Karcher makes a few of the best electric pressure washers ever, hands down.
You cannot shop for an electric pressure washer without considering a few great models of Karcher. And that’s the beauty of them: they have one great model for every purpose and every group of users.
They have so many offerings in the market that it could get a little confusing to decide between their very own models.
This ‘Karcher pressure washer reviews’ guide aimed to draw a clear picture of what exactly Karcher has to offer to the market.
Let us see.
You’ll find a good number of decent brands while looking for a pressure washer, then why Karcher?
Well I guess, Karcher could be called the “Apple” of the cleaning industry, and even better in one aspect, that they listen to their customer.
Karcher probably is the most reliable name when it comes to cleaning equipment, and we can see why –
Karcher has the longest history…
Karcher, the German company, has been around since 1950, and Alfred Karcher, the founder of the company was the inventor or creator of the first water pressure washer ever.
With more than 70 years of experience and being the pioneer of making the equipment, they know every ins and outs of it.
What is more important is since they’re such a big name and sell in huge numbers, they can afford to spend a big chunk of their money for research and development purposes which have made Karcher equipment continue to get better.
To put in numbers, in 2015 Karcher had annual revenue of 2.3 Billion dollars with a B, majority of which came from their pressure washer business that they sold over 60 countries.
The ability to invest a lot in research and development has allowed them to stay multiple steps ahead of the competition in terms of innovation. Now you get it why did I cite them as the “Apple” of the cleaning industry?
One for every purpose
Another convenient aspect of Karcher is that they have something for everyone and every purpose. They offer 21 electric and 18 gas pressure washers (that too excluding professional-grade options) which is way more than 18 that Sun Joe, AR Blue Clean, and GreenWorks offers combined.
From 1.25 GPM and 1500 PSI up to 3.6 GPM and 4000 PSI, they have one for every purpose.
A few other reasons that make me mostly recommend Karcher over other brands –
● Ease and convenience of use of most of their models.
● Long-lasting pumps that reduce maintenance cost.
● Patented nozzle technology.
Karcher Pressure Washer Reviews – Top Models to Consider in Each category
To make your shopping not much overwhelming, here’s our recommendation of the best Kärcher pressure washer under each category. These in-depth Karcher pressure washer reviews are aimed to break down the product in detail and let you judge & decide.
Best in Budget – Karcher K3 Follow-Me Electric Pressure Washer
The K3 serves you with the easiest portability that probably a pressure washer ever would, being the only renowned unit having 4 wheels. On top of that, it weighs only 15 pounds, and you still wonder why it’s named “follow-me”?
This pressure washer is literally designed to follow you as a trusted cleaning buddy.
The power it delivers is sufficient for light to medium-duty jobs. It throws out 1.3 Gallons of water per minute at 1800 PSI, so don’t go by the small footprint of it. It packs enough punch to suit a range of cleaning tasks around the home.
Don’t expect to clean patios or driveways with ease with it. That task will require supporting attachments and some effort. All other cleaning tasks including cleaning your car? This cute boy got you covered.
The power it packs is greatly utilized by the 2 different wands (included). The Vario Power Spray wand lets you easily switch between low to high pressure, and everything in between, while it’ll automatically dispense soap when you keep it in low-pressure mode.
And when you need aggressive cleaning, you deploy the DirtBlaster Spray Wand that’s designed to help you get rid of the most stubborn stains. It’s your perfect weapon to deal with concrete, stone, bricks, and other hard surfaces.
Do not get tempted to use that on delicate surfaces as well, otherwise, you might end up hurting the surface.
● Highly maneuverable.
● Powerful enough for medium-duty jobs.
● Different wand for serving different purposes.
● Got build-quality issues here and there
Best Electric PW for Most People – Karcher K5 Premium
The K5 premium makes it easy for me to recommend one best Karcher electric pressure washer to most people, thanks to the balance of power, price, longevity, ease of use, and effectiveness it offers. It’s one of the top systems that Karcher have ever made,
It’s one of those electric pressure washers (which is still affordable) that allows you the freedom to think of getting any cleaning job done around the house. It simply punches above its weight to get done with heavy-duty jobs with not much extra effort.
The freedom to adjust the pressure doesn’t let you get worried about introducing this bad boy to delicate surfaces.
The real beauty of this rig has to be the simplicity of design and ease of use of it. Someone who’s an amateur at using pressure washers, won’t face the hardest of times with it.
The lance offers you 3 different settings that you can conveniently toggle with just the twist of the handle – easy. The handle itself offers great control over water flow and pressure.
The K5 promises to serve you for a long, and that shows. Take the water-cooled motor for example which does not let the motor get too hot in long sessions and more importantly, can significantly improve the lifespan of it.
● Adjustable all the way to suit different jobs.
● Operation is a piece of cake.
● A powerful rig that gets a range of jobs done.
● Comes with a built-in detergent tank
● Ensures great value for money
● Setting up initially is tricky.
For Car & Home – Karcher K2 Car & Home Kit Electric Power Pressure Washer
As I said, Karcher has a solution for everything. When you need something mostly to clean your car and thus do not want to invest in a all-around great model that could cost double, the K2’s Car & Home kit variant is your best bet.
