Viomi

Viomi is Xiaomi's smart home subsidiary, giving them access to established supply chains and smart home integration. Their budget robot vacuums use LDS (Laser Distance Sensor) mapping instead of more expensive LiDAR, cutting costs while maintaining navigation. Auto dirt disposal and app control come standard on their entry-level models.

Viomi is strongest in Chinese and Asian markets where Xiaomi's ecosystem is well established. They're a solid pick if you own other Xiaomi smart home devices or live in a region where Viomi support and services are solid.
