Previously I had another robot vac mop hybrid that was underwhelming to say the least and I spent close to $1300 on that unit. When it began making more of a mess than cleaning, I threw it in the bin and began looking for an actual replacement. After reading lots of reviews and watching numerous YouTube videos, I came up with the Roborock Qrevo CurvX as my top choice. I had very specific criteria for the beyond demanding environment this robot would be tasked with cleaning. First and foremost, I needed the best vacuum for pets and, in particular, a long hair German Shepherd that sheds fluffy tufts of hair off her hind quarters like leaves falling from the trees in autumn. Her hair has been a particularly challenging thing for all my robot vacs. Given that we acquire what I call "hair tumbleweeds" if one single day is skipped, I knew I was already asking a lot out of a robot vacuum. However, given the coarse nature of part of her top coat and the downy like wool from some of her undercoat, I also needed a vacuum that wasn't going to continually suffer from tangled main brush errors. Every other robot we've owned has wound up either strangling itself and its main brush with this hair or been unable to empty the dust bin regularly enough to prevent hair clumps from being left behind throughout the house. The last robot would leave what looked like dreadlocks of dog hair all over. It was gross. So my top 2 criteria: best robot vac for pets (a GSD was used in the Google search) and best robot for anti-tangle brush rollers.
I am not going to lie. My expectations for the Roborock were pretty low and I was skeptical of the whole hybrid vac/mop robot design. It took one use over one day to convince me otherwise! The robot arrived and the set up was easy to follow, much like the previous robot vac mop unit I had. I got everything charged and powered on and ready to go for the next day. I scheduled the unit to run at 8:00 am and clean the entire house using the vac and mop setting. I put everything at max because our house had been days without a robot running at that point so I really expected to get error messages while at work. When I walked through the front door, I could immediately tell a difference in the air quality. The air actually felt clean and the floors were spotless. Areas where our previous robot would miss, like hair that congregated in corners, were clean and without dirt, dust or hair. Since I added robot floor cleaning solution to the water tank, the floors in the house had a light, fresh scent. A quick walk through the house found every room had been cleaned thoroughly and I was stunned. Next, I decided to go inspect the robot to see how much hair was wound around the main brush. Again…I was stunned! The underside of the robot was clean as a whistle! There was no hair in the main brush at all. In fact, there was no hair around the large wheels on the side, the roller wheel at the front of the unit, or the sweeper brush. None! My last robot would always have hair tangled in all these spots and the dust bin would always be full even though the robot was supposed to empty the dustbin at the end of the cleaning session. This led me to the next huge surprise – the mop pads. They were bone dry, clean, and smelled fresh. I could not actually believe it and yes…I actually took the pad off the robot and smelled it to see if it smelled remotely musty or dirty. It was clean and dry. Given the first run was a success, I decided to wait and see how the robot did one week later. It has now been about two weeks since we had the CurvX and the robot has run every single day with the exact same results. It is quite simply, the best performing robot I have ever had (and I was an early adopter in the robot vacuum world).
Mapping – It mapped my home with 95% accuracy in the first run. In the second run, the map was 100% correct. It was also super easy to label the rooms in the map. 10 out of 10.
Obstacle Avoidance/Cords – Some online reviews on YT complained about the robot getting stuck on cables and cords. Like any robot, there is an expected amount of tidying up before it runs that should be expected. That being said, the obstacle avoidance has been phenomenal and I've had it encounter serval power cords for lamps, TV equipment, routers, etc. and it has never once even run them over. Instead it takes a picture and shows their location on the map after it's completed its job. 10 out of 10.
Vacuuming – We have either hardwood or tile in our home, but there are several large rugs in various locations and the previous robot left lots of long German Shepherd hairs in those rugs. I could take my foot and rub it across the rug and pile up a clump of hair easily. That is not the case with this robot. It cleans the rugs impeccably! Of course the hardwood is as easy as it gets, but the recognition to raise the mops when it encounters rugs has worked flawlessly and the robot has not made our rugs wet at all. The floors feel clean after this robot runs and that's probably because they are clean! This robot also goes to empty its dust bin with a great deal or regularity! 10 out of 10.
Mopping – Using the Smart AI feature has been a neat thing for this robot. It will detect where it encounters dirty areas whether that be in vacuuming or mopping, but it will elect to return to clean those areas again. In some spots, the robot has gone back two additional times to mop until it was satisfied it had cleaned the area well. Amazing! The floors get mopped well and the amount of water used, if not using the Smart AI, is easily adjustable through the app. One of the best features is that the mop pads are cleaned with HOT water and they are dried for 3 hours. The mops are also cleaned multiple times during any given session. I does not mop your home with nasty pads. 10 out of 10.
Roborocks App and Ease of Use – the app is extremely easy to use but also full of so many customizable features. There is a bit of a learning Curv (pun intended) for anyone who might be new to the robot vacuum world. However, it is quite easy to intuit and navigate even for beginners. My last robot had no way to send the unit back to the dock to empty the bin if I wanted to. I can do that with the CurvX and more. 10 out of 10.
Battery Life – This is the only spot where the robot struggles. It will take a VERY long time for the unit to clean my home. Sometimes the robot has to return to the base to charge twice before the job is complete. That being said, it's a trade off I'm willing to make for the level of cleanliness I get from the robot. I set it to run when I'm at work and it may start at 8 am and not finish until 2:30pm with charging times in between. I'd much rather have the robot take it's time and do a thorough job that exceeds my expectations as opposed to my previous robot that cleaned everything with one charge in about 2.5 hours only to leave me with more work to do when I got home. I wish it had a more robot battery and longer life because it does take it a considerable amount of time to charge. That being said, it's worth it, in my opinion. There may be other robots that clean just as well and can do so without having to charge so frequently. Just understand if you need something that will get the job done quickly and thoroughly, this is not your bot. 6 out of 10.
Fit In Tight Spots – This robot has a unique feature – the Lidar unit on the top of the robot will lower to give it access to go under tight spaces. Even though my last robot had more than enough clearance, it would not go under our bathroom vanities or living room couch. That's not the case with the Roborocks. It even vacuums under our Wolf Range/Stove. If this unit will fit, it will go there. My son remarked that he's seen this robot go in places the other one did not and he's absolutely right. This little guy is downright intrepid! 10 out of 10.
Sturdiness/Build Quality – everything about the Roborocks has been designed with ergonomics, function, and quality in mind. Everything feels sturdy and well-made. The design of the rollers is ingenious because the two part main brush definitely keeps hairs from tangling. Everything feels solid and well made with this unit. I have no qualms about the price I paid for this. It has been worth every penny.
Overall Rating – 9.8 out of 10. The only points lost are due to battery life, but taking everything else into consideration, this robot has exceeded every expectation I had for it's performance. It has been a trooper every single day since I got it. With proper maintenance and care, I hope to keep this little guy running for several years. If you are considering a robot vacuum, which I assume you are if you read this review, this is the one to get. I have an environment that would stop and has stopped all other robot vacs in their tracks – not the CurvX. It acts like GSD constant shedding is no big deal and for a vacuum with this much power and the anti-tangle designed brushes – it isn't a big deal. It just keeps on working. I love this little vacuum!
