Free filter 100% automatic The clogged filters are spent water, because the automatic cleaning of the main AUTOCLEAN (AC) filter keeps the filter free and guarantees a constant and high suction power. The CLEANTEC CTL 36 AC with 36 l of tank volume offers a lot of volume and flexibility thanks to the wide geometry of its tank. Equipped with adjustable steering wheels and rear wheels, it offers ideal mobility. It also has an immobilizer brake that guarantees a safe position on any surface and when transporting it. The flat filter integrated in the suction head allows you to take full advantage of the volume: the gross volume of the tank and the net are practically identical.
