A 20-inch stainless steel disc that rolls across a full driveway without you fighting the weight.

You get a 20-inch cleaning disc made from heavy-duty stainless steel, which resists rust and handles daily professional use. At 27 pounds, this is the heaviest attachment in the lineup. But the four casters (swiveling wheels) and dual handles make it roll smoothly, so you do not bear all that weight. The fully sealed and pre-greased swivel (the rotating joint) keeps debris out, so you do not need to stop and unclog it mid-job.

Buyers report that after one defective unit was replaced by customer support, the replacement cleaned with a loud, healthy spinning circle and removed grime effectively with slow overlapping passes. The maker claims a no-striping clean from two high-pressure water jets. Owners confirm it leaves no marks when you move at the right pace. It handles a maximum of 4500 PSI (pounds per square inch, water pressure) and 4 GPM (gallons per minute, water flow), making it work with most gas-powered washers above 2000 PSI.

Unlike the lighter RIDGE WASHER model, which goes up to 6.6 GPM, the WOJET tops out at 4 GPM. But for most home washers, that flow is plenty. At 20 inches, it covers roughly 40% more ground per pass than a 14-inch disc, so a two-car driveway wraps up in well under an hour.

A 20-inch disc that skips the streaks without making you drag a heavy steel body.

MEKOH’s 20-inch attachment uses two high-pressure spinning nozzles that the maker says deliver non-marking clean. Reviewers confirm it leaves no irregular stripes when you keep a steady pace. One buyer who upgraded from a smaller Ryobi model called it “two different worlds.” The housing is lightweight PP (polypropylene, a type of plastic) with solid brass fittings. At roughly 17.3 pounds, it is much lighter than the all-steel WOJET 20″.

The maximum flow rate is 4 GPM (gallons per minute, water flow) at 4500 PSI (pounds per square inch, water pressure). The included 3/8-inch quick-connect inlet makes hookup simple on most gas washers. The design has 4 universal casters (swiveling wheels) and two angle-adjustable handles. One reviewer noted that the handle flops when stored and suggested adding a lock — a minor nuisance if you plan to keep it assembled in a garage. It handles water temperatures up to 158°F, so hot-water machines work fine too.

Owners mention it removed 5-year-old algae and old roof repair stains from a sidewalk in one session. The 20-inch disc covers a lot of ground fast, roughly 40% more area per pass than a 14-inch cleaner. That makes it a strong choice for patios and large driveways without the weight penalty of a full stainless build.

The only surface cleaner here that handles a 6.6 GPM (gallons per minute) flow without choking your washer.

Most attachments in this category top out at 3.7 to 4 GPM. The RIDGE WASHER accepts up to 6.6 GPM at 4500 PSI (pounds per square inch, water pressure). That means it is one of the rare picks that will not bottleneck a high-output commercial gas washer. The body is lightweight PP (polypropylene, a type of plastic) with upgraded internal bearings to prevent leaks. It handles water temperatures up to 158°F. Customers note the locking handle lets you walk behind it without squeezing the trigger, a big relief on a 61,000-square-foot driveway.

One buyer mentioned that if you see lines after washing, it is usually user error — proper dwelling time with soap and a mix of lateral and horizontal passes solves it. The dual handles provide two-grip stability. Owners describe the 20-inch disc as “well-made” and “beautiful.” The tip threads are 1/8-inch, which some buyers found difficult to match with aftermarket nozzles in different spray angles.

Compared to the WOJET 20″, which maxes at 4 GPM, the RIDGE WASHER is the better match for machines pushing 5 GPM or more. At roughly 24.7 pounds (11.2 kg), it is lighter than the WOJET’s 27 pounds but heavier than the MEKOH. It still feels substantial underfoot.

A 16-inch all-stainless disc that is big enough for a driveway yet light enough to store on any shelf.

At 16 inches, this WOJET strikes a balance between the small 12-inch RYOBI and the massive 20-inch models. It covers a two-car driveway in under 90 minutes without being too bulky to store. The body is all 304 stainless steel with metal fittings, zero plastic, and a dual-sealed swivel assembly (the rotating joint) that prevents leaks. It weighs 10.73 pounds, while the 20-inch WOJET is listed at 27 pounds. Most homeowners can lift it comfortably onto a storage shelf.

The brush skirt (a ring of bristles around the disc) keeps spray directed downward so water does not mist back at your legs. Reviewers point out it cleans aggregate driveways, wood decks, and brick patios without needing to switch attachments. One owner mentioned that a leak developed after a few years, but customer service replaced the part at no cost — a sign the manufacturer stands behind it. It fits pressure washers rated 2000 to 4500 PSI (pounds per square inch, water pressure) with a standard 1/4-inch quick connect inlet.

