Shark Pressure Washers were developed to withstand the most demanding environment – the rental industry – where durability and reliability are tested to the max. The Shark BG-304037 is a high value, belt-driveline pressure washer targeted to the contractor and heavy users. These machines are designed for long running times and in-field use.

Furthermore, the front and rear handles make loading easy and convenient. The Shark BG is the tough, workhorse model of Shark’s rugged, belt-drive, cold water pressure washer line. Powered by industrial-grade Honda gas engines, all five models are certified to the rigid UL-1776 safety standards for pressure washers.
