Pressure washers or power washers are devices that are used for cleaning with water pressure. Pressure washers produce a spray of water at very high pressures, which is often needed to get rid of grime, dust, grease and heavy stains.

Pressure washers are classified into different kinds: electric, hydraulic, gasoline-based and diesel-based. They are also classified as hot or cold pressure washers. Pressure washers' efficiency depends upon the PSI (pounds per square inch), which indicates water pressure, and GPM (gallons per minute), which indicates the flow of the water. Higher PSI and GPM means greater power and more pressure.

It is a good idea to seek out other people's opinions before buying a pressure washer. The Internet is a good source of locating product reviews for pressure washers. People who have used pressure washers of a particular model post their opinions about its performance and their experiences in using it. These reviews are negative as well as positive. They highlight both the good points and bad points about the product and also give opinion whether to purchase the product or not.

Reviews about pressure washers contain information about the build, power and the usefulness/performance of the accessories that come with the washer. Sometimes the product may not perform too well, packaging may be poor, there could be a part missing, the after sales service may be poor or the product may have been damaged. However, most people are usually happy about the pressure washer they got and generally give good reviews about it. Reviews are also in the form of value for money and the extent of recommendation. Reviewers also give their opinions as to why they bought this pressure washer in the first place. They also give recommendations as to how to improve the product further.

These reviews are available in special websites meant for reviews. They can also be found at the websites of the manufacturers. These sites also give an overall rating that is based on the collective rating of all the people who have put in their comments. Reviews are a great way for comparing prices and options of different brands.
