Karcher 1700 PSI Pressure Washer Reviews: Features and Performance
[toc]
Strong Design
To start with, the Karcher K1700 pressure washer features a sturdy design intended for regular residential cleaning. Like the Karcher 1800 PSI pressure washer, it features an integrated aluminum frame that supports the unit without adding unnecessary weight.
The machine also has metal hose connections, oversized no-flat wheels, and a reliable universal motor. Its three included nozzles are the turbo, 15-degree, and soap nozzles.
Besides, the yellow-and-black finish gives the machine an attractive appearance. Its upright construction makes it relatively easy to store in a garage or shed.
Universal Motor
The Karcher K1700 uses a universal electric motor that delivers reliable performance for light-duty and moderate residential cleaning. Although universal motors can operate on AC or DC in certain applications, this pressure washer is designed for a standard 120V AC electrical supply. You should never connect it to an unsupported power source.
The motor is housed within the machine’s protective structure. The pressure washer also comes with a 35-foot power cord and a 20-foot high-pressure hose, giving users a reasonable working range.

Powerful Unit With Up to 1700 PSI
The Karcher K1700 delivers a maximum rated pressure of 1700 PSI and a maximum flow rate of 1.2 GPM. Multiplying these figures gives 2040 cleaning units, although the maximum pressure and maximum flow may not occur simultaneously during actual operation.
This cleaning capacity is suitable for washing patio furniture, garden equipment, trash cans, vehicles, and moderately dirty outdoor surfaces.
However, stubborn concrete stains and extensive heavy-duty cleaning may require a more powerful machine. If you need additional cleaning power, consider the Karcher K5 Premium 2000 PSI pressure washer.
Remember that pressure alone does not determine cleaning performance. Water flow, nozzle selection, cleaning solution, and the condition of the surface also matter.
Tall Handle
Another feature that makes this unit convenient is its tall, comfortable handle. It allows you to move the pressure washer around your property without constantly bending down.
When moving the unit, keep it upright and avoid pulling it by the hose or power cord. This reduces the chance of damaging connections or accidentally tipping it over.
Large Wheels
Apart from its sturdy handle, this electric pressure washer comes with two oversized, no-flat wheels for easier maneuvering around your driveway, garage, or sidewalk.
You don’t need to lift the machine every time you change your cleaning position. Simply move it using the handle while keeping the hoses and electrical cord clear of the wheels.

Three Quick-Connect Nozzles
One of the best features of the Karcher K1700 is its three interchangeable nozzles:
- Turbo nozzle: Produces a rotating, concentrated spray for stubborn dirt on suitable hard surfaces.
- 15-degree nozzle: Provides a focused spray for cleaning durable surfaces where additional pressure is needed.
- Soap nozzle: Delivers a lower-pressure spray that allows detergent to be applied.
Always choose the nozzle according to the surface. A turbo nozzle can damage vehicle paint, wood, soft stone, and other delicate materials. For vehicle washing, use a compatible wider-angle nozzle when needed, maintain a safe distance, and test a small area first.
Bucket Storage Bin
The Karcher K1700 has a removable storage bin that helps keep your cleaning accessories organized.
This storage area can hold small tools and accessories when the machine is not in use. It is particularly helpful if you frequently move your pressure washer between different cleaning locations.
Removable Detergent Tank
The removable half-gallon detergent tank makes applying cleaning solution more convenient. Instead of carrying a separate container, you can fill the onboard tank with a detergent designed for pressure washers.
Use the soap nozzle when applying detergent, as the detergent system requires low-pressure operation. Follow the cleaning solution’s instructions and rinse the tank after use.
Avoid household bleach, solvents, and chemicals that are not approved for your pressure washer because they may damage internal components.
Easy-to-Use On/Off Footswitch
If you’re new to electric pressure washers, the Karcher K1700 is straightforward to operate. Its large on/off footswitch allows you to start or stop the machine without bending down.
This feature is helpful when you need to pause between cleaning tasks. However, always release the pressure and disconnect the electrical supply before changing accessories or carrying out maintenance.
The K1700 is also easier to transport than many larger gas-powered models from Generac or Briggs & Stratton.
Warranty
Karcher provides a three-year limited warranty for the K1700, covering qualifying defects in materials and workmanship under the warranty terms.
Normal wear, misuse, improper storage, and damage caused by freezing may not be covered. Review the warranty documentation supplied with your particular machine before making a claim.
Troubleshooting the Karcher 1700 PSI Pressure Washer
Although the K1700 is easy to operate, some problems can develop over time. The following troubleshooting table covers common issues and practical solutions.
| Issue | Possible Cause | Solution |
|---|---|---|
| Pressure washer not turning on | Power supply problem, tripped GFCI, or defective switch | Check the outlet and reset the GFCI. Make sure the electrical connection is dry. Contact Karcher support if the problem continues. |
| Fluctuating pressure or pulsating operation | Air inside the system, clogged nozzle, or inadequate water supply | Turn off the machine and purge trapped air by running water through the spray gun. Clean the nozzle and check water flow. |
| Water leakage from the pump or connections | Loose fittings, damaged O-rings, or worn seals | Disconnect the power, release pressure, and inspect connections. Replace damaged seals or contact an authorized service center. |
| No detergent being dispensed | Wrong nozzle, empty tank, or blocked detergent line | Install the soap nozzle, refill the tank, and inspect the detergent system for blockages. |
| Motor runs but water pressure is weak | Clogged inlet filter, kinked hose, blocked nozzle, or insufficient water supply | Clean the inlet filter, straighten the hose, and inspect the nozzle. Seek professional service if pressure remains low. |
| Machine stops during operation | Electrical protection activated, overheating, or power supply issue | Switch off the machine and allow it to cool. Check the electrical supply and follow the manufacturer’s troubleshooting instructions. |
Important: Never inspect or repair pressurized connections while the unit is running. Switch off the machine, unplug it, turn off the water supply, and squeeze the trigger to release trapped pressure before maintenance.

