I invested (investment considering the price we can talk ...) with the purchase of a used car while I hesitated to make cleaning inside by a PRO. The result is very satisfactory, brushes all have value and can treat all surfaces, rotating brush is perfect for carpets and seats, the wirehaired allows to fetch the persistent dirt clinging to the fabric and also allows aspire plastics without scratching. The telescopic nozzle goes everywhere even between the seats. This kit offers a significant time saving for a better result, my city and my wagon sedan are always spotless. When will a Dyson system for outdoor ;-)
