One of the most reliable robotic vacuum brands is iRobot. Until now, the company has produced and designed various robots that are meant to ease your work at home and spend more time enjoying the things that you like. iRobot Roomba is not the latest device made by the company but is one of the most popular ones. It is the upgraded version of Roomba 650 so it comes with some extra features, as the Wi-Fi connectivity. If we compare it to Roomba 800 and 900 series, it lacks some advanced features but the price makes it more accessible for many people. Plus, it does a decent job when it comes to keeping your floors clean.
