On February 19, Coworth released the first sweeping robot DeEBOT T9 in the Year of the Ox. The core upgrade points of the new machine are obstacle avoidance and 3D map, stronger drag and sweep ability, and very sexy mobile fragrance and sterilization function.

The previous sweeping robots scratched their heads just to avoid obstacles and clean, but to the generation of Dibao T9, they have added 3D house type maps, and even subdivision functions such as aromatherapy and sterilization, and started to run in the direction of integration.

Every time I evaluate this product, I am very happy because the product is very strong and has no psychological burden.

Appearance

Coworth distinguishes channels by product suffixes. The rules are the same as T8. T9 is called T9 Power on JD and T9 Max on Tmall

Compared with the previous generation, the side of the T9 has also become a pure white design. The debut of this ID is the peak. The gold and white top cover, plus the full white body, is still very good.

The weight of nearly 6 kg is very important, and the nozzle and mold opening line of parts are well controlled.

The dust will be more conspicuous on the black body, so the sweeping robot is recommended to buy a white one. In addition to being easier to handle, it is not easy to step on the black one at night (don't ask me why I know).

Obstacle avoidance and map building: it has been the ancestral strength

The obstacle avoidance and planning systems that Covos is proud of have been upgraded to version 2.0 on T9, corresponding to TrueDetect 3D 2.0 and TrueMapping 2.0 respectively.

The structured light emitted by T9 can be captured at a specific angle

The previous generation of obstacle avoidance system has been a 1mm level dToF. The core upgrade of this generation of TrueDetect 3D 2.0 is structured light technology and 3D imaging algorithm. In addition to the speed and accuracy of mapping, dToF is not affected by sunlight, strong light and dark light scenes, and can build maps at any time in 24 hours.

The TrueMapping 2.0 global planning system does not speak of martial virtues. In the past, the sweeping robot scanned the flat house type map, while the Kvos T9 scanned the map with a 3D three-dimensional house type map. The mass production version can directly scan a 3D map similar to the model, and then you can carefully review the layout of Shenzhen Bay No. 1.

T9 can sense thin and light obstacles such as mobile phones

A thicker red envelope can also be felt

When encountering "dangerous goods" such as data lines, the obstacle avoidance distance will be extended

For non threatening table legs and potted plants, T9 will go crazy at the extreme distance

Because of the introduction of strategic obstacle avoidance, you will find that T9 will use different obstacle avoidance schemes according to different types of obstacles. Safety barriers such as shoes, table and chair feet are all 3cm around by default, while the obstacle avoidance distance of "dangerous goods" such as wires, curtain tassels that can roll up the wire clamp will be increased to 5cm. wow，awesome。

After the sweeping robot does not eat socks, data lines, push shoes and toys on the ground, and will not "change the terrain", it is extremely "insensitive" to work. It is really hard for you to recall whether you have turned on the regular cleaning function.

After the app UI is revised this year, in addition to the existing multi-layer maps (dedicated to loft houses and duplex villas, but we don't need 400 square floors), customized split areas, independent map leak filling, and breakpoint scanning, we can also select different cleaning sequences and multiple cleaning modes for different areas, with many subdivision functions.

Unexpected fragrance and disinfection function

Fragrance and disinfection are both functions that will make you pat your head and say "why didn't you think of it at that time".

The mop accompanying T9 has become a non cleaning wet mop with sterilization function. It is similar to the package of wet paper towels. There are 10 pieces in a package. The disinfectant inside is a little lavender.

In the test report, 99.9% of the daily pathogenic bacteria, such as Escherichia coli and Staphylococcus aureus, as well as the "odor causing mildew" soil mold, are killed. It is suitable for children to crawl around or families with high requirements for cleanliness.

The material of these disposable mops is interesting. The substrate is soft mops. The twill road is hard, and the water absorption of the front and back is different. The actual measurement shows that it has a good removal effect on old water stains, even stubborn stains such as transparent glue stains.

For one thing, this is the best disposable mop that Benji has ever seen. It is estimated that there will be no similar high imitation accessories (wealth password of consumables) for a while.

