The BE Pressure B4213HSCS is a 4200 PSI, 4.2 GPM cold-water gas pressure washer built for contractors, fleet wash operators, and concrete cleaning crews who need a machine that holds up to all-day use. The Honda GX390 engine pairs with a Comet triplex plunger pump on a stainless steel frame - the combination commercial users specify when they want a unit that earns its keep over many seasons rather than one that gets replaced every few jobs.
Built for
This is a workhorse machine for jobs that move beyond what a 3000 PSI homeowner unit can handle. Typical use cases:
- Fleet and equipment wash - trucks, trailers, heavy equipment, and exterior tanks. The 4.2 GPM flow rate is what matters here; pressure alone is not enough to rinse soap and road grime off a long trailer in reasonable time.
- Concrete and parking-lot cleaning - oil stain blasting, gum removal, and storefront sidewalk maintenance. Pair the unit with the optional 20-inch surface cleaner attachment for even, streak-free flatwork.
- Building exterior and graffiti removal - softwash and high-pressure rinse cycles on stucco, brick, and metal panels.
- Restoration and post-construction cleanup - removing dried mud, mortar splatter, and dust from finish work.
- Agricultural and industrial sanitation - barn, dairy, food-processing, and shop-floor washdown where the pump needs to handle hard water.

Frequently asked questions
Is the B4213HSCS rated for commercial use?
Yes. The Honda GX390 is Honda's commercial-grade engine line, the Comet triplex pump is rebuildable rather than disposable, and the stainless steel frame is targeted at contractors who run units multiple days per week. This is not a homeowner machine that has been re-spec'd; it is built for daily commercial use.
Cold water only - can I run hot water through it?
No. This is a cold-water unit. Running hot water (above 140 deg F) through a cold-water pump shortens seal life. If you need hot water for grease cutting and sanitation, look at BE's HW-series hot-water units which include a burner coil sized for the pump.
What is the difference between a Comet pump and an AR pump?
Both are professional-grade triplex pumps used on commercial pressure washers. Comet ZWD-series pumps use ceramic plungers in a forged brass manifold, are widely serviceable, and are the OEM choice on this BE configuration. AR pumps offer a comparable feature set; the practical difference for most users is parts availability through your local dealer network.
What about freight - this is a heavy unit, right?
The B4213HSCS ships as a freight item (curbside delivery on a pallet) given its weight and frame size. Lift-gate service is available at extra cost; if you do not have a forklift or loading dock, request lift-gate when ordering.
How does the surface cleaner attachment fit in?
A 20-inch rotary surface cleaner spins two nozzles inside an enclosed shroud, giving even pressure and roughly 6-8x the productive cleaning rate of a single wand on flatwork. For sidewalks, gas stations, and parking decks this is the upgrade that pays for itself fastest.
How long should a unit like this last?
With basic preventive maintenance - oil changes per Honda's interval, pump oil changes per the Comet schedule, and end-of-season winterization (pump saver or compressed air to clear water) - this configuration is built to log thousands of operating hours. The engine and pump both have field-rebuildable service kits, so even after years of duty the machine is repaired rather than replaced.
What about winter use and freeze damage?
The pump is the part that fails first if you skip winterization. Run pump-saver antifreeze through the inlet at the end of cold-weather use, or evacuate water with compressed air. A frozen pump head is the most expensive avoidable failure on any pressure washer, and it is not covered under warranty.
