On top of the brushes, warm water flows over the boards and brushes. This water is pumped around from an integrated electrically heated water reservoir, if desired a cleaning agent can be added.
The water supply and temperature are adjustable. It is possible to rinse the washed boards with fresh water. The brushes are mechanically adjustable to the correct thickness of the board. The shelf runs automatically through the machine with driven rollers. It is possible to have the plank make an in and out movement on the same side instead of passing it through the machine. The advantage is that the boards are cleaned better and that the machine can only be operated by one worker, but one-way traffic through the machine is also possible.
