Zoom on the Briggs & Stratton 20330

The Briggs & Stratton 20330 is a heavy duty, commercial pressure washer, that provides its users with an all-around versatile cleaning experience, and enables:

  • spot cleaning of hard, paintless surfaces and reaching far-away areas
  • intense cleaning of hard, unpainted surfaces
  • cleaning of painted and frail surfaces
  • applying detergent and cleaning solutions

Its power characteristics and design, its main features and all its additional features are presented ahead.

Power

With a powerful 391 cc (13 hp) engine, its triplex pump delivers a pressure of 3700 PSI (roughly 62 times more than a standard garden hose) and a flow of up to 4.2 GPM (values claimed by the manufacturer), resulting in the Briggs & Stratton 20330's cleaning power of 15540 Cleaning Units.

The Vanguard™ engine of this gas-powered pressure washer relies on an old-school pull-start mechanism to get started.

A fuel tank with a maximum capacity of 2.1 gallons is used to store gasoline.

Design & Handling

The Briggs & Stratton 20330 is very mobile, due to its hand truck design and approximate dimensions of L37 x W24 x H32 in. The robust and sturdy steel tubing frame offers longevity to the assembly. The handle adds to the 20330 convenience of transport.

The device weighs 155 lbs and thus, is far from lightweight. Transporting and manually lifting it may therefore pose a challenge. The main contributor to its weight are its 391 cc Vanguard™ engine, the triplex pump and steel tubing frame. However, the unit is manipulated smoothly thanks to its two 12" never-flat wheels, which play a key role in its maneuvrability.

Main Features

The Briggs & Stratton 20330 comes with a spray gun, a wand, a pressure hose, 6 nozzles and a detergent injection feature, which are detailed below.

  • Soap injection: While the device doesn't feature a soap tank, detergent supply is ensured by a siphon hose. The detergent is automatically added to the water when a soap nozzle is connected.
  • Pressure hose: A neat storage for the included 50 ft ⌀3/8" high-pressure hose is facilitated by a set of convenient hooks.
  • Spray gun and wand: A side hook enables you to easily store the included classic ergonomic spray gun and its wand.
  • Nozzles: The following table illustrates the 6 included nozzles, along with the surfaces which they are the most suitable for.

  • Safety: Safety of operation is enhanced by a trigger lock mechanism (which prevents accidental operation) and a thermal relief valve (which helps to prevent internal pump damage).
  • Accessories: Included with the Briggs & Stratton 20330 are also the owner's manual (opens in a new tab) and some basic documentation to get you promptly started, along with several accessories, such as spray gun, pressure hose, oil, soap hose and wand.
  • Emissions: The Briggs & Stratton 20330 is EPA-approved and CARB-compliant. Thus, selling and purchasing this pressure washer is allowed in each of the 50 states, including California.

  • The Briggs & Stratton 20330, with a maximum pressure output of 3700 PSI, has an average pressure output, when considering gas-powered units in $1550 to $2000 price range.
