What is the difference in one table?
| Term | Water temperature | Source |
|---|---|---|
| Pressure washer | Room temperature | Angi, Best Buy |
| Power washer | Heated, described as steaming hot | Angi, Best Buy |
What does Angi say?
Angi says power washing uses hot water while pressure washing uses regular-temperature water. It also lists typical professional prices: pressure washing starts at $100 and power washing starts at $250.
What does Best Buy say?
Best Buy describes a pressure washer as room-temperature water and a power washer as steaming hot water, and says hot water helps with tough substrates and bacteria. It gives no numbers.
Why do people use the terms interchangeably?
Retailers and contractors often use them as synonyms. Products sold as power washers may be cold-water units, and the distinction we cite is a common trade convention rather than a formal standard. The sources we fetched do not cite a formal standard.
How should you shop?
- Ignore the word and read the spec sheet.
- Check for PSI, GPM and whether the unit heats water.
- Confirm the temperature rating for hot-water machines.
- Compare prices: heated units cost more, as we explain in hot vs cold water.
What should you ask a contractor?
If a professional quotes power washing, ask whether they use heated water and what PSI and GPM the machine delivers. Angi’s starting prices suggest heated washing costs more. A quote should specify the surface, area and method.
Which do you need?
For decks, driveways and cars, room-temperature water is enough. Use heated water for grease. Our hot water guide explains models and safety. For cold-water options, see our electric picks.
What are the cost differences?
Angi lists cold washers at about $100 to $1,000 and hot washers at $1,000 and above, and professional services follow a similar pattern.
A simple checklist
- Read the spec sheet, not the label.
- Decide whether you need heated water.
- Compare buy, rent and hire costs.
- Check safety guidance for hot water.
- Ask contractors what equipment they use.
How do professional quotes differ?
Angi lists starting prices of $100 for pressure washing and $250 for power washing. The gap reflects the extra equipment, fuel and time involved in heating water. A written quote should say what is included: surface type, area, chemicals and whether heated water is used. If a company advertises power washing but describes a cold-water machine, ask them to explain what they mean.
Does hot water always give better results?
Best Buy says hot water helps with tough substrates and bacteria, but it does not fix everything. Some surfaces, such as wood and glass, can be damaged by heat, as Angi notes in its hot versus cold comparison. For general cleaning, the right detergent and nozzle often matter more than water temperature.
How do PSI and GPM fit in?
Neither term tells you how strong a machine is. PSI shows the force at the nozzle, and GPM shows how much water flows. Multiply them to get cleaning units, which help compare machines. Read our PSI vs GPM guide for the details. A hot-water machine with low PSI can still be weaker than a cold-water machine with higher PSI and flow.
What should you do with this information?
When you shop, read the spec sheet and ignore the marketing label. If you want a machine that heats water, look for a stated temperature rating and a burner or heating coil. If you need a general-purpose washer, choose on PSI, GPM, weight and warranty. Our cost guide helps set a budget, and our driveway guide matches machines to jobs.
If you are hiring a contractor, get two quotes and compare what each includes.
