Model overview based on user reviews  
The Karcher BP 3 Home & Garden surface pump is designed for handling clean water and offers a maximum performance of 3300 L/h with a maximum head of 40 meters. It operates with a centrifugal pump type and has a suction height of 8 meters. The pump is powered by an 800 W electric motor and is built with a plastic housing, ensuring a lightweight design at 10.3 kg. While the product specifications suggest reliability and efficiency, user reviews of a similar model, the Karcher BP 5 Home & Garden, indicate potential issues with the automation system, which may lead to unreliable performance and frequent errors. Despite its attractive design and power, the automation's inconsistency could be a concern for users seeking a hassle-free experience.

Nothing
The automation is not working properly. Pressure builds up, turns off, turns on again in 5 seconds, and so on in a loop, after several cycles it errors out randomly - sometimes it indicates an error on intake, sometimes on output... It varies...

Do not take!

I bought the second one in three years. Again the same rake. If you don't mind your nerves, then take it. Just an advertised brand. I bought a lot of different Karcher equipment for home - now I am a regular customer of the service center
Beautiful and powerful
Extremely capricious, unreliable automation
