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

Fast and efficient – ​​Rennoa™ SteamCleaner is ready in just 15 seconds and works with constant steam at 100°C

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.
