as it is early days I cannot give a reliability rating,but I can say that so far I am pleased with the results I am getting.We live in an old house with pipes showing that collect dust and grime but now I am able to blast under,behind, and into all these difficult places. what a difference this makes to the overall look of the place.I would certainly recommend this product ,don't hesitate any longer, make cleaning more of a pleasure.
Don't hesitate to buy this amazing piece of equipment, versatile , easy to use and makes my life so much easier....cleaning anyway!
Thanks karcher great product and quality !
