How to decide
Why round robots struggle with corners
Round robot vacuums often leave dirt in corners due to their circular design, which limits their ability to reach edges effectively. For instance, while a round vacuum has a standard diameter, it may miss up to 30% of corner dirt. In contrast, square-shaped robots like the ECOVACS DEEBOT X2 Omni are designed to fit snugly against walls, maximizing cleaning coverage. The difference in edge cleaning can be significant, especially in homes with intricate layouts or lots of furniture.
Ecovacs' Square design: Innovation or Gimmick?
The ECOVACS DEEBOT X2 Omni's square design is not just a gimmick; it’s a strategic advantage. With a height of only 3.74 inches, it can clean under most furniture while its 8,000 Pa suction power ensures deep cleaning on various surfaces. This model also features advanced Dual-Laser LiDAR navigation, providing a 210° field of view for precise mapping. The combination of these specs means that the X2 Omni can navigate complex spaces with ease, adapting to obstacles without missing a beat.
