VEVOR Pressure Washer Telescoping Wand, 24 ft, 4000 psi, Telescopic Spray Wand with Power Washer Extension Wands, Gutter Cleaner, Brush Head, Pivoting Coupler, 7 Spray Nozzles and Support Harness

The minimum water pressure that will work with this wand is 2000-4000Psi If this answer doesn't resolve the current issue, please reach out to us again for assistance.

Yes, it will work with the Sun Joe SPX3000, but you may need adapters for the fittings, and you should use moderate pressure settings for safe operation.

The wand connects to the harness using a support hook/clip system: the wand has a mounting bracket that locks into a holder on the shoulder harness, so the harness carries the weight while the wand slides/adjusts freely.

It can not work with a hot water pressure washer.

It fits your 1500 psi A R Blue pressure washer.
