Eden Lichterman from people.com said that Nearly every robot vacuum cleaner on the market has one thing in common: a round design.
While the shape allows those devices to move around without getting stuck, it also prevents them from getting into the edges and corners of your space.
That’s why tons of Amazon shoppers are instead opting for a D-shaped option. And right now, you can get the Neato Robotics D4 Laser-Guided Smart Robot Vacuum for 30 percent off.
This robot vacuum’s D-shaped design and extra large brush allow it to get rid of any pesky crumbs or dust particles hiding in corners and along the walls.
