Pros of the washer

  • The Simpson PS3228 pressure washer has great 3200 PSI pressure and quite big water output of 2.5 gallons per minute. Most of electrically powered washer for homeowners are limited to about 2000 PSI and less than 2 gpm.
  • Honda engines are very reliable and much quieter than most of gas ones.
  • 25 foot anti kink hose made of expensive materials. And believe me, high quality hose is very important when it comes to pressure washers
  • The GX200 5.5 hp motor has pretty low oil shut off, separate fuel/choke controls and a big enough 3.3 qt gas tank. Industrial triplex plunger pump is equipped with ceramic pistons and a thermal relief valve and to lasts for years of trouble free service. A sight gauge on a pump helps to  keep tabs on the oil level.
  • The weight of the SIMPSON PS3228-S is about 85 lb, so most likely you are able to lift the unit by yourself in and out of the van. The work is pretty quiet, even at full throttle and this allows to get started earlier in the day.
  • The washer is compact enough to store in a small garage

PS3228-S Cons

  • For professional tasks 25 feet hose is not long enough and you’ll be moving the unit all the time.  You can pay about $80 for Simpson 50 foot hose.
  • The washer use professional grade ceramic piston Triplex pump. It is high quality and very efficient machine with great output in pressure and water flow. It should work for years and has two year warranty. But it is really expensive, so possibly in a 5-7 years of home use you’ll decide to buy new washer instead of spare pump.
  • The reversible handle is a bit low, if you plan to use it for a long period of time, moving it around might be hard on your back.
  • The vibration sometimes causes the nozzles to fall off the holders, check them from time to time
  • This is a rather expensive machine.


All in all, gas pressure washer is a durable, portable and powerful machine for the money and I would recommend it to others for purchase. Though it’s average in price on the gas washer market, you can choose a cheaper option with slightly worse reliability, pressure and water flow rates if extra $100 plays a big role.

May be, electrical washer is good enough for your needs. Although electric washers are lighter and quieter, they are limited by the current source and the length of the power cord. Also you need to remember, that long cable cuts voltage and unit power. Nevertheless, if you only use the device at home, choosing an electric washer with sufficient power makes sense.
