After eight years, the "Five Friends" test format is now retiring. There is a new, exciting concept for 2026. For once, the five products tested have no common denominator. Or perhaps five "friends" that don't fit in anywhere? But that would be misleading, because they are all exciting products that have proven themselves.

When it comes to mobile cleaning appliances, a compromise often has to be made. Either they are large and bulky or they have a small water tank that doesn't reach very far. The KHB 6 from Kärcher is such a "middle ground", small and handy, but without a water tank. Thanks to its battery operation, it can be used flexibly and is easy to transport.

When you hear Kärcher, you immediately think of high-pressure cleaners. But Kärcher reverses this premise for a mobile outdoor cleaning device: The Mobile Outdoor Cleaner provides up to 15 minutes of cleaning time with a rechargeable battery and 4 liters of water, and the low pressure also ensures good cleaning performance thanks to a special nozzle.
