Frequently asked questions

Where do the scores come from?

From published tests by consumer organisations, labs and specialist publications. Every product lists each source with its country, issue and original verdict, with a link where possible. We run no tests of our own.

Why do some sources say “zitiert nach” (cited from)?

Some organisations, such as Stiftung Warentest, publish their detailed results only behind a paywall. In those cases we take the overall verdict from a freely accessible report that states the grade and issue, and we name that report.

Was exactly this model tested?

Manufacturers often sell the same appliance under different model numbers or with different accessories in each country. We group variants of one model line and name the tested variant next to the test when the source states it.

Why do the verdicts differ?

Test programmes differ: labs measure things like dust pickup or durability in endurance runs, while editorial reviews weigh everyday impressions more heavily. We do not smooth over such differences; the spread chart shows them.
