Nicola Zanetti and Federico Bosque · CLIENT: Lest
Lest C8 is a steam cleaner designed for domestic cleaning. The design combines features of vacuum cleaners and steam cleaners, joining mobility and ergonomic handling with steam performance in a compact body. Integrated wheels and a lifting handle support easy movement and transport. Multi-stage steam regulation is set through a capacitive touch interface, adapting output to different surfaces. A nozzle with a flexible joint improves reach and comfort. The removable water tank is filled from the top lid. Cleaning is carried out without chemicals.

- Design Challenge
- This steam cleaner explores the convergence between vacuum cleaners and steam cleaners, redefining usability through a hybrid typology. The design research focused on mobility, ergonomics, and product perception, introducing integrated wheels and a lifting handle to enhance maneuverability and transport. Benchmark analysis highlighted gaps between bulky steam systems and agile vacuum cleaners, guiding a compact, balanced architecture. Prototyping and 3D validation refined proportions and user interaction, resulting in an intuitive, domestic-friendly steam cleaner that bridges two established product categories.
- Project Duration
- June 2025 to december 2025 Italy and China
- Operation Flow
- refill the removable water tank on the bottom from the top lid, set temperature by the touch UI, clean with steam.
- Research
- The creative challenge was to achieve high ergonomic performance despite the product’s compact dimensions. Design research focused on simplifying the user interface to ensure immediate, intuitive interaction, reducing visual and functional complexity. At the same time, the project aimed to maintain a clean, essential design language while conveying a modern, refined, and well-equipped character. Careful proportioning, surface continuity, and functional integration allowed the steam cleaner to appear visually light yet technically complete, balancing clarity, usability, and contemporary aesthetic appeal within a reduced footprint.
- Inspiration
- The design inspiration comes from both vacuum cleaners and steam cleaners, combining the best qualities of each category. From vacuum cleaners, the project adopts mobility, compactness, and ergonomic handling; from steam cleaners, it integrates effective cleaning performance and functional robustness. The creative intent was to merge these strengths into a single, coherent product that is visually appealing, simple to understand, and highly functional.
