Superb
After years of just using the lance I bought this attachment. Should have done it earlier. What a time saver. Cleans the paving and the block paving very well using it on a K4. I didn’t have to wash the windows and doors afterwards!

Should have bought one years ago
Amazed at how much better this is at cleaning the patio. I always figured that this would never be as effective as the lance used directly – how wrong I was! On really stubborn bits I still use the lance to remove well attached moss and weeds, but the k7 is doing 95% of the work in a quarter of the time without the mess ( or back ache!)

Good for maintaining
Great purchase, keeps surrounding area from being sprayed. However it is nowhere near as good as the normal blast head for cleaning block paving, that said. For onward regular maintenance have initially use jet blaster it is wonderful.

Pulizia pavimenti esterni veloce e facile
Utilizzato per pulizia pavimenti esterni (porfido) si rivelato un ottimo prodotto abbonato ad idropulitrice Karker K7. Molto efficace anche ugelli anteriore per risciacquo pavimento dopo pulizia con testina rotante. Rispetto alla pulizia con normale lancia si ottimizza il tempo, si riducono gli sprechi e si riduce lo sporco spruzzato in giro. Soddisfatto dell’acquisto, nonostante il costo.

More speed, less mess
I’ve got an older model K4, this worked so much better than just the lance for cleaning the drive and patio.
I had to change the inserts, which come in the box and is just a simple case of removing the cotter pins and swapping them out on the end of the rotating bar and is easy to do, takes 30 seconds.
This is the first deck cleaner I’ve had so i can’t compare to any other model, however, I can say that this model makes cleaning so much faster and far less messy. I cleaned my drive & patio and also my mom’s patio (which is a decent size) in the same time it used to take just to clean my drive with the lance alone.
The foot button on top that turns it into a sweeper is priceless and works really well. The corner jet, which is another button on the top, works ok but the lance does a better job imho.
I figured out that the best method is a bit like painting a room, cut the edges first and then zip over the main area with deck cleaner attachment – which flies over a large area really quickly, and you don’t need to go slow, it lifts the dirt off really well with a moderate pace pulling it over the surface.
If I had to be picky, I’d say Karcher should abandon the corner jet and sell the item cheaper with the saving, as it isn’t that useful. Where I was surprised was the double extension pieces, which I thought would be awkward and wobbly, but they actually work great and I found that using one of the extension pieces makes using the lance 100% easier, I couldn’t believe the difference! Everything else is just brilliantly better. Clean up is a delight – and wiping down doors and windows afterwards almost goes away, which is the bit I hate 🙂

Gut durchdach
War vor dem Kauf skeptisch, ob so eine Reinigungsbrste etwas taugt.

Nun bin ich positiv berrascht. Man kann damit Bodenplatten oder die Dielen auf der Terrasse reinigen, ohne da alles an die Wnde spritzt.

Zunchst lt sich das Gert ber den Austausch der Rotationsdsen an unterschiedliche Hochdruckreiniger-Modelle anpassen. Bei geringerem Druck (kleineres Gert) tauscht man die Dsen gegen die mitgelieferten anderen Dsen aus.

Dann kann man die Reinigungsbrste problemlos an den Hochdruckreiniger anschlieen und los geht’s.
Die Reinigungsstrke lt sich mit einem Drehregler in einigen Stufen verstellen. Auerdem sind oben mehrere Knpfe drauf, so da man mit dem Fu zwischen verschiedenen Reinigungsarten whlen kann. Bei mir hat es sich bewhrt, die grobe Verschmutzung mit dem Rotationssystem zu entfernen und dann auf den breiten Frontstrahl umzuschalten, um die Reinigungsrckstnde wie mit einem breiten Besen von der Flche zu “kehren”.

Alles sehr gut durchdacht – wie man es von Krcher kennt.

Den Punktabzug gebe ich, weil man nicht ganz bis in die Ecken kommt.
