We’ve noticed that even finer dust and dirt particles don’t stand a chance, thanks to its strong airflow combined with smart navigation that ensures every corner is covered.
The advanced LiDAR navigation and obstacle avoidance system mean it can glide around furniture and tricky spots without getting stuck, which is crucial for maintaining consistent cleaning in homes with pets.
