    Abstract: Methods, systems, and devices for performing autonomous self-service are described. A robotic device may identify a status of a chamber associated with the robotic device based on sensor data received from a sensor of the robotic device and pause an autonomous debris collection process of the robotic device based on the identified status. The robotic device may automatically remove a first container from the chamber based on the identified status and discard the first container away from the robotic device. In some examples, the robotic device may discard the first container at a fixed position within a geo-boundary corresponding to the debris collection process. The robotic device may resume the autonomous debris collection process based on an introduction of a second container.

  • Patent number: 10912438
    Abstract: The disclosure relates to a sweeping robot and a cleaning device. The sweeping robot includes: a flexible roller for cleaning the ground, a roller motor for driving the flexible roller to rotate, a pressing member for deforming the flexible roller to press out sewage. Clean water in the clean water sink flows through the clean water hole to the flexible roller. The sweeping robot further includes a sewage sink. The sewage sink is provided with a sewage hole is adjacent to the pressing member. The pressing member deforms the flexible roller, causing sewage to be pressed out of the flexible member and flow through the sewage hole into the sewage sink. The sewage sink is separated from the clean water sink. The cleaning device of the present invention has strong cleaning ability, and the flexible roller is easy to clean.

  • Patent number: 10898047
    Abstract: A fluid collection system for a floor maintenance machine provides improved collection of fluid, foam, and debris prior to the vacuum source. The fluid collection system includes a recovery chamber defining a volume, a hollow structure (such as a modified skirt) having an internal chamber, and a vacuum source in fluid communication with the volume of the recovery chamber via the internal chamber and a vacuum line. The vacuum source draws a vacuum in the volume of the recovery chamber by drawing a gas from the volume of the recovery chamber through the internal chamber of the hollow structure and through the vacuum line.

  • Patent number: 10850313
    Abstract: The invention relates to a cleaning device for the dry cleaning of a tunnel, comprising a feeding device for feeding a flow of air to a surface being cleaned, wherein the feeding device has an exit opening, through which the flow of air emerges from the feeding device, and a removal device comprising at least one removal pipe with a free end with an opening for suctioning away direct or trash from the surface with the opening of the free end in a first direction. The feeding device is arranged such that the flow of air from the exit opening emerges from the feeding device in a second direction toward the opening of the free end of the removal pipe and impinges on the surface. The first direction is oriented at an angle between 45° and 80° to the second direction.

  • Patent number: 10813521
    Abstract: Aspects of the present invention relate to a triggerless extractor surface cleaning device for cleaning a surface in which a cleaning solution is distributed to the surface and extracted using suction along with dirt and/or debris on the surface in a continuous operation as the extractor moves along the surface. The extractor further comprises an encoder positioned adjacent a wheel of the extractor for detecting a rotational direction and speed of the wheel to generate a signal. Based on receiving the signal, a controller controls operation of a valve to situationally distribute the cleaning solution to the surface depending on a forward rotation of the wheel and independent of user actuation of a trigger positioned on a handle used to propel the extractor along the surface. Distribution of the cleaning solution can be further optimized based on the detected rotational speed of the wheel.
