The catch
Westinghouse WPX3400 Gas Pressure Washer
Placing the engine outdoors only is mandatory
Side by side
Westinghouse WPX3400 vs Giraffe Grandfalls Pro compared: Gas power you can move outdoors, or a wash station fixed to the wall
Quick verdict
WPX3400 fits a permitted outdoor job that needs its rated 3400 PSI at 2.6 GPM and a gas-powered setup you can move. Grandfalls Pro fits repeat washing around a fixed 100-foot hose installation with suitable water and power. The gas engine cannot operate inside a garage. Giraffe's 3700 PSI headline sits above its 2700 PSI rated point.
Before you buy
Why, and what it costs you
The bigger PSI in the advertising does not mean the higher-rated machine
WPX3400 specifies 3400 PSI at 2.6 GPM. Grandfalls Pro advertises a 3700 PSI maximum, but its rated point is 2700 PSI at 1.2 GPM. An approved attachment that needs at least 3000 PSI and 2 GPM is cleared by Westinghouse's output but not by Giraffe's rated point. Still check the accessory's upper limits and connectors. Neither specification proves that a particular driveway will take fewer minutes.
Where this comes from
Giraffe's separate 3700 PSI and 1.6 GPM maximum labels cannot stand in for its rated point. 3400 exceeds 3000 and 2.6 exceeds 2.0.

In practice
Differences you will notice
The bigger PSI in the advertising does not mean the higher-rated machine
WPX3400 specifies 3400 PSI at 2.6 GPM. Grandfalls Pro advertises a 3700 PSI maximum, but its rated point is 2700 PSI at 1.2 GPM. An approved attachment that needs at least 3000 PSI and 2 GPM is cleared by Westinghouse's output but not by Giraffe's rated point. Still check the accessory's upper limits and connectors. Neither specification proves that a particular driveway will take fewer minutes.
How we worked this out
Giraffe's separate 3700 PSI and 1.6 GPM maximum labels cannot stand in for its rated point. 3400 exceeds 3000 and 2.6 exceeds 2.0.
The engine has to stay outside, even if the hose reaches indoors
Exhaust can cause fatal carbon monoxide poisoning, so WPX3400's manual prohibits running the engine inside a garage or other building. It requires outdoor placement away from openings. If your planned parking position is indoors, reject that setup. Grandfalls Pro has no engine exhaust source, but it still needs an approved wall, electrical connection, water route and installation environment. Choose it only once those requirements are checked.
How we worked this out
The manufacturer sets this as a safety restriction, and it is not a relative noise or emissions test. Leaving the garage door open does not turn the prohibited engine location into an approved one.
Different layouts call for fixed reach or movable reach
WPX3400 includes 25 feet of hose on a wheeled 63 lb frame, while Grandfalls Pro supplies a 100-foot retractable hose. Giraffe is the pick for repeated washing within a measured fixed route. Westinghouse is the pick when separate outdoor work areas justify moving the washer and its engine can be placed safely each time. Neither hose length guarantees access around a house, since corners, obstacles and required slack reduce usable reach.
How we worked this out
Four times the included hose length is what 100 divided by 25 equals. That difference does not establish pressure at the nozzle once extensions are added, and it does not approve changing either supplied setup.

Spec by spec
Where they really differ
| Spec | Westinghouse WPX3400 Gas Pressure Washer | Giraffe Tools Grandfalls Pressure Washer Pro 100 ft | In practice |
|---|---|---|---|
| Rated operating output | Rated output is 3400 PSI at 2.6 GPM. | Rated output is 2700 PSI at 1.2 GPM. | Giraffe's rated pressure and flow are both exceeded by the gas machine's rated point. |
| Placement | A 212 cc four-stroke gas engine drives an axial-cam pump. | The unit is a fixed wall-mounted pressure washer with a 100-foot retractable hose. | Site constraints differ between a wheeled gas engine and a wall-mounted electric unit. |
| Hose reach | The pressure hose is 25 feet and the frame has 12-inch wheels. | The unit is a fixed wall-mounted pressure washer with a 100-foot retractable hose. | Within one approved area, a longer fixed hose can mean fewer moves. |

Decision guide
How to decide
Pick WPX3400 for a permitted outdoor job that needs its rated 3400 PSI at 2.6 GPM and a movable gas-powered setup. Pick Grandfalls Pro for repeat washing around a fixed 100-foot hose installation that has suitable water and power. The gas engine cannot run inside a garage, and Giraffe's 3700 PSI headline is above its 2700 PSI rated point.
The bigger PSI in the advertising does not mean the higher-rated machine
Grandfalls Pro advertises a 3700 PSI maximum, but its rated point is 2700 PSI at 1.2 GPM. WPX3400 specifies 3400 PSI at 2.6 GPM. Take an approved attachment that needs at least 3000 PSI and 2 GPM. Westinghouse clears those output thresholds, and Giraffe's rated point does not. You should still check the accessory's upper limits and connectors. Neither specification proves that a particular driveway will take fewer minutes. 3400 exceeds 3000 and 2.6 exceeds 2.0. Giraffe's 3700 PSI and 1.6 GPM maximum labels are separate, and they cannot stand in for its rated point.
The engine has to stay outside, even if the hose reaches indoors
The manual for WPX3400 prohibits running the engine inside a garage or any other building, because exhaust can cause fatal carbon monoxide poisoning. It calls for outdoor placement away from openings. If you planned to park it indoors, rule that setup out. Grandfalls Pro has no engine exhaust source, but it still needs an approved wall, electrical connection, water route and installation environment. Choose it only after those requirements have been checked. This is a manufacturer safety restriction and not a relative noise or emissions test. Opening a garage door does not turn the prohibited engine location into an approved one.
Different layouts call for fixed reach or movable reach
Grandfalls Pro comes with a 100-foot retractable hose, whereas WPX3400 includes 25 feet and sits on a wheeled 63 lb frame. Giraffe is the better fit for repeated washing along a measured fixed route. Westinghouse is the better fit when separate outdoor work areas justify moving the washer, as long as its engine can be placed safely every time. Neither hose length guarantees access around a house, since corners, obstacles and required slack cut into usable reach. 100 divided by 25 equals four times the included hose length. The difference does not establish pressure at the nozzle after added extensions, and it does not approve changing either supplied setup.
What this page can’t tell you
