With a Kärcher cordless construction vacuum, you can clean anywhere. In places without a socket, you can still vacuum dry, wet, coarse, and fine dirt. That way, you can easily use the construction vacuum in the garden or at a construction site without any hassle with cables. The battery of the construction vacuum is part of the Kärcher 18V battery platform. That's useful as this means that you can use the construction vacuum battery on other (garden) tools from Kärcher with the same voltage. This means you only need 1 battery for all your Kärcher devices.
