  • Surface maintenance machine light projection
    Patent number: 11859795
    Abstract: A surface maintenance machine includes a body, a surface maintenance tool coupled to the body, processing circuitry supported at the body, and a light projection mechanism supported at the body and coupled to the processing circuitry. The light projection mechanism includes a light housing, a light emitting element within the light housing, and a projection lens that is configured to focus light emanating from the light emitting element. The light projection mechanism is configured to project light onto a ceiling surface that is above a floor surface along which the surface maintenance machine is configured to perform a surface maintenance task using the surface maintenance tool.
