Spray power & versatility
Discover a wide range of pressure washers with attachments to suit any cleaning task. With working pressures from 1160 PSI to 3335 PSI, our models cover everything from light car washing to deep cleaning like decks, paving, and machinery. Lower-pressure pressure washers are ideal for home and garden use, while our most powerful commercial petrol cleaner delivers professional-grade performance for heavy-duty jobs.
Different spray patterns and nozzles make it easy to tackle a variety of tasks. A wide fan spray gives gentle coverage for vehicles or patio furniture, while a narrow jet removes stubborn grime from concrete ground or tiles. Some pressure washer kits include extra accessories such as nozzles, brushes, or detergent bottles. You can also purchase Karcher cleaning attachments separately.
Installation, care & maintenance tips
Setting up your water blaster is simple. Most models are plug-and-play, so you can get started right away. Just connect the hose, turn on the tap, attach your chosen nozzle, and you’re ready to clean.
Maintain your machine by rinsing and draining the system after each use to remove dirt, detergent, and residual water that could cause buildup or corrosion.
Always store your pressure washer in a shaded, dry location, away from direct sunlight or moisture, to protect seals and electrical components. Regular care ensures smooth pump operation, consistent water pressure, and a longer lifespan for your equipment.
