RYOBI is one of the best-known names in home outdoor power equipment, and its pressure washers are a common first purchase for new homeowners who want to clean a driveway, a deck or a sidewalk without hiring someone. The brand’s gas models use small engines to push water at high pressure, and it also sells electric models and attachments that work with those machines.
The four listings below are not four of the same thing: two are gas pressure washers at 2900 and 3300 PSI, one is a 15-inch surface cleaner attachment (sold used), and one is a 2500 PSI electric pressure washer.
RYOBI Gas Pressure Washers Compared
| Model | Type | Max pressure | Flow rate | Hose length |
|---|---|---|---|---|
| 2900 PSI Gas Pressure Washer (RY802925VNM) | Gas pressure washer | 2900 PSI | 2.5 GPM | 25 ft |
| 3300 PSI 2.5 GPM Cold (RY803325) | Gas pressure washer | 3300 PSI | 2.4 or 2.5 GPM (listing conflicts) | 50 ft |
| 15 in. 3400 PSI Gas Surface Cleaner (RY31SC15) | Attachment, used | Rated up to 3400 PSI | Not listed | Not listed |
| 2500 PSI 1.2 GPM Electric (RY142500) | Electric pressure washer | 2500 PSI | 1.2 GPM | 25 ft |
PSI, GPM and Gas vs Electric Explained
PSI stands for pounds per square inch and measures how hard the water hits the surface. More PSI helps lift stuck-on grime from concrete and brick. GPM stands for gallons per minute and measures how much water flows through; more GPM rinses dirt away faster and covers more area. A good rule of thumb for first-time buyers is that both numbers matter, so a machine with slightly lower PSI but higher GPM can finish a big driveway sooner than one with high PSI and a trickle of water.
In the gas vs electric pressure washer debate, gas models run anywhere without a cord and usually offer more flow, but they need fuel, oil changes and more storage space. Electric models start with a switch, are quieter and need less maintenance, but they must stay near an outlet. If you want neither gas nor a cord, our guide to the RYOBI battery power washer covers that third option.
RYOBI 2900 PSI Gas Pressure Washer for Everyday Home Cleaning
Ryobi
RYOBI 2900 PSI Gas Pressure Washer & 25 FT Hose, GREEN
Price and specifications are read from the Amazon product page and can change.
RYOBI 2900 PSI Gas Pressure Washer
Best for: Homeowners with siding, bricks and big driveways
Pros
- 2900 PSI at 2.5 GPM
- 212cc engine
- Four quick-connect nozzles
- 12-inch flat-free wheels
Cons
- Shorter 25 ft hose
- Weight not listed
The RYOBI 2900 PSI Gas Pressure Washer (model RY802925VNM) uses a 212cc horizontal engine to deliver 2900 PSI and 2.5 GPM. That combination handles the jobs the description lists: siding, bricks, sidewalks and large driveways. The listing mentions a large-capacity fuel tank for longer runtime but does not give its size.
It comes with four quick-connect nozzles, which snap on and off the wand: 0 degree for a narrow, powerful jet on tough spots, 25 degree for general cleaning, 40 degree for a gentler fan on delicate surfaces, and a soap nozzle for applying detergent. There is on-board storage for them, a sturdy metal wand, a 25-foot non-marring hose that will not leave marks on your deck, and a hand-truck frame with 12-inch flat-free wheels. It measures 18 x 18 x 28 inches and meets EPA standards.
This ryobi 2900 psi gas pressure washer suits a first-time homeowner with a typical house and driveway. It gives way to the 3300 PSI model if you want a longer hose and more pressure for stubborn stains.
RYOBI 3300 PSI 2.5 GPM Cold for Tougher Jobs
Ryobi
RYOBI 3300 PSI 2.5 GPM COLD WATER GAS PRESSURE WASHER GREEN #RY803325
Price and specifications are read from the Amazon product page and can change.
RYOBI 3300 PSI 2.5 GPM COLD
Best for: Tough driveway and deck jobs
Pros
- 3300 PSI, most pressure here
- 50 ft hose
- Folding handle, roll-cage frame
- 5-in-1 quick-connect nozzle
Cons
- Engine and GPM details conflict
- Fuel tank size inconsistent
The RYOBI 3300 PSI 2.5 GPM COLD water gas pressure washer (ryobi 3300 psi ry803325) is the most powerful true pressure washer here at 3300 PSI. “Cold water” simply means it uses water straight from your garden hose rather than heating it. It includes a 50-foot hose, twice the length of the 2900 PSI model, plus a 5-in-1 quick-connect nozzle that switches spray patterns by turning rather than swapping tips. It has a compact roll-cage frame and a folding handle for storage, and weighs 37 pounds.
