In the run-up to the test, we defined practice-oriented requirements and the following test criteria:
- Cleaning result
In order to evaluate these criteria, we have defined several tests for cordless vacuum cleaners. In these, the devices vacuum sawdust from smooth and carpet floors. They also have to clean edges.
Carpets and smooth floors must be cleaned in the test.
The cleaning result is documented in before-and-after pictures. The handling, ergonomics, and volume of the products are checked during the vacuuming process. We also check the vacuum cleaners for additional functions and attachments. Finally, the batteries of all vacuum cleaners are discharged in the endurance test and then recharged.
In order to rule out errors and to ensure the strain of everyday use, each test takes place in several stages.
The test criteria are weighted according to 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.
