科沃斯窗宝 W3 深度测评：卖点变槽点，口碑两极反转

Core Viewpoint - Ecovacs, a leading brand in the home service robot sector, has long held a significant market share in the domestic window-cleaning and floor-cleaning robot markets, promoting the slogan "Technology liberates hands" [1][21]. Product Launch and Initial Reception - In early 2026, Ecovacs launched the Window Cleaning Robot W3, marketed as the "world's first fully automatic cloth-washing window-cleaning robot," which initially garnered considerable consumer interest and was seen as a benchmark for high-end window-cleaning robots [3][24]. - However, as user experiences began to surface, the actual performance of the W3 was found to be starkly different from its promotional claims [3][24]. Product Features and User Feedback - The W3 was designed with three main selling points: "fully automatic cleaning, no hand-washing of cloths, and efficient window cleaning," priced at 2999 yuan, targeting the mid-to-high-end market. Yet, user feedback indicated a significant disconnect between the product's performance and its marketing, leading many to label it as a "smart tax" [4][25]. - Key areas of negative feedback included the design of the machine, core functionality, and ease of use [4][25]. Design and Usability Issues - Users reported that the W3's weight and storage design contradicted Ecovacs' claims of "convenient operation." Weighing over 22 pounds without water, the W3 was significantly heavier than its predecessor, the W2S. Its separate design from the base station made it cumbersome to transport, particularly for elderly and female users, leading to many stating they only used it once before it was set aside [7][28]. - Additionally, the W3's anti-fall hook design was criticized for being too small, making it difficult to secure on smooth surfaces, which required users to spend excessive time adjusting it [9][30]. Core Functionality and Quality Issues - The stability of the window-cleaning effect is a critical factor for users, yet the W3 frequently failed in this regard. Reports indicated that users experienced severe noise, malfunctioning spray functions, and other quality issues shortly after purchase, leading to an inability to use the product effectively. Complaints about slow after-sales service further exacerbated consumer losses [12][33]. - The issues with the W3 were not isolated; a review of complaints across various platforms revealed that Ecovacs' other products, including floor-cleaning and air-purifying robots, also faced numerous quality complaints, indicating systemic problems in product development, quality control, and after-sales service [16][37]. Broader Implications - The recurring quality issues across Ecovacs' product lines suggest significant shortcomings in their overall product development and customer service processes, which could impact the company's reputation and market position in the competitive home service robot industry [16][37].
