Deeply cultivated for 15 years, market share is the proof of trust!
After robot vacuums, where will the next explosion point for home service robots be?
The answer is emerging from the glass curtain walls of high-rise buildings—window cleaning robots.
And the first to provide the standard answer was Ecovacs (科沃斯).
Recently, Ecovacs (科沃斯) under its "Winbot" (窗宝) handed in a report card that has attracted the industry's attention: sales exceeded 1 million units in 2025, with a global cumulative total of over 2.6 million units, a compound annual growth rate of 50% over the past 5 years, and a 70% growth in transactions within the year. It has instantly become the second million-unit blockbuster created by Ecovacs (科沃斯) following the robot vacuum.
Behind the impressive data lies a rigid demand that has been long overlooked and is now experiencing a concentrated outbreak.
Driven by multiple factors such as the rapid popularization of high-rise residential buildings, rising costs of manual window cleaning, and prominent safety risks associated with high-altitude operations, facade cleaning is no longer an "optional item" but has become a must-do task for more and more households. Consequently, window cleaning robots have ushered in a window of opportunity for explosive industrial scale.
1. Rigid demand resonates with technology, a new 10-billion track rises
According to the international market research firm Stratistics MRC, the global window cleaning robot market size is projected to grow from $584 million in 2025 to $2.204 billion in 2032, with a compound annual growth rate as high as 20.9%. A multi-billion dollar track is already clearly visible.
Looking back at the development history of this category, window cleaning robots were almost in a blank state before 2010.
In 2011, with breakthroughs in vacuum suction and magnetic suction technology, Ecovacs (科沃斯) pioneered the industry by launching the first household automatic window cleaning robot, "Winbot 5 Series," jointly initiating the marketization process of vertical surface cleaning with other industry brands.
For more than ten years after that, this category was steadily cultivated. In 2024, an industry inflection point suddenly appeared: data from AVC (奥维云网) showed that the market size of household window cleaning robots in China reached 1.14 billion yuan that year, a year-on-year increase of 35.7%, breaking the 1 billion yuan mark for the first time; the online sales growth rate was as high as 91.37%, ranking first among cleaning appliances.
The momentum of the outbreak further accelerated in 2025. IDC data shows that global shipments of window cleaning robots reached 2.373 million units, a year-on-year increase of 70.4%; in the first quarter of 2026, transactions on the Tmall (天猫) platform grew by over 70% year-on-year, and rental orders surged by 376%. The pattern of booming domestic and foreign sales has officially taken shape. The industry expects global shipments to exceed 3 million units in 2026, making window cleaning robots the strongest new growth driver in the smart cleaning industry.
This round of explosion is not accidental, but the result of the resonance of multiple dividends in demand, technology, and channels, and the industry has officially entered the window period of large-scale explosion.
On the demand side, the rapid popularization of high-rise residential buildings has made pain points such as high safety risks of traditional manual window cleaning, rising housekeeping costs, and limited cleaning efficiency increasingly prominent.
Meanwhile, the pace of modern life has accelerated. Most people neither have large blocks of time to handle heavy housework, nor do they have the physical strength and professional capabilities to complete high-altitude facade cleaning. This emerging niche demand has directly catalyzed the popularity of on-site cleaning services and various smart cleaning tools.
Against this backdrop, facade cleaning has upgraded from an optional household chore to a rigid family necessity. Combined with consumption upgrades driving home cleaning towards all-scenario, zero-risk, and fully managed directions, these factors are jointly propelling the window cleaning robot industry into a window of large-scale explosive growth.
On the supply side, core industry technologies continue to iterate and achieve breakthroughs. Key modules such as adsorption systems, intelligent navigation, safety protection, and automatic docking stations are constantly maturing, effectively solving industry challenges like high-altitude falls, missed cleaning spots, and the need for frequent manual intervention. The product experience is undergoing a comprehensive upgrade from "usable" to "easy to use and user-friendly," significantly lowering the barrier to entry and driving window cleaning robots from niche circles into the mass market.
At the channel level, model innovation continues to break boundaries, accelerating the industry's scale-up. Diverse models such as rental services, whole-house smart packages, on-site cleaning services, and home furnishing bundles are rapidly emerging. These effectively lower the barrier for users to try, covering different consumer groups such as trial users, short-term users, and low-frequency users, helping window cleaning robots steadily move from "niche trials" to "mainstream popularity".
