ELECTRIC PRESSURE WASHERS

We currently sell four powerful pressure washers with water-cooled motors:

• K5 Premium
• K5
• K4 Premium
• K4

In addition to being water-cooled, these are also induction motors – which are generally more powerful, efficient and longer lasting than universal motors. 

There is no need to buy a special garden hose. A regular, good quality garden hose with these specs is ideal:

• Preferably 5/8" or larger diameter (5/8" is the most common hose diameter in the US)
• 50 Feet or less in length

A hose with these specifications should deliver the necessary water flow. Most homes will already have one or more of these.

You do need to have sufficient a water flow rate from your outdoor spigots – see the next question for more details.

Any regular residential water supply is fine (city or well water). For optimum results, you should have a water flow of 4 gallons per minute at a minimum of 40 PSI. Most homes in the U.S. will meet this requirement.

To find out your home's water flow rate: 

• connect your garden hose to an outside spigot
• insert the other end of the hose into a 5 gallon bucket
• turn the water spigot fully on
• allow the water to run into the bucket for one minute, then switch it off

After you have followed the above steps, see how much water is in the bucket. It should be at least four gallons or more.

(Side note: Our K4 and K5 models can also draw water from a standing source, like a bucket or cistern. Please consult the owner's manual for additional information. Be sure to use a suction hose with filter if you plan to draw water from a standing source.)

All of our electric pressure washers are certified for safety and equipped with a GFCI (ground-fault circuit interrupter). Furthermore, they are double insulated, so they are actually designed to work in a wet environment! The amp draw is a house-friendly 13 amps on most models. Every day millions of customers around the globe rely on our electric power washers to safely and easily clean their homes. 

Yes, but ...

While we do not encourage the use of extension cords, if one is necessary, please make sure it is:

• outdoor rated
• size 14 gauge or larger
• no longer than 50 feet

Our electric pressure washers are designed to be used with or without soap/detergent. We highly recommend our concentrated, environmentally friendly Multipurpose and Vehicle Wash & Wax detergents – these will help reduce your cleaning time and clean more thoroughly.

Corrosive chemicals such as bleach or chlorine can harm the  pump and should never be used. Please note that use of corrosive chemicals will void the warranty.

No

These are residential cleaning machines designed to work with your home’s tap water. The water temperature should not exceed 104℉. Use of hot water (e.g., from a water heater) will damage a residential pressure washer's pump.

For most homes it is not necessary to clean with hot water. Use soap/detergents instead to help loosen dirt and grime, if needed.

If you absolutely need to clean with hot water, please consider our line of commercial hot water pressure washers.

It depends on which model you have –

Kärcher K2, K3, K4 and K5 models ship with the following spray nozzles:

• Vario Power Spray (VPS): This nozzle allows you easily turn the water pressure up and down by simply twisting the wand. Advantage: you never need to worry about which nozzle to use! Tip: turn the wand to the lowest pressure setting to dispense detergent. 
• Dirtblaster®: Use this turbo wand when you encounter hard surfaces that need more intense pressure than the Vario nozzle provides. It concentrates the spray down to a rotating pencil jet for super intense cleaning! Not for use on delicate surfaces (use the Vario nozzle on delicate surfaces).

The VPS and Dirtblaster wands attach directly to the included spray gun.

------------------------------------------------------------

Kärcher K1700, K1700 Cube, K1800, K1900 and K2000 models ship with the following spray tips / nozzles:

• 40° nozzle / tip (white): Always start with this nozzle, it is designed for general purpose cleaning.
• 15° nozzle / tip (yellow): When you need more pressure, attach this nozzle.
• 65° nozzle / tip (black): Use this nozzle to dispense detergent.
• Turbo nozzle: For use on hard surfaces with stubborn soiling and stains, this nozzle produces the most pressure. Not for use on delicate surfaces!

All four spray nozzles / tips attach to the spray wand included with these models.

Please consult the respective operating manuals for additional information and nozzle usage guidelines. 

The gallons per minute (GPM) on these Home & Garden models ranges from 1.2 GPM to 1.5 GPM. Please see each pressure washer's product page for the exact GPM rating. 

Our residential electric pressure washers are designed to be maintenance-free. However we do offer a few tips to keep them in top shape:

• If your model has a removable detergent tank, you should rinse it after you're done cleaning
• If you live in an area where temperatures fall below freezing, you should use a Pump Guard before storing it for the winter
• You may also want to use a Pump Guard during the warmer months to help lubricate and protect the internal pump components

All pressure washers should be stored in an area that is protected from extreme cold or heat. For most people this will be a garage, basement or tool shed. 

While you can purchase all of our models here on our site, you can also buy them from popular retailers as well.

No

We are unable to sell our K6 and K7 models in the US due to their voltage requirements. In Europe the standard voltage is 230v. The K6 and K7 are powerful pressure washers that require 230v in order to generate their 2300+ PSI.

In the USA, the standard voltage is 120v. Therefore we are able to offer our K2 - K5 models, up to 2000 PSI, but not our K6 and K7 models.

(By the way, any company that claims their home electric pressure washers in the US are generating significantly more than 2000 PSI is ignoring PSI measurement standards. It's simply not possible given our 120v power supply.)
