In the run-up to the test, we defined practical requirements and the following test criteria:
- Cleaning performance
- Quality impression
In order to evaluate these criteria, we have defined several tests for the hand steam cleaners. In these tests, the appliances have to assert themselves in four different cleaning scenarios: freshening up clothes, cleaning joints in the kitchen, cleaning windows and removing a coffee/orange stain from a smooth surface. The best cleaning result is then assessed. During the test series, the handling and ergonomics of the appliances are assessed. The additional attachments included in the scope of delivery are also tested. However, a large number of attachments does not guarantee a better grade as long as the cleaning result is not satisfactory.
In order to rule out mistakes and to ensure the load of everyday use, each test takes place in several rounds.
The test criteria receive percentages depending on their importance. The final score is then objectively calculated from the test criteria using an algorithm.
Our product selection is based on an observation of the current market. In addition to popular branded products, we also include insider tips in our selection. Criteria such as price and range of functions are an important factor for us. The test field is also determined by analysis and evaluation of customer reviews and external tests (e.g. Stiftung Warentest).
The devices are purchased anonymously or lent to us by the manufacturer. Dealers and manufacturers have no influence on the tests and our evaluation.
As soon as new relevant products come onto the market, our test field is extended by these. The new products go through the same test as the already tested devices.
