The Q7+ from Roborock is a higher-end of their mid-range robot vacuum. This one does come with the auto-empty dock, that’s what makes it a “plus” model over the regular models. It can clean your home for about 180 minutes before it runs out of juice and needs to go back and recharge. This model does have the new redesigned combined dustbin and water tank, which are 470ml and 350ml respectively. That allows them to be larger, and take up even less space inside the vacuum, which is really neat. It can also make a 3D map of your home. Which might seem like overkill for a robot vacuum, but this does allow it to navigate better around your home. For instance, you could have it vacuum in the living room in front of the couch. Instead of the entire room, or the entire floor.
