Head-to-head

Westinghouse WPX3400 vs Giraffe Grandfalls Pro: Movable outdoor gas power or a permanent wall wash station

The short answer

Choose WPX3400 for a permitted outdoor job needing its rated 3400 PSI at 2.6 GPM and a movable gas-powered setup. Choose Grandfalls Pro for 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 is above its 2700 PSI rated point.

Before you choose

The reasoning and the trade-offs

The higher advertising PSI is not 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. For an approved attachment needing at least 3000 PSI and 2 GPM, Westinghouse clears those output thresholds while Giraffe's rated point does not. Still check the accessory's upper limits and connectors. Neither specification proves a particular driveway will take fewer minutes.

What this is based on

3400 exceeds 3000 and 2.6 exceeds 2.0. Giraffe's separate 3700 PSI and 1.6 GPM maximum labels cannot be substituted for its rated point.

About this comparison

Compare Westinghouse WPX3400 and Giraffe Grandfalls Pro for rated pressure-flow, gas-engine placement, fixed hose reach and water supply.

Winner by situation

Start with what you need it to do

  • My approved attachment needs 3000 PSI and 2 GPM

    WPX3400 clears the output thresholds, subject to remaining compatibility limits. Giraffe's rated point does not.

  • I intend to run the machine inside a garage

    The gas engine is explicitly prohibited indoors. Giraffe still requires an approved installation environment.

What matters in practice

The differences that matter

The higher advertising PSI is not 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. For an approved attachment needing at least 3000 PSI and 2 GPM, Westinghouse clears those output thresholds while Giraffe's rated point does not. Still check the accessory's upper limits and connectors. Neither specification proves a particular driveway will take fewer minutes.

How we reached this conclusion

3400 exceeds 3000 and 2.6 exceeds 2.0. Giraffe's separate 3700 PSI and 1.6 GPM maximum labels cannot be substituted for its rated point.

The engine must remain outside even when the hose reaches indoors

WPX3400's manual prohibits operating the engine inside a garage or other building because exhaust can cause fatal carbon monoxide poisoning. It requires outdoor placement away from openings. If your planned parking position is indoors, reject that setup. Grandfalls Pro avoids an engine exhaust source, but still needs an approved wall, electrical connection, water route and installation environment. Choose it only after those requirements are checked.

How we reached this conclusion

This is a manufacturer safety restriction, not a relative noise or emissions test. An open garage door does not convert the prohibited engine location into an approved one.

Fixed reach and movable reach solve different layouts

Grandfalls Pro supplies a 100-foot retractable hose, while WPX3400 includes 25 feet and uses a wheeled 63 lb frame. Prefer Giraffe for repeated washing within a measured fixed route. Prefer Westinghouse 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, because corners, obstacles and required slack reduce usable reach.

How we reached this conclusion

100 divided by 25 equals four times the included hose length. The difference does not establish pressure at the nozzle after added extensions or approve changing either supplied setup.
