Who is the Greenworks Patio Cleaner for?
The Greenworks Patio Cleaner is designed for homeowners who already own a Greenworks electric or battery-powered pressure washer. It is best suited for cleaning flat, paved surfaces such as patios, driveways, sidewalks, and decking. If you are looking to upgrade from a standard spray nozzle to a surface cleaner that provides more even results and less splashback, this attachment is a logical step.
It is less ideal for professionals or those with gas-powered pressure washers from other brands, as the connection and flow rate may not match. Owners of Karcher, Nilfisk, or Bosch machines should check compatibility before purchasing.
Performance and Cleaning Power
The Greenworks Patio Cleaner relies on the pressure and flow from your existing pressure washer. According to the manufacturer, it is rated for use with pressure washers up to 3200 PSI and a flow rate of up to 2.0 GPM. The 15-inch cleaning head covers a larger area than standard 12-inch models, which can cut cleaning time by roughly 20-30% on larger patios.
Aggregated owner reviews on major retail sites indicate that the cleaner performs well on concrete and brick pavers, removing dirt, mildew, and light algae without leaving streaks. The dual high-pressure jets rotate inside the housing, creating a consistent cleaning pattern. Some users note that on heavily stained surfaces, a pre-treatment with a detergent is still necessary.
Build Quality and Durability
The housing of the Greenworks Patio Cleaner is made from heavy-duty plastic, which keeps the weight down to around 5 pounds. This makes it easy to maneuver, but several long-term owners have reported that the plastic housing can crack if dropped on hard concrete. The included anti-splash skirt is made from a durable rubber material that helps contain spray and reduce mess.
The internal brass fittings and stainless steel jets are more robust, but the overall construction feels less premium than metal-bodied competitors from Karcher or DeWalt. The warranty is a standard 2-year limited warranty, which is average for this category.
Ease of Use and Setup
Assembly is straightforward and requires no tools. The handle snaps into place, and the quick-connect fitting attaches to most Greenworks pressure wands. Users report that the unit is easy to push across flat surfaces, and the swivel joint prevents the hose from tangling. The cleaner is designed to be used at low speed, allowing the rotating jets to do the work without forcing the machine.
One common complaint in owner reviews is that the cleaner can be difficult to maneuver on uneven surfaces like cobblestones or textured paving. The rigid plastic base does not conform to bumps, which can cause the cleaner to skip or leave uncleaned patches.
Alternatives to the Greenworks Patio Cleaner
If you do not own a Greenworks pressure washer, or if you prefer a more durable build, consider these alternatives. The Karcher T5 Surface Cleaner offers a metal housing and is compatible with most Karcher K-series machines. The Ryobi 15-inch Surface Cleaner is a direct competitor with similar specs and a slightly higher build quality. For a universal option, the Simpson Cleaning 60130 MegaShot works with most gas and electric pressure washers.
