Buying Guide

Match PSI and flow requirements

Confirm your pressure washer’s PSI and GPM are compatible with the attachment—several items in this list reference 3400 PSI capability or universal quick-connect fittings

Choose the right cleaning head

Surface cleaners (11–16.5 in) deliver even coverage for decks and patios, while undercarriage cleaners and water brooms are better for vehicle undersides and large flat areas

Check connection type

Look for quick-connect compatibility used by brands like Westinghouse and Greenworks to ensure the accessory fits your spray gun

Consider foam and soap options

Foam cannon or soap kits increase detergent contact time for car washing and siding, helping reduce manual scrubbing

Assess build and replaceable parts

Metal drive shafts, replaceable nozzles, and durable skirts extend service life—prioritize accessories with straightforward serviceability
