Why You Buy Generac Pressure Washer?

Pressure washers provide up to 75 more times water pressure compared to regular garden hoses. High pressure saves on water, perhaps why you should consider investing in one pressure washer.

However, the wide array of pressure washers makes it challenging to find the best. Even after singling out one brand, the Generic brand of pressure washers, below are additional considerations to look into before purchasing the unit.

1) Water Pressure Strength

It is important to find a powerful unit that suits your needs. This is directly dependent on what you intend to use the unit for. If you will be cleaning regular surfaces such as driveways, patio, and siding, consider settling for a residential pressure washer.

However, if you will be dealing with paint and heavily embedded moss, mildew and built-up muck, consider finding a unit with high GPM and PSI.

2) Unit Price

Price is a varying factor when it comes to pressure washers. Gas powered units range from several hundred dollars to a thousand dollars, depending on its feature set.

A studier unit with large pressure output and cleaning power will definitely cost more compared to a standard washer. Your budget and intended use will determine your selection.

3) PSI and GPM Output

The PSI and GPM are essential terminologies in this sector that you should be well versed with. PSI stands for Pressure on Square Inch while GPM stands for Gallons Per Minute. A large GPM means that water output from the unit is great.

High PSI and low GPM results in a medium pressure washer. A high PSI and GPM is a sign of a very powerful machine.

Important Accessories for Pressure Washers

1) Nozzle Upgrades

Nozzles are important components that you should consider upgrading to get the most from your pressure washer. As mentioned in individual pressure washer reviews, each unit comes with several degrees of nozzle heads.

Most units come with zero degrees nozzle head attached, that shoots high-powered and concentrated water straight at whatever is being washed. Such pressures from the nozzle tip might be too much for other cleaning tasks, and you should consider finding alternatives.

2) Brass Couplers

You should also consider investing in brass couplers and fittings. The metal fittings provided by Generac are of high quality but having brass couplings as backup provides extra safety and security. What’s more, is that the brass couplings are inexpensive and protects your unit pretty well.

3) Rotating Scrub Brushes

You should also consider investing in extendable washing wands. This is important, especially if you want to stay safe and firm on the ground when using the pressure washer. The scrub brushes make it easier to use the unit as they come with 5 or 10ft extra length, eliminating the need of having to use ladders when washing raised areas.

4) Floor Sweeping Units

Adding floor-sweeping units appear as oversized shop brooms and have little rotating nozzles that make it easy to work on dirt, grime, and gunk. Having one or two is not a bad idea as it can handle a wide area at once. You can also clean tight corners and crannies with much ease.

5) High-Pressure Hoses

Lastly, it is prudent to upgrade the pressure hoses provided by manufacturers. As mentioned in the reviews, most products come with between 20 to 30ft long high-pressure hoses.

Whereas they function optimally, you can consider having another high-rated pressure hose, say 500 PSI or more to provide a buffer zone, preventing accidental blow-outs related to high-pressures.

The Bottom Line

Pressure washers save countless cleaning hours and make the entire process easy and simple. Among the many brands available on the market, Generac manufacturers heavy-duty pressure washers that provide powerful washing.

All these industrial designs match their power output, are easy to use and assemble. Since its inception, the company has stood the test of time in terms of quality, performance, and durability in providing outstanding units.
