Steam-cleaning product technology

LEST develops steam-cleaning systems around efficient energy conversion, intelligent temperature control, adjustable output and practical accessory compatibility. The goal is to help users match steam performance to different cleaning tasks while keeping operation clear and convenient.

Fast heating

The 2026 catalog lists an approximately 15-second preheat time across the H1A and C-series models shown in the range.

Steam control

Depending on the model, control options include mechanical adjustment, touch control, handle-mounted adjustment and real-time temperature display. C1, C1T, C2A, C3 and C4A use three-level control configurations, while C2 and C4 provide six-level adjustment.

Capacity and pressure

Catalog models range from the 360 ml H1A handheld system to 1,250-1,600 ml C1/C2 platforms and 1,800 ml C3/C4 platforms. The listed maximum steam pressure is 4 bar.

Accessory platform

Compatible configurations can include crevice tools, scrapers, glass tools, brass and nylon brushes, microfiber covers, extension tools, sealing rings, cleaning pins and optional floor-mop kits. Confirm the included set and model compatibility before ordering.
