i have the 2nd greenworks pressure washer shown (1700psi) and all you need is the adaptor like the bottom picture shown below. it should also work with any other pressure washer with a quick disconnect like all the pressure washers shown on the end of the wand...

Just get the warranty if I were to use it everyday I would say no,I've been down that road not with the ryobi but with the greenworks.

I have the ryobi 1700 in the picture. I have used it 2 years zero issues no adapters required for a foam cannon. It uses standard quick disconnect fittings
Haven't used the one from HF Ryobi now has a super small one that I wish I had instead its 1600psi and super small

Still thinking of just getting the Harbor Freight one as it's cheap

Super MemberRe: Harbor Freight pressure washer, any good?
The HF will need additional fittings for most tips and it has a shorter hose. It's only about $20 that the small ryobi. I looked at the HF for a long time before going with ryobi
For the record I love HF and I have a ton of tools from there. Not biased against them.11-02-2015, 11:30 AM#9

Vibration Hazard:
This tool vibrates during use. Repeated or
long-term exposure to vibration may cause
temporary or permanent physical injury,
particularly to the hands, arms and shoulders.
To reduce the risk of vibration-related injury:
1. Anyone using vibrating tools regularly or for an
extended period should first be examined by a
doctor and then have regular medical checkups
to ensure medical problems are not being
caused or worsened from use. Pregnant women
or people who have impaired blood circulation
to the hand, past hand injuries, nervous system
disorders, diabetes, or Raynaud’s Disease should
not use this tool. If you feel any medical or
physical symptoms related to vibration (such as
tingling, numbness, and white or blue fingers),
seek medical advice as soon as possible.
2. Do not smoke during use. Nicotine reduces
the blood supply to the hands and fingers,
increasing the risk of vibration-related injury.
3. Wear suitable gloves to reduce the
vibration effects on the user.
4. Use tools with the lowest vibration when there
is a choice between different processes.
5. Include vibration-free periods each day of work.
6. Grip tool as lightly as possible (while still keeping
safe control of it). Let the tool do the work.
7. To reduce vibration, maintain the tool as
explained in this manual. If any abnormal
vibration occurs, stop use immediately

Pressure Washer Operation
WARNING
Do not direct spray from the pressure washer at a person or an
animal. The water stream could cause serious injury.
Caution
Use the pressure washer only on surfaces able to withstand the force of the spray.
1. Replace the non-vented brass oil plug with
the aluminum Pump Breather Plug before
first use. The Pump Breather Plug must be
used whenever the pressure washer is used.
The brass oil plug (without the breather hole)
should be used for transporting only.
2. Choose the Nozzle that best meets the needs
of the job. Only use the Nozzles on surfaces
capable of withstanding the force of the spray.
Only use the Black Nozzle when using pressure
washer detergent. The power of the other
Nozzles will propel mist back at the operator
and can embed detergent into the surface.
3. Pull back the quick connect collar and push the
Nozzle onto the end of the Wand. Make sure the
quick connect collar locks the Nozzle in place.
4. Turn the water supply on and hold down the
Trigger to start the stream. Be aware that
when it is first started, the gun will kick.
5. It is best to start at a low pressure setting, and adjust
the pressure upwards. Test spray the edge of the
surface to be cleaned first to make sure that the
stream is not too strong for the surface. If the stream
damages the surface, turn the Pressure Regulator
Knob counterclockwise to reduce the pressure.
Moving further away from the surface being cleaned
will also reduce the pressure being applied to the
surface. If the stream is still too strong, turn the
engine off, turn the water supply off, discharge the
excess pressure from the gun by squeezing the
Trigger, and change to a lower pressure Nozzle.
6. To increase the pressure, turn the
Pressure Regulator Knob clockwise.
7. Hold the Wand at about a 45° angle when cleaning;
spraying the surface directly could embed dirt into the
surface (especially with the high pressure Nozzles).
Spray at a distance of about three to five feet.
8. Clean vertical and sloped surfaces from the top down.
9. When cleaning horizontal surfaces, occasionally
use the stream to clear the area of excess water.
10. CAUTION Do not allow the Pressure Washer to idle
without the Trigger held down, for more than two
minutes. The water will heat up and damage the
Pressure Washer. RISK OF BURNS! The pump will
also expel very hot water if allowed to idle too long.
11. Hold the Trigger down and move the Wand back
and forth slowly and steadily to pressure wash the
surface. Take special care when spraying surfaces
made of two different materials (brick and mortar,
for example), so as to not damage the softer of
the two materials during pressure washing.
12. If the surface is streaked or uneven at the end
of a job, switch to a Nozzle that has a wider
spray pattern to blend the affected area.
13. When finished; release the Trigger on the
spray handle, turn the engine power switch
to “OFF”, turn the water supply off and
then shut off gas supply to the engine.
14. Squeeze the Trigger to release excess pressure.
15. If Pressure Washer detergent has been
used for the job, run clean water through the
system to eliminate detergent residue.
16. To prevent accidents, turn off the engine and after
the engine has cooled, disconnect its spark plug
wire after use. Drain all water out of the unit.
Clean external parts with clean cloth, then
store the equipment out of children’s reach.

One of the most popular Harbor Freight pressure washer attachments you can buy is none other than this replacement wand. Spray gun wands are very important to pressure washers because they determine the strength and angle of the pressure washer.

What makes this product so special, anyway?
Well, it is one of the most versatile replacement wands in a sense that it is compatible with almost all brands of pressure washers. Obviously, it can fit well with Harbor Freight products. But aside from that, it can also fit well on other brands like Ryobi, Rural King, Power Stroke, and many more. It also works with a high range of pressure ratings. It can work for pressure washers with a max of 4000 PSI, which is very impressive for a replacement wand.

Aside from that, it can fit a number of Harbor Freight models. Therefore, if you happen to have a Harbor Freight Hydrostar model, then this pressure washer pump will fit in very well.
