The Dirtblaster is a spray cleaning lance attachment for Karcher home pressure washers from the range K1 to K7. It channels the water from the washer into an even more highly pressured spray and is ideal for cleaning patios and for removing moss from garden paths, according to Karcher. If a problem occurs, it may have a simple solution and it is always worth troubleshooting the device yourself before making a potentially expensive service call.
