Karcher K1700 Cleaning Power (What to Expect)
Many people buy pressure washers thinking higher PSI means everything. But the real cleaning depends on:
1) Pressure
Pressure helps loosen stuck dirt.
2) Water Flow
Water flow washes the dirt away and speeds up cleaning.
3) Nozzle Pattern + Distance
Nozzle type decides how harsh or gentle the spray becomes.
The K1700 is designed for safe and practical home cleaning, not extreme heavy dirt removal.
