Karcher Pressure Washers – Find The Best Karcher Pressure Washer For the Job!
Karcher pressure washers are available to perform tasks ranging from simple, occasional cleaning jobs to regular use cleaning large, heavily soiled surfaces. Most units in their residential line of products operate from a 120V, 60 Hz power source. Portable battery powered models as well as gasoline engine powered models are also available. All units in the residential line require a source of cold water.
Karcher first gained global prominence with the invention of the first European hot-water pressure washer back in 1950. With over 50 models in their product line, the company now produces models to fit any budget. Their popular line of cold-water pressure washers have found wide acceptance for residential outdoor cleaning applications.
Their Residential series of Karcher pressure washers are broken down into 5 classes of equipment. Each class is designed to accommodate a different level of difficulty of cleaning task. The 5 pressure washer classes are:
- Entry
- Medium
- Premium
- Hybrid Pressure Washer
- Combustion Engine Class
The following information will be useful in determining which Karcher Pressure washer will best meet your cleaning needs.
Residential:
If you occasionally need to clean small surface areas that are lightly soiled, then an Entry class of pressure washer is ideally suited for you. This would include the K2.0 and K3.0 series of pressure washers. With operating pressures of up to 1800 PSI and flow-rates of up to 1.8 GPM, these units are well suited for relatively light duty jobs. The K2.0 series is perfect for cleaning bicycles, cars, or small patios. The K3.0 series operate at higher working pressures and flow rates, and are therefore better suited for cleaning larger, moderately soiled surfaces.
On the other hand, if most of your tasks consist of frequent cleaning of relatively small surfaces that are lightly to heavily soiled, then a Medium class washer in the K4.0 or K5.0 series family would be adequate. These units have operating pressures of up to 2000 PSI and flow-rates of up to 2.0 GPM. The K5.0 series machines have slightly higher operating pressures and flow rates, and are better suited to cleaning larger and more heavily soiled areas.
For those tasks that require frequent cleaning of large heavily soiled surfaces a Premium class cleaner in the K6.0 or K7.0 series will perform well. These units produce water flow rates of up to 2.6 GPM at operating pressure of up to 2400 PSI. K6.0 washers are exceptional for cleaning heavily soiled areas on a regular basis, whereas K7.0 cleaners may be used more intensively for cleaning large areas.
For your small cleaning jobs, where lack of available 120V, 60 Hz power is a problem, the KHC10 Hybrid Pressure Washer may be right for you. This light weight, hand-held unit runs off of a lithium-ion battery and weighs in at less than 15 lbs. Since it is battery operated, the operating pressure and output flow-rate is significantly less than for the other models. This limits use of the KHC10 to only small, lightly soiled cleaning applications.
If you need to clean large heavily soiled equipment or surfaces on a regular basis, but you don’t have access to electrical power, then the Combustion Engine models are perfect for you. These high-pressure pumping systems are powered by Honda gasoline engines, and operate at up to 2400 PSI. Water flow-rates are up to 2.0 GPM. Mounted on a rugged metal frame with large rubber tires, these systems are easily transported to a pond, stream or any other cold-water source.
As you can see, Karcher pressure washers are available for all of your outside cleaning jobs. Simply select a model that provides the necessary operating pressure and flow rate for your job. With the right cleaning power you can clean your bicycle, auto, patio, brick exterior of your home or even large heavily soiled driveways.
Karcher Electric Pressure Washers
When selecting a Karcher electric pressure washer it is essential that you compare various models on the basis of their relative cleaning capability. Since Karcher Residential class machines only operate with cold water, how well these pressure washers will do your job is a function of only 2 things:
- Nozzle operating pressure.
- Water flow-rate.
Residential Karcher electric pressure washer models fall into 1 of 3 classes. The K2.0 and K3.0 series models fall in the Entry class, The K4.0 and K5.0 series models fall in the Medium class and the K6.0 and K7.0 series models fall in the Premium class. Each model series (K2.0 thru K7.0) has a unique combination of Operating Pressure and Flow Rate. This uniqueness provides valuable insight into the Cleaning Power of that model.
