Convenience of use
The Roborock Dyad Pro looks like two drops of water to its predecessor. Lighter by 200 g, the floor cleaner weighs 4.8 kg and weighs on the arm at the end of cleaning. The Kärcher FC3 wireless is much more pleasant in the long run with its featherweight 2.4 kg.
But to defend the Roborock, the latter has two water tanks, unlike its German competitor. The first can hold up to 900 ml of clean water and the second is able to collect 770 ml of dirty water, as well as vacuumed debris.
The clean water tank is easy to fill.
Because yes, the Dyad Pro can wash wet residue as well as vacuum up dirt and dust. Broken egg on the ground, ketchup, coffee or cat’s croquettes… everything should be fine. This debris is trapped by a sieve to prevent it from settling at the bottom of the dirty water tank. In fact, it is otherwise. The holes in the sieve are so wide that they let most of the dirt through, which then gets immersed in the water — which isn’t appetizing. Most competitors have the same problem, like the Proscenic WashVac F20.
The HEPA filter located on top of the dirty water tank and the sieve, with relative efficiency.
To clean and vacuum the floor, the Roborock retains its three rollers, already present on the first version. They also rotate in the opposite direction to better trap dirt strewn on the ground. And for more thoroughness, the washing head has been redesigned. Called “edge-to-edge”, it runs along baseboards and furniture to within 1 mm. It is still very imposing and does not facilitate travel. Indeed, if it is motorized and advances without difficulty, changes of trajectory and reverse gears are not always easy. And that’s not counting the passage under the furniture, which is almost impossible.
On the top of the head, a capsule has been added compared to the previous model. It is designed to contain, as an option, a cleaning solution to better clean the floor. According to Roborock, one capsule would be enough for 600 min of washing – which we will not test in our laboratory. And it is the Dyad which automatically distributes the quantity of cleaning product.
The user has the choice between four different modes: eco, max, auto and drying. This last mode makes it possible to vacuum the wet substances present on the ground without the broom releasing water. Once Roborock has switched to automatic mode, it is able to adapt its suction power – up to 17,000 Pa – and its water flow depending on the dirt detected. On the screen, an arc of a circle going from blue to red makes it possible to visualize the level of dust.
A screen is actually positioned on top of the water tank. It indicates the battery level of the Dyad Pro, the active scrub mode and possible errors encountered by the mop, such as a full or empty tank. As such, it is reminiscent of that of the Dreame H12.
On the handle are the only three controls of the floor cleaner. The first turns the device on and off, the second changes the cleaning modes, while the third initiates the roller self-cleaning procedure. The base of the Roborock Dyad Pro also has a novelty compared to the first version: it is now able to dry the three rollers after cleaning them.
Another small novelty is finally to be noted, and it is very important: the possibility of putting the Dyad Pro in the parking position. So there’s no need to look for a secure place to set up your broom for a break, it stands up on its own. A welcome improvement and already implemented by several competitors.

Interview
As said before, the Dyad Pro is able to clean its rollers on its own once positioned on its base, thanks to the alternating friction of these. The station also takes care of drying them, in order to avoid the development of mold and bad smells. We still recommend washing them regularly by hand and drying them outside the washing head.
The rollers are removed by turning the red knob.
As for the maintenance of the dirty water tank, it is not the most pleasant. Debris and dust are mixed with dirty water. If a sieve is provided by Roborock, it is far from effective: it lets all the residues pass to the bottom of the tank.
Finally, a HEPA filter sits on top of the dirty water tank and has the task of retaining the finest dust particles.

Lavage
Like its competitors, we test the Dyad Pro without a cleaning solution. Either way, the Roborock’s three rollers and their spacing bode well for good washing performance.
To find out for sure, we deliberately spread soda, oil, lipstick and carbon black on the floor. After overnight drying, the floor cleaner comes into play.
It only took him two round trips to completely eliminate the soda and oil; this is a very good result. By comparison, other devices quickly remove either substance, but rarely both. The Tineco Floor One S5, for example, got through the oil in one round trip, but asked for four against the soda.
The roborock once again achieves good results in cleaning carbon black. More tenacious than the first two substances, this one is removed in four round trips, when the Vileda Looper asks for an additional one.
Finally, it thickens with lipstick, still present after 20 passages. In his defense, only three devices tested by us managed to completely clean the floor, including the Kobold Cordless Multi-Function Vacuum Cleaner.

Conclusion

How does grading work?
The Dyad Pro leaves nothing to chance. To wash the floor, its three rollers move tirelessly and achieve very good results. Its two large capacity water tanks make cleaning sessions easier and avoid soggy soil by sucking up the surplus. And we salute the parking position of the broom, new in this Pro version. However, the Dyad’s weight and upkeep remain Roborock’s pet peeve, as does its hulking wash head.
