FAQs

Is this overkill for residential work?
Not if you want faster drying and fewer passes. The real advantage is extraction strength—when you pull more water back out, you reduce wick-backs and call-backs.

Do I need two separate circuits?
This is a dual-cord unit. For best results, plug each cord into a separate 15A circuit to avoid nuisance trips and maintain consistent heat/vac performance.

Can I use it for upholstery and auto interiors?
Yes—pair it with a proper upholstery tool and set pressure appropriately. The wide pressure range is a big plus for switching between carpet and upholstery.

What PSI should I run?
Lower PSI for upholstery and delicate fabrics; higher PSI for heavily soiled carpet when you need more punch. The goal is the cleanest result with the least overwetting.

What makes the Neptune 500H different from cheaper portables?
Productivity and recovery. Dual 3-stage vac + full-size tanks + in-line heat is a combination that helps you clean faster, dry faster, and look more professional on every job.

Bottom line

If you want a heated portable extractor that feels like a real step up—strong lift, real tank capacity, and adjustable performance—the Neptune 500H is built for that. It’s a workhorse platform designed to help you finish cleaner, dry faster, and move on to the next job with confidence.
