We've got about 50 units of the GS180NEW sitting in our main warehouse right now, so shippng usually goes out within 3-5 business days unless you're ordering in bulk—then it's more like 10-14 days (check lead time for orders over 20 units).
That 7HP engine actually cranks out 5.0kW at 3600rpm, which is pretty much sweet spot for sustained commercial use without bogging down on tough grime or concrete stains.

The triplex plunger pump is what makes this thing hold up better than most residential-grade units—it's continuous duty cycles, so you're not going to burn through seals after a few months of weekly use.
You get five nozzles in the kit: 0°, 15°, 25°, 40°, and a soap tip, and most buyers go with the 25° for general driveway or equipement cleaning since it balances pressrue and coverage nicely.

Fuel tank holds 3.6 liters, which gives you roughly 45 minutes of run time at full throttle, and the 210cc displacement means it's not a gas guzzler—we usually see about 2.5 hours or so per tank on mixed use.
One thing we don't recommend is using it on delicate surfaces like old wood siding or soft brick—teh 2600 psi will etch those pretty quickly if you're not careful with the nozzle angle.
