## Long description

The Compression garden sprayer Kärcher PSU 4-18 4L Battery 18V is a battery-powered plant sprayer designed for efficient application of water, liquid fertilisers, pesticides and weed control treatments in small to medium garden areas. The unit combines a 4-litre translucent tank with an 18 V lithium-ion drive to deliver consistent pressure without manual pumping. Its compact dimensions (182 mm width × 750 mm depth × 365 mm height) and removable extendable lance support ergonomic operation and space-saving storage.
Advantages
The integrated electric pump activates with a single button press and eliminates the need for manual pumping, providing continuous, even pressure during application. The nozzle allows stepless adjustment between a fine mist and a concentrated jet and the lance trigger supports momentary or continuous spraying. A shoulder strap improves portability and one-handed operation. The tank includes a built-in fill level indicator and the wide screw cap doubles as a measuring cup for precise mixing.
Suitable for
Applying liquid fertilisers and plant nutrients
Targeted pest control and pesticide application
Weed treatment in borders and between paving
Watering seedlings, hanging baskets and small containers
General garden maintenance and spot treatments
Key specifications
Tank capacity: 4 litres
Power source: 18 V lithium-ion battery
Spray types: adjustable from fine mist to point jet
Lance length: extendable to 75 cm; removable for storage
Controls: on/off pump button and trigger for momentary/continuous spray
Portability: shoulder strap for comfortable carrying
Fill indication: integrated tank level indicator
Container cap: multifunctional screw cap that serves as a measuring cup
How to use
Fill the tank with the required liquid, using the cap as a measuring cup to ensure correct dilution. Secure the cap and switch on the pump with the main button; pressure builds automatically without manual pumping. Select the spray type by rotating the nozzle from a fine mist to a concentrated jet and use the lance trigger for momentary or continuous spraying as needed. Extend the lance for work at a distance or remove and clip it to the battery insert for compact storage. Recharge the 18 V battery according to the manufacturer’s instructions before longer jobs.
Usage recommendations
Wear appropriate personal protective equipment when applying pesticides or concentrated fertilisers. Rinse the tank thoroughly after use and store the device and battery in a dry, frost-free location. For even coverage, maintain a consistent walking pace and nozzle distance from plant surfaces; adjust spray pattern to the task—fine mist for foliar feeding and a narrower jet for targeted spot treatments.
