  • Patent number: 11759077
    Abstract: The present invention relates to a floor surfacing machine (1) comprising a frame (2) that is carried by a first wheel (3) and a second wheel (4). The floor surfacing machine (1) further comprises a first motor (6), a handle arrangement (7), at least one planetary head (15) that is rotatably mounted to the frame (2) and at least one satellite surfacing head (19, 20, 21) that is rotatably mounted to the planetary head (15), where the first motor (6) is arranged to propel the planetary head (15). The floor surfacing machine (1) comprises a first control unit (10), and a remote control panel (11) which in turn comprises a second control unit (12) that is arranged to communicate with the first control unit (10). The floor surfacing machine (1) also comprises a second motor (22) that is arranged to propel the satellite surfacing heads (19, 20, 21) such that the planetary head (15) and the satellite surfacing heads (19, 20, 21) are independently operable.