With the continuous expansion of application scenarios such as home and commercial use, and the constant emergence of hot trends like the leasing economy and smart bundle purchases, multiple factors are working together to drive the continuous expansion of the window cleaning robot track, making it the new growth pole with the most certainty in the smart cleaning field.
And amidst this wave, Ecovacs Winbot (科沃斯窗宝), with its 15 years of deep cultivation, has become the top choice for users when purchasing window cleaning robots. At this critical stage where the industry is entering a window of large-scale explosive growth, it firmly occupies the core position in market perception and actual selection.
2. Anchoring on users and safety, Ecovacs (科沃斯) has charted a second growth curve through long-termism.
Against the backdrop of the window cleaning robot industry entering a window of explosive growth and the continuous release of the track's potential, not all companies can seize the opportunity.
While most peers were still tentatively exploring cross-boundary moves to find growth directions, Ecovacs (科沃斯) has been deeply cultivating this field for 15 years. With firm long-termism, it has completed the layout from category creation to global leadership.
Ecovacs (科沃斯) continuously drives technological iteration, and the Window Robot has undergone 7 generations of core product upgrades. It has successively achieved key leaps from vacuum suction to fan suction, from wired constraints to wireless freedom, and from manual operation to full base station management, constantly refreshing and leading industry technical standards.
At the same time, the demand for window cleaning among domestic households has also undergone structural changes: window cleaning is no longer just a seasonal chore of "cleaning only once a year during the Spring Festival," but has extended to multiple high-frequency scenarios such as after heavy pollution weather, seasonal deep cleaning, initial cleaning of new homes, and finishing touches after renovations, becoming a normalized and repetitive household labor.
In addition, large areas of clear and tidy glass have become an important symbol of quality of life and a sense of residential dignity. The resonance between mature technology and upgraded demand has made Ecovacs Winbot (科沃斯窗宝) the default option for consumers when purchasing window cleaning robots.
Market data shows that in 2025, Ecovacs Winbot (科沃斯窗宝) achieved a sales share of over 60% in the Chinese market and a global market share of over 31%, becoming the undisputed definer and rule-maker in the window cleaning robot sector.
It is worth mentioning that Ecovacs (科沃斯) is also the only brand enterprise in the world with a complete product line of household and commercial service robots, truly achieving full-scenario coverage for both home and commercial settings. As early as the drafting of the industry standard "Household and Similar Use Window Cleaning Machines" by the Ministry of Industry and Information Technology in 2023, Ecovacs (科沃斯) was the only private enterprise to participate, leading the standard construction with its technical strength and industry responsibility.
This leading position stems from the long-termism consistently upheld by Ecovacs (科沃斯).
Compared to its peers, Ecovacs (科沃斯) has not blindly chased the cross-industry trends. Instead, anchoring on user needs and safety baselines, and guided by user pain points beyond floor cleaning robots, it has focused on the vertical cleaning niche and precisely pioneered the new category of window cleaning robots. Over the past 15 years, it has upheld the core product values of "safety + efficiency," refused short-term speculative layouts, and carved out a differentiated growth path.
Ecovacs (科沃斯) founder Qian Dongqi once frankly admitted, "It took us 10 years to pioneer the window cleaning robot category." These ten years represent a complete cycle, from technological exploration and market education to the cultivation of user habits. In the eyes of consumers, early window cleaning robots were more like novel toys than practical cleaning tools. During this long period of accumulation, Ecovacs (科沃斯) completed a key strategic layout from category creation to technological dominance.
In the first half of 2025, Ecovacs (科沃斯) brand service robots achieved revenue of 4.805 billion yuan, accounting for 55.39% of total revenue, continuing to lead the home service robot sector. As the second million-unit blockbuster following the Deebot (地宝), the Winbot (窗宝), along with new categories such as robotic lawn mowers and pool robots, has become a new engine for the performance growth of Ecovacs (科沃斯) service robots. It not only contributes stable revenue and profit increments but also drives Ecovacs (科沃斯) to upgrade from single-floor cleaning to a comprehensive cleaning ecosystem covering both floors and vertical surfaces, becoming a key force supporting a 24.37% year-on-year increase in total revenue and a 60.84% year-on-year increase in net profit attributable to shareholders.
