Customer Questions & Answers

Does this machine have a place for cleaning agents

I have a 2 story business building made of cement, cement sidewalks and stairs and is this machine powerful enough to take mold and clean things up? I want something that will last for awhile as well. Want to be able to use soap and if you think something else will serve me better please let me know. This is about my limit on price. Thanks
Asked by: Docsee
No, it has a siphon hose only that goes directly into cleaning agent bottle.

Can you adjust how diluted the cleaning mixture becomes when siphoning it through

I would like to know what the water to solution ratio is when it is mixed in the pump, and can that ratio be adjusted to allow more concentration of cleaning solution without adjusting it in the container from which its pumped

3,800 psi 3.6 GPM OHV Engine Triplex Pump Gas Powered Pressure Washer is rated 4.4 out of 5 by 21.
Rated 5 out of 5 by from My Generac I chose this pressure washer for a variety of reasons: Price, power, pump reliability. Price: Unit was on sale @ $750. Power: Power to clean driveways and remove old paint . Reliability: My old axial pump did not have stainless steel pistons and they rusted. This unit has ceramic coated stainless steel pistons. Also, it has a triplex pump which should (in theory) last much longer. This unit is new, but so far I am pleased!

Rated 5 out of 5 by from What a pressure washer I had a craftsman pressure for about 6 years. Junk from the first time I used it.It worked ok but would take 3-4 hours to wash the deck. With this generac only 20 minutes. It will clean anything and everything. The only downfall is the wand is very long! Great for doing your siding but unless your 6 ft 6 you are going to want to buy a shorter lance to wash a deck sidewalk or driveway.Should of bought this years ago. Worth every penny!

Rated 4 out of 5 by from Very happy with the Generac This pressure washer is VERY powerful. I use it to clean my driveway and back patio and it got both surfaces bright and clean without using detergents or degreasers. I have logged over 8 hours with it and cleaned over 1,200 sq ft of surface that had several years of dirt and grime. Pros: tons of cleaning power, unit does not leak, has a large gas tank that limits interruptions, and the lance and gun are sturdy and long enough to reach outer surface of 1st story gutters and siding. Cons: awkward location of pull cord, foot pads leave black marks, screws that attach hose holder to frame are too long and do not work. Highly recommend.

Rated 5 out of 5 by from Excellent Pressure Washer Very easy set-up! Basically unbox, read instructions (2x), add oil, fuel, and start (2nd pull). Start was easy and I am 155lbs. Machine runs well, plenty of pressure, and very nice wand - it is long and heavy duty. Probably didn't need this much machine but I like purchasing good equipment and this is very good equipment. Have about 4hrs use on it so far. Only complaint is that on the pump there is the head of a nut near the water hose connection that has taken a chunk out of my thumb twice will tightening the hose - now I wear a glove. It will walk a little on hard surfaces and leave marks if you don't put a towel or rag under the rubber feet. Bought a Surface Cleaner for sidewalks, patio, and composite decking. It is amazing! Be sure to dial pressure back a good bit so it doesn't take off too much of your surfaces, especially decking - dial it way back.

Rated 4 out of 5 by from Solid Machine for bigger jobs Had machine for ~ 3 months at time of review; usage is general home care. Great power for home use, 3.8 GPM helps keep large amounts of material moving. 35 foot hose is nice, a 50 foot house would be perfect. Wish that the unit had a more significant muffler; it's quite loud and you really need ear protection for anything other than short usages. Your neighbors know this is running. Also, it be nice if packaging was a bit more compact - frame provides protection but also makes it big overall. Fold down handle helps. Unit starts reasonably well - key is to be sure to relieve the line pressure after a few pulls. Adjust the above and it gets 5 stars.

Rated 4 out of 5 by from Good pressure washer was on sale for $638.00 at Home Depot Home Depot had a sale on these so I decided to get one, instead of a cheaper home owner unit. This one has triplex pump which is better than the axial pump. My only rant is the mounting looks to be flimsy and cheaply made. I don't think its worth paying full price but if you can get it for around 650.00 then its not a bad deal. You can't run hot water through it either. Would be nice if it came with a 50 ft hose instead of 35 ft. The supplie hose holder is a joke also.
