                          Review:  Shark SGP- 35037 3,000 PSI                                                   Category: Pressure Washer

Quality of Build

Everything is steel-plated or reinforced by equally-durable components.


A variety of lengths of warranty cover most parts for a reasonable timeframe.

Ease of use

The pressure washer is easy to use, but the range of functionality increases complexity.

Value for money

Though this model is very expensive, you do get your money’s worth.

Things I l​ike

  • Allows the use of cold or hot water
  • Long product warranty on some components
  • Built from durable components and materials

Thinks I don't like

  • Large and cumbersome when it comes to storage
  • Pricier than many commercial pressure washer alternatives
  • Weighs 550 pounds and can therefore be tricky to move around

Who this product is for?

This product is not for the casual user, who needs a pressure washer to hose down their decking or vehicle every few months. 

Additionally, to be blunt, it’s not suited for anyone without a considerable amount of strength, or colleagues to assist in moving the chassis around. At over 300 lbs.,

Karcher advises that your delivery service may struggle to transfer the machine from their van to your premises.

What’s included in the box?

The model comes with the required pump and hosing, as well as the heavy-duty and corrosion-resistant wand that can connect to a wide range of accessories.

Nozzles are included, but additionally, the Shark SGP series pressure washer is compatible with more than 40,000 individual accessories, so you’ll never be short of replacements or additional functionality when you need it.

Features Overview

Speaking of the physical design quality first, the machine comes with a heavy-duty, insulated gun with a fatigue-free handle, as well as 50 feet of wire-braided hosing.

The reliable Honda-manufactured engine is perched on a rugged chassis built from steel, and painted for protection against all types of weather. This chassis is supported by 4 heavy-duty wheels.

The inner workings of the machine also come in an impressive quality. The tires are foam-filled polyurethane for all-terrain maneuverability, and the wand is plated with steel for durability.

The 6-gallon fuel tank is rust-free, and provides hours’ worth of continuous, uninterrupted operation.

Enclosed within its own casing for protection lies a control panel, which gives access to a range of control and functionality, including an automatic thermostat for fine-tuning water temperature, and a burner on/off switch for activating the heater.
