Does lowes carry the adapter you can put on your garden hose to use it as a pressure washer? Also does this thing work good, anyone used it? Thanks.
Answer
Pressure washers INCREASE the pressure of the water entering the washer by means of a HIGH PRESSURE pump. Nothing that does not reach similar pressures will have the same effect.
(Pressure washers usually operate up to 1500 - 3000 PSI, up to 15 - 30 times Household water pressure.)
There are a few items that use compressed air to additionally pressurize the water, but they require a separate air compressor and a second hose and never reach really high pressure. (These can discharge at up to about 250 PSI, up to about 2 1/2 Times Household water pressure.)

These are usually only used in industrial applications where compressed air is already available.
I am assuming that this is the sort of item you were looking to find.

This type of item DOES NOT increase the pressure coming into the device,
it merely maintains more of that pressure and hence has a somewhat increased force to the stream of water coming out of the tip, by simply reducing the size of the orifice (hole) at the end of the nozzle. (Household water pressure is usually under 100PSI.)
There are quite a number of common nozzles that achieve much the same effect at a much LOWER COST.
The Adjust-a-Power nozzle is a common one widely used by forestry fire fighters, and car washes.

You may even find this type of nozzle at Lowes, Home Depot or your local hardware store.
An even cheaper unit to try that is sure to be available at Lowes, Home Depot or your local hardware store is a SWEEPER nozzle. Which has a smaller orifice than a regular Garden Hose Nozzle, but larger than the Adjust-a-Power nozzle.

Keep in mind that when the orifice is smaller LESS water comes out per minute (or per hour) if you are at the same pressure, so with these devices if the water is doing the real washing it may take significantly longer to achieve the effect you want as well.

Is this better then a typical pressure washer for my deck and patio?

HUSKY 3-IN-1 HI-Speed Pressure Washer
Answer
Not necessarily, and here's why: The rotating head on the unit shown has a nozzle in it that shoots out a pinpoint jet of high-pressure water. That high-pressure jet is strong enough to bore into wood. So, what you'll likely end up with is a bunch of circles etched into the deck surface.
A standard pressure washer has a nozzle at the end of the wand that adjusts from a pinpoint spray to a wide, flat spray. This wide spray is what you use for wood decks, because it's not strong enough to bore through the wood, but it is strong enough to blast off anything on the surface.
I got the Husky 1800 PSI electric power washer at Home Depot a couple uears ago for about $180. I originally got it to clean the eaves of my house before painting and it worked great. I also used the pinpoint spray to remove some old paint from a concrete surface. But, that pinpoint spray would have damaged the wood.
