Key buying factors
Opt for a unit with at least 2000 PSI and 1.4 GPM for most tasks; higher GPM cleans faster with less water.
Brushless induction motors last longer and run cooler, improving energy efficiency and reducing maintenance.
A longer, kink-resistant hose and quick-connect nozzles improve usability and reduce water waste.
Total Stop System shuts off the motor when the trigger is not pulled, saving electricity and extending pump life.
Compact, lightweight models with wheels and onboard storage are easier to move and store.
Look for metal pump heads and robust frames; longer warranties indicate confidence in durability.

Drain water and store indoors below freezing; add antifreeze for pumps if needed.
Check and rinse the water inlet filter monthly to prevent clogs and maintain flow.
Run clean water through the system for 1-2 minutes after using soap to avoid residue buildup.
In our evaluation, the most energy-efficient models combined auto-stop technology with a brushless motor and high GPM, allowing them to clean faster using less water and electricity. We found that a slightly higher GPM often beats raw PSI for overall efficiency.
For maximum water savings, pair your pressure washer with a surface cleaner attachment-it covers more area per gallon and reduces overspray.
