                The Kärcher K4 is rated as delivering a maximum of 130 bar while the K7 offers a slightly better maximum of 180 bar, so if you're looking to really show the dirt who's boss, the K7 is the ultimate choice. Flow rate is a similar story: the K4 offers a maximum of 420 while the K7 offers a maximum of 550.Aug 23, 2022