One might ask, how can you recommend this, a 1600 PSI 1.25 GPM pressure washer as a great car cleaning kit while there are other great models like the K5?
The point is the price to performance ratio it offers and serving the specific needs better. Karcher K5 is one of my most favorite electric pressure washers and it’s amazing for a range of jobs, including washing cars. But how much does it cost?
At the time of writing this piece, double of the K2 Car & Home kit.
That makes the K2 stand out for people shopping for a washer mostly to clean their cars, and also the fact that since it’s a specialized car cleaning kit, it offers a 5 piece car & home kit in the package, unlike any other models.
The power it outputs is more than sufficient to get your car cleaned, but not it the fastest of time that a bit more powerful pressure washer would get done within. Light to medium-duty home cleaning tasks will be carried out easily as well with this rig.
● Great choice within budget for cleaning automobiles.
● Carries out medium-duty home jobs.
● Lightweight and portable.
● 5-piece home and car kit included.
● Could seem a tad underpowered on a few occasions.
Best Gas Pressure Washer from Karcher: Karcher 11073830 G2700R
Gas pressure washers have one key advantage that not even the best electric model could beat, which is the room to deliver a lot of power & pressure. Gas pressure washers are blessed by gas-powered engines that are naturally designed to produce a lot of power.
That proves one clear point, that if you need really heavy-duty jobs done, go gas. Even an entry or medium-level gas pressure washer is capable of producing more power than the best of electric washers, and that is just pre-determined by their power source.
From Karcher, the best offering in gas is the G2700R. It arrives pretty much in a ready-to-go state and makes your life easier.
The heavy unit is carried around by two sturdy 12-inch wheels. The weight is well-justified by the sturdy frame of it.
The 196 cc Karcher KPS engine produces a ton of power, 2700 PSI to be exact, which gets rid of the oldest grime and most stubborn stain. Get this machine for the toughest job around the house and you won’t be disappointed.
A common issue with a gas pressure washer is with start-up hiccups, which is quite uncommon for this unit. It starts well every time thanks to the anti-choke technology of Karcher.
● Anti-choke engine for a consistent start.
● A powerful rig that gets any cleaning job done
● Simple set up.
● Build to last for years to come.
● Large and heavy unit.
● Operating cost is a concern.
Karcher Pressure Washers – Buyers’ Guide
Though the fact that Karcher offers a lot of models is a blessing, it could be a little overwhelming at times, especially when you’re trying to find your perfect companion among those options.
This buyer’s guide is aimed towards introducing you to Karcher’s different product lines and their best-served purpose, so you can judge which model is perfect for your needs.
Karcher’s’ 4 Core Product Models
Karcher’s’ pressure washer lineup mainly consists of 4 models: K2, K3, K5, and K7. Each model has different versions say: eco, car & home, premium, follow-me, etc.
These are variations to the core product having the same pump, pressure, and GPM count, with minor tweaks and different sets of accessories. It helps to meet more specific needs.
In 2016, Karcher pushed its top of the line pressure washers to introduce another version named ‘Full Control’. However, not all models have a ‘Full Control’ version of them yet.
Karcher K2 – The Entry Level
Karcher’s’ entry-level pressure washers go under the K2 product line. They have a 1400 watt motor that produces 1600 PSI pressure and kicks out 1.25 gallons of water per minute.
With such numbers, the K2 is ideal for lightweight tasks including washing down your garden furniture or bike. You could push it to carry out tasks like cleaning your car but that’ll demand extra time and effort from your side.
It has multiple variants including the regular K2, the compact, full-control, premium, and ergo. These variants have minor tweaks within to serve more specific needs better, and also create a range of prices.
Karcher K3 – Lower Midrangers
The lower midrange pressure washers from Karcher fall under the K3 lineup. Featuring an 1800-watt motor, it produces 1900 PSI pressure with a 1.5 GPM water flow. The added power makes it good enough for carrying out more demanding jobs like cleaning your car, driveways, etc.
The K3 does not only pack more power than the K2, rather it’s the starting point of having premium features.
For example, the models onwards from here have water-cooled motors, water suction capabilities, plug, and clean detergent intake mechanism, etc.
However, the K3 lineup is not the most loved middle ranger lineup from Karcher as it’s overshadowed by the K5 series, known as the higher-midrange lineup that packs all the good features of the K3 lineup and punches above its weight to carry out few heavier-duty jobs as well.
Karcher K5 – Higher Midrangers
Karcher K5 is the powerful midrange series of Karcher and offers a few models that are best suited for most people.
Featuring a 2100-watt motor, it is able to spray 1.4 Gallons of water per minute at 2000 PSI, which will be enough for most jobs you need to carry out at your home.
The added features are carried out to these models from the K3 with a few more, like the Full Control Power Gun with LED Display. You can power wash Bikes, Cars & Vans, Larger Patios, Outdoor Furniture, Driveways, Garage Doors, Brickworks, and whatnot.
Most people prefer the K5 series as it can tackle all jobs at home yet does not cost that much as a top of the line K7 model would.
