About Lest C8 Purgator Vaporarius

Lest C8 est purgator vaporarius ad mundationem domesticam destinatus. Forma eius proprietates purgatorum aspirantium et vaporariorum coniungit, mobilitatem et tractationem ergonomicam cum efficacia vaporis in corpore compacto sociando. Rotae integratae et ansa tollendi motum et transportationem facilem sustinent. Moderatio vaporis multiplicium graduum per instrumentum tactile capacitivum constituitur, emissionem ad superficies diversas accommodans. Rostrum cum articulo flexibili accessum et commoditatem auget. Receptaculum aquae amovibile per operculum superius impletur. Mundatio sine substantiis chemicis perficitur.

Unique Properties: Lest C8 is a steam cleaner designed to be simple and intuitive to use yet stylish. It features multi-stage steam regulation to adapt output to different surfaces and dirt levels by a capacitive UI. The nozzle with flexible joint ensures excellent ergonomics and perfect cleaning results thanks to lamella technology. Cleaning is performed without chemicals and removes up to 99.999% of viruses and 99.99% of common household bacteria from hard surfaces.
Dimensions & Packaging: 220 x 295 x 115
Tags: steam, cleaner, floor
Production Technology: ABS injection molding
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.
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.
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.
