Generators and pressure washers compared on the spec sheet, not the box headline.

Running watts, runtime at 25% and 50% load, noise, transfer-switch outlets, CO shutoff, PSI, GPM and pump type. GenPick reads each maker's spec page and ranks inverter, dual-fuel and home standby generators and electric and gas pressure washers with the weights printed on every page. 5 categories, 112 products, 44 head-to-heads.

How it works

1. The maker's spec table

Every figure comes from the manufacturer's own product or spec page, linked on the product card. Jasion and Apollo publish only peak motor watts, and several makers skip weight or water ratings, so those cells stay blank and score as the weakest published value.

2. Different jobs, different weights

Inverters are weighted toward running watts, runtime and noise; open-frame and standby generators toward output, transfer-switch readiness and fuel options; washers toward PSI, GPM and computed cleaning units.

3. Match it to your body

A camping inverter and a whole-house standby kit solve different problems. Size to your running loads, never run a generator indoors, use the guides, then check the price on Amazon. Commissions never change the order.
