Within the robot vacuum, there are a series of powerful sensors located all across the vacuum. Each one of these sensors enables the robot vacuum to determine where it is and where it needs to go. Due to the quality of these sensors, this robot vacuum is able to navigate throughout all manner of spaces with incredible ease.

Right underneath the robot vacuum, there are Dual Multi-Surface Brushes. These two brushes are composed of thick bristles that can sweep and loosen dirt, dust, and debris with ease.
