Karcher K5 Premium Electric Pressure Washer Review

There are millions of reasons why any homeowner should own a pressure washer. The most prominent of which is that it makes outdoor cleaning a breeze. For cleaning decks, walkways, and vehicles, an electric pressure washer is the most reliable tool to use since it uses hardly any water while still delivering an impressive amount of cleaning power.

PSI and GPM Ratings

Two areas where a pressure washer outclasses a traditional garden hose is the amount of cleaning power it delivers while hardly using any water at all. The Karcher K5 uses only 1.4 GPM while producing up to 2,000 PSI. Spraying gutters, driveways, and outdoor furniture clean is much easier and quicker with the K5 compared to the average garden hose which provides only up to 60 PSI while wasting 24 GPM of water.

Noise Levels

Admittedly, pressure washers have one major drawback, which is how loud they can be. However, the K5 breaks the norm with its whisper-quiet motor and purrs while pressurizing water and remains completely quiet when not activated. The only noise you and your neighbors will ever hear will be from the blasts of pressurized water as it hits the surface of whatever surface you’re spray-cleaning.

Variable Wand

Not every surface will require anywhere near 2,000 PSI to clean – e.g. vehicles, windows, metal gutters – which is why it’s important that you adjust the amount of pressure shot out of the spray gun. The K5 Premium comes with a Vario Power Spray Wand which lets you change pressure and spray-fan settings with a twist of the nozzle. You can adjust how much pressure to shoot out of the gun on the fly – an advantage that this system has over traditional quick-connect nozzle tips.

Onboard Detergent Tank

The K5 Premium comes with an onboard detergent tank. To shoot soap out of the gun, fill the tank up with your choice of detergent and simply twist the nozzle to the soap setting. We found that this tool shoots out a satisfyingly thick layer of suds for ultimate dirt-eliminating power.

Onboard Hose Reel

One feature that we think doesn’t get enough appreciation is a built-in hose reel. There aren’t very many things that are more annoying than trying to wrap up a long hose without it tangling or weighing you down. The K5 Premium comes with a reel hose which reels the hose in effortlessly and without tangles and knots. This is definitely a handy feature.

This 32-pound pressure washer can easily move to all corners of your yard for thorough cleaning. It comes with two heavy-duty 7.7-inch plastic tires that travel easily on paved walkways and decks. Some users have complained about the tires’ inability to cross grassy terrain without picking up patches of grass, but you can bypass this problem by lifting the K5 Premium by its suitcase-style handle.

Range of Movement

Another thing that improves the maneuverability of the Karcher K5 Premium is its super-long power cord (35 feet) and pressure hose (25 feet). Despite being a corded-electric model, you have an extremely wide radius to transport and clean. You can further extend your range of movement by using an outdoor-safe extension cord with the appropriate wire gauge.

We’re glad to say that the inner components of the K5 Premium (motor and pump) are highly durable and able to withstand gushing water with virtually no risk of leaking or water damage. Unfortunately, it’s the plastic hose connector that’s prone to damage. Earlier, we commended this model for having large wheels that help it cross all sorts of terrains, but they hardly do anything to keep the unit from toppling over.

In the event that it does, if the plastic hose connector kisses cement, it’ll more than likely snap or break in some way. The good news is that replacements are inexpensive. The bad news is that you can only get them from official Karcher products suppliers.
