A virtual wall is a device that makes a false wall.
Intelligent sweepers work according to the mode of travel, usually encounter obstacles or wall gently bump sensor, will turn or turn, so the virtual wall can help us to carry out zonal cleaning. For example, the location of the living room and dining room, we want him to clean the dining room first and then the living room, then we can put the virtual wall in the area we want to separate.
Virtual walls can emit infrared signals to block sweeping robots from entering the space they don't want users to enter. You just treat this signal as an invisible "wall". If the open kitchen, bathroom and other floor sweeping robots are easy to enter, but easy to cause trouble in the area, you can set up a virtual wall to prevent the floor sweeping robots from entering these areas; for example, you read in the study, do not want the floor sweeping robots to disturb the study, at this time, putting a virtual wall in the door can play the same effect as closing the door of the room.
