The "tank" sweeping robot built for overseas markets takes 30mm super barrier-surpassing performance as the core breakthrough point, and responds to the core demands of overseas users for "strong passability, high practicability and excellent experience" of cleaning equipment with accurate design language. From performance architecture to detailed technology, each design is deeply in line with the use scenarios and aesthetic preferences of overseas families. The naming of "tank" is not a simple conceptual packaging, but an intuitive interpretation of the hard core performance of the product-the obstacle crossing height of 30mm accurately hits the common obstacle pain points such as threshold stones and carpet edges in overseas families, far exceeding the average level of 20-25mm for low-end models in the industry, and becomes the core differentiation label for products to enter overseas markets. In order to achieve this key performance, the design team adopted a large-angle tilt structure of the front and rear fuselage, and reduced the resistance and hook risk during climbing by optimizing the contact path between the fuselage and obstacles, providing core support at the structural level for obstacle crossing.
The landing of obstacle-crossing performance is not a breakthrough of a single structure, but the result of multi-system collaboration. Different from the single or two-stage power layout of the traditional sweeping robot, the "tank" innovatively adopts the front, middle and rear three-stage power design. The front and rear wheels and the middle traveling wheels have independent driving forces, forming an all-round power output system. When encountering an obstacle with a height of 30mm, the front wheel takes the lead in pulling the fuselage up, the middle wheel provides stable support, and the rear wheel synchronously boosts to avoid the fuselage getting stuck or slipping. The three form a joint force, making the obstacle crossing process smoother and more efficient, completely solving the user pain point of "top death and stuck" of traditional models at high threshold, and making the strong passability of "tank" not only stay at the parameter level, more translated into a reliable experience in real use.
In the balance between obstacle avoidance and space utilization, the design team showed unique wisdom. Relying on the mature 360-degree all-round obstacle avoidance technology, there is no need to pursue redundant full-view coverage, but the 220-degree core radar viewing angle is accurately retained, which is sufficient to meet the core requirements of map building and obstacle avoidance, avoiding waste of computing power and reserving space for fuselage structure optimization. Based on this design trade-off, the lower part of the fuselage is made into a sliding back shape. This seemingly pure form design is actually the ultimate use of space-the sliding back structure cleverly revitalized the easily wasted lower space in traditional models, successfully accommodated large-capacity water tanks, and greatly improved the cleaning endurance, achieve the "functional requirements" and "space utilization" of the perfect fit.
Base station design is also based on the actual use of overseas users as the starting point, showing human considerations. After repeated research, the choice of square shape fits the storage space such as cabinet bottom and low cabinet common in overseas families, without occupying additional ground area and easily integrating into the home environment. The dust box warehouse adopts a front drawer design, which completely changes the inconvenience that the traditional base station needs to drag and drop to replace the dust box. Users can easily pull and pull when standing, especially for overseas elderly users or groups pursuing convenient experience, and "ease of use" runs through every detail of use.
The polishing of the shape and process makes the product more attractive in the market beyond the performance. "Tank" adopts a soft mecha style, abandoning the cold feeling of pure mecha design. Through the design language of reducing the surface, while retaining the product's tough performance and temperament, it also adds the softness of home adaptation, which can not only show the strength of "tank", but also not conflict with modern home style. Technically, the product does not use a complex secondary process, but through the bright matte surface material comparison, naturally presents a delicate texture, which not only reduces the environmental risks and costs of the production process, but also meets the EU RoHS and other overseas compliance certification requirements. At the same time, the design team strictly controls the size of the injection base of each injection molded part to ensure smooth appearance, effectively reduce the defective rate, and provide convenience for large-scale production while ensuring product texture.
From the structural innovation of core performance to the polishing of details of user experience, from the precise positioning of modeling style to the optimal balance of process costs, every design of the "tank" sweeping robot revolves around the pain points of overseas market demand. It is not only a cleaning equipment with 30mm obstacle crossing ability, but also a home solution integrating performance, practicality, beauty and convenience. It uses the power of design to break the inherent cognition of "weak obstacle crossing and poor experience" of sweeping robots in overseas markets, bringing more efficient and worry-free cleaning experience to overseas users, It also lays a solid foundation for the competition of products in overseas markets.
