In March of this year, Roborock released its annual new Roborock T7 sweeping robot. And only two months later, Roborock launched an upgraded version of the T7 – Roborock T7 Pro. The price tags are 2899 yuan ($430) and 3899 yuan ($578). The gap is quite big. So we wonder what is the difference between the two sweeping robots.
The first is the appearance. The main body of the Roborock T7 is white, supplemented by a small area of orange as an embellishment. The Roborock T7 Pro is black, with a ceramic-like luster on the surface of the body. It highlights the texture of the high-end flagship. Stone also named it the ‘exploration version’.
The T7 Pro uses binocular obstacle avoidance technology. So the front of the fuselage has two large eyes with 5MP resolution. This is also the biggest difference in appearance from the T7. The two sweeping robots come an LDS laser sensor, a 297ml detachable electronically controlled water tank at the rear, and a 2500Pa suction power.
Cutting-edge technology: binocular obstacle avoidance
As the obstacle avoidance system of mainstream sweeping robots, the laser sensor realizes obstacle avoidance and escape by scanning and composing the surrounding environment. The Roborock T7 also uses this obstacle avoidance system; for the complex environment where a large number of objects on the ground at home are not fixed, the Roborock T7 Pro adds dual cameras in addition to the laser sensor to realize binocular obstacle avoidance. So the sweeping robot not only has ‘feel’ but also ‘vision’.
Thus, it not only can get the length and width, but also can judge the distance of the object through dual cameras, and really feel the three-dimensional picture. Obstacle avoidance is achieved by identifying and ranging objects in the home. This greatly improves the effect of obstacle avoidance. At the same time, with infrared fill light, it can ensure the accuracy of obstacle avoidance even in dark environments. With the camera on the fuselage, it can also remotely view the home status. This vacuum cleaner has passed the German Rheinland certification to ensure privacy.
In general, for those users, whose home layout is not complicated, there are no pets or children, and users who have relatively fixed obstacles can get a good experience by starting with the Roborock T7. For users who like cutting-edge technology and there are always unfixed obstacles in their homes, it is more appropriate to start with the Roborock T7 Pro, which comes with more powerful obstacle avoidance function.
