QV4 Steam Cleaner – Compact, Powerful & Continuous Steam Cleaning

Powerful Steam Cleaning for Superior Hygiene

The QV4 Steam Cleaner is a compact, yet powerful steam generator designed to deliver exceptional cleaning and sanitising performance. Using high-temperature steam, the QV4 effectively removes dirt, grease, bacteria, and odours while significantly reducing the need for chemicals, detergents, and excessive water consumption. It's the ideal solution for users looking for an environmentally friendly and economical cleaning system.

Continuous Steam with Non-Stop Technology

The QV4 features an advanced 1.5-litre boiler powered by a 2200W heating element, producing an impressive 4.5 bar of steam pressure for fast and effective cleaning.

Its innovative Non-Stop System allows the boiler to be refilled without switching the machine off, providing continuous steam generation for uninterrupted cleaning. This means less downtime and greater productivity, whether you're cleaning kitchens, bathrooms, floors, upholstery, or other hard surfaces.

Ready to Clean in Minutes

Thanks to the convenient Click&Go System, the QV4 heats up quickly and is ready for use within minutes. Spend less time waiting and more time cleaning with a machine designed for efficiency.

Adjustable Steam Control

Every cleaning task requires a different level of steam. The QV4's exclusive Flow-Master Technology gives you complete control over steam output, allowing you to easily increase or decrease the steam flow depending on the surface being cleaned. This provides excellent versatility for delicate materials as well as heavily soiled areas.

Built-In Safety Features

Safety is a key feature of the QV4. The intelligent Intelli-Boiler System continuously monitors the machine and automatically shuts it down in the event of an abnormal operating condition, helping to protect both the user and the machine.
A built-in pressure gauge and clear indicator lights on the control panel provide real-time information on the machine's operating status, giving you complete confidence during use.

Lightweight, Compact & Easy to Use

Constructed from durable ABS housing, the QV4 is the lightest and most compact steam generator in the STI range. Its lightweight design makes it easy to transport, store, and manoeuvre, making it ideal for both domestic users and light commercial cleaning applications.
