Robot vacuums save time with autonomous cleaning, but they are not a like-for-like replacement for human cleaners. Most lack arms to move obstacles like chairs or cables, requiring users to clear floors beforehand. Navigation varies by price: basic models rely on bump sensors, while premium units use LiDAR and AI cameras to identify problems.

However, even advanced models struggle with loose cables, socks, and lightweight rugs unless specifically designed to move objects. Certain floor types also pose challenges, as thick carpets and raised rug edges can hinder performance. Suction power alone does not guarantee effective cleaning, as brush design and surface transitions matter significantly.

While convenient, robot vacuums still demand floor preparation and may miss deep-seated dirt in specific environments.
