Electric Power Washer Expectations

Before undertaking testing, The Hammacher Schlemmer Institute surveyed consumers to learn which attributes are most critical when purchasing a Power Washer. They responded that Cleaning Effectiveness is by far their most important concern, followed by Ease of Use, Features. These attribute rankings were applied to the data collected for this test.

Respondents were also asked which features matter most in a Power Washer. Based on their answers, The Best model must have a handle with a trigger, a powerful water stream, and a long power cord.

The Hammacher Schlemmer Institute then researched the marketplace from a reasonably wide range of competing product and obtained Power Washers that possess these desired attributes and features. Prior to testing, the Institute eliminated from consideration any models that did not have a required attribute or feature or if it had an obvious quality issue. Conversely, if a sample offered a unique benefit that distinguished it from other models, The Institute, at its discretion, may have included it in testing even though it may have been lacking a critical feature or attribute.

Testing Methodology

Testing involved evaluations by Institute analysts. Each Power Washer was tested on different surfaces and was rated for its Cleaning Effectiveness, Ease of Use, and Features.

Cleaning Effectiveness

To assess and compare the Cleaning Effectiveness, each power washer was used in common scenarios; cleaning paint from cement, cleaning car rims, and cleaning house siding.

Analysts then took the average of the scores and determined a final Cleaning Effectiveness score

What to look for in an Electric Power Washer

The Hammacher Schlemmer Institute recommends that you consider these features when shopping for an Electric Power Washer to ensure you will be completely satisfied with its performance:

About Electric Power Washers

A Power Washer is a mechanical device that increases water pressure 10-20 times to clean surfaces faster, more thoroughly, and with much less effort—and water—than using a standard garden hose. A Power Washer is ideal for removing mold, grime, paint, and dirt from large surface areas, such as wood decks, concrete sidewalks and driveways, aluminum siding, and vehicles. It is also ideal for cleaning items with lots of nooks and crannies that may be tedious to scrub by hand, such as patio furniture, chain link fences, shutters, or barbecue grills. The device consists of an electric- or gasoline-powered pump, a high pressure hose, and a trigger gun with interchangeable spray wands. Some units also have a soap tank that adds detergent to the water to help remove stubborn dirt. Commercial grade models are typically gasoline powered, while consumer models usually plug into a standard household electrical outlet.

Before Use

As with any product, customers must read and follow the product's user guide, marking and labeling prior to use.
