Karcher K1700 Vs K1800: An explanation of the key differences!

The main difference between the Karcher K1700 and K1800 is that the K1700 boasts a maximum pressure of 2125 PSI, outperforming the K1800, which provides a pressure of 1800 PSI. Despite having a lower PSI, the K1800 makes up for it with a longer hose length. Its hose extends 25 feet, compared to the K1700’s 20 feet hose, providing a wider cleaning range.

Pressure Power Difference:

The Karcher K1700 has a higher PSI rating than the K1800. This makes it more powerful and effective for tougher cleaning tasks like washing concrete, pavements, and stubborn grime on vehicles. The high pressure ensures more efficient water usage, delivering robust cleaning power that can tackle even the most challenging jobs.

Hose Length Difference:

While the K1700 has impressive power, the K1800 has a longer hose, which provides a greater cleaning radius. This allows for more flexibility, especially when cleaning larger areas like long driveways or big patios. The extra length can also make it easier to reach higher places, such as the second story of a house or the roof of an RV.

Motor Efficiency:

Another crucial difference lies in their motor type. The K1700 is powered by a brushless induction motor, which generally has a longer operational life and operates more quietly than a standard universal motor. The K1800, however, is powered by a universal motor.

Navigating the path of outdoor cleaning solutions, the comparison of Karcher K1700 vs K1800 exposes the excellence of these two models.
