The IB-600 Eco is the larger/heavier variant of the IB-500 Eco. This machine consists of a large, very robust dirt collector with a front-mounted brush roller of 60cm diameter. The brush used on this roller is of the best quality available in the market so it will achieve the best sweeping results. The height of the brush can be infinitely adjusted by 2 rotating spindles. The difference with the IB-500 Eco is that the diameter of the brush roller is even larger for an even longer life span and even more sweeping power. A second difference is that the roller is driven by a heavy duty motor that is concealed in the brush roller. The dirt collector is emptied by tipping the machine forward.
