Robot vacuums keep getting smarter every year. Take the Ironpie vacuum for instance: it is a robot that uses a smart vision system and Armv8-A quad-core processor to clean the floor efficiently. It is smart enough to identify areas that have not been cleaned.
The robot can avoid obstacles. It can be even be used as a surveillance device. The Trifo Home app allows you to put the robot on a schedule. Ironpie is compatible with Amazon Alexa.
