A vacuum cleaner is provided with a dispensing system for applying a treating agent stored on the vacuum cleaner to the surface to be cleaned. The dispensing system can include at least one container for storing a supply of treating agent and a dispenser for dispensing the treating agent to the surface to be cleaned. The dispensing system uses filtered working exhaust air to blow treating agent off the treating agent dispenser.

A surface maintenance machine is provided having a maintenance head assembly positioned substantially within an envelope of the machine. The maintenance head assembly has at least one maintenance tool attachable thereto. The machine also includes a tool eject mechanism positioned below an upper surface of the body. The tool eject mechanism can generate a drop force sufficient to overcome the force between the maintenance tool and the maintenance head assembly. The tool eject mechanism can have an eject button extending above the upper surface of the deck. The eject button can be actuable by at least a portion of the upper surface of the body of the machine when the maintenance head assembly is raised toward the upper surface of the body of the machine beyond a transport position into a tool eject position. When actuated, the tool eject mechanism can eject the maintenance tool from the maintenance head assembly

Systems and methods for robotic path planning are disclosed. In some implementations of the present disclosure, a robot can generate a cost map associated with an environment of the robot. The cost map can comprise a plurality of pixels each corresponding to a location in the environment, where each pixel can have an associated cost. The robot can further generate a plurality of masks having projected path portions for the travel of the robot within the environment, where each mask comprises a plurality of mask pixels that correspond to locations in the environment. The robot can then determine a mask cost associated with each mask based at least in part on the cost map and select a mask based at least in part on the mask cost. Based on the projected path portions within the selected mask, the robot can navigate a space.

A robot cleaner includes a main body forming an exterior and having a water tank housing formed at a rear side thereof. The water tank housing may form a space in which a water tank is mounted. At least one spin mop is rotatably provided at a lower side of the main body, moving the main body by rotating, and configured to clean a floor using water in the water tank. A supply nozzle is provided at one side of the water tank housing, and when connected to a discharge nozzle of the water tank, communicates with the discharge nozzle to supply water stored in the water tank to each of the spin mops. The robot cleaner further includes a locking device rotatably provided at a position spaced apart from a circumferential surface of the water tank housing, and configured to secure the water tank in the water tank housing when mounted or to release the water tank by pushing backward on the water tank.