Karcher K1700 vs K1800 Pressure Washer Comparison
The K1700 and K1800 are both designed for residential cleaning. The K1800PS is a closely related 1800 PSI model available in Karcher’s Performance Series. Specifications can differ between older K1800 versions and newer K1800PS configurations.
| Feature | Karcher K1700 | Karcher K1800PS |
|---|---|---|
| Maximum Pressure | 1700 PSI | 1800 PSI |
| Maximum Flow Rate | 1.2 GPM | 1.2 GPM |
| Calculated Cleaning Units | 2040 CU | 2160 CU |
| Motor Type | Universal | Universal |
| Power Source | 120V Electric | 120V Electric |
| Detergent Tank | 0.5 gallon | 40 ounces |
| Accessory Connections | Universal-compatible connections | Universal-compatible connections |
| Weight Without Accessories | 20.7 pounds | 20.7 pounds |
| Dimensions | 17.25 × 16.5 × 33 inches | 17.5 × 16.5 × 33.1 inches |
| Best For | Everyday household cleaning | Household cleaning requiring slightly higher rated pressure |
The K1800PS offers slightly higher rated pressure, but the difference is not dramatic. For most regular home cleaning tasks, the K1700 remains a practical choice. Consider the price, included accessories, and the cleaning jobs you perform most often before deciding.
Bottom Line: Is the Karcher K1700 Worth Buying?
Finding a suitable electric pressure washer for your home is not always easy, but the Karcher K1700 offers a good combination of portability, convenience, and cleaning performance.
Its lightweight construction, sturdy frame, large wheels, and removable detergent tank make everyday cleaning more manageable. The maximum 1700 PSI pressure rating is sufficient for many residential applications, including patio furniture, outdoor equipment, and routine driveway maintenance.
However, it is not the best option for heavy commercial work or extensive concrete cleaning. More powerful machines, such as the Generac 3100 PSI pressure washer or Simpson 3000 PSI pressure washer, may be better suited to tougher projects, depending on their specifications.
Overall, the K1700 is worth considering if you want an easy-to-use electric pressure washer for regular home maintenance. Its three-year limited warranty is another useful advantage.
Frequently Asked Questions
Can the Karcher K1700 use a 50-foot pressure washer hose?
Yes, a compatible longer high-pressure hose may be used, provided its pressure rating, connections, and other specifications meet Karcher’s requirements. The K1700 comes with a 20-foot hose and uses standard M22 connections. A longer hose may cause some pressure loss, so check compatibility before purchasing.
Is it possible to winterize this pressure washer?
Yes. Drain water from the hose and system, then use a manufacturer-approved pump protector according to the instructions. Store the unit somewhere it will not freeze. Water left inside the pump can expand during freezing and cause damage.
How do I stop the garden hose connection from leaking?
First, turn off the machine, unplug it, and release pressure. Then inspect the inlet adapter, washer, and hose connection. Replace damaged washers or fittings and tighten connections correctly. Avoid overtightening or relying on tape to repair damaged seals.
Can I wash my car with the Karcher K1700?
Yes, but select an appropriate nozzle and maintain a safe distance from the paint. Avoid directing the turbo nozzle at painted surfaces, rubber seals, sensors, or damaged trim. Use vehicle-safe detergent and test a small area before cleaning.
Can the Karcher K1700 draw water from a bucket?
The K1700 is designed to receive a suitable pressurized water supply through its garden hose connection. Do not assume that it can self-prime from an unpressurized bucket. Check the manufacturer’s instructions before attempting an alternative water supply.
Is the Karcher K1700 suitable for cleaning concrete?
Yes, it can remove light dirt and grime from concrete. However, heavy stains, large driveways, and deeply embedded dirt may require more cleaning power or additional cleaning solution.
Does the Karcher K1700 require regular maintenance?
Yes. Clean the inlet filter, inspect hoses and connections, rinse the detergent tank, and store the machine properly after use. Regular maintenance helps reduce leaks, poor pressure, and premature component wear.
