Robotic pool cleaner

A robotic pool cleaner includes a cleaning body, a drive and a cleaning roller brush mechanism. The robotic pool cleaner filters liquid and/or contaminants in a pool through the cleaning body. The drive mechanism is connected to the cleaning body, which is driven to move in the pool in a working process of the robotic pool cleaner. The drive mechanism includes a drive wheel with a first outer ring gear. The cleaning roller brush mechanism is coupled with the first outer ring gear through a transmission belt, so that the cleaning roller brush mechanism is driven by the first outer ring gear to rotate relative to the cleaning body when the drive motor drives the first outer ring gear to rotate. The robotic pool cleaner improves cleaning efficiency and reduces wear of a cleaning roller brush, thereby prolonging the service life of the cleaning roller brush mechanism.

In a method for invitation behavior prediction, group behavior feature information of a first user of a group is obtained. In addition, group relationship feature information of a second user is obtained. Further, group architecture information of the group, the group behavior feature information of the first user, and the group relationship feature information of the second user are input to an invitation prediction model, to obtain a target member user and a candidate invitation user of the target member user. The invitation prediction model is obtained by training the invitation prediction model based on a plurality of sample groups in a training set, and group relationship feature information of associated users of member users in the plurality of sample groups. Invitation prediction information is sent to the target member user to prompt the target member user to add the candidate invitation user to the group.
