Commercial cleaning robots

Commercial cleaning robots are critical automated devices in smart sanitation and property management. They are widely used for daily cleaning operations in large-scale settings such as shopping malls, airports, train stations, hospitals, office buildings, factory workshops, and municipal roads. Equipped with cleaning components such as scrub decks, squeegees, and waste bins, these cleaning robots utilize autonomous navigation and path planning to achieve round-the-clock, highly efficient automated cleaning, effectively replacing traditional manual labor.

In our product applications, linear actuators primarily handle core tasks such as raising and lowering the scrub deck, raising and lowering the squeegee, and tilting the waste bin. During the scrubbing process, the actuators automatically adjust the height of the scrub deck based on floor conditions to ensure optimal contact pressure between the deck and the floor. Once waste collection is complete, the actuators drive the lifting and tilting of the waste bin to automatically dump the waste into a collection container. Compact, easy to install, and maintenance-free, these linear actuators operate reliably within the limited underside space of cleaning robots. By replacing traditional hydraulic and pneumatic solutions with precise linear motion, they provide efficient, reliable, and low-maintenance automated power for commercial cleaning applications.

Key features and benefits

Precise control ensures consistent cleaning performance

The contact pressure between the scrub deck and the floor directly determines cleaning performance. Our linear actuators provide precise stroke control and extremely high repeatability, ensuring the scrub deck maintains optimal contact pressure under all floor conditions—hugging the surface precisely on flat surfaces and automatically making micro-adjustments to compensate on uneven surfaces. The motion trajectory remains completely consistent for every cleaning task, fundamentally ensuring a high degree of consistency in cleaning results.

Fast response, adapting to dynamic cleaning rhythms

Commercial cleaning robots need to adjust scrub deck height in real time during operation based on floor material, soil level, and the presence of obstacles. Our linear actuators feature extremely fast response times—the time from receiving a control signal to the actuator completing the motion is minimal—ensuring that cleaning robots can instantly adjust scrub deck height even while moving at high speeds, without missing any area requiring thorough cleaning.

High protection rating, confidently handling humid and dust-filled environments

The operating environment of cleaning robots is filled with corrosive substances such as water, cleaning agents, and dust. Our electric linear actuators feature a high protection rating, providing full resistance against the intrusion of moisture and dust. Constructed from corrosion-resistant materials and featuring a fully sealed design, they ensure stable and reliable performance even during prolonged exposure to water and cleaning agents. Certain models can withstand high-pressure water jet washing, meeting the rigorous cleaning and maintenance demands of commercial cleaning equipment.

Compact and lightweight, they do not take up valuable internal space in robots

The internal space of commercial cleaning robots is extremely limited, requiring the integration of multiple systems—including navigation systems, battery packs, water tanks, and cleaning mechanisms—onto a compact chassis. Our linear actuators are known for their ultra-compact design and lightweight construction, allowing them to be easily integrated into the limited space of the scrub deck lifting mechanism and waste bin tilting mechanism, reliably completing every cleaning operation without interfering with the layout of other components.

Long service life and maintenance-free operation, reducing total cost of ownership

Commercial cleaning robots often require round-the-clock, uninterrupted operation; frequent maintenance directly impacts equipment availability and operating costs. Our linear actuators feature a maintenance-free design that requires no periodic lubrication or replacement of wear-prone parts. Validated through tens of thousands of durability tests, they ensure stable operation throughout the equipment's entire lifecycle.

Built-in Hall sensors enable precise control for customers

Our actuators feature built-in Hall sensors that provide real-time feedback on stroke position and operational status via pulse signals. Based on this data, the customer's control system can precisely manage key parameters such as the scrub deck height and the waste bin tilt angle, enabling accurate closed-loop control. The real-time feedback from the Hall sensors provides a precise basis for robots' autonomous decision-making—from real-time monitoring of the scrub deck's ground contact pressure to confirming the completion of waste dumping, every action is executed with precision under closed-loop control.

Richmat's engineers provide end-to-end technical support—from needs assessment and solution design to product delivery—ensuring that our reliable linear drive systems safeguard every moment of cleaning and efficient operation.

Other Applications

Robot training hangers

Robot training hangers are indispensable testing and debugging platforms in the research, development, and production of humanoid robots. They are widely used by humanoid robot manufacturers, research laboratories, embodied intelligence R&D institutions, and similar facilities. Before a humanoid robot leaves the production line, it must undergo rigorous systematic training and calibration to ensure joint flexibility, hand-foot coordination, and movement balance. The robot training hanger suspends the robot in the air via an overhead track or a mobile head unit, enabling various command tests, joint motion training, and limb coordination adjustments to be performed on the robot under safe and controlled conditions.

In our product applications, linear actuators serve as the core drive components for height adjustment and fine-tuning of the suspension system's orientation. Driven by commands from the control system, the linear actuator precisely adjusts the height and suspension angle of the robot training hanger—gently lifting the robot to the suspended training position when raising it, and gently lowering it back to the ground when lowering it. The actuator operates smoothly, moves with precision, and responds quickly, maintaining stable and reliable lifting performance even while supporting the robot's weight.

Robot head adjustment systems

Robot head adjustment systems are the core actuators that enable head pitch and rotation in service robots, humanoid robots, and specialized robots. They are widely used in applications such as reception and guidance robots, educational companion robots, security patrol robots, and humanoid robots. The flexible movement of a robot's head is not only the hardware foundation for multi-angle environmental perception but also a core element in endowing the robot with "human-like" interactive capabilities—the smoothness of the head's up-down pitch and left-right rotation directly determines whether the robot appears agile or stiff to users.

In our product applications, miniature linear actuators serve as the core drive components for the robot's neck joints. Through precise linear motion, these actuators drive the robot's head to perform pitch and rotation movements around the joint axis. Small in size, compact in structure, and quiet in operation, these linear actuators fit perfectly into the robot's limited neck space, enabling stepless adjustment of the head's angle through precise stroke control. Compared to traditional servo or stepper motor solutions, electric linear actuators offer smoother motion curves, lower operating noise, and higher torque density, making the robot's head movements more natural, fluid, and lifelike.

Lifting robotics

Lifting robots (also known as torso robots or elevating mobile robots) are a new type of robotics that has garnered significant attention in recent years in the fields of embodied intelligence and mobile robotics. They are widely used in scenarios such as industrial inspections, warehousing and logistics, commercial services, and security patrols. The lower half of a torso robot is connected by lifting columns, which enable the vertical movement of the robot's upper body through their telescoping motion. This design allows the robot to flexibly adjust its field of view and operational range according to task requirements—navigating through low-clearance spaces when in the lowered position and surveying the entire scene from an elevated position.

In our product applications, lifting columns serve as the core structural component and power actuator of the torso robot. They convert the rotational motion of a low-voltage DC motor into smooth linear lifting motion, supporting the entire weight of the robot's upper body and enabling precise height adjustment. Lifting columns feature a robust structure and stable operation, capable of withstanding high dynamic and static bending moments. As the robot's "waist and legs," the lifting column not only determines the robot's viewing height but also defines its core ability to maintain postural stability during vibrations and movement.
