Alright sure.. here are the Details.
Its Karcher (Made by Germany) and that is why its price is high than Black & Decker (Made in China). This one is for Rs. 14,000 whereas B & D for Rs. 12000
My Karcher is in 10/10 condition, as i hardly used it for maximum 4-5 times. Still under 7-8 months warranty :).

Well both Karcher and B&D are good, just some built quality difference and that is why the Price is bit high of Karcher. So your choice to pick Karcher or B&D 
My Full n final Price is Rs. 10,000 as new is for 14,000.
