An automated parking garage with one or more novel features described herein. These novel features include a modular design a control system that is operable to move multiple items, such as vehicles, independently so that they can move concurrently or simultaneously, at least one storage space that comprises an electric vehicle charging station, the ability to communicate with autonomous (e.g., self-driving) vehicles to facilitate parking of autonomous vehicles, a pallet cleaning system, and/or can be configured to store containers or other items.

An autonomous cleaning device, a method of control the autonomous cleaning device, and a storage medium are provided. The device includes a body, and a cleaning assembly, a driving assembly, wheels, a plurality of detection sensors and a controller on the body. The plurality of detection sensors are configured to transmit detection signals and receive reflection data of the detection signals reflected by an obstacle. The controller is configured to obtain reflection data reflected by the obstacle and received by the plurality of detection sensors, determine whether the obstacle has a gap according to the reflection data received by the detection sensors, and in response to the obstacle having the gap, control the autonomous cleaning device to travel, by sending control instructions to driving assembly, according to the reflection data at different time points and basic information of the autonomous cleaning device.

An autonomous cleaning device and a noise reduction air duct device are provided for autonomous cleaning device. The autonomous cleaning device includes a body and a motor arranged on the body, and the noise reduction air duct device is mounted on the body. The noise reduction air duct device includes an upper housing, a lower housing and a support noise reduction structure made of elastic material. The lower housing and the upper housing enclose to form an air duct, an air inlet is arranged at a position of the air duct corresponding to the motor, and an air outlet is arranged on a side of the air duct away from the air inlet; the support noise reduction structure has a first end fixed on the lower housing, and a second end abutting against a lower surface of the upper housing.

An automatic cleaning apparatus includes: a chassis; a front housing arranged at a front end of the chassis; and a sensing device capable sensing movement of the front housing and sending a signal to a control mainboard of the automatic cleaning apparatus when the front housing touches an obstacle and moves relative to the chassis. The sensing device includes a dust blocking member and a rocker arm that triggers the sensing device to send the signal. The rocker arm has a first end rotatably arranged inside the sensing device, and a second end passing through the dust blocking member and extending out of the sensing device. A front housing reset device is arranged on the chassis and capable of biasing the front housing toward an initial position of the front housing.

A filtering device for an evacuation station includes a filter bag configured to collect debris evacuated from a cleaning robot by an evacuation station. The filtering device includes an interface assembly configured to interface with the evacuation station. The interface assembly includes (i) a base attached to the filter bag along an opening of the filter bag, (ii) an access door configured to provide or limit access to a space within the filter bag depending on whether the access door is in an open position or a closed position, and (iii) one or more hinges connecting the base to the access door. The access door is rotatable around the one or more hinges from the closed position to the open position.

A touchless cleaning assembly for cleaning a room in a touch-less manner includes a cabinet is recessed into a wall of a room. A plurality of hose reels is positioned in the cabinet and each of the hose reels includes a hose that is drawable outwardly from the cabinet for spraying a fluid for cleaning surfaces in the room, for blowing air to dry the surfaces and to vacuum the surfaces. An air compressor is positioned within the cabinet to direct compressed air into a respective hose reel to dry the surfaces. A vacuum is positioned within the cabinet to supply vacuum pressure to the a respective hose reel for suctionally removing the fluid from a floor of the room.

A billiard table cleaning device for autonomous cleaning of a playing surface of a billiard table includes a housing, which defines an interior space and which has at least one linear side. A drive unit is engaged to a bottom of the housing and is configured to selectively motivate the housing across a playing surface of a billiard table. A vacuum assembly is engaged to the housing and is positioned in the interior space. The vacuum assembly suctions air and debris, such as chalk dust, through slots positioned in the bottom and expels filtered air through vents positioned in or proximate to a top of the housing, thereby cleaning the playing surface.
