Karcher's T200 Deck and Driveway Cleaner cleans a 12" wide area gently as it hovers, providing consistent, professional results. Cleaning a large area such as a deck with a regular spray wand can be time consuming and, if you're not very careful, may leave behind streaks due to the difficulty in keeping the nozzle at a consistent distance from the surface. The T200 eliminates streaks by keeping its two nozzles at a fixed height from the surface and, due to their high velocity spinning are with each pass. Remove the wand and the handle to clean garage doors, brick, siding and other vertical surfaces.
