The gas powered pressure washers generally supply higher pressures than the electric ones, but they are more expensive, require more maintenance, and are very heavy. I wanted a unit that I could carry around by hand and transport it easily to other locations. This unit had good reviews and was rated at 1900 psi, a high pressure for an electric pressure washer. I have had this product for over a year now, and it is still working well. I have used the unit to power wash my deck, the entire siding on my house, my daughter's deck and lattice work, my concrete driveway (before staining/sealing it), my concrete sidewalk (before repairing it), my truck (on a regular basis), my travel trailer, garbage cans, bird baths, and probably a few more things that I may have forgotten about. One of the biggest problems with this product is that it leaks. I almost gave it a 4-star rating because of this problem, but I have used this pressure washer successfully for so many things and have overcome the leak problem, so I gave it 5 stars. The unit itself has a male fitting for water inlet, so you can not connect a garden hose directly to it. Instead, they provide a plastic fitting with female joints on each end and a filter in between. I was unable to stop it from leaking badly with this connection, so I purchased a Gilmour 7FHS7FH Double Female Swivel Brass Connector, 3/4-Inch by 3/4-Inch, sold by Amazon, and used this to connect the unit to a garden hose. I then leave the double female brass connector on the pressure washer all the time, and connect the garden hose to it when I need to use it. This connection solved the leak problem for the most part, although there is still a constant slow drip most of the time -- not much of a problem since you are using it outside. Another thing you may want to consider is how much pressure do you need for the job you want to do. If you want to strip all the paint from a deck, this unit may not be suitable. When I used it on my daughter's deck, it removed all of the loose paint and then some, but did not remove all of the paint (okay for our purpose). When I used it on my deck, I just wanted to clean it up before re-staining, and it worked fine for that. While it cleans my truck well, it does not remove all of the brake dust from the hub caps. My unit, purchased 1 1/2 years ago, came with two lances, a turbo lance and an adjustable lance. The turbo lance spins the spray jet, while the adjustable lance can focus the jet from a point to a broad fan-shaped spray. I used the adjustable lance most often because it provided more pressure, and most of the time I would use it in a fan spray. I purchased an older house about 1 1/2 years ago and it had green algae particularly on the north side of the white house. When the siding was power washed (using the fan spray of the adjustable lance) the green cast on the house turned white, so you could easily see what was cleaned and what was not cleaned. It was necessary to hold the end of the nozzle a few inches (3-6 inches the best to my recollection) away from the siding in order to wash off the algae. This means that the width of the spray band hitting the house was narrow, so it took quite a bit of time to clean the whole house. A more powerful gas powered pressure washer would likely to be quicker. On the other hand, this electric unit was very light weight, and I could easily carry it around the house with one hand (it has a handle at the top). In order to reach the peak of the house, I placed the unit on the support near the top of a step ladder, held it on with a bungee cord, then climbed an extension ladder with the gun in hand to reach the peak. I point this out only to demonstrate the portability of this unit. You could not do this with a heavy gas powered pressure washer. The unit also comes with a soap dispenser. Just place a little liquid detergent in the container, fill it with water, connect it directly to the gun (in place of the lance) and spray it on your car or truck. It lasts maybe 10-15 minutes until the soap runs out, enough time to soap up your vehicle. Then switch over to a lance and power wash it. While the unit comes with a hose reel, I find it just as easy to wind up the hose by hand, tie it with a shoe string and set on top over the handle. I do the same with the electric power cord. Make the loops small enough so they don't slide down over the unit and you have one neat package that you can pick up by the handle and carry around. This is a good, fairly powerful, relatively inexpensive, lightweight, reliable power washer that has served me well.
