## Long description

The Karcher K 5 Smart Control Flex eco!Booster (model 1.324-739.0) is a high-pressure washer for demanding home and light professional cleaning tasks. It combines an LCD-equipped Smart Control gun with adjustable pressure and detergent dosing, an eco!Booster mode to reduce water and energy consumption, and a flexible PremiumFlex high-pressure hose for easier maneuvering. The set includes a three-in-one Multi Jet rotary nozzle that offers three spray types and a Quick Connect fitting for simple attachment of the high-pressure hose and accessories.
Advantages
The unit offers precise pressure adjustment and on-gun detergent control via an LCD display and buttons, plus a Boost mode for extra cleaning power when removing stubborn dirt. The PremiumFlex hose improves mobility and resists kinking, while Bluetooth connectivity to the Kärcher Home & Garden app provides guidance on optimal water pressure and step-by-step cleaning support. Quick Connect and Plug 'n' Clean compatibility simplify accessory and detergent changes.
Suitable for
Cleaning patios, driveways and terraces
Washing cars, bicycles and garden machinery
Removing moss, algae and medium to heavy dirt from facades and fences
Regular maintenance of outdoor surfaces and equipment
When it may not be suitable
This pressure washer is designed for demanding household and light professional use; it may be more powerful and feature-rich than needed for occasional, very light cleaning tasks. For large industrial-scale cleaning or continuous heavy-duty use, a commercial-grade machine with higher continuous duty ratings may be more appropriate.
