Why You Need a Pressure Washer
- More Effective Cleaning: a pressure washer generates more water pressure and water flow than a garden hose. With a power washer you don’t need to scrub the floor or your car to remove dirt.
- Cleans Large Areas: a pressure washer can clean driveways, walls, and in the case of commercial grade pressure washers, construction sites and parking areas.
- Easy to Use: pressure washers are easy to use: you just hook up the hose on the water unit, power it up and begin spraying.
- Reduces Cost of Repair: too much grime and dirt can weaken a building’s structure as it traps moisture. Too much moisture leads to mildew and other problems. The situation is even more serious with vehicles, as dirt buildup in critical parts can lead to accidents.
- Saves Time: regular garden hoses takes too long. However, you only need a few minutes to do the job. Even on a dirty ATV, it shouldn’t take that long to clean.
- Provides Protection: high temperature and too much sun exposure may damage the structure. With regular washing you’ll be able to counter those effects effectively.
- Works on All Surfaces: pressure washers work on wood surfaces, concrete and just about any surface. With high enough psi, you’ll be able to remove dirt, oil deposits, mold, moss etc.
Gas vs. Electric Pressure Washers
- Electric Pressure Washers: electric pressure washers are suitable for vehicles, outdoor furniture and small projects. Electric pressure washers weigh less than their gas counterparts and you turn them on by flipping a switch.Depending on the design, an electric pressure washer may have to be plugged into a power source directly, or an extension cord may be needed. Follow the instructions in the user guide to avoid accidents.
- Gas Pressure Washers: gas pressure washers often have more power than electric pressure washers. This makes them more suitable for heavy jobs like large patios, exteriors of multi-story buildings and decks. Gas pressure washers are also portable because they don’t rely on an electrical cord.Some gas pressure washers have an electric starter, but most are manually started. Gas pressure washers have to use the proper fuel, so follow the instructions on the manual.
- Commercial Pressure Washers: these are made for commercial and industrial applications, though they can also be used in large households. They have larger hoses, more powerful engines, bigger motors and more powerful pumps than standard gas and electric pressure washers.
What to Look for in a Pressure Washer
- PSI (Pounds Per Square Inch): this determines what type of jobs the pressure washer can handle.
- 2000 PSI and below: these pressure washers are for light duty use. You can use these to clean boats, trucks, cars, siding and patio furniture. They’re also capable of washing decks, fences, driveways and patios.
- Between 2000 and 2800 PSI: these are medium duty pressure washers. They can clean the same stuff as the light duty pressure washers, but more effectively. Medium duty pressure washers are also more effective on fences, patios and siding.
- 2900 to 3000 PSI: these are heavy duty pressure washers. These are among the most versatile and ideal for large driveways, sidewalks as well as multiple story cleanup jobs. A heavy duty pressure washer also helps ready surfaces for painting.
- 3300 PSI and up: commercial level pressure washers are at this level. These units handle the same tasks as the other washers, but they have more power.
- GPM (Gallons Per Minute): deep cleaning needs high psi, while higher GPM translates to better rinsing and cleaning, which makes it easier to clean hard to reach areas. You need to look at both GPM and psi to determine which pressure washer to buy.
Best Brands that Make Pressure Washers
The higher the GPM and the psi, the more effective and the larger the area it can clean. But you have to consider how you intend to use it. There’s no need to buy a 3,300 psi power washer if you just need to wash the patio furniture.
You may want to look at multi-duty pressure washers for customizable options. You can set the flow rate higher to clean delicate areas or set the psi pressure up for deep cleansing.
Features to Look for in the Best Power Washer
- Power Output: power output on electric washers is measured in amps, while on gas pressure washers it is in cubic centimeters (cc). The higher the numbers the more powerful the pressure washer.
- Pump Types: the most common are triplex and axial cam. Majority of home pressure washers use an axial cam and it’s sufficient for most tasks. Technological advances have led to the development of maintenance free axial cams for easy operation. Commercial and heavy duty pressure washers are equipped with triplex pumps, as they are more efficient and have a longer lifespan.
- Nozzle Tips: pressure washer nozzle tips allow you to change the flow and pressure. The wider the spray, the lower the pressure but the greater the coverage. The narrower the spray, the higher the pressure but with less extensive coverage. Nozzle tips come in different degrees, 0, 40, 20 degrees etc. There are also detergent and soap tips available.
