Just watched it. Looks like it was some challenging weather.

Pressure and volume are reduced as pipe/tube length increases.I finally hooked up enough hoses to reach my Grandfalls pressure washer. I used an extension cord for power as I havent installed the outlet yet to that side of the shop...will get to that one of these days.
I ran the water for what seemed like 10 minutes until it stopped spitting and blowing air...figured it was pretty well purged. I started up the Grandfalls and it was louder than I expected. Granted it's a 2200psi and my previous plug-in PW's were 1600ish psi. Just as a test I started cleaning up my utility trailer and I'm not gonna lie, it sucked. I started to think I got totally suckered by the ads and youtube videos...or maybe I just got a lemon. The motor sounded like it was working hard, but the actual water coming out the wand was so low that when i put my hand in the spray, it was pretty pathetic. After about 10 minutes the spray was looking better and the dirty film on the trailer fenders was actually coming off. It kept getting stronger and stronger until it was full on blasting and no way I was going to put a hand in that spray.
I pulled out the entire 100' of pressure hose and it made it all the way around the jeep in the driveway...washed the undercarriage and fenders, never dropped pressure the whole time I was running it after the initial low pressure. The retraction on the hose was a little slow and kind of stopped about 10' short, but a quick pull of maybe 10' off the reel and it retracted all 20' back onto the reel. It has a hose management arm that moves back anf forth to keep it organized as its winding but looks kinda flimsy. I suspect that may be the first thing to have an issue in the future.
So, took a bit to get it up to pressure, but seemed to work well once it did.
Hi,
Having worked for Karcher in my past, one of the common faults is with the length of water feed hose going to the machine.
There is a maximum length of water-feed hose for each machine which the retailer should be able to advise you.
Many people will try to take their machine 80 - 100 metres away from the water source ( tap) and this will generally cause the motor in the water-blaster to go "hunting" for the supply. It will surge and pulsate. A better option is to invest in an extra add-on high pressure hose to lengthen the output side. But of course that is additional cost which is why people would rather add more garden hose to the input side but this is not the best practice.
This way you don't need to lift the blaster on to your roof if house cleaning or take the blaster unit right to the full distance down your drive but rather take the hose & gun to the furtherest point and the motor will perform correctly.
Has anyone tried one of these undercarriage attachments? I still pay for a car wash occasionally just to wash grime and salt off the underside so one of these would pay for itself in a couple cleanings.
I got one of these Greeworks pressure washers the other day. I only used it once to clean the bikes and it worked well. I like that it only weighs 30 pounds and easily moved around the garage. I wish it did not have a cord on it at all, and I could just plug an extension cord straight in. The pressure hose could use a quick disconnect too. Having to carefully wrap the hose/cord up makes it a bit cumbersome. Beyond that, it makes enough pressure to easily clean the bikes. It still has more than enough pressure to blow some water past a seal and into a bearing, so use caution. I think I might take the frame off of it and make it hang on the wall of the garage, it is so light that having wheels is not necessary.
Position the washer in such a way that the outlet is higher then the inlet. A slight tilt should do. Also run the supply hose to the washer before hooking it up so there is no air in there. Hope this helps..Quoting myself to update the Greenworks pressure washer. It has an odd behavior, almost like it has air trapped in the pump. It takes 5min of use to clear out. When the air is trapped, the high pressure line will vibrate and jump around. The pressure output will also be low, maybe at about 50%.
