Ryobi vs Sun-Joe Shop Vac
Choosing between a Ryobi and a Sun Joe shop vac means weighing battery ecosystem convenience against raw corded suction power. We break down the key differences in performance, build, and value to help you pick the right wet/dry vacuum for your garage or workshop.
Quick answer
For most users, the Ryobi 3-Gallon Cordless wins for portability and battery convenience if you are already in the Ryobi ONE+ system. The Sun Joe 5-Gallon Corded is the better choice for raw suction power and continuous runtime at a lower price, making it the best budget pick for heavy-duty wet pickups.

Power and Suction: Cordless vs Corded
The most significant difference between these two shop vacs is the power source. The Ryobi 3-Gallon Cordless runs on an 18V ONE+ battery, offering a peak of 0.9 horsepower. This is adequate for sawdust, drywall dust, and small liquid spills. Owner reviews on Amazon and Home Depot consistently note that suction is good for a cordless vac but drops noticeably as the battery drains.
The Sun Joe 5-Gallon Corded model plugs into a standard wall outlet and delivers a much stronger 1.5 peak horsepower. This translates to significantly higher static water lift and airflow. For tasks like cleaning out a clogged sink trap, sucking standing water from a basement floor, or vacuuming heavier debris like gravel and wood chips, the Sun Joe has a clear advantage. Aggregated reviews highlight its strong, consistent suction that does not fade.
Capacity and Portability
Ryobi wins on portability. At just 7.5 pounds empty and with no cord to manage, you can easily carry it up a ladder, into a car, or around a job site. The 3-gallon dry tank is compact enough to store on a shelf. The trade-off is smaller wet capacity (1.5 gallons) and a smaller filter area, which means you need to empty it more often during big jobs.
Sun Joe offers a larger 5-gallon dry and 3.5-gallon wet capacity. This is better for larger workshop cleanups or garage projects. It is heavier at 11.2 pounds and requires a nearby outlet or an extension cord. Many owners appreciate the built-in blower port, which allows you to use the exhaust air to blow leaves or dust from tight corners, adding versatility that the Ryobi lacks.
Build Quality and Filter System
Both units are built to a budget-friendly price point. The Ryobi features a durable plastic tank and a basic foam filter for wet pickups, plus a paper cartridge filter for dry use. Owners report that the filter can clog quickly with fine dust and requires frequent cleaning. The hose is standard 1-1/4 inch, which is compatible with most shop vac accessories.
The Sun Joe uses a similar dual-filter system (foam sleeve and paper cartridge). The larger tank allows for a slightly larger filter area, which can extend time between cleanings. The casters on the Sun Joe are a bit more robust, and the overall build feels sturdier for the price. However, some Amazon reviews mention the hose can be stiff in cold weather.
Battery Ecosystem vs. Plug-and-Play
If you already own Ryobi ONE+ tools (drills, saws, blowers), the Ryobi shop vac is a no-brainer. You can share batteries and chargers, and the tool-only price is very reasonable. The convenience of grabbing a charged battery and cleaning up a spill without dragging out a cord is a major plus for many DIYers.
Sun Joe is a standalone corded tool. There is no battery system to worry about. You simply plug it in and it works for as long as you need. This makes it a better choice for someone who does not own Ryobi tools or who wants the maximum suction and runtime without worrying about battery management.
What to Check Before Buying
- Your existing battery platform: If you are already invested in Ryobi ONE+, the cordless vac is a smart addition. If not, you will need to buy a battery and charger, which increases the total cost.
- Typical debris type: For fine drywall dust and sawdust, a cordless vac is fine. For wet concrete slurry, gravel, or large volumes of water, the corded Sun Joe is much more capable.
- Noise level: Corded shop vacs are generally louder than cordless models. Owner reviews for the Sun Joe note it is moderately loud, while the Ryobi is quieter, which is a perk for indoor use.
- Filter maintenance: Both models require regular filter cleaning. Consider buying extra filter sets if you do a lot of fine dust work.
Mistakes to Avoid
- Using a paper filter for wet pickup: Always use the foam sleeve for liquids. A soaked paper filter will disintegrate and ruin the motor.
- Overfilling the tank: Stop when the liquid reaches the float shut-off. Continuing to vacuum will blow water out of the exhaust.
- Forgetting to check the hose diameter: Both use 1-1/4 inch hoses, but if you plan to connect to a larger tool, you may need an adapter.
