K1700 Cube vs K5 FC Specs
Maximum Pressure
The Kärcher K 5 FC delivers 2000 PSI of cleaning power, while the K1700 Cube Black provides 1700 PSI. This 300 PSI difference means the K 5 FC has more force to blast away stubborn grime, old paint, or deep-set stains on driveways. The K1700 Cube is sufficient for lighter tasks like patio furniture or car washing. If you need extra power for tough jobs, the higher pressure rating of the K 5 FC is a clear advantage.
Flow Rate
Both pressure washers share an identical 1.2 GPM flow rate. This means water volume is the same for both units, allowing similar rinsing speeds and detergent application rates. Since the flow rate matches, neither model has an advantage in terms of how quickly it can flush away loosened dirt. You will get consistent water coverage regardless of which machine you choose, making this a neutral factor in your decision.
Pump Construction
The K 5 FC features a heavy-duty aluminum pump, described as professional-grade and designed for longevity. In contrast, the K1700 Cube does not specify its pump material in the provided data. Aluminum pumps generally handle higher pressures and frequent use better than plastic alternatives. If you plan to use the machine often or for demanding projects, the aluminum construction of the K 5 FC offers better durability and resistance to wear.
Dimensions and Weight
The K1700 Cube Black is significantly more compact, measuring 16 inches in length and 18.5 pounds in weight. The K 5 FC is taller at 33.4 inches and lacks a listed weight. The cube shape of the K1700 makes it easier to store in tight spaces and carry around. If storage space is limited or you need a lightweight unit for quick trips, the K1700 Cube is the more portable choice.
Included Nozzles
The K1700 Cube includes three nozzles: 15°, turbo, and 65°. The K 5 FC comes with a foam cannon, a turbo nozzle, and 25° and 40° nozzles. The K 5 FC provides more versatility with the foam cannon for soft washing and a wider range of spray angles. The K1700 Cube offers a 15° nozzle for concentrated cleaning. The K 5 FC has a slight edge due to the inclusion of the foam cannon and additional spray patterns.
