Quick verdict
The WG647 is a 5.3 pound handheld cleaner that delivers 800 PSI and 1.0 GPM from two 20V Power Share batteries, with a 20 foot quick-connect hose, a five-pattern nozzle and two speed settings. It is for bikes, boats, patio furniture, muddy boots and rinsing a car, not for driveways. For those jobs it is quick, portable and simple.

A Cleaner, Not a Pressure Washer
The Worx WG647 belongs to a category Worx helped create: the handheld power cleaner. It delivers 800 PSI and 1.0 GPM from a brushless motor in a 5.3 pound body, powered by two 20V Power Share batteries combined for 40 volts. A 20 foot hose with a filter draws from a tap or a bucket, and a five-in-one nozzle covers 0 to 40 degree patterns plus a watering mode. It is designed for the jobs between a garden hose and a real pressure washer.
This review is based on Worx’s specifications and on owner feedback rather than on our own research.
Cleaning Performance
At 800 PSI the WG647 is several times stronger than a hose nozzle and nowhere near a 2000 PSI washer. Owners use it to rinse cars and boats, blast mud off bikes and boots, clean patio furniture and grills, wash windows and hose down dog runs. For those jobs it is quick and effective. Stained concrete and mossy decks are beyond it, and buyers expecting pressure-washer results on hard surfaces are the main source of disappointment.
Portability
This is the reason to buy it. At 5.3 pounds it carries in one hand, needs no outlet and no tap, and the bucket siphon means it works at a boat ramp, a campsite or the far end of a garden. Owners with boats and RVs are its most enthusiastic users.
Controls and Nozzle
Two speed settings trade pressure for runtime. The five-in-one nozzle twists between patterns, and the watering setting turns the unit into a powered hose for plants. A soap bottle attachment is available separately.
Batteries and Runtime
The WG647 kit ships with two 20V batteries and a charger, and the packs are shared with Worx drills, trimmers and blowers. Runtime is the limit: owners report 15 to 25 minutes of trigger time on a pair of 2.0Ah packs, which covers a car rinse or a bike but not a long session. Larger 4.0Ah packs help.
Build Quality
Fittings are light-duty plastic appropriate to the price. Owners report reasonable durability with indoor storage and care not to run it dry.
Common Owner Complaints
Expectations of pressure-washer performance, short runtime and the occasional leaking hose connection. Within its intended use, satisfaction is high.
Alternatives to Consider
Ryobi’s 40V EZClean is the direct rival with similar output. For real cordless pressure, the EGO HPW3200 is in a different class and price. For cars at home, a compact electric such as the Karcher K1700 Cube offers more for less.
Verdict
Buy the WG647 for what it is: a light, cordless, tap-free cleaner for bikes, boats, gear and quick rinses. It does those jobs well and goes anywhere. Do not buy it to clean a driveway.
