It includes a 3-in-1 Multijet lance that can be adjusted between vario lance, dirt blaster and detergent application settings. The pressure for each setting or the detergent dosage is easy to regulate with the simple buttons and LED display on our touch control trigger gun, and the hose is stored on a handy reel, with on-board storage for all other tools. The Plug and Clean detergent system makes applying detergent mess-free and easy. This model also includes a Home Kit, with a T450 Patio Cleaner for hard surfaces like decks and patios.There's also an 10m high pressure hose to give you plenty of reach, and a state-of-the-art long-life water-cooled motor that gives extra durability and outstanding performance. The Kärcher T450 can ensure you get the best results in less time and is five times faster than using a spray lance alone. You can also achieve better results with less effort and create less peripheral splash with this attachment; making clean-up tasks faster and easier thanks to the twin-jet rotating arms that effectively remove stubborn dirt while the cleaner directs the pressurised spray exactly where you want it to go. The T450 has corners & edges cleaning facility. A special protection grid helps you clean surfaces like gravel paths without disturbing stone chips. The water pressure can be adjusted by setting the nozzle clearance for the surface being cleaned.
