The HydraMaster PEX 500 (56384887) is the heated 12-gallon portable carpet extractor that high-performance commercial carpet cleaners and restoration contractors specify when the work requires truck-mount-class output without the truck-mount footprint. Carpet cleaning specialists, IICRC-certified restoration contractors, and large commercial cleaning companies on accounts with CRI or LEEDS sustainability requirements choose the PEX 500 because it is the highest-output portable extractor in the HydraMaster line and one of the few CRI Seal of Approval Gold certified portables on the market.
Built for
High-performance carpet cleaning specialists running production schedules on commercial accounts. The 12-gallon solution tank and 10-gallon recovery let the operator clear full hotel-floor and large-office runs between fills, and the 200-inch water lift leaves the carpet damp-dry rather than wet for fast turnaround.
IICRC-certified restoration contractors on water-damage extraction and carpet remediation jobs. The 50-500 PSI adjustable pump and 2000W heater handle Category 1 to Category 3 water extraction protocols and the post-extraction restoration cleaning that follows.
Commercial cleaning companies on CRI- and LEEDS-spec accounts where the cleaning equipment itself has to carry environmental and performance certifications. CRI SOA Gold is the highest-tier carpet cleaning equipment certification and LEEDS eligibility opens the equipment to LEEDS-spec contracts.
Tile and grout / hard surface contractors who pair the PEX 500 with a spinner-style hard surface tool. The 500 PSI maximum is enough pressure for typical commercial tile and grout work, and the dual 3-stage vacuum recovery handles hard surface water volume without trailing water across the floor.
Heated 50-500 PSI cleaning
The PEX 500 pairs a positive-displacement adjustable 50-500 PSI pump with a 2000W two-stage heater. The pump's wide adjustment range covers three different work modes: low-pressure carpet (50-150 PSI), standard commercial carpet (200-300 PSI), and hard surface tile and grout (400-500 PSI). The heater offers two settings: high (212 deg F at the heater output) for carpet cleaning, low (145 deg F) for upholstery where higher temperatures risk fabric damage.
Dual 3-stage vacuum recovery
Two 5.7-inch 3-stage vacuum motors run in series to produce 200 inches of water lift. That is genuine truck-mount-class recovery in a portable package, and it is what makes the PEX 500 capable of leaving carpets damp-dry on production runs that would defeat lighter portables. The in-series configuration multiplies the lift through the second-stage motor rather than adding flow capacity.
CRI Gold and LEEDS
The PEX 500 carries the Carpet and Rug Institute Seal of Approval Gold certification - the highest CRI rating for carpet cleaning equipment. CRI Gold also confers LEEDS eligibility, which matters on commercial accounts with sustainability requirements written into the cleaning contract. Many institutional and corporate accounts now specify CRI Gold equipment as a condition of bid.
Body and portability
The PEX 500 weighs 110 pounds with empty tanks and measures 39-inch H x 25-inch W x 33-inch L - compact enough to fit through standard commercial doorways and load into a service van. The 12-inch non-marking wheels handle stairs and rough flooring, and the ergonomic handles balance the unit for stair lifts.

Frequently asked questions
What does CRI Gold certification mean?
The Carpet and Rug Institute Seal of Approval Gold (SOA Gold) is the highest CRI certification level for carpet cleaning equipment. CRI Gold certifies the machine for soil removal, water extraction, and texture protection performance under standardized test methodology. CRI Gold also makes the equipment LEEDS-eligible, which matters on commercial accounts with sustainability requirements written into the contract.
What is the practical difference between high (212 deg F) and low (145 deg F) heat?
High heat (212 deg F at the heater output) is for carpet cleaning where heat is the difference between dissolving protein and oil-based soils versus rinsing them. Low heat (145 deg F) is for upholstery where higher temperatures risk damaging fabric backing or fading dye. The two-setting heater lets the operator switch between carpet and upholstery work without buying two machines.
Why a 50-500 PSI adjustable pump?
The wide pressure range lets the PEX 500 handle three different applications: low-pressure (50-150 PSI) carpet extraction for delicate fibers, mid-pressure (200-300 PSI) carpet for typical commercial work, and high-pressure (400-500 PSI) for hard surface tile and grout cleaning when paired with a spinner-style hard surface tool.
Is the PEX 500 a truck-mount or a portable?
Portable. The PEX 500 is HydraMaster's high-performance portable - a 110-pound unit with dolly wheels and ergonomic handles that can be loaded into a service van and rolled into a job. For larger commercial or fleet work, HydraMaster makes truck-mount slide-in systems.
What replacement parts are commonly stocked?
Vacuum motor brushes, pump seal kits, heater service parts, and recovery tank float assemblies are the most common service items. We stock the standard service parts and can source any HydraMaster part not in regular inventory.
