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.

Embodiments of the present disclosure provide a method for controlling an automatic cleaning device, an automatic cleaning device, and a non-transitory storage medium. The method includes: obtaining a position of a working region of the automatic cleaning device; obtaining a reference data associated with the working region based on the position of the working region; obtaining a current environment parameter of the working region; comparing the current environment parameter with the reference data to generate a comparing result; and controlling the automatic cleaning device based on the comparison result.

Display of a wet cleaning routine of an autonomous floor cleaning robot is provided. Estimated wetness of areas of the floor can be tracked and displayed to the user so they can avoid walking on those areas of the floor until sufficiently dried. The areas of the map that that are still wet from cleaning can be displayed and transition to a different type of indicia over time as the floor dries. The wet floor status can be tracked with a timer by comparing elapsed time since the autonomous floor cleaner traversed the subject region and dispensed cleaning solution with an estimated drying time for cleaning solution on the floor. The estimated drying time can be based upon the flow rate of the autonomous floor cleaner.

This application discloses a cleaning control method applied to be executed by a cleaning robot used with a base station when cleans an unknown area to be cleaned. The method includes: obtaining an area map representing an area to be cleaned or a sub-area to be cleaned which is an uncleaned area in the area to be cleaned; determining a first cleaning starting point of the area to be cleaned or the sub-area to be cleaned based on the area map, the first cleaning starting point being a point on an edge of the area to be cleaned or the sub-area to be cleaned opposite to the cleaning direction; and performing a cleaning operation on the area to be cleaned or the sub-area to be cleaned from the first cleaning starting point. A device, a cleaning robot and a storage medium are also disclosed.

The present disclosure relates to a liquid container and an autonomous cleaning robot. The liquid container may include a container case and a cleaning cloth that is removable and mounted on the container case. The cleaning cloth may include a first guiding member disposed thereon. The container case may include a second guiding member. The first guiding member and the second guiding member cooperate with each other to define an assembly direction of the cleaning cloth. The cleaning cloth can be installed correctly by defining the assembly direction of the first guiding member and the second guiding member.
