HomeTech Review: Roborock Dyad Air Wet Dry Vacuum Cleaner

Most home vacuum cleaners are expert at cleaning up dry dust and dirt. The Roborock Dyad Air comes in useful when you have a wet mess on the floor – a cracked egg, spilt cereals with milk, overturned bowl of noodles in soup etc.

Christmas present for the wife. No more stress when the egg drops onto the floor or the kids spill soup noodle on the floor. Roborock Dyad Air wet dry vacuum cleaner.

For regular vacuuming and mopping of the floor of the apartment, I depend on a robot vacuum which is able to accomplish the job well and without complaining – regardless of how frequently or how many iterations I put the robot through its paces.

Occasionally, the wife drops an egg on the kitchen floor, or the kids spills some cereals with milk, or I spill some noodles with oily soup on the floor.

That’s when we have to roll up our sleeves, get on all fours and clean up the mess manually.

You can’t use a dry vacuum on the wet mess because you don’t want the vacuum to suck up the wet egg white and yolk into the dust bag and goo up the parts between the vacuum head and the dust bag, and have food remnants rotting away inside the dry vacuum.

And you can’t mop up manually until after the solid debris – the shells, cereals, noodles – have been picked up and removed.

That’s why I got my wife the Dyad Air wet dry vacuum.


Technically the Dyad Air is just a wet vacuum/mop – it wets the roller mop (and therefore the floor surface) with clean water (you can add a mild Roborock detergent) and sucks up the entire mess – solid debris and wet spills – into the dirty water tank of the Dyad Air.

After each use, you return the Dyad Air back to its plugged in dock which keeps it constantly charged – and cleans the roller mop AND dries it afterwards.

The self-cleaning supposedly cleans away up to 99% of the dirt in the roller head while the drying (over 2-6 hours depending on your settings in the app) prevents foul smells and mould from a wet mop in our humid climate.

I find the self cleaning pretty thorough because visual inspection shows the roller mop as good/clean as new even after cleaning up some very evil wet messes like noodles in oily kimchi soup.

The self-drying is also very silent and effective.

Operating the Dyad Air

At 4.1kg, I would consider the Dyad Air as lighter than those I have tried, but I would limit the lifting to removing and putting back the vacuum from/to the dock.

Once it is off the dock, I’d just just roll it to where the wet mess is.

While cleaning, moving the Dyad Air forward is quite effortless, because the turning of the roller actually helps the vacuum move forward when switched on – a bit like when an automatic car’s gear is engaged when stationary.

Pulling back the vacuum doesn’t really take much effort either because the weight of the cleaner is supported by the floor.

So for cleaning a localised mess, I would do it in a forwards-and-backwards pattern; whereas for mopping a bigger area, I would go in large zig-zag patterns from one edge of the area/room to the other before making a u-turn – to clean the large area with most forward movement of the Dyad Air.

Need to catch a breath?

You can leave the Dyad Air standing upright on its own, simply tilt the handle forward to lock the roller head – this is the same position as when it is charging in the dock.

To unlock the roller head, simply step on the head and tilt the handle back.

There are four cleaning modes on the Dyad Air – Auto, Max, Eco, Floor Drying modes.

The eco mode uses lower suction power (to conserve battery), roller speed, and amount of clean water and is suitable for a quick mop of a room.

The Dyad Air can be added to the Roborock app.

The battery is rated for 50 minutes of usage on a full charge, which translates to a floor area of 360 (3,875 sqft) square metres.

For me that just about covers my entire apartment – I still have 30% battery left after a quick clean.

The max mode uses maximum suction (which uses up the battery faster), roller speed and water for the really mean wet and oily messes.

Most of the time, you can just leave the Dyad Air on Auto mode.

It uses a DirTect Smart Sensor to detect how messy the floor surface is and adaptive adjusts real-time the level of suction, roller speed, and amount of water used to clean up.

It even tells you with an arrow on the LED display the direction where the most severe mess is so you can move the Dyad Air there.

The fourth mode is Floor-Drying mode – you can use that to suck and mop up spilt clean water on the floor, or even dry up the wet floor of a freshly washed bathroom (but not a flooded kitchen floor).

I like the splash guard on the roller head which can be toggled in two height settings to determine the size of debris to let in to be sucked up by the vacuum.

Setting Up

Setting up the Dyad Air is easy – out of the box, it takes only six steps to assemble the Dyad Air and start charging it.

  1. Stick the handle into the main body of the vacuum cleaner (the clean and dirty water tanks with filter come pre-installed in the box).
  2. Press the charging dock tray onto the dock body by aligning them and pressing the former downwards.
  3. Connect one end of the power adaptor to the dock.
  4. Plug in the other end of the power cable to the wall socket.
  5. Switch on the wall socket.
  6. Place the Dyad Air onto the charging dock.

To start cleaning with the Dyad Air, simply fill up the clean water tank, switch on the vacuum cleaner, lift it off the dock and you’re good to go.

The clean water tank has a 900ml capacity while the dirty water tank has a 770ml capacity.

There are 3 press buttons on the handle of the Dyad Air.

  1. Self-clean button
  2. Mode button
  3. Power button

The Mode button cycles through the four cleaning modes which is indicated on the LED display on Dyad Air – together with other information such as battery level.

The Power button begins/pauses cleaning.

My Take

The Dyad Air is a useful addition to the cleaning arsenal for the home – enabling fuss-free cleaning of the dreaded wet mess.

It performed very well and cleaned thoroughly – both the floor and the mop itself afterwards.

It complements the robot vacuum and handheld vacuum cleaner to complete the cleaning toolbox and makes a great gift to the home-maker.

Self cleaning is done when the Dyad Air is back on the dock – a single press initiates standard self-cleaning while holding the button down for two seconds activates the DEEP self-cleaning mode.

The Dyad Air can be added to the Roborock app enabling a few additional settings.

These include automatically initiating self-cleaning upon returning the Dyad Air to the dock; automatically resuming operation upon unlocking the cleaning head and duration for drying the roller mop; as well as the volume and language for the voice alerts.

Incidentally, the verbose voice alerts from the Dyad Air are really easy to understand, instead of the usual cryptic error codes and curt blurbs on most appliances.


Additional settings for the Dyad Air are available in the Roborock app.

For a start, the RevoBrush Self-Cleaning & Drying System already takes the chore out of the other half of cleaning up a wet mess – cleaning the mop used to clean up the mess.

My friend has a yard area where the old chute spews dead roaches every time he opens and closes the chute door.

She dreads cleaning up that area.

Now she’s getting a Dyad Air just to enable her to clean up those dead roach carcasses and other debris without getting her hands dirty at all – both during cleaning up and cleaning up the broom/mop.

All she’s going to need do is to empty the dirty water tank and rinse out the tank.

The Dyad Air comes with a brush to help clean the roller mop, the roller holder, dirty water pipes etc.

These routine maintenance tasks are needed only once a month and are easy and not tedious.

The dock tray can be detached to rinse under a running tap, while the roller mop can also be easily detached to cut and remove any entangled hair.

    I like that it can dry the bathroom floor. I’m so worried that my aged parents will slip and fall when the bathroom floor is wet, especially after the helper washes the bathrooms.

    The floor-drying mode should come in useful, don’t need to use the mop which needs to be rinsed and dried after each use.
