Get Maximum Drain Cleaning Force
PWMA compliant electric pressure washers from Ryobi and Greenworks deliver close to their advertised GPM flows at their rated PSI pressures. Most other brands produce much less flow than advertised.
Sewer jetter cleaning force increases with GPM squared, so Ryobi and Greenworks electric machines' verified 1.2 GPM flows can give you 40-50% more drain cleaning force than other 110 volt pressure washers.
You'll get top performance from this sewer jetter when powered by all 1.2 GPM Ryobi and Greenworks machines, including the economical hand-carry models that cost around $99.
