The B40 offers a previously unknown level of safety and protection whilst being simple to use and easy to turn.


Safety: a key function

The Kärcher Intelligent Key system (KIK), allows each operator to have their own customisable key, making operation of the machine significantly easier. Settings such as machine speed, detergent quantity, brush pressure and water quantity can be locked, allowing the operator to focus exclusively on cleaning.


Quiet, strong and efficient

Reduce power in eco!efficiency mode and thereby reduce the noise levels, these walk behind scrubber driers are also a good choice for noise sensitive work areas. For maintenance cleaning, it shines in every situation thanks to its efficiency and impressively long battery run time.



The fresh water tank can be quickly filled by connecting a hose to the machine and turning on the tap. The supply automatically stops when the tank is full, allowing the operator to get on with other work.


Simply always clean

The first machines to feature an integrated tank rinsing system. The dirty water tank can be quickly and automatically cleaned after operation by connecting a hose to the innovative nozzle system fitted in the lid. In this way, they support the HACCP concept and ensure hygiene and health protection in a simple way.
