If you’re cleaning anything with oil or grease, you'll need hot water. Would you use a dishwasher with just cold water? Of course not! It takes hot water to “melt” grease. But, if you’re simply cleaning decks, taking mold off cement, stripping paint, or washing away mud, a cold water pressure washer will work very well.
The answer depends on what you are cleaning. When you have thick, heavy dirt, gallons per minute (GPM), or volume, is more important. If your problem is stuck-on grime, pressure (PSI) is more important. A general rule is that volume is the deciding factor and a quality pressure cleaning system will provide the proper balance of volume and pressure.
A little known fact is that there is more cleaning power in a pressure washer's volume (GPM) than in its pressure (PSI). A pressure washer with 2 GPM and 3000 PSI won't clean as fast as a pressure washer with 4 GPM and 2000 PSI. The first pressure washer delivers 6,000 cleaning units (2 x 3,000) compared to the second pressure washer's 8,000 cleaning units (4 x 2,000).
Direct-drive pumps are smaller and the machines are less expensive. Improvements over the years have substantially extended the life of these pumps even in high-use situations. Belt driven pumps turn at a slower rate (1500 RPM). They have less heat build up and vibration so they tend to last longer.
A garden hose is generally used as a source of water, but a water tank is available for portability.
Yes. Our trucks are stocked for field repairs or you can bring your Hotsy to our shop. We suggest regular oil changes and burner tune-ups two times per year for heavy users. Parts that wear, such as belts, nozzles, and hoses, also need to be replaced periodically.
The 9400 Series changes a cold water pressure washer into a hot water pressure washer by attaching a heating module.