But if I want to say what is the most exciting new function on the Kovos T9, I will not hesitate to answer: Air Freshener mobile fragrance. This is the first and only sweeping robot with fragrance function on the earth.

T9 has more fragrance modules called deodorant partners. This "external backpack" has air ducts and fragrance capsules (the official logo has a life span of 60 days), and it, too, is electrically controlled (Teacher Luo: to win or lose is to be serious...).

The fragrance switch can be controlled in the APP. When the machine is idle, the fragrance will be locked automatically to avoid the loss of fragrance. With the partition function of app, if you like, you can even put different fragrances in different rooms every day. Life is so exquisite.

The first sweeping robot fragrance system in the universe provides three kinds of natural fragrance options: "blue wind chime, green melon and oak moss, bergamot and lavender". The "Blue Campanula" flavor is randomly attached to T9. The actual flavor output is not strong, and the faint feeling is more comfortable than the concentrated flavor on the softener. It is the type of "more durable, plain and faint is true".

When T9 generates the house type map, it will also generate the WiFi strength map, so it can easily detect where the signal is abnormal

In practical use, more fragrance should be put into pet areas, kitchens and other areas with greater flavor. When sweeping and mopping the floor, we should remove the smell of mildew, odor, and the smell of the master of the excrement shovel. It's really "colorful", I like it。

Double suction+bass drag

In terms of the most basic sweeping and mopping capabilities of the sweeping robot, T9 takes the most simple and violent route of suction improvement. 19000 fan plus new volute and fan blade materials, the suction of the former generation is 1500Pa, directly doubled to 3000Pa, Surprise！

Iron screw of computer case (closing barrier avoidance, maximum suction)

The screwdriver head, even the clamping needle, can be forced to suck up (closing to avoid obstacles, maximum suction)

For reference, 1500Pa can suck soybeans. 3000Pa is the level of steel ball suction. It suddenly became clear why T9 was upgraded along with obstacle avoidance distance and object recognition ability.

Such suction can cope with soil without pressure

Of course, the sound of super gear is also fierce. But anyway, there are many gears provided. One thing is that I can not use them, but they can't do without them. By the way, the Covance T9 can be used with Auto Empty automatic dust collector, which is a 2.5L monthly throwing dust bag. Of course, to become stronger, you have to pay more.

In terms of sweeping, the OZMO Pro high-frequency vibration wiping system also has a 2.0 suffix. The first generation solved the problem of stubborn stains, while this generation mainly focuses on mute and life optimization. It is claimed that the imported motor and new sports structure have been replaced, the noise intensity of the official logo has been halved, and the service life has doubled. The measured nearby noise is below 69 decibels, which is not even loud enough for T9 voice prompt.

Sticky old yogurt

Strong to granular black tea

The new movement structure is still a simulation of human hands, which uses a giant motor to control the rag support to repeatedly wipe the ground with a high frequency of up to 480 times per minute. Sticky yoghurt and granular black tea can be "machine passed without leaving a mark", and they can be cleaned again and again without much pressure.

The app now has the function of no dragging area, which will not wet the water tank in the area set not to be washed, saving water and reducing the frequency of water change, and the carpet will not be wet by the wrong hand.

summary

The previous sweeping robots were "pie huskies" that hit everywhere by inertial navigation. Their sweeping effect was certainly not as good as that of cleaning aunts who spent dozens of dollars an hour. However, the sweeping robots were better than those who could sweep every day. The cleaning effect of a small number of times was better than that of aunt's surprise cleaning.

T8 of last year has been very strong. Obstacle avoidance, navigation and sweeping are very balanced. This year's The Covance T9 has a 3000 Pa suction that can absorb steel balls, a forced drag mode that reduces noise and improves life, a dToF and 3D environment imaging capability that is not affected by light, and also launched the first fragrance system and sterilization wet mop. As a normal replacement, the increase is a matter of conscience, and it seems that Coworth still has some spare power.

At this time of year, like many people, I will say goodbye to the past. Thank you for your company for 300 days and nights. I will become a traitor in your eyes. Sorry, I have to change T9.
