The iRobot Roomba 675 is another popular robotic vacuum cleaner that offers a replaceable battery. It uses a three-stage cleaning system to thoroughly clean your floors, and its dual multi-surface brushes can handle both carpets and hard floors. The replaceable battery ensures that you can easily replace the battery when it starts to lose its capacity, allowing you to continue using the vacuum cleaner for years to come. With Wi-Fi connectivity, you can control the vacuum cleaner through a smartphone app or voice commands.
