Choosing from the vast amount of power washers isn’t easy so make sure you read this information to find the best power washer for your needs. Don’t be intimidated by all of the terms and specifications, but recognize what facts you need to know to make a good business decision. The most important thing to know about power washers is they must match the work you intend to do. Some power washers can be too large or powerful then you have wasted money and you could damage what you are cleaning. If you’re not careful you may end up buying too many power washers because they are too small for your needs, it will also take too long to do the work and you will lose money. That is the simple truth lg washer repair pasadena.
Let’s start by looking at the different choices you will have to make when buying power washers:
1. Gasoline vs Electric power washers
2. Hot Water vs Cold Water power washers
3. PSI vs GPM vs CU
4. Belt Drive vs Direct vs Gear Driven power washers
5. Portable vs Stationary power washers
6. Wobble vs Axial vs Camshaft Pump
7. Heavyweight vs Lightweight power washers
8. Home Model vs Contractor Model power washers
Gasoline vs Electric: Most power washers are either powered by an electric motor or a gasoline engine. A few are diesel powered. Electric power washers require little maintenance and are very quiet. They require a source of power nearby (because the cord length is limited). They can be used indoors without any problem. You can have electric power washers with lots of power, but most electric power washers are small units designed for specific jobs, such as mobile detailing or deck cleaning. Gas power washers, on the other hand, can be extremely portable. They are designed for outdoor use and can be built to deliver tons of cleaning power. They can be somewhat loud, but your customers expect to hear some noise while you are working. Gas-powered power washers are used for cleaning concrete (called “flat work”), deck cleaning, fleet work, kitchen hoods and ducts, or any other power washing job that requires portability.
Hot Water vs Cold: Most power washers are cold water portables. Cold water, along with the right cleaners, can do most jobs. Some jobs, like removing heavy grease or stripping off finishes, just go better with hot water power washers. Hot water power washers will enable you to cut about 30% off the time it takes to do ANY job. The power washing business is all about time, not spending less on your tools. If you have the right tools, you can compete with other contractors and get done with each job in the shortest amount of time. Many new power washing contractors make the mistake of under-buying their tools to save money. Most experienced power washing contractors over-buy their tools and make the difference back in no time with the added power and features. If all you are going to do is clean and seal wood, just buy one of the cold water power washers. If you are washing anything else, such as houses or hoods or trucks or concrete, consider one of the hot water power washers. If you already own a cold water power washer and want to have hot water, you can call us and buy a “hot box” which will heat the water coming out of most cold water power washers.
PSI vs GPM vs CU: First of all, let’s explain the acronyms. PSI stands for Pounds per Square Inch. This is the pressure rating used to rate power washers. GPM stands for Gallons Per Minute, the flow rate of power washers. CU stands for Cleaning Units, which is PSI multiplied by GPM. All of these terms refer to the power put out from power washers.
To clean effectively, power washers must provide ‘agitation’ to scrub off the dirt and ‘flow’ to rinse it away. Think of the pressure (PSI) as the agitation that is applied to the surface that you are cleaning and think of the flow (GPM) as the rinsing force that carries the dirt away.
Homeowner’s power washers tend to run between 1200 and 2700 PSI. Contractor-grade power washers tend to run between 3000 and 5000 PSI. More power means faster work, but more power also means more potential for surface damage. Wood decks, for example, are often cleaned at pressure as low as 300 PSI because 3000 PSI will rip the wood to shreds. Most contractors will settle for 3000 PSI because that amount of pressure is adequate for most jobs. Truth is that most contractors would prefer to have 3500 or even 4000 PSI if they could get it.
GPM is much more important to most contractors than PSI. Since most contractors use cleaning chemicals to do most of their power washing work (the fastest method) their job becomes one primarily of rinsing rather than washing. The cleaners do all of the cleaning, and the contractor rinses the dirt away. When you think about that method, you realize that the more flow you have, the faster the job is rinsed. Therefore, most experienced power washing contractors recognize that GPM is more important to them than PSI.
