Karcher K5.540 Review

Karcher K5.540

There are quite a few cleanup jobs around the home and garden that can be a lot of work to do by hand, whether it is washing your car, cleaning off your deck or patio, or getting seasonal grit and dirt off of windows and window screens. Any one of these jobs can take a lot of time and effort to get done right if you are just using a low pressure garden hose or worse, a bucket and a sponge.

An electric residential pressure washer is a great tool for helping you finish these kinds of chores quickly and with minimal effort on your part. These handy machines can tackle the vast majority of cleaning jobs you have to do in your house and yard. With high powered sprays of water, an electric pressure washer can blast dirt and grime away from surfaces in seconds, leaving them looking great.

Review Summary

It comes with multiple wands for tackling different kinds of jobs, an onboard detergent reservoir, and a Quick Connect System for all hose attachments, to name a few.

Description

review descriptionWhen you open the box of the Karcher K5.540, you are instantly struck by what a good looking pressure washer it is. It has a unique aesthetic and great design notes, as well as a lot of handy accessories that are going to be very useful when you start using it. You will also be surprised by how compact and lightweight it is: this little guy weighs just 31 pounds and has dimensions of just 15.5 x 16.5 x 23 inches. Its size will make it easy to find storage space for it just about anywhere in your garage or home. And the fact that it is so lightweight and has big wheels will make it easy to wheel around your yard while you use it.

Do not be fooled by its appearance, though. The Karcher K5.540 packs a lot of power under the hood, and it is evident by the fact that it produces a spray that tops out at 2000 pounds per square inch with a flow rate of 1.4 gallons per minute. That results in a pretty high power rating for a residential electric pressure washer. Power rating is the product of PSI and GPM, and it rates the overall cleaning ability of a pressure washer. With a power rating of 2800, you can count on the Karcher K5.540 to tackle just about anything you can find around your house or yard that needs cleaning.

The Karcher K5.540 has a lot of great accessories and extra features. It comes with different wands for taking care of different jobs, and onboard detergent reservoir, and a convenient reel for winding up the hose when you are done cleaning. These features were added after Karcher got feedback from its customers – which means this model is practically designed by the people who use it most.

Pros

review prosBy taking customer feedback into account when they were designing this model, Karcher made sure it has all of the great features you need on a residential electric pressure washer. As a result, the Karcher K5.540 has some of the best design notes you can find in its class. Because of this, it is going to be very easy and convenient to use this model around the home and yard. Let’s take a look at its best features.

  1. High pressure and flow rate : The reason a high pressure and flow rate is important on an electric pressure washer is because it gives you options. You probably will not have to use the highest setting of 2000 PSI often, but having it means you will have a wide range of pressures to choose from so you can always choose the best one for every job. The buzzwords here are convenience and freedom of choice, and with the Karcher K5.540 you get a lot of both.
  2. Tons of great accessories : There are accessories everywhere you look on this pressure washer. It comes equipped with a quick-connecting trigger gun and child safety lock, as well as two extra spray wands for different jobs. It has a pressurized hose reel for winding up the hose and storing it onboard. All hose connections have Quick Connections for faster startup times and a centralized Easy Track hose feed system for easier use. Every part of the Karcher K5.540 is designed with convenience in mind.
  3. Compact and lightweight : Even though it is a powerful pressure washer with tons of accessories, the Karcher K5.540 is still fairly compact and lightweight. That means you will not have any trouble finding enough storage space for it in your garage or basement, as it easily fits on any shelf or in any corner. Because it only weighs 31 pounds and has large wheels, just about anyone will have an easy time maneuvering it around their yard or anywhere else they need to take it.
  4. Onboard detergent reservoir : This is one of my favorite features. The Karcher K5.540 has an onboard, removable detergent tank. That means you can combine chemical solvents and soaps with the spray for washing out tough stains easily: just attach the tank, fill it with soap, and you are all set. As if that wasn’t enough, the pressure washer also has an adjustable detergent flow dial so you can control the amount of detergent used.
  5. Excellent price : And with all of these great features, the Karcher K5.540 still has a pretty decent price, especially when you compare it to many similar electric pressure washers. That means you can get all of the convenience, performance and cleaning power this pressure washer provides without having to break the bank to get it. And in the long run, it is important to make sure you are getting what you need without spending a fortune on it.

The Karcher K5.540 2000 PSI, 1.5 GPM electric pressure washer is a high performance machine that offers plenty of cleaning power and lots of convenience. It produces no emissions, runs quietly, and is compact and easy to use. This is a great machine for residential use: it has lots of versatility for tackling a lot of different cleaning jobs quickly and efficiently.

Cons

review consAs surprising as it may seem, in spite of the fact that it has so many great features, there are a few areas in which the Karcher K5.540 is not quite perfect. At the same time, some of these drawbacks are par for the course with a small electric pressure washer, but others could also be better. Let’s take a close look at them.

  1. Upright design is top-heavy : This is the one design area in which the Karcher K5.540 tends to fall down on the job – literally. Because of its upright and fairly top-heavy design, the pressure washer is prone to tipping over a lot while you are using it, particularly if you tug on the hose too quickly. What the machine really needs is some sort of support stand to prevent this. You can try to lay it down while using it, but this is inconvenient.
  2. Quick connects may have slow drips : This is a chronic problem on small residential pressure washers – the hose connectors have plastic O-rings instead of brass fittings, and as a result they tend to develop leaks. Fortunately on the Karcher K5.540 it’s just a slow leak that does not affect the pressure or flow rate noticeably, but it is still a pain. While you can always fashion your own connector with brass fittings, this isn’t something that should be the consumer’s job.
  3. Plastic construction is not very durable : The body and a number of key parts on the Karcher K5.540 are made of plastic. While this is great for helping keep its weight down so it is not too bulky, it also leaves it vulnerable to damage – and this problem is made worse by the fact that it has a tendency to tip over. If it’s on rocky ground or hard concrete when it tips over, there is a danger of the plastic parts breaking from the force of the impact.
  4. Only sprays cold water : While this is fairly common for residential electric pressure washers, it is still worth mentioning – there is no hot water option for this sprayer unless it’s hooked up to a hot water source. And who has the kind of huge hot water heater that would require? Fortunately, the onboard detergent reservoir means you will still be able to tackle tough stains without having to resort to needing a hot water spray.
  5. High pressure hose is stiff : Due to the fact that it is made of PVC plastic, the high pressure hose is pretty stiff. As a result, winding it up on the onboard reel can sometimes be a bit of a hassle, and once it is wound up, it tends to adopt that configuration, which means that when you unwind it, it will tend to loop back on itself and get tangled up.

I still think that all of the great features described in the Pros section overshadow any of the problems presented by these Cons, and in some cases the Cons are just natural parts of owing a residential electric pressure washer. The machine is limited by its design intent, which is to handle small scale jobs around your house. That said, it would be vastly improved if it was not so top-heavy and had the proper brass fittings on the quick connectors.

As you can see, the Sun Joe SPX3000 has a PSI that is very similar to that of the Karcher K5.540, but because it has a higher flow rate (in GPM), its power rating is much higher. With a low PSI, the AR Blue Clean winds up with the lowest power rating as well. The Karcher K5.540 has the most accessories and is the only one with a water-cooled induction motor. In most other areas, the three machines are quite similar.