This user-centric, deep-dive vertical track strategic choice has not only forged a strong and reliable second growth curve for Ecovacs (科沃斯), but also provided a replicable model for the entire smart cleaning industry to break through growth bottlenecks. With 15 years of practice, Ecovacs (科沃斯) has proven that a truly sustainable second growth curve is not about blindly expanding across boundaries or trading scale for growth, but rather about grounding in user needs and continuously deepening efforts in vertical tracks. Through technological iteration and category innovation, it achieves category creation from 0 to 1 and track dominance from 1 to N, ultimately building a competitive barrier that is difficult to replicate.
3. Winbot (窗宝) ignites ecological momentum, rewriting the competitive landscape of home robots
According to a report by CCTV Finance, window cleaning robots have entered a golden phase of booming supply and demand both at home and abroad, and rapid industry growth.
In the first quarter of 2026, domestic online transactions grew by over 70% year-on-year, and leasing orders surged by 376% year-on-year; data from Huangpu Customs shows that exports grew by 65.3% during the same period, far exceeding the overall growth rate of mechanical and electrical products, with Europe becoming the core overseas market.
Shenwan Hongyuan Securities (申万宏源证券) analyst Cheng Kaiwen pointed out that global shipments are expected to exceed 3 million units in 2026, and the industry is still in a blue ocean market with broad room for growth. Window cleaning robots not only efficiently solve the rigid demand for high-altitude window cleaning in households, but also achieve a 10% cost reduction and significantly improved safety in commercial scenarios. By reconstructing the facade cleaning service system with a "human-machine collaboration" model, they have become a golden track that combines both public value and industrial prospects.
In this industrial transformation, Ecovacs (科沃斯) is not only a participant and witness, but also the creator of the category and the rule-maker. With Winbot (窗宝) as the core, it has ignited ecological momentum and promoted the reconstruction of the competitive landscape of household robots.
At the strategic level, Ecovacs (科沃斯) uses its self-developed full-stack robotics capabilities as a core engine to continuously drive the large-scale implementation and explosive growth of new product categories.

Relying on over twenty years of deep accumulation in perception, decision-making, motion control, AI algorithms, and industrial chain manufacturing, Ecovacs (科沃斯) has built a reusable, transferable, and iterative underlying capability system. This efficiently converts the technological accumulation of mature tracks into a first-mover advantage for new categories, enabling every new category to stand on the shoulders of existing technology and rapidly mature.
Currently, Ecovacs (科沃斯) has completed a full-scenario layout ranging from ground to vertical surfaces, from indoor to outdoor, and from cleaning to companionship. The million-selling hit status of the Winbot (窗宝) is precisely the successful implementation of this capability stack in the vertical surface cleaning scenario. Meanwhile, the sustained sales growth of robotic lawn mowers and pool cleaners, along with the smooth market launch of new embodied intelligence products such as the Bajie Butler Robot (八界管家机器人) and the Mao Tuan'er Bionic Companion Robot (毛团儿仿生陪伴机器人), further prove that the robot capability stack can be efficiently reused across scenarios and categories. This opens up growth potential far exceeding that of a single track for Ecovacs (科沃斯) at a critical stage as the industry enters a window for large-scale explosive growth.
From an industry perspective, Winbot (窗宝) is leading window cleaning robots into a multi-billion yuan track, forcing the industry to shift from price involution of single products to high-quality competition focused on full-scenario capabilities, ecological systems, and technological barriers. Relying on the drive of two hit products and the advantages of a three-dimensional ecosystem, Ecovacs (科沃斯) continues to widen the gap with its pursuers, leaping from the leader of Chinese robot vacuums to a global leader in multi-category service robots, completely rewriting the original competitive landscape of household robots.
The success of Ecovacs (科沃斯) Window Robot is essentially a victory of "using technology to eliminate life's difficulties."
From the floor to the facade, from sweeping floors to cleaning windows, Ecovacs (科沃斯) has always anchored itself to the unchanging core of "making life simpler and safer." Its 15 years of deep cultivation prove that true growth is not about chasing trends, but waiting for the wind to come—discovering needs and accumulating over the long term; when the demand accumulates to the point where it "can't be hidden," the market will naturally provide the answer.
What Winbot (窗宝) has ignited is not just a multi-billion yuan track, but a systemic transformation of home robots from flat to three-dimensional, and from single products to ecosystems. It has provided a model of long-termism for the industry—responding to real life problems with innovation and leading the industry toward a broader future.
