The carpets, about 10 according to their size, are put in the washtub, where a 10-to-30-minute prewash is made using a detergent specially developed for this way of washing. Thanks to the air-bubbles put in the water and to the blades of slow turn, the machine makes currents which provide a soft rinsing to the fibre and which make it possible for the dirty particles to detach from both sides of the carpets. The machine prewashes and removes dust from the carpet and afterwards it is only necessary to give the carpet a quick check with the brush. The machine has been designed to put the carpet into and out of the washtub easily. It has been made of stainless steel. The washtub can be filled up and emptied quickly. Clamps are not required. Optionally it has a temperature control, which warms the water, until it reaches the required temperature.    Size: 4.10 m. long x 1.60 m. wide.    Weight: about 1.000 Kg.    Engine: triphase.    Power: 3 KW., 16 amp., 380 v.
