The BE Pressure B4013HJS is a contractor-grade gas pressure washer built for commercial cleaning crews, fleet wash operators, concrete contractors, and property maintenance pros who need real cleaning power day in and day out. Powered by a Honda GX390 commercial engine driving an industrial AR triplex pump at 4,000 PSI and 4.0 GPM, it pushes through baked-on grease, paint prep, equipment wash, deck stripping, and heavy concrete cleaning where homeowner-grade washers stall out.
Who buys this machine
The B4013HJS is the workhorse spec for crews that bill for cleaning hours: mobile pressure-washing services, multi-family property managers, municipal fleet shops, oil-and-gas yard wash, and restoration contractors. Honda GX390 reliability is the reason it stays on this list - operators report multi-year run times with routine oil changes and pump care, and parts availability for both the engine and the AR pump is excellent through the BE dealer network.
Top use cases
- Fleet and equipment wash - removes road grime, diesel film, and red mud from trucks, trailers, skid steers, and tractors faster than 3 GPM machines.
- Concrete and flatwork cleaning - paired with a 21-inch surface cleaner attachment, the 4 GPM flow keeps surface cleaners spinning at full speed for even, streak-free passes.
- Paint and stain prep - 4,000 PSI strips loose paint, mildew, and weathered stain from siding, decks, and fences before re-coat.
- Graffiti and gum removal - high pressure with a hot-water trailer or chemical injection pulls gum off sidewalks and graffiti off block walls.
- Agricultural and dairy wash-down - sized for milking parlors, hog barns, and equipment yards where reach and flow matter more than fine-finish detail work.

Frequently asked questions
Is 4,000 PSI overkill for residential cleaning?
For homeowner driveways and house wash, 4,000 PSI at 4 GPM is more than residential-grade. The right answer for soft-wash or vinyl siding is to step down to a 25deg or 40deg fan tip and increase distance, or use the soap nozzle at low pressure. Where this machine earns its keep is the sustained flow and pressure that finishes commercial concrete and fleet jobs in a fraction of the time of a 3 GPM unit.
How does the AR triplex pump compare to belt-drive vs direct-drive cat pumps?
The AR triplex on the B4013HJS is a direct-drive industrial pump. Most operators run them 800-1,200 hours between rebuild kits with proper oil changes and frost protection. AR pump rebuild kits are inexpensive and well documented, which keeps long-run cost of ownership in line with belt-drive options without the belt and pulley maintenance.
Does it work with a hot-water reel or skid?
Yes - operators commonly run this unit through an inline burner skid for hot-water output up to about 200 deg F, which is the standard rig for grease, oil, and graffiti work. Confirm the burner skid's max inlet pressure rating matches before connecting.
What surface cleaner size pairs with 4 GPM?
A 21-inch or 24-inch surface cleaner is the right pairing for 4 GPM at 4,000 PSI. Smaller 16-inch units do not let the machine work to its capability; 30-inch units may starve at this flow rate and leave streaks.
Cold weather storage tips?
Always pump-saver or anti-freeze the AR pump before any below-freezing storage, drain the float tank if equipped, and run the engine dry of stale fuel or treat with a fuel stabilizer. Frost cracks on the pump head are the most common preventable failure on gas pressure washers.
