JOYANCE Cleaning Drones Break Free from GPS Limits: 360° LiDAR and Visual Obstacle Avoidance Open Up Indoor Cleaning

For years, cleaning drones have been confined to outdoor environments. They depend on GPS or RTK signals for positioning, and once they enter indoor spaces, building cavities, or densely obstructed areas, they face signal loss, attitude drift, and even loss of control. JOYANCE (Shandong Joyance Intelligence Technology Co., Ltd.) has addressed this industry pain point head-on: the JTC10 and JTC30 cleaning drones now feature a laser-vision radar and multi-sensor fusion obstacle avoidance system, enabling centimeter-level positioning and stable flight in GPS-denied indoor environments. This extends the cleaning drone's reach from building facades to factory floors, warehouses, large venues, and other areas that were previously out of reach.

Applicable Environments: From "Outdoor Only" to "Indoor and Outdoor"

Traditional cleaning drones require open sky and stable satellite signals. JOYANCE's new solution removes that constraint entirely. The system integrates LiDAR, high-definition RGB cameras, and a high-precision inertial measurement unit (IMU), combined with proprietary SLAM spatial positioning algorithms. It performs real-time spatial positioning and obstacle perception independently, without relying on external high-performance computing hardware.

This means the drone can operate normally in:

• Enclosed indoor spaces: factory workshops, logistics warehouses, large exhibition halls, stadium interiors—anywhere satellite signals are completely unavailable.

• Building cavities and dense areas: narrow gaps between high-rise buildings, underground structures, and roofed industrial facilities.

• Areas with weak or interfered GPS signals: dense urban building clusters and metal-heavy industrial sites.

In these environments, the drone no longer goes "blind" when the signal drops. Instead, it senses its surroundings and maintains hover and flight-path execution using its own onboard sensors, much like an indoor robot.

Application Scope: A Substantial Expansion of Cleaning Scenarios

This technology directly broadens the addressable market for JOYANCE cleaning drones. Previously, the core scenarios were concentrated on outdoor structures such as building facades, glass curtain walls, solar panels, and industrial tanks. Now, the following indoor cleaning needs fall within the executable range:

Factory and warehouse interior cleaning. Walls, ceilings, steel structures, pipes, and equipment surfaces in large industrial plants accumulate dust over time. Manual cleaning requires scaffolding or aerial work platforms—costly and disruptive to production. Drones can perform high-level spray cleaning of interior structures without stopping operations.

Large indoor venues and atriums. Glass roofs and high interior walls in airport terminals, shopping mall atriums, and exhibition halls traditionally require closing the venue and setting up rope access systems. Drones can complete the job quickly during non-business hours, minimizing operational disruption.

Transparent obstacle environments. A key capability of this system is its ability to detect glass, metal mesh, wire mesh, and other transparent or fine obstacles that conventional avoidance radar tends to miss. In interior spaces with glass curtain wall interiors or dense glass partitions, the drone maintains a safe distance without collision.

At the same time, the existing outdoor advantage scenarios—high-rise building facades, window glass, solar panels, concrete tanks, billboards—remain covered, with enhanced safety due to improved obstacle avoidance.

Key Advantages: Why This Technology Matters to Cleaning Service Providers

First, doubled service scope and differentiated competitiveness. Until now, virtually all cleaning drone manufacturers have focused on outdoor scenarios. JOYANCE's indoor flight capability means its customers (cleaning service companies) can take on jobs that previously had to be handed to manual labor or specialized indoor cleaning equipment—expanding from a single exterior-wall cleaning provider to an "indoor-outdoor full coverage" solution provider. JOYANCE states that this technology is exclusively its own; no other cleaning drone manufacturer currently offers a comparable capability.

Second, a structural improvement in safety. Indoor cleaning often involves complex obstacles—steel beams, pipes, equipment, glass partitions. The multi-sensor fusion solution not only provides positioning but also outputs real-time environmental point cloud data, detects obstacles ahead and below, and suppresses flight and attitude drift through fusion algorithms. In glass-dense environments, transparent obstacle detection directly prevents costly collisions.

Third, operational continuity is no longer constrained by signal conditions. Cleaning service providers no longer need to decline projects or add contingency plans because "GPS conditions on site are poor." One device, one set of operating logic, seamless indoor-outdoor switching—reducing equipment configuration and personnel training complexity.

Fourth, JOYANCE's existing efficiency advantages carry over. The new technology does not sacrifice cleaning efficiency. JTC-series cleaning drones cover 1,500–2,000 square meters per hour in outdoor scenarios, far exceeding manual rope access work. While indoor flight speed may be adjusted due to spatial constraints, the efficiency gain over traditional indoor high-level cleaning methods—scaffolding and aerial platforms—remains orders of magnitude.

Conclusion

Competition in cleaning drones is shifting from "how much pressure and how high it flies" to "in what environments it can work reliably." By integrating 360° LiDAR and visual obstacle avoidance into the JTC10 and JTC30 platforms, JOYANCE has taken the lead in solving the challenge of cleaning operations in GPS-denied environments. For cleaning service providers, this redefines the boundary of projects they can take on—indoor high-level cleaning tasks that once depended on manual labor, with low efficiency and high risk, now have a safer and faster technical option.
