Worx WG605 13 Amp Electric Pressure Washer: Rated Versus Maximum Output

  • Small corded washer, 13.8 pounds, with a 13 amp motor and a 20 foot hose.
  • Rated at 1800 PSI and 1.2 GPM, with maximums of 1980 PSI and 1.4 GPM.
  • Stored attributes mix the two figure sets and misfile flow as tank volume.

Description

Who the Worx WG605 is for

The WG605 is a small corded electric pressure washer built around a 13 amp motor on a metal framed base with rubber feet, a carry handle, integrated cord wrap and onboard nozzle storage. At a listed 13.8 pounds it is closer to a portable appliance than to the wheeled machines that dominate this category, and that shapes who it suits. It is for a buyer with a balcony, a small yard, a car and some outdoor furniture, who wants something they can carry out, use for twenty minutes and put away on a shelf.

The decision it settles is whether the smallest practical class of corded washer is enough for your work. If your list is a car, bicycles, garden tools, muddy camping gear, a small patio and some window frames, it is. If your list starts with a driveway, it is not, and the reason is flow rate rather than pressure.

Rated output versus maximum output, published properly

This listing does something most in this catalog do not: it publishes both the rated figures and the peak figures, and it labels them. The bullets state 1800 PSI and 1.2 gallons per minute as the working figures, with maximums of 1980 PSI and 1.4 gallons per minute. The description repeats this, giving 1980 PSI maximum and 1.2 GPM with a 1.4 GPM maximum.

That distinction is the single most useful thing on the page, and it is worth understanding because most competing listings hide it. A maximum PSI figure is typically measured with the trigger closed or under conditions you do not reproduce while cleaning. The rated figure is closer to what arrives at the surface. When you compare this machine against one that advertises only a large maximum number, you are not comparing like with like.

Where the stored attributes disagree

Our stored product attributes record a maximum pressure of 1800 PSI and a maximum flow rate of 1.4 gallons per minute. That combines the rated pressure figure with the maximum flow figure, so neither pair matches the listing cleanly. The attributes also record a tank volume of 1.4 gallons, which is almost certainly the flow figure repeated into the wrong field, since a 13.8 pound machine does not carry 1.4 gallons of detergent. The power source is recorded as AC/DC on a machine the listing describes as corded electric. Treat the bullets and description as the better source and the attribute block as unreliable here.

Setting it up and using it correctly

The 13 amp draw is published, which is more than most listings in this class manage, and it tells you what you need to know about the circuit. A 13 amp appliance is a substantial load on a 15 amp household circuit, so do not share the circuit with another heavy appliance while it is running. The listing does not state whether a GFCI outlet is required or whether the plug carries a GFCI device, which is a gap. Treat a ground fault protected outlet as the requirement regardless, because this is a wet appliance used outdoors. Extension cords are the usual restriction on corded washers, and where a manufacturer permits them at all it will specify a gauge and a maximum length. Check the manual before reaching for the cord you have in the garage. The supplied hose is 20 feet and the wand is 11.6 inches.

Even at 1800 PSI this is not a garden hose. The stream can drive water and grit through skin and produce an injection injury that looks like a small puncture while causing serious damage underneath. Do not aim the wand at a person or an animal, do not steady a workpiece with your free hand near the spray path, and wear eye protection every time, because grit rebounds off hard surfaces.

Three nozzles are supplied: a turbo tip, a 40 degree tip and a soap tip, connected by a universal quarter inch quick connect. The 40 degree tip should be your default. The turbo tip rotates a concentrated stream and will strip paint, raise the grain on softwood decking, and mark vehicle panels if held close. Test on an inconspicuous area, keep the tip moving and hold your distance. An onboard soap tank and soap nozzle let you apply detergent into the stream, which does more of the work on a dirty car than pressure alone.

Limits and gaps

The honest limit is flow. At 1.2 gallons per minute rated, this machine will clean a driveway but slowly, because flow determines how much area each pass clears. It is well matched to vertical and small surfaces and poorly matched to large horizontal ones. Accessory compatibility is the second limit. A quarter inch quick connect is common, but surface cleaners and undercarriage bars sized for M22 fittings will need an adapter, and larger surface cleaners will not get enough water from this machine to spin properly in any case.

Two things are not published. There is no GFCI statement, as noted, and there is no pump type or service information. The metal framed base and rubber feet are described, but the frame does not include wheels, so on a long session you will be lifting rather than rolling. The stored attributes carry a CSA specification met marking and a country of origin of China.

The water side is worth a note too, since the listing does not address it. A pump must be supplied with at least as much water as it moves, and a small machine is no exception. A kinked hose, a narrow bore hose or a tap that is not fully open will starve the pump, and running a pressure washer dry or short of water is the fastest way to damage it. Connect the hose, open the tap fully and let water run through the unit before you pull the trigger the first time. Clean the inlet filter screen occasionally, because grit collecting there produces the same starvation as a closed tap.

Alternatives worth comparing

If portability is the point, the Worx WG644 Hydroshot, which is battery powered and can draw from a bucket takes the idea further and gives up more pressure. The Ryobi RY120350 power cleaner is a comparable small unit. If you want a conventional wheeled machine instead, the Craftsman CMEPW1700 and the Craftsman CMEPW1900 sit just above this class, and the Westinghouse WPX2300e with a 35 foot cord is the full size step up. Our index of corded and cordless machines lists the published figures for each.

Who should buy it and who should not

Buy it if you want a carry sized corded washer for a car, furniture, tools and small paved areas, and you value a listing that publishes its rated figures honestly alongside its maximums. Do not buy it for driveways, long fence runs or large siding jobs, where 1.2 gallons per minute will make the work take much longer than it needs to, and do not assume the stored attribute figures on this page are correct, since they mix the rated and maximum values.
