Development Analysis of Rewei Co., Ltd. in the Smart Cleaning Appliances and Smart Home Fields

Rewei Co., Ltd. clearly stated on the interactive platform that Dreame Technology (Suzhou) Co., Ltd. is already its customer, and the electric heating components supplied are mainly used in smart cleaning appliances such as floor washers and sweeping robots. Moreover, the company recognizes smart home as a new growth point in the future; it has accumulated multiple customers in the cleaning appliance category and plans to continue expanding product applications in this field [1]. This means Rewei has obtained an entry point into core scenarios (such as floor cleaning robots and floor washing equipment). Its supporting capabilities and customer stickiness in the supply of electric heating components will further improve, which is also conducive to expanding to more scenarios (kitchen, clothing care, air purification, etc.) through the smart home ecosystem.

1. Rapid Industry Growth and Significant Intelligent Upgrade
   : Statistics from Aowei Cloud Network and others show that the sales volume of China’s cleaning appliance industry reached 42.3 billion yuan in 2024, with a year-on-year growth of 24.4%. Among them, intelligent upgrades driven by AI large models, such as recognition and obstacle avoidance, voice interaction, have become important engines for the accelerated popularization of categories like sweeping robots [2]. The enhancement of such intelligent capabilities requires upstream modules to provide higher-performance thermal management, heating, drying, and other capabilities, offering supporting opportunities for electric heating enterprises with technical R&D and customization capabilities.
2. Volume Release of Emerging Categories and Evolution of Unit Price Structure
   : Emerging cleaning equipment such as floor washers have experienced explosive growth in recent years. In 2024, the omni-channel sales amount jumped from 100 million yuan in 2019 to 14.1 billion yuan (a compound annual growth rate of about 192%), and the sales volume increased from 20,000 units to 6.63 million units (a compound annual growth rate of about 209%). Although the average price shows a downward trend, the overall scale has expanded significantly [3]. Floor washers adopt differentiated technologies such as high-temperature steam and hot water cleaning (e.g., Roborock A30 Pro Steam can quickly heat up to 150°C), which puts forward higher requirements for the response speed, temperature control accuracy, and reliability of electric heating components [3]. This is exactly the application scenario of the thick film and high-efficiency heating solutions that Rewei excels in.

1. Customized Heating Modules as Core Capabilities for Smart Cleaning
   : As sweeping robots and floor washers add functions such as heating and drying, steam sterilization (e.g., industry practices show dual-effect cleaning with steam and hot water), electric heating components need to meet indicators such as rapid temperature rise, uniform temperature, waterproofing, and dustproofing. Rewei can combine technologies like thick film, ceramics, and electric heating film to provide core heating modules with high density, fast response, and long lifespan, participating in the front-end layout of product differentiation.
2. Verification and Channel Synergy Enhance Moat
   : High-end cleaning appliance brands have strict requirements for quality and consistency, and new customers usually prefer those with an “excellent supplier” background. Rewei has accumulated many domestic and foreign leading home appliance customers, and has good cases in smart home segments such as cleaning appliances, which helps expand to robot manufacturers other than Dreame and overseas brands through demonstration effects.
3. Expansion of Smart Home Ecosystem Drives Product Line Extension
   : Smart cleaning scenarios need to collaborate with IoT control, AI scheduling, and cloud data. If electric heating components are linked with sensing and control modules, they can expand to more细分 scenarios such as intelligent drying, hot air drying, and electric heating steam, and then transform into “module + service” solutions, increasing the lifetime value of a single customer.

1. Production Capacity and Delivery Guarantee
   : As the shipment rhythm of cleaning appliances accelerates, Rewei needs to ensure production capacity expansion and automation level, and maintain supply chain stability in key components (such as high-temperature insulating materials) to meet the batch demand of large customers.
2. Continuous R&D and Customization Capability
   : In the face of differentiated thermal management needs, Rewei should increase R&D investment in high-temperature materials, flexible heating, rapid temperature control, etc., to improve the response speed of new products from prototype to mass production.
3. Customer Order Structure and Concentration Risk Management
   : While deepening cooperation with new customers like Dreame, Rewei also needs to continue to maintain traditional businesses such as kitchen and bathroom/clothing care to avoid fluctuations caused by over-reliance on a single customer or category.

Rewei Co., Ltd. has established a customer base in the smart cleaning appliance field and is actively extending to the smart home ecosystem. Considering that the industry continues to be driven by “intelligence + scenario”, the rapid expansion of cleaning appliance scale, and the core position of electric heating components in differentiated cleaning functions, Rewei has a good opportunity to upgrade its product portfolio through technical capabilities and attract new customers with customer cases. It is recommended to pay attention to the stability of the company’s orders in the smart cleaning segment, production capacity layout, and R&D rhythm, while keeping an eye on thermal management system innovations for smart scenarios to consolidate its strategic position in the smart home system.
