The technological progress of sweeping robots is not as fast as other electronic products. Although the new model adds new features, the old model is still competitive. The ECOVACS Deebot T9 AIVI, released at the end of October 2021, is still selling well thanks to the AeroForce rubber double brush, AIVI 2.0 camera obstacle detection and OZMO Pro 2.0 wipe capability.
Special roller technology
At the bottom we can see that there are two rotating edge brushes. Secondly, the AeroForce rubber double brush will attract attention. This is made up of two rubber brushes that rotate in opposite directions for better pickup of dirt. For pet owners, rubber brushes should be a big advantage, because they will not tangle the hair, which can avoid tedious cleaning in the later stages.

Various sensor navigation
Optimized navigation with lidar and obstacle detection enables the ECOVACS DEEBOT T9 AIVI to accurately provide 3D mapping. The camera on the front detects obstacles, even flat objects, and can detect and by pass them. After cleaning, you can also see obstacles in the map. It also doesn't fall off the stairs because there are sensors at the bottom for obstacle detection and also to prevent falls. Ecovacs offers a variety of sensor additions that will still be worth a look in 2022.
Good suction effect
The maximum suction force of the T9 AIVI is 3000 Pa, which is 100% higher than the T8 AIVI. Thanks to the suction power of 3000 Pa, it sucks away large crumbs that fall to the ground very well. Even in the first stage of four different strengths of suction, sucking away pet hair, dust or even cat litter is not a problem. It also offers automatic carpet detection, which automatically increases the suction level as soon as it leaves the hard floor onto the carpet. The bad thing is that the dust collector has a capacity of only 300ml.
Carpets can be detected automatically
On the T9 AIVI, there is Ozmo Pro wiping technology. Roborock and Xiaomi also use the technology. It can lift the wiper unit, so it is also possible to drive on the carpet. Unfortunately, its water tank is only 180ml.
The 3D map is available after a secondary auto-sweep. You can see the exact floor plan of the home, it also identifies some of the furniture. If you don't recognize everything correctly, you can also edit to add new furniture. This is mainly used for special cleaning of specific furniture, such as under a sofa.
The ECOVACS DEEBOT T9 AIVI is arguably one of the best vacuum robots on the market today. Whether it is vacuuming or wiping, its cleaning effect is better. In terms of price, it's about half what it was a year ago. However, the capacity of the dust collection tank and water tank is a bit small, enough to buy a suction station can solve the dust box problem. If you think it's right for you in every way, you can choose to buy it.
