Nope, tried and to clean off some second story mildew and did not have enough reach/pressure from the ground. Knowing that the wands were difficult to control and the likelihood of my havig toget on a ladder for part of the job anyway, I tried a two nozzle extended reach tip set that my lcal Home Depot also had. Works on your regular wand and extends the distance you can work to about 15-18 feet from the tip. Much cheaper than the long extended wand, met my needs on the mildew and was easier to control from a ladder. Applicaton Note: the extended reach tips may not work on heavier cleaning than mold or mildew and remember that 25 feet of height will be longer when working from the ground.
Safety Note: Working from a ladder or the roof is NOT recommended for the average home owner with a pressure washer, is a higher risk safety hazard than you may normally take and can EASILY result in loss of balance and a potentially deadly fall. If undertaken make sure you and your ladder are firmly planted and properly tied off/secured.

Answer: 
For 25' I would suggest some wand extensions (available on line or at Home Depot) to extend your reach. The closer the tip to your work surface the more power you have. Also depends on how stubborn the dirt/mold on the siding is.

Pressure washers can be difficult to handle with their high velocity spray. They are down right dangerous when you try to operate them while standing on a ladder.

Hi Bob,
Pressure washers can be difficult to handle with their high velocity spray. They are down right dangerous when you try to operate them while standing on a ladder.
Here are a couple of necessary accessories to get your house clean without putting you in harms way.
For effective cleaning with a pressure washer, the spray nozzle will need to be consistently between 12" and 36" from the surface to be cleaned. As you work higher on the wall, a telescoping wand will help you to maintain this consistent proximity to the surface.
Telescoping wand: http://www.homedepot.com/p/Power-Care-18-ft-3-800-psi-Telescoping-Spray-Wand-for-Pressure-Washers-AP31026/202073583#.UjNcs9JJPuQ
Also consider the tip angle to the wall. A pivoting tip coupler helps to keep the proper head-on angle from the tip that cleans best, especially when working at tall angles.

These accessories make cleaning your tall walls a snap!
Thanks for asking.

can you extend the power washer line without losing a lot of power

This question is from 3,000-PSI One Wash Variable Speed Gas Pressure Washer-DISCONTINUED

I want to leave the main unit on the ground and use power washer wand on the roof of a second story house to clean the metal roof- it comes with 30 feet of hose and I want to extend it to 100 feet. I am concerned with the pressure after extending the hose three times the length. it is also desirable to have a longer hose to not have to move the unit so much. I believe I can buy additional hose to extend the power washer line?

Answer: 
I have extended the hose twice the length with no issues. Keep in mind that pressure is a result of resistance to flow, so if the flow decreases slightly based on he distance, step up to a tighter spray on the tip to balance out the difference if needed.

Answer: 
Currently Generac does not offer an extension to the high pressure hose provided with the power washer; the OneWash is designed to be used with a high pressure hose 30 feet in length. If a longer high pressure hose is necessary, the hose should have a diameter of 3/8” to ensure proper water flow as damage done to the unit from using an improperly sized hose will void the factory warranty.

Currently Generac does not offer an extension to the high pressure hose provided with the power washer; the OneWash is designed to be used with a high pressure hose 30 feet in length. If a longer high pressure hose is necessary, the hose should have a diameter of 3/8” to ensure proper water flow as damage done to the unit from using an improperly sized hose will void the factory warranty. The hoses that come with the units are ¼” diameter, but when lengthening the hose you will have a need for more pressure, so if you increase the hose size, you increase the amount of water flowing through, allowing a longer hose to be usable for this unit. Please note that any damage to the power washer due to using a third-party accessory or hose is not covered under the factory warranty. Read Less

Answer: 
I have never extended the high pressure line but I believe you can without loss of power. The unit comes with a 35' line but an optional 50' line is available. Provided there are no leaks, and the line is properly primed, I see no reason for a loss of power.

Rated 4.7 out of 5 by 315 reviewers.
Rated 5.0 out of 5.0 by Best Bang For Your Buck Amazing machine. I have been looking for a gas pressure washer for quite some time now. The fit and finish is second to non. Pressure is amazing and I like that you can select different pressures for different situations. The rubber handle feels great and the trigger isn't hard to hold down unlike other models I have owned. I found the hose and gun storage worked perfect. I wish I could include a picture to show how I store everything. Definitely recommend this machine. You will not be disappointed. July 12, 2016
Rated 3.0 out of 5.0 by Evaluate Construction Overall good specs on paper. However look at how it is built. Here are the downsides: 1. Handle is made out of plastic. Don't try to lift this unit using the handle or you will likely break it. 2. Handle has fold down pivot joints. In theory this sounds great! But in practice this is the weakest part of the handle assembly, they should not have put in this useless feature. It saves very little space, and reduces the integrity of the unit as you can no longer lift it up via handle without feature of breaking the plastic hinge joint. May 4, 2016
Rated 5.0 out of 5.0 by Great machine The engine starts easily and is quiet. The washer performs very well. The only thing I don't like is the hose storage and would really wish the hose was not as stiff. May 6, 2016
Rated 5.0 out of 5.0 by Great Price for a great product I couldn't be happier with my purchase of the Generac Power OneWash. I have been waiting for spring to arrive to be able to get it out and use is again for the season. I am a disabled veteran, and have difficulty walking and use a cane. This washer has been easy for both my wife and I to use. April 7, 2016
Rated 5.0 out of 5.0 by Works Great ! Works really well easy to set up you'll be happy you got it. Thanks Generac April 7, 2016
Rated 4.0 out of 5.0 by Nice and powerful Nicely built pressure washer with lots of power to get the job done. April 6, 2016
Rated 5.0 out of 5.0 by Second Generac power washer, will buy more if needed! My original Generac power washer was near ten years old and had heavy use over the years. When parts were needed in the pump to keep it going, because of its age, some of the small parts were obsolete! Went out and bought a new Generac, that was capable of higher pressure settings, and paid a bit less then I did for the one I bought ten years ago...! I did not want to trash my old washer because the engine ran so great, therefore I found a new pump that fit, ordered it, and now I have two great power washers, and am very happy with both. Larry December 16, 2015
Rated 5.0 out of 5.0 by I bought 2! Great product everything folds up and come apart for great storage. More then enough power for any pressure wash job. I wish it would have came with a 15degree tip. 20 works ok 15 is better from my experience. It's great for any small business I use this pressure washer a lot. It has lasted through the first year! Which is better then some with how much I use this item it really holds up well. The price can't be beat for the quality. Why spend 2000 when you could buy 5 of these. So I bought 2 I'm confident 2 of these will last just as long as one of the industrial models. December 2, 2015