- Wands: an adjustable wand lets you modify the spray pattern from wide (low pressure) to narrow (high pressure) without replacing the nozzle tip.
- You may also want to look for rotating nozzles as it generates a circular spray pattern. This is more powerful than regular sprays and useful for heavy duty jobs.
- Some pressure washers have a detergent or chemical injection so you can use chemicals and other cleaners. These are placed in a siphoning tube or an onboard tank. An onboard tank is the more practical solution if you have to use cleaning chemicals frequently.
- Thermal Relief: a thermal relief system or unloader is designed to lower heat buildup and pressure. It’s normal for pressure washers to generate heat, but too much of it – and pressure – could damage the unit.
Pressure Washer Accessories and Tools
Most models, and not just the best pressure washers, can do the job without the need for extra tools. However, there are some accessories and tools you may find useful under certain situations.
- Extension Wand: an extension wand is used to wash siding, speeding up the cleaning process and produce better results. Combined with spray tips, extension wands make cleaning of second story building easier.
- Pressure washer brushes add scrubbing capabilities, which helps remove stubborn dirt.
- Angled wands may be combined with extensions to clean hard to reach areas like gutters.
- If you clean sidewalks and driveways regularly, you may want to try a spinning jet equipped surface cleaner.
- There is an assortment of detergents, soaps and cleaning chemicals you can use. Be careful and use only cleaning solutions that are compatible with the surface. Wood in particular is sensitive to harsh chemicals as is car paint, so use only what the manufacturer recommends.
Pressure Washer Maintenance
Maintenance requirements vary, though gas powered washers need more upkeep than their electric counterparts. The user manual should have information on the maintenance schedule.
- Do not use a gas pressure washer indoors or any location without sufficient ventilation.
- The exhaust has to be directed away from vents, windows and doors.
- If you’re using an electric pressure washer, keep the electrical connections off the ground, and it must be dry.
Prior to Using a Pressure Washer
- Check the fuel and oil levels before using it.
- Do not overfill, but do top the level.
- Examine the water inlet screen where the garden hose hooks up. Wash with water if the screen is clogged or dirty.
- If the washer has a wand extension inline screen, ensure it is not clogged. Replace the screen if damaged or clean with water.
- Inspect the spray tip, wand extension and spray gun. Ensure the connections are secure.
- Test the trigger lock and spray gun trigger.
- Look at the hose for signs of bulges, leaks, abrasions and cuts. Examine the couplings as well. If there’s damage, replace them. Perform the same inspection for the siphoning tube and unclog if necessary. Clean the filter too.
After Using the Pressure Washer
- Once you’re done cleaning with an electric pressure washer, take out the detergent siphoning tube and set the pressure to low. Allow water to through it for a couple of minutes.
- Turn the washer and water supply off. Unplug from the power source and direct the spray gun away from animals and people. The trigger lock may be engaged when water no longer flows.
- Allow the pressure washer to cool off. Disconnect the hose, and extension, spray gun and the garden hose. Drain the water from the pump. Keep the machine on until all the water has left the pump before shutting down.
- Gas powered pressure washers have specific instructions in the user manual, and you should use that as a guide. Part of the maintenance includes engine oil replacement, spark plug inspection and cleaning the air filter. The fuel system also needs to be taken care of, but the steps vary according to the model.
- Don’t use fuel that is more than 30 days old as they’re prone to varnish and corrosion. Some gas pressure washers recommend a fuel stabilizer to keep gas fresh and stop engine corrosion.
- Both electric and gas powered pressure washers should have their nozzle tips inspected regularly. The connections for the wand extension, spray gun and hose have to be lubricated on a regular basis for optimum performance.
A pressure washer can take a lot of the load off you, but only if you picked the right one. If you’ve never used a pressure washer before or want to replace what you have, it’s necessary to do some research to get the most value for your money. Pressure washer reviews of the individual models come in very handy while you’re doing this research, as it presents all the potential positive and negative points of a model that a beginner might miss at first glance.
As to which product is best, it’s a matter of personal preference and requirements. Electric power washers are easier to maintain, while gas power washers have more power. Of course for heavy duty, daily use, commercial power washers are the best option.
