Cleaning — FAQ
Can these replace a gas pressure washer?
For most homeowners, yes. Modern 1500-1800 PSI cordless models handle cars, patios, and siding effectively. However, gas units still dominate for heavy commercial work and sustained all-day use where power outlets and water are readily available.
How long do batteries last per charge?
Expect 15-25 minutes of trigger time per 4.0Ah battery. Dual-battery kits provide 30-45 minutes total. Actual runtime varies by pressure setting: high-pressure mode drains batteries 40% faster than low-pressure mode.
Can I use water from a bucket or lake?
Yes, but you need a model with self-priming capability and a filter. Tank-equipped units work best for bucket/lake water. Always use a pre-filter to prevent debris from damaging the pump. Never run the pump dry.
What's the minimum PSI for cleaning concrete?
Are these safe for car paint?
Absolutely. Use the 40° fan nozzle and keep the tip 12+ inches from paint. The 1200-1800 PSI range is actually safer than gas washers because lower flow rates reduce risk of forcing water past seals. Always test on an inconspicuous area first.
How do I winterize a cordless pressure washer?
Drain all water from pump, hose, and attachments. Run 30 seconds with trigger pulled to clear residual water. Store batteries indoors at 50-70°F. Add pump antifreeze if storing in freezing temperatures. Remove and clean filters before storage.