This listing contains several contradictions you should know about. The features say a 212cc horizontal engine, while the description names a 201 cc premium engine from another manufacturer. Flow is given as 2.4 GPM in one place and 2.5 GPM in another. The fuel tank is listed as 0.95 gallon in the features but 2.5 gallons under tank volume. The features also claim three times longer runtime than standard models without explaining the comparison. The description mentions idle down technology but is cut off before explaining it.
It suits homeowners with long driveways, oil-stained concrete or a large deck, especially if the extra hose length saves moving the machine. Confirm the engine and tank details with the seller before buying.
RYOBI 15 in. 3400 PSI Gas Surface Cleaner as an Add-On
Ryobi
RYOBI 15 in. 3400 PSI Gas Pressure Washer Surface Cleaner with Caster Wheels, Yellow, RY31SC15
Price and specifications are read from the Amazon product page and can change.
RYOBI 15 in. 3400 PSI Gas
Best for: Existing owners cleaning large flat surfaces
Pros
- 15-inch cleaning path
- Rated for up to 3400 PSI
- Caster wheels
Cons
- Listed as used
- Attachment only, 30-day warranty
The RYOBI 15 in. 3400 PSI Gas surface cleaner (ryobi 3400 psi surface cleaner ry31sc15) is not a pressure washer on its own. It is an attachment: a round, 15-inch hood with a spinning spray bar inside that you connect to a gas pressure washer and roll across flat ground. It cleans driveways and patios evenly without the stripes a wand can leave. The 3400 PSI figure is the maximum pressure it is rated to handle, not pressure it produces.
Important for buyers: the listing clearly says this unit is “Used,” and it carries a 30-day limited warranty. It weighs 6.5 pounds and measures 14 x 10 x 3.5 inches as listed, which seems small for a 15-inch cleaning path, so the numbers may refer to a part or packaging. The listing gives no connection type or flow requirement. It has caster wheels for rolling.
This suits someone who already owns a gas pressure washer and has a big concrete area. First-time buyers should get a pressure washer first. For more add-ons, see our roundup of RYOBI pressure washer attachments.
RYOBI 2500 PSI 1.2 GPM High Performance Electric for Small Spaces
Ryobi
RYOBI 2500 PSI 1.2 GPM High Performance Cold Water Electric Pressure Washer
Price and specifications are read from the Amazon product page and can change.
RYOBI 2500 PSI 1.2 GPM High
Best for: Patios, fences and small driveways
Pros
- No gas or oil to manage
- Brushless motor
- Turbo nozzle included
Cons
- Only 1.2 GPM flow
- Needs an outlet nearby
The RYOBI 2500 PSI 1.2 GPM High Performance model is an electric pressure washer, included for shoppers weighing a ryobi 2500 psi electric pressure washer against gas. It delivers 2500 PSI at 1.2 GPM using a brushless motor, which the description says maximizes efficiency and extends the life of the machine.
A turbo nozzle is included, which the listing says gets the job done 50% faster than a standard nozzle. It has a metal wand, a quick-connect nozzle coupler and a 25-foot hose, weighs 40 pounds and meets EPA standards. The listing also shows a 1-gallon tank volume without explaining what the tank is for. The description names patio furniture, fences, decks, siding, sidewalks and small driveways as good jobs for it.
This suits homeowners with smaller spaces who do not want to store gasoline. Its 1.2 GPM is about half the flow of the gas models, so large driveways will take longer; for those, the 2900 PSI gas model is the better tool.
How to Choose the Right RYOBI Pressure Washer
Match the machine to your biggest job. For patio furniture, fences and a small driveway, the 2500 PSI electric model is enough. For siding, bricks and large driveways, choose a gas model: 2900 PSI for most homes, 3300 PSI for heavier stains or larger areas.
Look at GPM as well as PSI. The ryobi pressure washer gpm figures here run from 1.2 on the electric model to about 2.5 on the gas models. More flow means faster rinsing on large surfaces.
Think about hose length and storage. The 3300 PSI model’s 50-foot hose lets you reach more of the yard without moving the machine, and its folding handle helps in a crowded garage. The 2900 PSI model has large wheels for rolling across grass.
Add accessories later. The surface cleaner makes driveways much faster, but it is used, needs a gas machine, and has only a 30-day warranty. For sweeping walkways, a RYOBI pressure washer water broom is another handy extra.
