Suction power: Generally, a suction power of 1500-2000pa can meet most usage scenarios. Higher suction power may result in better cleaning effects, but there is no need to overly pursue high suction power because it is not the only factor determining the cleaning effect.

App functions: Perfect app functions are crucial for the later usage experience. For example, you can use the app to plan virtual walls to prevent the robot from entering areas that you don't want to clean; schedule the working time of the robot; set working prompts, remote control modes, etc. You can also view the working status of the robot, cleaning records and other information.

Hair anti-entanglement: Hair entangling the roller brush will affect the cleaning performance of the robot, leading to decreased suction power and lower cleaning efficiency. Seriously, it may even damage the robot. Pay attention to the design and optimization of the sweeping robot in preventing hair entanglement on the roller brush.

Noise: If the sweeping robot is mainly used when no one is at home, then the noise index may not be a key factor; but if the usage time is more flexible, you can pay attention to the noise level of the product.
