The ECOVACS Deebot 901 is integrated with Amazon Alexa and Google Home. It can be controlled by a smartphone and via voice commands. If a recharge is required, the robot will stop itself and then pick up where it left off.As with all ECOVACS machines, the Deebot 901 has the same issues connecting to Wi-Fi. It works with a 2.4 GHz speed so make sure you change the settings in your router. It works great on thin carpets and a bare floor but does not do high-pile carpets/rugs. There are some issues that consumers have had about losing the map data. We've searched around and figured out how to avoid this experience and make your robot work as smoothly as possible.The ECOVACS Deebot 901 comes with a minimalistic design, has only one HOME button and a "head" with an LDS laser inside. Underneath you can see an inlet that can be replaced with the main bristle brush or a suction tangle-free inlet. The two side sweepers work together with the main brush, transferring dust and dirt into the inlet where the powerful motor sucks it up to the dustbin. The bristle brush is suitable for a carpeted surface, while the tangle-free one works best on a bare floor and for homes with pets.
