How does a steam cleaner work? [Explained simply]

Have you ever wondered how a steam cleaner can actually clean without any detergent? It almost sounds too good to be true – but the secret lies in the way steam works. In this article, you will get a simple explanation of how a steam cleaner works and why the Rennoa™ SteamCleaner can be a game changer in your cleaning.

What is a steam cleaner?

A steam cleaner is a cleaning device that uses regular water that is heated to produce steam. The steam is released under pressure through a nozzle and loosens dirt, grease and bacteria – without the use of chemicals.

With a steam cleaner you therefore get a combination of effective cleaning, a healthier indoor climate and a more environmentally friendly solution. Rennoa™ SteamCleaner is developed for exactly this: high efficiency, fast heating and strong, constant steam pressure.

How does a steam cleaner work?

The principle is always the same – regardless of model – but Rennoa™ SteamCleaner is designed to make the process even faster and more user-friendly.

A steam cleaner works in three simple steps:

  1. Fill the tank with water
    Water is poured into the machine's tank. On the Rennoa™ SteamCleaner, the tank is large enough for longer cleaning sessions, but still easy to handle.
  2. The water is heated
    The water is heated to approximately 100 °C, turning it into steam. While many machines take 20–30 seconds to do this, the Rennoa™ SteamCleaner is ready in just 15 seconds .

The steam is released under pressure When you pull the trigger, the hot steam is released. Rennoa™ SteamCleaner delivers a constant steam pressure of up to 4 bar , making it easy to loosen dirt in cracks, joints and textiles.

Benefits of a steam cleaner

In many cases, a steam cleaner can completely replace cleaning agents – and give you a cleaner home in less time.

The biggest advantages:

  • No chemicals – you clean with only water
  • Effective disinfection – the heat kills bacteria, mold and dust mites
  • Versatile cleaning – can be used throughout the home and car
  • Environmentally friendly – ​​fewer spray bottles, less plastic and better indoor climate

How to get the most out of your steam cleaner

If you want the best result, there are some good tips to follow:

  • Use distilled water if you live in an area with a lot of lime.
  • Start with low steam pressure on sensitive materials
  • Wipe with a microfiber cloth once the dirt has dissolved.
  • Clean the nozzles regularly for optimal performance.
  • Always test on a small area first if in doubt.

With the Rennoa™ SteamCleaner you get six different steam levels, so you can easily adjust the pressure for both delicate and more demanding tasks.

Is a steam cleaner better than traditional cleaning?

In many cases, yes. Steam penetrates deeper into cracks and pores than a cloth or mop, and can thus remove dirt that would otherwise be stuck. At the same time, you can avoid using chemical cleaning agents altogether.

Rennoa™ SteamCleaner is a good example of how a modern steam cleaner can give you faster, cleaner and healthier results – without extra products in your cleaning cabinet.

Conclusion and next steps

A steam cleaner is an effective and environmentally friendly alternative to traditional cleaning. It uses only water, but can still dissolve dirt, remove limescale and kill bacteria. The Rennoa™ SteamCleaner makes it even easier: Ready in 15 seconds, six steam levels and constant steam at 100 °C.
