Enhance your outdoor cleaning experience

To enhance your outdoor cleaning experience, consider pairing your Karcher power washer with the Karcher T5 Surface Cleaner and Karcher TLA4 Telescopic Spray Lance, both designed to make large and difficult areas easier to tackle.

The Karcher T5 Surface Cleaner is the perfect tool for cleaning large outside areas quickly and efficiently.

Its twin-jet rotating arm covers a wider area compared to traditional spray lances, reducing cleaning time by half.

The adjustable nozzle height ensures it works on both sensitive surfaces, like wood, and tough materials, such as stone and concrete.

The splash guard provides a cleaner experience by preventing water from spraying everywhere, while the “hovercraft effect” makes it easier to manoeuvre, even on vertical surfaces like garage doors and building facades.

It’s ideal for patios, driveways, paths, and garden walls, ensuring that you can tackle both large and delicate outdoor cleaning tasks without hassle.

For cleaning hard-to-reach areas, the Karcher TLA4 Telescopic Spray Lance extends between 1.20 and 3.70 metres, allowing you to clean areas as high as 5 metres with ease.

The 180° adjustable hinge lets you target slanted roofs, conservatories, and carports.

Its simple telescopic mechanism, controlled at the touch of a button, makes it user-friendly, while compatibility with a wide range of Karcher machines ensures versatility.

This lance is particularly beneficial for those who need to clean higher surfaces like walls or tall facades without needing a ladder.

Both accessories are designed to complement your Karcher power washer, enhancing its capabilities for both everyday cleaning and more demanding tasks.
