I am very excited to be reviewing the RoboRock E25 Robot vacuum/mopping robot. After putting it though our battery of tests, we found it to be surprisingly good. Roborock did send me this E25 for free to review, but I like to think the tests we put robot vacuums through speak for themselves and leave very little room for favoritism on my part. So, links above for current prices and reviews, and let’s get started.


So, the E25 is the middle tier vacuum from RoboRock—not as expensive as their top of the line S5 but a bit more expensive than the budget version, the C10. One of the main differences between the E25 and the S5 is that while the S5 uses invisible lasers to map and navigate, the E25 uses a dual gyroscope and a Dual Optical motion tracking sensors, which they call an electric eye.


So, the E25 uses these sensors in conjunction with its pretty advanced algorithm for its smart navigation. While most vacuums in this price range just pinball around randomly to clean, the E25 navigates in straight, efficient line, while at the same time navigating around obstacles as well as incorporating edge cleaning in each run.


I, honestly, have no idea how it does this, but, to me, its navigation is virtually indistinguishable from the top of the line smart navigation bots which are two or even three times the price. This straight back-and-forth cleaning also helps reduce the overall cleaning time and generally cleans more efficiently. So, yeah—high marks for its smart navigation and obstacle avoidance. I, literally, can’t find anything negative to say about it.


Roborock E25 Power and Airflow


We tested its airflow and found that it was extremely powerful. In its max power mode, we measured 17 cfm of airflow, which is the same as the top of the line Roomba 980 and i7. It actually has four power settings, which is more than I have ever seen on a robot, and even the next step down from max power—the strong power setting—is pretty high at 15 cfm.


As far as the pickup tests, I was genuinely impressed. On carpet, it was excellent, picking up all the debris from fine debris to extra large debris. We found that while it did better on max power, the differences between med-high, medium-low, and low were all pretty minimal. In other words, it was uncommonly good on carpet on all its settings.


With hard floors, again, I was very impressed. Not only did it pick up all the debris in the tests, we found that it kicked around less debris than any Roomba we have tested, and they tend to be quite messy. The only issue we found was that in its lowest setting (what Roborock calls silent mode), it did struggle with fine debris on hard floors, though it did pick it up by the end of its run and did quite well with large debris and even pet hair in silent mode, but its silent mode just has too little airflow to be as effective on hard floors. But, on the plus side, all three of the other power settings proved to be more than enough power on hard floors.


Part of the reason it does so well with pickup is that it has a pretty advanced brushroll system which adjusts to the floor height. It’s a much higher quality brush design than you typically see with Robots in this price range. All that to say that some robot vacuums can get away with having less power if they have good cleaning mechanics, but the Roborock has a lot of power and really good mechanics. So, yeah, it’s really good at cleaning.


One super important factor is dust bin size. It’s so important with Robot vacuums as they can only clean as long as their dust bin isn’t full, and the Robotrock E25 has a very big dust bin at 640 ml cups. On that point, the dust bin was easy to remove and easy to empty. It also has a HEPA filter which attaches to the bin.


A few other positive things before we get to the negative stuff.  It has better than average edge cleaning. In fact, I can’t remember a robot doing as good with edge cleaning as the E25.


It’s really quiet. It was about 70 db in max mode on hard floor, which is significantly less than the Roomba 980 on max, and it goes way down from there. It’s probably one of the quietest robot vacuums I have tested.


It’s very gentle when it bumps into things. Roborock calls it “gentle hit,” and it did have a lighter touch than most.


It has a nice low profile at 3.6”—the same as most Roombas, but it does much better with climbing 90-degree obstacles, and it’s light years better than the Roombas in terms of not disturbing small throw rugs. Again, I would say its better than any robot I have tested yet in that regard.


One thing with robot vacuums I have come to expect is a certain amount of mess in the housing and around the brush after a lot of cleanings, but after all the tests we put it though, it really was remarkably clean, which suggests that it is more efficient than most when it comes to cleaning. Even the brush was fairly clean. Roborock does claim it’s an anti-tangle brush—the same brush is on the high end S5, so, maybe that is why.


Roborock E25 Battery Life


Its battery life is pretty decent considering its power. Roborock claims 100 minutes on low power and that’s true, but on max power it drops to about 51 minutes, the next step down (strong power) got a little over an hour at about 61 minutes. So, it’s not amazing, but it’s not bad either. Again, consider in the same test conditions the Roomba 980 only got 48 minutes with pretty much the exact same power output. I should also mention that I didn’t test the so-called standard power mode, but you can assume it would be between sixty-one minutes and one-hundred minutes.


The app is really good for what it does. You can schedule cleaning from anywhere with cell service. You get reports on the progress or alerts if there are problems. You can choose the power mode, start and stop cleanings, and it even develops a map after a few runs, though I couldn’t get this feature to work until I updated the software. It’s also compatible with smart devices like Amazon Alexa and Google assistant.


Ok, so, let’s move on to the negative stuff.


So, I didn’t talk about the mopping feature yet. The E25 comes with a mopping attachment that locks on to the bottom of the unit. You just fill it up with water, and it slowly saturates the mopping pad. The robot functions normally as a dry vacuum at the same time. It comes with extra pads and a special waterproof pad for the dock to use when mopping.


I, personally, have yet to test a robot mop hybrid that is very effective at mopping and the E25 was no different.


I tested it with some stains that have been on the studio floor for about a week, and after running a full cycle, it didn’t get the stains. It’s serviceable as a mop if you just want a surface cleaning, but it’s not going to take the place of a mop, but, again, I have yet to find a robot vacuum hybrid than can.


It doesn’t come with any barrier feature on the app or any other type of barriers like magnetic strips. This isn’t a deal breaker as most people don’t even use them, but it would be an issue if you had certain areas that you didn’t want the robot vacuum to go that you couldn’t block off by other means. It also means that you probably would not want to use the mopping feature if you have a mix of hard floors and carpet since the robot would just start mopping the carpet as well unless you were keeping an eye on it.


Like almost all robot vacuums, it struggles with black carpet. The drop sensors think it’s about to fall off a cliff, and, so, it just can’t clean black surfaces. But this is pretty much the same with all robot vacuums with cliff detection sensors.


So, despite those minor things the Roborock E25 was really impressive. The navigation blew me away by performing like a vacuum twice its price. It also punches above its weight class in cleaning ability on both hard floors and carpet and does so with significantly less mess than average. It has a ton of power, a huge dust bin, and good battery life, and its brush and other components seem well-built.


Also, because Roborock has become one of the best robot vacuum manufacturers in recent years, it’s not hard to find replacement parts or other consumables.
