Pressure & Power
The pressure and power of an electric power washer indicates how well it can accomplish your household tasks. All of these models have a TruPressure Certified PSI, which ensures that you’ll always receive the pressure promised. As indicated by their names, these models all have differing PSIs. The Karcher K2000 is the most powerful overall and has the most impressive amount of cleaning power.
There are other slight differences when it comes to the pressure and cleaning power of these models. The K1700 and K1800 boast 1.2 gallons per minute of pressure. These two models also have a universal motor. In comparison, the Karcher K1900 and K2000 have a slightly more impressive 1.3 gallons per minute of pressure and are powered instead by an induction motor.
While all of these appliances are plenty powerful, there is one that is clearly more impressive in this area than the rest. The K2000 model has a PSI of 2000 and 1.3 gallons per minute of pressure, all of which is due to the presence of a high-powered induction motor. It’s for these many reasons that the K2000 model is superior in this category.
Included attachments are extra features that help provide your home with a more thorough overall clean. The K1700 and K1800 models include a Plastic, Bayonet, and QC Spray Wands, which are sufficient in many ways. With that said, the K1900 and K2000 include Steel, M22, and QC Spray wands. The steel attachments are slightly more durable and sturdier than the plastic models, making these the more desirable attachments.
Nozzles are also great ways to customize your clean. Once again, there is a disparity between the nozzles included with these electric pressure washers. The K1700 and K1800 include a Turbo Nozzle that provides maximum cleaning power, a 15° Nozzle for all-purpose use, and a Detergent Nozzle that effectively distributes cleaning detergent. The K1900 and K2000 models include all of these same nozzles while also including an additional 40° Nozzle, allowing you more versatility and cleaning options.
While these differences are minimal, it is important to note that the K1800 and K1900 are also compatible with other industry-standard pressure washer accessories. The K2000 takes it a step further by also connecting with standard M22 hose connections and A3/4-inch connections. It’s for this reason that the K2000 has a slight edge over the other models, as it gives you more options when it comes to cleaning your home.
Detergent Tank Capacity
The tank capacity of your electric pressure washer is incredibly important, as a larger tank allows you to clean for longer periods of time without having to pause to refill. The K1700 and K1800 have a detergent tank with a half-gallon capacity. The K1900 model, however, has nearly twice the capacity by offering a 1-gallon detergent tank for added convenience.
The K2000 has a truly unique feature when it comes to the design and capacity of its detergent tanks. It instead features dual half-gallon detergent tanks that operate independently. While in use, users can simply switch which tank is in use via a convenient selector knob. This allows you to utilize different detergents without having to stop and change the tank during use, a thoughtful design feature that frequent users will surely appreciate.
The difference in detergent tank capacity is an important feature to consider when deciding which electric pressure washer is the best pick. The K1900 model has a more impressive tank capacity that is sufficient for the casual user. More frequent users who want to use more than one type of detergent during use, however, will greatly benefit from the K2000’s dual tank feature.
When it comes to design, all of these models have features that align with the Karcher brand’s trademark convenience and style. All of these models include durable textured wheels, which makes portability a breeze. Similarly, an on/off foot switch makes these devices virtually hands free and incredibly easy to start and stop when in use. An included handle also makes them highly portable, but it is important to note that the K1800, K1900, and K2000 feature a folding handle for easier storage, while the K1700 does not.
Hose storage is another important component when it comes to comparing these power washers. The K1700, K1800, and K1900 models have an included storage bin which holds the hose as well as additional accessories and the device’s power cord. The K2000, however, includes a convenient pressurized hose reel that neatly and easily stores the 25-foot long hose after use. This model still includes a bin for accessory and power cord storage. It’s for this reason that the Karcher K2000 has a superior design that sets it apart from its competitors.
