You can not only control the iRobot Roomba s9+ via your mobile phone, but via Alexa or Google Home as well. After a while, the smart navigation method maps your home and gives rooms a name in its memory. That way, you could simply tell your voice control system that the robot has to clean the bedroom, and it'll understand exactly which room you mean. You won't need to do anything until after a few rounds of vacuum cleaning. The robot vacuum empties its dust container in a vacuum cleaner bag at the docking station, instead of keeping it in its small dust container. The robot's unique shape allows it to clean corners better than its round colleagues. If you add the short charging time and the good suction power, this household help won't let you down any time soon.
