A Kärcher K2 series comes in different shapes and sizes. This series of starter high-pressure cleaners is ideal for a wide range of cleaning jobs. You can use a Kärcher K2 high-pressure cleaner with a lower operating pressure for the occasional cleaning job, such as cleaning your bike or garden furniture. Purchase a patio cleaner to clean patios of up to 25m². If your patio is larger, the Kärcher K2 isn't the right model for you. This series isn't suitable for more demanding jobs, such as cleaning a large car or tractor.