Compared to the 19-inch Wexo Palindrog, which weighs 7.9 pounds and handles up to 4000 PSI, the WOJET 16 is heavier but uses fully stainless construction versus the Wexo’s mixed materials. The 16-inch disc is also more maneuverable around landscaping and corners than a 19- or 20-inch disc, making it a better fit for detailed residential work.

A 19-inch disc that gives near-20-inch coverage without the stainless steel price tag.

If you want a large disc but do not need a stainless steel tank, this 19-inch attachment from Wexo Palindrog covers a massive area per pass at a budget-friendly price point. It handles up to 4000 PSI (pounds per square inch, water pressure) with a flow rate between 1.8 and 3.7 GPM (gallons per minute, water flow). That makes it work with most gas washers and larger electric models. The stainless steel construction and durable bearings give it a solid feel. The 4 universal wheels (swiveling casters) glide smoothly across concrete and pavers.

Shoppers say it works well with a 2300 PSI electric washer even though the minimum recommendation is 2500 PSI. So if your machine is slightly underpowered, it still does the job, just at a slower pace. One owner reported it cuts through dirt “like butter” and cleaned half a patio in 30 minutes. The package includes two extension wands, replacement nozzles, O-rings, thread seal tape, and a nozzle cleaner. That adds real value compared to bare-bones attachments.

Compared to the RURRBOOB 14″, which is good for 4500 PSI and 3.7 GPM, the Wexo Palindrog’s 19-inch disc covers about 36% more surface area per pass. That is a meaningful difference when cleaning a full driveway. The trade-off is that a 19-inch disc demands more water flow to spin effectively. Very small electric washers under 1.8 GPM may struggle to rotate the jets properly.

A 14-inch stainless steel disc that slides between patio furniture and curb edges without fuss.

If your cleaning area is more sidewalk and patio than open driveway, a 14-inch disc is easier to control. It is less likely to bump into planters and furniture. This RURRBOOB model uses 304 industrial-grade stainless steel for the housing, heavy-duty bearings, and metal jets. There are no plastic parts in the cleaning path. It handles up to 4500 PSI (pounds per square inch, water pressure) with a flow rate up to 3.7 GPM (gallons per minute, water flow). That means it pairs well with both mid-range gas washers and larger electric models.

Buyers report it works well with a 3500 PSI washer on patios and sidewalks. The 4 universal wheels (swiveling casters) with a 180-degree swivel bearing make it easy to steer one-handed. The kit includes two 15-inch extension wands, four spray nozzle tips, replacement nozzles, O-rings, and a nozzle cleaner. That is a comprehensive package that saves you from buying extra parts. One customer observed that the quick-connect fitting felt loose and had some play when attaching the gun, so check the connection before full-pressure use.

Compared to the RYOBI 12″, which maxes at 3100 PSI and 1.2 GPM, the RURRBOOB’s 14-inch disc offers a 45% higher pressure ceiling (4500 versus 3100 PSI). Its flow rate of 3.7 GPM is a 3.1x gap versus the RYOBI’s 1.2 GPM. That gives it noticeably more cleaning power on tough grime. The trade-off is that it draws more water, so very small electric washers may not supply enough flow.

A 5.29-pound 12-inch disc built for the low flow of small electric washers.

Many surface cleaners demand 2+ GPM (gallons per minute, water flow) that a typical electric pressure washer simply cannot deliver. This RYOBI is designed to work with the lower flow of electric machines. Its maximum flow rate is 1.2 GPM at 3100 PSI (pounds per square inch, water pressure), closely matching what a residential electric washer puts out. At just 5.29 pounds, it is the lightest attachment in the lineup, roughly half the weight of the 10.73-pound WOJET 16″. Carrying it to the backyard is easy.

Owners mention it effectively cleans a wooden deck with a 2000 PSI washer, removing winter dirt in just a few passes. One user highlighted it cleans flat surfaces about 4 times faster than a standard spray nozzle. It works well with the Ryobi 3000 PSI washer. Owners have cleaned entire driveways, sidewalks, and porches in a single afternoon. The caster wheels help it glide, though some found the disc smaller than expected. At 12 inches, it covers less ground per pass than a 14- or 16-inch model.

Compared to the RURRBOOB 14″, which offers 4500 PSI and 3.7 GPM, the RYOBI’s 1.2 GPM flow is a 3.1x gap. The RYOBI is purpose-built for electric washers that simply cannot push 3+ GPM. If your machine is a small electric unit, this RYOBI attachment will spin properly when larger discs would stall out.