Karcher K7 – The Power to Clean Anything
Talking of top of the line pressure washers, they go under the K7 series. This model is simply designed to carry out whatever home-job you throw at it, with ease. With a whopping 2800-watt motor, it throws out 2.4 GPM with 2400 PSI.
Such power takes them close to a few powerful gas pressure washers as well. Even some small professional jobs are carried out with these series of pressure washers.
You can clean 4×4’s, even Boats with this rig. When you want to have the power to clean anything at home effortlessly and are not much concerned about the budget, this is the best Karcher pressure washer series for you.
Best Karcher Pressure washer for Car Cleaning
When your prime job is to clean your car, you want to have a close look at PSI and GPM count. From a general sense, it might seem that the higher the pressure the better it cleans.
While that is true, the fact that such pressure might damage your car’s body and paintwork also comes into play. When you don’t want to struggle to get rid of stubborn stains and keep your cars’ paintwork intact at the same time, you want to get something around the 2000 PSI mark.
You can already guess which are the models for cleaning your car then, can’t you?
While both the K3 and K5 series will do the job well, I’ll recommend the K5 over the K3 for its added freedom of carrying out other heavy-duty jobs around the house.
Digging out on more powerful models like the K7 since you’ve got other heavier jobs to carry out? No problem, just set the pressure at the 2000 PSI mark from the pressure adjuster that all Karcher washers offer and it works like the K5.
Best Karcher Pressure washer for Patio & Driveway
Getting rid of stubborn moss, dirt, and stains and having a clean and shining driveway or patio is a power-demanding job, no doubt. Your driveway may have not been washed for years and the stains have started to seem permanent.
It’ll require power to go through them and thus, I primarily recommend the K7, if not the K5 series to get the best result cleaning your driveway and patio.
They’re both powerful series of pressure washers. However, they alone might not bring the desired result. To get the best possible result and reduce your effort needed, you’ll need attachments like the surface cleaner.
They’re cheap attachments mostly costing below 20 bucks yet they remove a lot of burden from your pressure washer and you too, which also lengthens the lifespan of your rig.
How Do Karcher Pressure Washers Compare to Other Popular Brands?
Karcher, without any argument, is the biggest electric pressure washer manufacturer. But what makes them stand out? What are the key differences in terms of value proposition compared to its competitors?
- Karcher vs Sun Joe
Sun Joe’s key value proposition is ‘Value for Money’. Their numbers always look great. You’ll get a pressure washer with higher PSI and GPM count for the money than you would get from Karcher’s.
But in the long run, Karcher stays and Sun Joe doesn’t. Karcher’s reliability is unmatchable by current Sun Joe’s product offerings. With an initial bigger investment by buying a Karcher’s, you ensure cheap maintenance so it more than evens out.
It’s like Apple vs Xiaomi. Xiaomi’s numbers and performance at the beginning are quite impressive but after a couple of years, you’ve got to replace them while you can keep using Apples’ devices for double than that without hiccups.
Sun Joe, by any means, isn’t a bad manufacturer. Rather, their value proposition is different.
- Karcher vs Ryobi
Ryobi is a solid brand of pressure washers under the giant company named Techtronic Industries. Their offerings to the market are great but limited.
Ryobi offers only a few good models while Karcher has a range of options for all different purposes.
Ryobi’s failure to offer a range of specific groups doesn’t let them be as a widely accepted brand as Karcher’s to most people.
- Karcher vs AR Blue Clean
AR, AnnoviReverberi is one of those few pressure washer manufacturers that I think goes hand in hand with Karcher’s. It’ll be a difficult job to clearly separate them as both maintain the quality of their products.
While one offers a little advantage on one aspect, the other catch up by offering superiority on another. You can’t go wrong with either of the brands.
- Karcher vs Greenworks
Greenworks is pretty much on the same page with Sun Joe. Their core value proposition is to offer impressive numbers & performance in the short term, while it’ll take money and effort for their maintenance in the long term.
If you keep Karcher above Sun Joe, you’ll keep it so compared to Greenworks as well.
How to Increase the Cleaning Capacity and Performance of Your Karcher?
Pressure Washer alone won’t cut it all the time. When you attach an appropriate attachment to it, you increase its effectiveness for a given job by a big margin and also help to reduce the burden on the washer.
Here are a few great yet cheap attachments that’ll increase the cleaning capacity and performance of your Karcher Pressure Washer:
Rotating Wash Brush
Perfect attachment for cleaning smooth surfaces gently, including car, house siding, and windows. Scrubs and loosens dirt and grime while pressurized water pushes them away.
Helps you reach further distances that you otherwise would have to reach with ladders if we’re talking about vertical distance, like cleaning your second storey windows. That’s a risky job and the extension wand reduces risk.
Power scrubber scrubs powerfully and ideal for getting stubborn stains off from your front stairs and other edges.
Your best buddy for cleaning large flat areas like driveway, deck, etc. Dual spinning nozzles capture more area at once and you need fewer passes to get the job done
Let’s change the degree of the spray by just turning and twisting. Go from blasting your kitchen exhaust hood to cleaning windows without effort and in the blink of an eye.
