Karcher T350 surface cleaner I already owned a Karcher power washer, but needed something to cleaning driveways and sidewalks. I purchased the T350 and used it for the first time yesterday. It worked like a charm, cleaned the areas easily and quickly. Already did my deck with just the power washer, so need to wait until next year to see how the surface cleaner works on that as well. I cleaned about 500sqft of driveway in about 20 minutes. I'm sure just using the powerwasher wand itself would have taken a few hours..
K 12 Surface Cleaner ONLY fits ELECTRIC Pressure Washers This attachment does not fit my Karcher K 2400 HH Gasoline Engine Pressure Washer. The factory rep advised that this attachment is ONLY for Electric Powered Washers at 2300 psi and below. You CAN NOT get an adaptor to use it with Gasoline Powered Washers. I wish Amazon would report that in the description. It sounds like a good attachment if you can use it.
Karcher K12 I used the Karcher surface to clean off years of grime from our patio, porch, and sidewalk. The concrete looks so much cleaner and brighter. It enables one to cover a larger area in less time,than if you used just the wand spray. I am glad I purchased it.
Adaptability I take back all that I said. It does fit the K2-45 and it works extremely well. I just haven't figured out the technique for vertical surfaces. This is a very satisfied customer. I needed to re rate it to a 4.
