PRODUCT DETAILS
Benefits
- Serious recovery power: Dual 3-stage vac motors deliver up to 185" of water lift for faster drying and better soil removal.
- Built-in heat where it matters: 1750W in-line heat boosts cleaning performance on greasy traffic lanes and heavily soiled areas.
- Wide pressure range: Adjustable 50–500 PSI lets you stay gentle on upholstery or push harder on trashed commercial carpet.
- Work longer between refills: Full-size 15-gallon solution and 15-gallon recovery tanks reduce downtime.
- Made to take abuse: Durable roto-molded construction and non-marking rear wheels for real-world use.
Best for
- Commercial carpet cleaning (offices, apartments, churches, retail, restaurants)
- Heavily soiled traffic lanes where heat + strong recovery make the difference
- High-output maintenance programs that demand fewer refills and faster dry times
- Detail work when paired with an upholstery tool (vehicles, chairs, cubicles, stairs)

- In-line heat: Helps break up oily soil and improves rinse effectiveness.
- 500 PSI capability: Gives you the option to run higher-flow tools and tackle severe soil when needed.

- Stable, easy to move: 4" front casters + 12" rear non-marking wheels.
FAQ
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.

Let customers speak for us
from 102 reviewsItem came well packed and arrived on time with updates throughout the process.
We received our Austrian crb and we're using since and it's a must have machine for every carpet cleaning business. Thanks for your fast shipment. You guys are awesome.
I got tired of underperforming machines marketed for residential use and purchased this unit because it was less than half the price of competitors with the same function/power. The unit arrived quickly and was easy to assemble. Day one I cleaned a wool lounge chair, mattress and two sofas and all came out looking good as new.
We've used this product for years when we started our services for VLM Carpet care. It's the best out there and the price is awesome with this company. Note, it does not ship from their office in Battle Creek. It ships from the manufacturer in South Carolina. No worries though, shipping was still lightning fast.
