Kärcher High Pressure Washers HD 9/20-4 SXA Plus
Couldn't load pickup availability
The HD 9/20-4 SXA Plus cold water high-pressure cleaner offers both power and convenience. The equipment includes high-quality materials, the automatic hose reel and the rotating Vibrasoft nozzle.
The HD 9/20-4 SXA Plus cold water high-pressure cleaner makes ergonomic work possible thanks to the EASY!Force Advanced high-pressure gun without holding force. The pressure and water volume can be regulated directly on the gun/lance with the Servo Control control unit; the stainless steel lance (1050 mm) can be rotated. The Vibrasoft rotary nozzle reduces vibrations and noise by up to 30 percent. The cleaner impresses with its high-quality workmanship and materials: the vertically installed motor and pump unit (upright concept) consists of a wobble pump with stainless steel pistons and brass cylinder head as well as a 4-pole low-speed motor with air-water cooling system and a compact design for maximum portability. The aluminum frame makes the chassis robust, lightweight and suitable for crane loading. Includes Ultra Guard high-pressure hose with durable Teflon® coating and an automatic hose reel that can be rolled up and unrolled even under pressure and at an angle of up to 45°, for up to 50 percent faster set-up times. This super-class unit is rounded off with accessory storage options such as a storage compartment and adjustable hooks.
