2. Brief introduction of the company's main business during the reporting period

2.1 Main business, main products or services

The company's main business is the design, research and development, production and sales of intelligent hardware such as intelligent sweeping robots, and the main products include intelligent sweeping robots, floor scrubbers, washing and drying machines and other intelligent electrical appliances:

1. Intelligent sweeping robot

The company is an international leader in the large-scale application of lidar technology, radar lifting technology, 3D-TOF navigation technology, precision optical visual navigation obstacle avoidance and related algorithms in the field of intelligent sweeping robots.

After the intelligent sweeping robot builds a household map based on the SLAM algorithm of laser or TOF and other ranging sensors, vision sensors, inertial measurement units and other sensors, it is positioned according to the household map, and at the same time, an intelligent and efficient cleaning path is planned through the AI algorithm, which can effectively avoid missing and re-scanning. On the server side, through deep learning and algorithm optimization of Internet product data, the robot algorithm is continuously iteratively upgraded.

At the same time, in addition to the original basic functions, the new products of the sweeper have also been developed with hot water to wash the mop, self-cleaning of the rag, anti-winding of the brush, intelligent maintenance-free, chassis lifting, dynamic double-arm sweeping and mopping, multi-axis bionic manipulator, three-line structured light, RRMind GPT intelligent interaction and other functions, which have promoted the sweeping robot to achieve a qualitative leap on the road of intelligent development.

2. Floor scrubber

In order to improve the cleaning effect and user experience, the company has conducted in-depth research and development and applied the latest research and development results to related products, including double roller brush system, intelligent washing and drying and full-link antibacterial, automatic delivery of cleaning liquid, intelligent control of fluid and heat energy to achieve dual heat system, AI two-way power assist system, intelligent brush head and other technologies, so that the floor cleaning ability of the floor scrubber and the self-cleaning ability of the machine have been improved, the dual effect of antibacterial and anti-odor has been enhanced, and the convenience of use has been improved.

3. Washing and drying machine

With the development of living standards, users' needs for laundry cleaning have gradually escalated, not only for clothing drying, but also for the partition washing and care of laundry. There are many deficiencies in the experience of the existing washing and drying machine, which cannot bring the ultimate experience to customers and is difficult to meet the expectations of users for products. To this end, the company has developed the "third drying technology (molecular sieve adsorption drying) washing and drying machine", which not only solves the problems of high drying temperature, excessive lint residue, residual pollution of drying air duct, poor drying effect, and long drying time, but also meets the mainstream embedded home decoration scene, without taking up more additional home decoration space. Different from condensing or heat pump drying, the company's products use physical adsorption technology, use the super moisture absorption ability of molecular sieves to dehumidify clothes, cooperate with the industry's first dual-air circulation system, independent partitioning, keep the main circulation air path relatively dry circulating warm air, and the circulating air path has no active heat source, so as to achieve low-temperature drying care. The product can not only dry high-end fabrics such as silk and wool, but also improve the drying efficiency, achieve the effect of efficient drying, and solve the problems of dander adhesion and debris pollution of the traditional washer-dryer. The company continues to promote technological innovation and product innovation, deeply cultivates the iterative upgrading of molecular sieve drying modules, and successfully launches modules suitable for mini washing machines, economical drum washer-dryers and ultra-thin washer-dryers, further expanding product application scenarios to meet the diverse needs of different customer groups. The company has the courage to break through the traditional thinking, and changes the way of driving the molecular sieve turntable to rotate from complex gear transmission to direct drive, simplifying the mechanical structure, reducing the failure rate, and making the drying process more stable and quiet. furthermore

In addition to the original basic functions, new functions such as mousse washing, dual-channel automatic delivery of ink cartridges, and voice control have been added, so that the washing and drying machine has gone further in improving the cleaning effect, convenience and intelligent experience, and has brought users a new choice of more relaxed, efficient and personalized laundry.

2.2 Main business model

The company closely focuses on technology research and development and brand building, and continues to build and enhance the company's core competitiveness, and gains market share through the leading technology and product leadership and excellent brand image. In terms of procurement, the company mainly focuses on direct procurement, supplemented by factory self-procurement. In terms of production, the company combines independent production and outsourced processing in self-built factories. In terms of sales, the company adopts a combination of online and offline sales model.
