straightforward to understand. Unfortunately, the X8 Pro lacks object avoidance. I was in trouble if I didn't pick up the cords, toys, and stuffed animals before the Eufy did its thing.

For some people, this isn't an issue (myself included) on certain days. Sometimes I have my life together and my floors look clean and pristine, but that's usually not the case. I lost a lamp cord and a baby toy to the X8 Pro.

Lastly, Eufy says the X8 Pro will keep its rollers tangle-free, a bold claim considering how difficult it can be to manage pet hair. Between my long hair and the fur from my German Shepherd, German Shorthaired Pointer, and cat, robot vacuum rollers are often clogged after they make their way around my home. Unfortunately, the Eufy X8 Pro had a similar ending; after every clean, I had to manually unclog the rollers.

ZDNET's buying advice

Who should buy this robot vacuum? After weeks of testing, my conclusion is that for soft surfaces like carpets and rugs, the Eufy X8 Pro is an amazing cleaner, especially for the mid-range price point -- and its $400 Prime Big Deal Days price makes it a steal. It also does a great job on my tile floors, even with the occasional mishap from the side brush. That said, don't buy into the Pro-Detangle Comb marketing, especially if you have several furry friends around the house.
