DR Pressure washer ES-3100

If you’re a homeowner you probably know how quickly dirt and muck can accumulate on driveways, decks, fences, and sidings. These are tough cleaning jobs, often requiring the muscle of a high-quality pressure washer to be done quickly and efficiently. Therefore, it’s not surprising that the global pressure washer market is valued at around $1.8 billion, and is expected to grow significantly over the coming years.

Now, you may be thinking that purchasing a pressure washer is quite a simple and straightforward decision. However, if you’re buying one for the first time, you’re in for quite a surprise. You see, pressure washers come in a variety of shapes of sizes, and depending on the application, there’s a multitude of factors you need to consider, such as portability, pressure range, attachments, and more.

To help you make the right decision, the experts here at DR Super Store have put together a comprehensive guide to choosing the right DR pressure washer.

Pressure Washers: How They Work and the Different Types

Also referred to as pressure cleaners and power washers, pressure washers are basically outdoor cleaning machines which use an electric motor or a gas engine to pump water at a high pressure via a hose and spraying nozzle. Pressure washers provide efficient cleaning power for applications where a regular garden hose just doesn’t cut it.

There are two primary types of pressure washers:

  • Electric Pressure Washers: Typically the more affordable of the two options, electrical power washers are preferred by most homeowners. Most models can be turned on with just a flick of a switch, are much lighter, and run much cleaner and quieter than their gas-powered counterparts. Electric pressure washers are suitable for light-to-medium duty applications, such as cleaning vehicles, decks, sidings, and patio furniture.
  • Gas-Powered Pressure Washers: If you want maximum power and portability, gas-powered pressure washers are the ideal choice. Depending upon the model and the specifications, these either have a manually-operated starter, or a push-button electric starter.

Now that we’ve discussed the two main types of pressure washers, next up are the different factors you need to consider before making the final purchase decision.

The Pressure Output

When assessing a pressure washer, the first thing you should consider is its power or pressure output. Measured in GPM (gallons per minute) and PSI (pressure/square inch), the pressure output of a machine determines the type of jobs it can handle.

A pressure washer with higher GPM and PSI ratings will clean more quickly and thoroughly, but is likely to cost more than units with lower pressure outputs.

  • Light Duty: Light-duty pressure washers offer a pressure output in the range of 1300 and 1900 PSI with a GPM of 2. These lightweight, compact machines are suitable for cleaning vehicles, grills, as well as patio furniture and small decks.
  • Medium-Duty: These are more powerful, sturdier units which offer a pressure output in the 2,000 – 2,800 range and a GPM between 2 and 3. Since they are perfect for applications, such as cleaning fences, exterior sidings, and walkways, they’re an ideal choice for shop and homeowners.
  • Heavy-Duty: These pressure washers produce pressure outputs in excess of 2,800 PSI with a 3-4 GPM. Since they’re so powerful, these commercial-grade machines are typically used for large-scale cleaning tasks, such as paint stripping and graffiti removal.

Hot Water/ Cold Water

When choosing a DR pressure washer, you’ll also notice that some units are “hot-water models”, while some are “cold-water models.

  • Cold-Water Pressure Washers: When it comes to DIY home use, cold-water pressure washers are the more popular choice. They’re significantly more affordable than cold-water washers, and are ideal for applications such as cleaning vehicles, removing mildew, loose paint, and dirt buildup.
  • Hot-Water Pressure Washers: These are mainly used for farming and industrial applications. Hot-water pressure washers are generally complicated to operated and expensive. However they utilize less cleaning chemicals and detergent, and are quicker and much more efficient at cleaning.


Portability is next on the list of factors you need to consider. How portable do you need the machine to be? If you’ll only be using it to clean a small area, an electric pressure washer would be the ideal option – like we’ve mentioned above. These need to be plugged into an electrical outlet, and thus, feature a wire – which means you can only wander as far as the length of the wire allows.

However, if you’re buying a pressure washer to clean a larger area, you’ll need a washer that can be move around easily. This is where gas-powered pressure washers hold an advantage. Powered by a small internal combustion motor, these machines don’t feature any wires or cables – which means you use them wherever you want.

Attachments and Accessories

Another factor you’ll have to consider when choosing a pressure washer is the type of attachments and accessories it’s compatible with. Different DR pressure washers come with different cleaning tools and accessories that enhance its cleaning power for various applications. For instance, if you’re buying a DR pressure washer to scrub away dirt and grime quickly, you want a one that’s compatible with a Turbo Nozzle. This high-pressure rotating jet can reduce cleaning time by up to 30%.
