John W. DeFeo from medium said that High-end robot vacuums use 3D sensors to avoid objects, detect stairs and map rooms, however, even inexpensive robots are getting smarter thanks to affordable sensors that are “coming out of cheap cameras for cell phones,” explained Henrik Christensen to the Robotic Industries Association.
Today, a budget robot vacuum is smarter than a $1,500 robot vacuum from the early 2000s. For example, iRobot’s $199 Create 2 (Roomba) uses PrimeSense sensors like the ones found in iPhones and Kinect cameras.
Nevertheless, robot vacuums are still fairly dumb. They smear wet messes (like dog poop), knock into furniture, and even the most powerful robot vacuums get stuck on high-pile carpet.
