Electric patio washers in the results are generally rated around 1900–2400 PSI, while surface-cleaner attachments shown in listings are rated up to about 4000 PSI.
Listed flow rates include about 1.7–1.8 GPM for several electric washers. One surface-cleaner description lists 2.7 GPM, and a 20" surface cleaner is noted with a 6 GPM max flow.
All results show corded electric power. Common specifications listed are 120 V at 60 Hz, with current ratings such as 11 A or 14 A on different units; one listing also specifies power as 1900 W.
Listed safety features include a total stop system (TSS) that shuts the unit off when the trigger is released, GFCI protection on the power plug, overheat and overload protection, trigger/gun safety locks, and IPX5 water-resistance on some models.
