Roborock S7 robot vacuum review: Mopping up at sonic speed

Roborock has had an amazing ride over the years. Once an unknown player in the robot vacuum space, the company is in contention against some heavyweights like the iRobot, Shark, and Ecovacs, thanks to its diverse and outstanding performance models. Even more impressive is how the company was mired in controversy among the giants in such a short period of time.

Its latest model, the Roborock S7, has all the same basic elements that made its previous bots so successful, such as the one-for-one vacuum and mop combo, but its distinguishing feature over the competition is the new sonic vibration technology it employs with mopping. does. . If this new implementation really works, getting stuck on stains may soon be a thing of the past—not to mention the auto-empty dock that’s releasing later this year.

A familiar bot that cleans efficiently

The Roborock S7 doesn’t look much different from its siblings. There are a few subtle changes, like “breathing” LED lights that fade in and out, a more compact water container, and most importantly, a new all-rubber underside brush. Aesthetically, it doesn’t deviate from the previous designs we’ve seen from Roborock’s bots. The same distinctive features are present here, such as its raised lidar sensor array, rubberized side-sweeping brush and all-plastic construction.

In terms of cleaning, the Roborock S7 cleans efficiently thanks to its lidar-based navigation. It maps rooms accurately and does a good job avoiding most obstacles. The occasional cable wire on the floor may propel it uphill, but it’s capable of navigating challenging rooms by trying to clean in straight lines. Its side-sweeping brush does a good job of funneling debris toward the underside’s all-rubber brush. However, after a few cleaning sessions, I found that the hair was tangled and tangled in the middle of the brush.

Despite this, it manages to suck up some annoying bits of litter all over my apartment. The rugs are handled decently, as it picks up most surface stuff with its 2500Pa suction power, but it doesn’t come close to scooping up the tough, embedded pieces that my cordless vacuum is able to collect.

Is sonic-mopping technology legit?

The biggest feature of the Roborock S7 is its new sonic-mopping technology. All of Roborock’s older vacuums use the wipe-pull method. Frankly, I’m satisfied with it, but it doesn’t necessarily disinfect surfaces—something that very few bots can do.

It requires fewer passes to remove stains on solid surfaces.

The S7’s sonic-mopping technology comes with a new brushing attachment and a more substantial-feeling microfiber mopping pad. What happens here is that the mopping pad vibrates at a rate of up to 3,000 times per minute. It’s different, yet effective because the result is that it requires fewer passes to remove stains on concrete surfaces—like small drops of dried coffee on tiles. Now, it doesn’t remove those tough, dark stains like streaks that can be left on sneaker tiles, which a good old mop can accomplish with just enough pressure and scrubbing. But hey, at least it cleans floors just as efficiently as it vacuums. Time is money, so I’m impressed with how quickly it gets the job done, though I’d still like to see a way to disinfect surfaces.

Even better, the S7 will retract the mopping pad when it goes over humps, dividers, and carpet, then lowers it back down to apply the pressure needed for its sonic mopping. The other 2-in-1 combo requires you to remove the mopping pad to vacuum the carpets.

you barely heard it cleaning

With two people working from home and on constant conference calls throughout the day, I’m very impressed with how quiet the Roborock S7 is. It’s most noisy when it gets on carpets, but it’s almost imperceptible as it cleans hardwood floors and tiles. There’s a slight rumble when it’s mopped, but it’s low enough to overwhelm with some music playing in the background.

Other than that, the Roborock S7 is a capable robot vacuum because it’s packed with all the modern features I’ve been craving. These include support for voice assistants like Google Assistant and Amazon Alexa, the ability to set up virtual boundaries/no-go areas, and the ability to clean specific rooms. All this makes the Roborock S7 a well-rounded bot that can clean quietly and effectively while at home.

our take

There’s nothing the Roborock S7 can’t handle. It cleans well, doesn’t waste time, and its new mopping system is a small but effective step. It’s not a game changer in the world of mopping, but the changes make it more efficient in the process.

The only downside to this otherwise spot-on robot vacuum is its price. At $649, it’s near the top of Roborock’s lineup—only surpassed by the camera-toting Roborock S6 MaxV. It’s a tough sell because I prefer the added functionality of the S6 MaxV’s integrated camera for intelligent obstacle avoidance and livestreaming.

How long will it last?

Even with the all-plastic construction, there’s some serious heft with the S7. The only concern I have is the plastic piece on the mopping pad attachment that allows it to vibrate back and forth. It seems to be on the delicate side, especially when removing the pad from the Velcro attachment. Nevertheless, a . is 1 year limited warranty.

Is there a better option?

Yes, the aforementioned Roborock S6 MaxV doesn’t get too far in price – making it a compelling choice because of the advantages of its integrated camera. It cleans just as effectively, whether vacuuming and mopping.

should you buy it?

Yes, simply because some people are not yet comfortable with the idea of ​​a vacuum rotating with a camera. The Roborock S7 is essentially the S6 MaxV without the camera, but with a better mopping system.
