In the run-up to the test, we defined practical requirements and the following test criteria:
- Cleaning result
In order to evaluate these criteria, we have defined several tests for the hard floor cleaners. First, the scope of delivery and functions are checked. Before the tests are carried out, the equipment is prepared as recommended by the manufacturer. In order to put the cleaning power to the test, the equipment must remove liquids, damp dirt (a mixture of soil and water) and dried cola as well as coffee from laminate flooring. During the cleaning process, the handling is assessed and the volume of the instruments is measured. It is also checked whether the hard floor cleaners leave streaks behind. In further runs, we check the cleaning at corners and edges and the battery life. Finally, the cleaning effort of the rollers and the rest of the equipment is assessed.
In order to rule out errors and to ensure the load of everyday use, each test takes place in several runs.
The test criteria are given 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.
