Compact and lightweight
Bought as I wanted a small washer to wash the cars rather than get the big powerful AVA out. This unit is compact and comes with decent attachments but the hose is terrible it coils up like a snake so replaced with a slightly longer better quality one now much better and can reach all round the cars. The washer is slightly quieter than most at 80db and the pressure is good for it’s size. Register your guarantee and you get 5yr cover with Karcher just hope I don’t need to use it.

Great accessories
Great equipment, light weight, very happy with the noice reduction as well as the portability. All the accessories are very useful and helpful. My only negative comment is that the pipe length could have been longer.

Powerful and Quiet
Super little unit. It's compact and easy to store. Light enough to move around without effort yet it's really stable in use. There's more than enough power for cleaning the car, drive, garage door, etc. Coupled with a foam cannon car cleaning is a cinch. There's also the advantage that this thing is quiet. It's not silent but compared to a regular pressure washer it's significantly quieter. You really don't game too worry about driving the neighbours wild when using it.

Good things come in small packages!
I’ve had a K7 pro but it’s such a chore unwinding the hose (hate it) that I never use it for washing the cars as much as I’d like to, although it’s a fabulous bit of kit. I came across the K Silent Anniversary purely by chance and decided to to give it a try because the simplicity and portability really appealed to me. And I wasn’t disappointed; it’s perfect for cleaning my car collection, it’s easy to move around. Just enough power to do the job, quiet enough not to be an annoyance, a generous assortment of accessories; and most importantly, a user friendly hose that isn’t a pig to unwind and put away. I’m a fan, enough said.

Perfect lightweight car washer
Had Karchers in the past that were much more powerful but I mainly use to wash the car and for that its perfect. Much quieter meaning I can wash the car early on a weekend without disturbing my neighbours. Extremely light and easy to move. Comes with everything you need including the snowflakes bottle and I got it in the sale. Would certainly recommend.

Great Tool
Only used once but I was very impressed not only by the difference in noise but in its power, pressure efficiency and the range of tools & accessories included.

Great Price
I bought this on the 30th October 2025 but didn't open the box till end of November to wash the patio ready for the winter months ahead of us. I was very pleased with the quality of the equipment and after reading the instructions how easy it was to put it together. The power, pressure and portability are excellent. The noise level is vastly improved, I only used the one nozzle but that was excellent as well.

Hello Aidan,
The supplier has advised the following for the Karcher K Silent Anniversary Edition Pressure Washer - 1800W:
“ The official sound power level of the Karcher K Silent Anniversary is 80 dB(A).
Sound pressure level LpA dB(A) 64
Uncertainty KpA dB(A) 3
Sound power level LWA + uncertainty KWA dB(A) 80
To provide some context, this noise level is comparable to a loud vacuum cleaner or the sound of a busy street with traffic. It is significantly quieter than many standard pressure washers, which can be in the 90-100 dB(A) range, similar to a lawnmower or a motorcycle.
The "Silent" technology in this machine uses special foam materials and optimised air circulation to effectively dampen the noise, making it ideal for use in residential areas where you may be concerned about disturbing neighbours. ”
Thanks for using Q & A.
