In order to achieve this, both sweepers and floor scrubber products have already developed self-cleaning functions, so as to reduce user operations as much as possible. However, as a cleaning appliance, "hair entanglement" is still a hurdle that the industry can't cross.
For manufacturers, the more pain points there are, the more technological innovation is needed. In view of the current difficulty in the floor scrubber industry, Dreame H20 Ultra adopts a new "cutting tooth blade", which is known as turning passive into active and solving the problem of hair entanglement from the source.
It just so happens that in the recent pet shedding season, pet owners will come to see if it can really be cleaned without manual cleaning and achieve zero hair entanglement with a roller brush!
What is "Active Multi-Wrap Protection"?
The reason why hair entanglement has become the biggest pain point of roller brush cleaning is mainly because the current industry's anti-tangle hair solution always requires the use of bird knives to manually cut hair. In this process, the roller brush may also be disassembled, and dirty hands are inevitable, and if you do not clean it manually in time, it will also affect the cleaning effect, which can be said to affect the use experience very much.
After removing the cover, you can see that the H20 Ultra has a large 61mm diameter roller brush, which can prevent hair entanglement for not too long hair, and there is also a comb tooth scraper close to the position of the roller brush, which can also intercept and comb long hair during the vacuuming process.
The internal scraping position is a major improvement of the Dreame H20 Ultra rotary version, that is, the back of this constant pressure comb structure is equipped with the first Swiss PPA cutting tooth blade pioneered by Dreame, with a total of 85 dense comb teeth, and the blade and the roller brush form a 60° angle to hook the hair wrapped around the roller brush and cut it directly.
The severed hair is forcefully retracted through its wing ring suction duct, and then the suction force of 18,000Pa can easily suck the hair into the sewage tank. During cleaning, the roller brush also has the function of forward and reverse, repeatedly rubbing the loose and remaining hair, and finally all the hair is cleaned.
This is also a complete set of active multiple anti-tangle systems coordinated by the "combing, cutting, suction, and washing" of the Dreame H20 Ultra Rotary Front.
To test how effective the system is. I collected my dog's scattered hair, which should be a common sight for pet owners. In fact, because the floor scrubber is wet mopping, my family is a long-haired dog, and the dog hair is very fine and soft, it is more difficult to clean up after wetting, I still have some doubts before the test whether it can really 0 tangled hair.

In the test, it can be seen that in terms of suction, the Dreame H20 Ultra Spinner Edition is completely fine, and the tangled hairs are easily sucked away. The highlight was the cleaning of the roller brush at the back, and after a clean-up, no hair residue on the roller brush was found. I repeated the same test three more times and didn't find a single hair on the brush. The Dreame H20 Ultra may really be a lifesaver for pet families and shedding stars.

Lying flat does not affect the ability to clean
For pet families, it is not enough to just roll the brush and wrap the hair, because the pet's hair will be taken to all corners during the shedding season, such as the bottom of the bed, the bottom of the table, the bottom of the sofa, etc.
In order to solve this pain point, Dreame H20 Ultra Xuanfeng Edition supports 180° flat lying function, as the name suggests, it can make the main engine inclination angle reach 180° to completely lie flat on the ground, generally about 14cm high under the bed, the bottom of the cabinet, etc. can be easily entered.
In addition, the built-in 4400 rpm perpetual water-gas separation motor in the Dreame H20 Ultra Rotary Front Edition sewage tank can not reduce the suction power when lying flat, and still maintain a large suction power of 18000Pa.
In use, when lying completely flat, there will not be a drop of water leaking out of the sewage tank and the clean water tank. The sidewall water tank of Dreame H20 Ultra adopts a water-locking design, and the high-speed motor separates water vapor to prevent backflow and better protect the motor. The fuselage is also equipped with universal wheels, which can also flexibly twist and move left and right in some places with small angles.
In addition, Dreame applies servo hub motors to floor scrubbers, and the booster wheels of the H20 Ultra rotary front version are equipped with intelligent algorithms such as dual motors + dual chips, which can identify the movement trend at a frequency of 500 times per second and judge the size of the booster implementation, which includes direction, steering, and speed.
I pushed the Dreame H20 Ultra to turn around in the corners of the table and the legs of the stool, pushing and pulling back and forth, and the welt operation, etc., almost as light as when I was moving in a straight line, so that I could do complete house cleaning efficiently without hand soreness. It is also very practical for users with high daily use frequency, large households, or heavy kitchen oil stains and need to be dragged back repeatedly.
The details are full and the experience is enhanced
In fact, the fast-rolling roller brush wet mopping, coupled with the large suction motor, the cleaning power is basically not a problem that mainstream floor scrubbers are worried about, but the self-cleaning power is more concerned. When you put the Dreame H20 Ultra Spiral Edition back on the cleaning base station, you can find that the roller brush and the base fit very tightly, which brings the advantage that there is more negative pressure when cleaning, and there is no splash and omission, ensuring the cleanliness of the base.
There is also a long metal sheet in the base station, which is the PTC heating element, and the Dreame H20 Ultra Rotary Edge Edition has upgraded the PTC with a larger area and higher temperature to heat the water to 100°C more quickly. Boiling water washing roller brush can better dissolve oil stains and improve the cleaning effect of roller brush. It also offers a dual-mode option for deep washing at 100°C and daily washing at 75°C.
What's more worth mentioning is that Dreame pioneered the self-cleaning of boiling water, and the sterilization effect is also the first in the industry to reach a sterilization rate of 99.9999%.
I used the Dreame H20 Ultra to clean the dark soy sauce on the floor with freeze-dried coffee powder, and the mixed wet and dry stains were completely stuck to the roller brush, and then used 100°C boiling water to deep clean it to see how effective it was.

After cleaning, remove the brush cover to see that it is still steaming, and when it cools, remove the brush and take a closer look, the dark black soy sauce has been cleaned. And after deep boiling and hot air drying, the roller brush is not only dry to the touch, but also fluffy, so as to ensure a long enough service life.
The hot air drying function of the base is similar to that of the tumble dryer, which is first centrifugal dehydration at high speed and then hot air drying. The Dreame H20 Ultra also performs very well in terms of drying noise, even when the room itself is very quiet, it does not give people a very disturbed feeling. It is much quieter than other 5-minute drying on the market.
At the same time, its hydrogen peroxide electrolyzed water sterilization technology can automatically generate hydrogen peroxide solution from tap water to achieve better inhibition of bacteria and odor removal.
All in all, the Dreame H20 Ultra has not changed much in terms of form, but it has improved a lot in terms of cleaning experience. In addition to the active multi-tangle anti-tangle hair, it also has several detailed functional improvements such as 180° flat laying, 100°C boiling water washing roller brush, sterilization, and low noise.
These functional improvements have really solved the pain points of users, and the upgrade of self-cleaning ability and easy maintenance has also greatly improved the practicability of floor scrubber products. In addition, the H20 series itself is a product series with a very high quality and price ratio of Dreame, this time the upgrade of the Dreame H20 Ultra Rotary Front Edition can be said to have submitted a full score for users, the overall performance is improved, and the user experience is better.