The following data summarizes the Karcher electric pressure washer performance specifications for each model series. The maximum operating pressures and flow rates are shown for each model series.
- K2.0… Operating Pressure of 1400—1600 PSI and 1.5—1.8 GPM Flow Rate
- K3.0… Operating Pressure of 1800 PSI and 1.8 GPM Flow Rate
- K4.0… Operating Pressure of 1900 PSI and 1.9 GPM Flow Rate
- K5.0… Operating Pressure of 2000 PSI and 2.0 GPM Flow Rate
- K6.0… Operating Pressure of 2200 PSI and 2.0 GPM Flow Rate
- K7.0… Operating Pressure of 2400 PSI and 2.6 GPM Flow Rate
Now… what is the relationship between Operating Pressure, Flow Rate and Cleaning Power? To answer that question, let’s take a look at the manufacturers’ suggested usage for each model series. Since this manufacturer has been in the high-pressure washer and cleaning business for over 60 years, who is more qualified to provide us with an informed opinion?
Entry Class (K2.0 and K3.0 Models):
First, let’s look at the Entry class of Karcher electric pressure washers. According to information obtained on the manufacturers’ website, these models are generally best suited for occasional use doing smaller jobs around the house. Furthermore, they add that it is best to use these models where there is only light soiling and the surface area to be cleaned is relatively small. They then go on to say that of the 2 models, the K3.0 models are more appropriate for regular use where cleaning moderate to heavily soiled surfaces is a requirement. An examination of the data above shows that the only real difference between the K2.0 and K3.0 models is the difference in operating pressure. K2.0 models operate at 1400 to 1600 PSI, whereas the K3.0 models operate at 1800 PSI.
Medium Class (K4.0 and K5.0 Models):
Next, let’s consider the Medium class of high-pressure washers. Returning to the manufacturers’ website we find that the K4.0 models are intended for regular use on moderate to heavily soiled surfaces. The K5.0 models have the same cleaning power as the K4.0 models, but can clean large areas with ease. An examination of the data reveals that the difference between the K4.0 and K5.0 models is a combination of higher operating pressure (2000 PSI) and increased flow rate (2.0 GPM).
Premium Class (K6.0 and K7.0 Models):
These models are the top of the line in Karcher electric pressure washers. Both the K6.0 and K7.0 models excel where frequent use cleaning large, extremely dirty areas is a requirement. K7.0 models have the same cleaning power as the K6.0 models, however they are recommended where intensive use is a requirement. Here again, examination of the data indicates that the difference between the 2 models is a combination of higher operating pressure (2400 PSI) and increased flow rate (2.6 GPM).
Conclusions:
So! What can we conclude from all of this? Here is our assessment:
A. If you need to occasionally clean small areas that are lightly soiled you need a machine with the following specifications:
- Operating Pressure in the 1400 to 1600 PSI range
- Water Flow Rate in the 1.5 to 1.8 GPM range
B. If you need to regularly clean small areas that are moderately soiled you need a machine with the following specifications:
- Operating Pressure in the 1800 PSI range
- Water Flow Rate in the 1.8 GPM range
C. If you need to regularly clean small areas that are moderately to heavily soiled you need a machine with the following specifications:
- Operating Pressure in the 1900 PSI range
- Water Flow Rate in the 1.9 GPM range
D. If you need to regularly clean large areas that are heavily soiled you need a machine with the following specifications:
- Operating Pressure in the 2000 PSI range
- Water Flow Rate in the 2.0 GPM range
E. If you need to frequently clean large extremely dirty areas you need a machine with the following specifications:
- Operating Pressure in the 2200 PSI range
- Water Flow Rate in the 2.4 GPM range
F. If you need a machine for intensive use cleaning large extremely dirty areas you need a machine with the following specifications:
- Operating Pressure in the 2400 PSI range
- Water Flow Rate in the 2.6 GPM range
As you can see, selecting the right Karcher electric pressure washer is a matter of first identifying your job cleaning requirements; then matching your job requirements with machines having the appropriate operating pressure and water flow-rates.
