REVIEW – Of all the gadgets I review, my wife prefers I review the ones that actually do something—like clean, for instance. She couldn’t care less about my audio fixation. Nope—as long as I review something that makes her life easier, she’s okay with the time I spend testing and writing. Just so you know, she approves of this review. But do we (more importantly—the Queen) approve of the new Roborock Dyad Wet and Dry Vacuum Cleaner to help keep our floors clean?

What is it?

The Dyad is Roborock’s newest—and only—wet/dry vacuum cleaner. It does what the product name implies. It mops and sucks up wet messes leaving the floor clean. DyadPower—what Roborock calls its battery/charger system—simply means it’s cordless.

The Dyad uses room-temperature tap water (or water mixed with Roborock’s floor cleaner solution) from its clean-water tank, wets three counter-rotating rollers, then sucks the wet mess into a dirty-water tank. The vacuum action leaves the floor dry (or slightly damp that quickly evaporates).

It has an LED screen that displays battery level, water tank levels, and different cleaning modes: Floor drying, Auto, and Max. The Dyad comes with a charging dock that doubles as a self-cleaning stand that helps keep the rollers clean after use. 

The Dyad also has voice alerts—more on that later in the review.

Design and features

Since my wife is a clean freak, she insists on keeping our floors spotless. She also insists on doing it herself, because I “don’t do as good of a job as she does” (her words—quite true). So that usually gets me off the hook. Sometimes I help vacuum and mop, but it’s rare.

Saturday is usually cleaning day and in the past, our tile floors (carpet is verboten in our house) were steam-cleaned after vacuuming. I was never a fan of the steam cleaner, as it pushed around an increasingly dirty mop/pad as you used it. So, when Roborock made the Dyad available for review, I jumped at it hoping to convince my wife that this might be a more sanitary floor-cleaning method.

After the Roborock Dyad arrived, we immediately ran into an issue: The machine kept verbally telling us that the clean-water tank was empty—when it had just been filled. Note that the Dyad will not work if the clean-water tank is empty—or even if the Dyad thinks it is.

Memo to Roborock: While the voice alerts can be handy, please lower the volume. It sounds like a science-fiction countdown to armageddon unless the pod-bay doors aren’t closed quickly enough. The good news is that the voice prompts can be turned off or the language can be changed if you want to hear loud prompts in Spanish or French (my wife’s favorite). 

When we realized we had a defective Dyad, I got on the phone with Roborock support and they walked me through some corrective steps—which did not fix the issue. The extremely nice and helpful support guy (kudos Roborock!) bumped the issue up to the next level and in a few days, Roborock sent out a replacement unit. We were later told that the first shipment of Dyad cleaners were pre-production units that had a circuit board issue which was fixed by the time production units shipped.

Once the replacement arrived, all was well. Let me re-phrase that: Once the replacement arrived, all was wonderfully well. The Roborock Dyad rocks.

Using the Dyad is simple enough. Out of the box, all you need to do is snap on the handle and then snap the charging dock/roller cleaner together. The Dyad will need to be fully charged before use.

Battery life is rated at 35 minutes in Auto mode. Max mode has a much shorter battery life. My suggestion is to use the Dyad in Auto mode only. 

Although not necessary, If there is a mess that requires Max mode, I suggest wiping up what you can with paper towels before using the Dyad. That way, the Dyad can have an easier time cleaning.

The Roborock Dyad vacuum will not stand upright on its own, although it comes with what can best be called a kick-stand. With the stand extended, the Dyad’s handle will not fall all the way to the floor sparing your back.

When on, you can select either the Auto or Max modes from the buttons on the handle. Auto mode self-adjusts as you clean. The LED screen has a dial that goes from blue to red indicating how much “dirt” the Dyad has encountered. Max mode is what it says—flat-out full power all the way. Again, I recommend avoiding Max.

As the Roborock Dyad vacuum cleans, two rows of rollers spin in opposite directions which pushes the mess up into the dirty-water tank while it vacuums. This method also cleans better since the rollers go over the same area in different directions as you clean. These rollers go to the edge, so you can clean right up to the baseboards. The cleaning head of the Dyad swivels making it easier to clean around table and chair legs and other obstacles. However, it will not lower itself flat to go far under furniture.

Pushing and pulling the Dyad requires minimal effort. The spinning rollers help it move in the direction you want it to go. However, when it’s turned off, its weight can make it difficult to move or carry.

Not only will the Dyad vacuum spills and other wet messes, but it can also vacuum up dry spills, such as snacks or dry dog food. Even so, I wouldn’t buy the Dyad for this reason. It’s easier to just get a broom and dust bin to sweep up dry spills than to drag out a vacuum cleaner—any vacuum cleaner. The Dyad shines with wet or wet/dry messes. 

If you have pets, you may want to vacuum the floor first with a regular vacuum cleaner. Roborock says that pet hair may clog the Dyad’s rollers. Getting the hair up first can save you some trouble.

Both the upper clean-water and lower dirty-water tanks can be easily removed for filling and emptying. Once done, They snap right back into place. The dirty water tank can be disassembled for easy cleaning. When done cleaning, just empty the tank in the sink or outside if you prefer.  

Roborock sells a cleaner fluid you can add to the Dyad, but I’ve never been a fan of applying any kind of floor cleaner as they can attract more dirt with residue they leave behind. Oddly, Roborock did not include a sample of their own cleaner in the box. Maybe that’s a hint?

Although the rollers are self-cleaned in the dock after use, they will still occasionally need to be removed for a more thorough cleaning. The self-cleaning mode allows more time between those hands-on cleanings.

What’s cool is that as you vacuum, the power of the Roborock Dyad practically dries the floor as you clean. Only in spots have I seen damp residue left after cleaning. And even that evaporates quickly. So, wood or laminate floors are safe when using the Dyad.

What I like

  • Cleans well
  • Dries the floor as it cleans
  • Easy to set up and use
  • Self-cleaning
  • Powerful

What I’d change

  • Ability to lower the volume of voice prompts without turning off

Final Thoughts

As I said earlier, the Roborock Dyad Wet and Dry Vacuum Cleaner is a welcome addition to our home. My wife appreciates how it cleans without spreading increasingly dirty water over the floor. We can actually feel the cleaner floor in bare feet after using, something we couldn’t feel after steam mopping. In fact, since using the Dyad, the steam mop has not been used—at all. My wife likes the Dyad as do I.

Now, if I could just get her to appreciate audio gear …
