Pro's: I've used this pressure washer to clean my home's vinyl clad steel siding. It did a good job, did not damage the vinyl, and it removed all the dirt, spider webs, leaves, pine needles, etc. without a problem. I've used it on my 5th wheel camper--it cleaned the bugs & dirt off quite nicely. I've used it on a 29-year-old wooden green-treated deck and it cleaned the dirt and detritus mildew out of the wood grains, which removed all the black mold or lichens living on the dirt. Please reference the pictures I've uploaded showing the deck boards being cleaned, and showing adjacent areas not yet cleaned. I've used it to remove the grass growing between the bricks in a walkway--it blasts the grass & weeds right out. Of course, it also removes the sand from between the pavers, but I anticipated that, and had a bucket of sand ready to sweep back into the cracks. I've tested all five spray heads--they work as described by the Amazon page and also as in their owner's manual.Con's: It's a little bit noisy, but not so loud that hearing protection is desired. I imagine a gasoline-powered pressure washer, if it were a whisper-quiet 4-stroke motor, might be quieter. But a two-stroke gasoline pressure washer would be far too loud, and I'd have to wear hearing protection.The power cable supposedly can be manually coiled & hung from a large plastic hook. I don't find that efficient. A retractable / spring-loaded retrieval coil / reel for the power cable would be an improvement, but this is merely cosmetic. If the vendor had provided a nice Velcro cable management strip, it would easily deal with the loose power cable that tends to come loose and drag or fall on the ground when the unit is tipped to roll on its wheels.The reel used to roll up the sprayer's hose is stiff to turn, no matter whether pulling hose out or reeling it back in, and the reel's fold-out handle is too short to provide sufficient leverage to enable a person to easily and quickly roll up the hose.The wheels upon which the washer can be towed are stiff to turn. Not so bad that they don't turn, but they are a bit stiff. Perhaps they'll wear in, or perhaps I'll try a bit of lubricant on their axles.The manual says to only use water or the manufacturer's liquid soap. I'd like the option of using any liquid soap--perhaps Dawn dish washing liquid--but I'll stick with only water for now, and will purchase some of the SunJoe liquid soap and see how I like it. If it's expensive or smells harsh or doesn't do a good job, I'll stick with water. But I count it as a "con" that the manual states I shouldn't use anything but the one recommended soap, which SunJoe makes.As with any pressure washer, it's possible to damage what you're spraying if you choose the wrong nozzle, or get the nozzle too close to the surface being sprayed, or leave the spray on one spot for too long. Follow the instruction manual and test cleaning places that aren't conspicuous, so you don't make mistakes everyone will see. Softer material, like wood, can be over-sprayed, or sprayed too harshly or slowly, resulting in wood between growth rings being etched away. Don't use too powerful a nozzle, and don't spray too close to the surface being cleaned.For others who may remark that their sprayer has too much noise AND has no pressure, it's likely their garden hose isn't complete clear of air bubbles. That may be the sole thing I'd wish to be different--the pressure washer doesn't run properly if air bubbles get into it. It's VERY simple to correct the problem, though; just turn the power off and hold the trigger down until all the air has run through the hose and out the spray nozzle. Every other electric pressure washer I've owned had this same issue, and it's just a matter of training to remember to hold the trigger open while the water is turned on and the electric is turned off, until no more bubbles come out. It takes time, though--particularly if you have a long garden hose that has a lot of air in it.Remember this pressure washer is not compatible with hot water. I have a 125' black rubber 3/4" garden hose, and the water within it gets almost boiling hot when the hose sits in the sun. Be sure to run all that hot water out of the hose before connecting it to the washer, so only cool water is being supplied.The four stars are for the wheels being stiff to turn, and for the hose reel being difficult to use to take up the pressure washer's hose. If both of those had been as I expected--easy and efficient to move the washer and roll up its hose, I'd have given five stars. And perhaps as I use it more, the hose reel and washer wheels will break in and begin working perfectly, instead of only acceptably. I'll submit a second or updated review if that happens.For now, I say buy it. Mine works well.I recommend this unit.
