The Milwaukee M18 shop vac to choose for extra tank space is the M18FPOVCL. The 0880-20 makes more sense for repair work where you want the hose and small tools packed inside a toolbox-style vacuum.
Both suit short wet and dry cleanup jobs away from an outlet. Your best choice depends on what you collect, how often you move and which compatible batteries you already have.
Which Milwaukee M18 shop vac fits your work?
Choose the M18FPOVCL for extra collection space or the 0880-20 for organized transport. Neither is the right size for routinely clearing large piles or collecting water across a broad area.
Think about your last few cleanup jobs before comparing features. Crumbs under a car seat, debris beside a repair and a small household spill favor portability; a floor covered in renovation debris favors a larger tank.
A cordless vacuum is especially useful when getting out an extension cord would take longer than the cleanup. For a fixed workshop station, a corded model can spare you the need to share batteries with other tools.
Our complete shop vac buyer's guide explains the broader choices if you're still deciding between a portable vacuum and a full-size machine.
What makes the M18FPOVCL worth choosing?
The M18FPOVCL offers more tank space and higher water lift than the 0880-20, making it the better fit when those are your priorities. Its 2.5-gallon capacity, 50 CFM airflow and 47 in. water lift give you clear comparison points.
Milwaukee M18FPOVCL 2.5-Gallon Cordless Wet/Dry Vac: Best for room-to-room cleanup
- 2.5-gallon capacity
- 50 CFM
- 47 in. water lift
- HEPA filter
Choose this Milwaukee for moving between small wet and dry jobs when extra tank space matters. Two speeds let you adjust the power setting to the task.
Pros
- Larger tank than the 0880-20
- Higher water lift than the 0880-20
- HEPA filter
- Two speeds
Cons
- Small tank for bulk cleanup
- Battery charge planning needed
Airflow describes the volume of air moving through the vacuum. Water lift describes suction against resistance, so consider both when judging a vacuum for loose debris, narrow tools or wet pickup.
This model also has 2 speeds. Start with the lower setting for light debris, then increase power if the material needs it rather than leaving the vacuum at its highest setting by habit.
Its HEPA filter is useful for fine-particle filtration, but the filter label doesn't make every dust suitable for collection. Follow Milwaukee's material restrictions and don't assume a portable shop vac is approved for hazardous dust.
Who should buy this Milwaukee M18 shop vac?
Buy the M18FPOVCL if you move between small cleanup areas and want extra room before emptying. It fits a routine that includes household debris, garage touch-ups and occasional wet pickup.
Skip it if your main work fills a small tank repeatedly. The extra half gallon over the 0880-20 helps, but it doesn't turn this portable model into a bulk-cleanup machine.
For car use, confirm that your chosen package has the hose and attachments you need. Tank size won't solve a reach problem beneath seats or behind a center console.
When is the Milwaukee 0880-20 the better choice?
The 0880-20 is the better choice for carrying a complete cleanup kit between small jobs. Its toolbox design and onboard hose and accessory storage keep loose parts together.
Milwaukee 0880-20 M18 2-Gallon Wet/Dry Vac: Best for mobile repair work
- 2-gallon capacity
- 6 ft hose
- Onboard hose and accessory storage
- Built-in blower port
A toolbox-style vacuum for repair jobs where keeping the hose and attachments together saves packing time. It works with Milwaukee 18V slide-on batteries, including Li-ion and NiCd.
Pros
- Onboard hose and accessory storage
- Includes crevice tool and utility nozzle
- Built-in blower port
- Reusable wet/dry filter
Cons
- Small tank for repeated liquid pickup
- Lower maximum suction figure than the M18FPOVCL
It has a 2-gallon tank, 6 ft hose and built-in blower port. The included crevice tool handles narrow areas, while the utility nozzle gives you a wider opening for general debris.
Those parts suit repair work where you alternate between open floor space and tight corners. Packing the attachments back into the vacuum also reduces the chance of leaving a nozzle behind at the last job.
The 0880-20 works with Milwaukee 18V slide-on batteries, including Li-ion and NiCd. That broad compatibility is useful if you already have suitable packs, but confirm the exact fit before buying another battery.
Its maximum suction is 32 in., below the M18FPOVCL's water-lift figure. Choose it for its carrying and storage layout rather than expecting it to lead this pair on suction.
Skip this model if you mainly need repeated liquid collection or bulk debris removal. Its included tools make small jobs convenient, but the tank still sets the emptying schedule.
Use the blower port only where moving debris away serves a purpose. Blowing fine dust around an enclosed garage creates another cleanup job; collecting it is usually the better approach.
Should DeWalt battery owners choose the DCV580H?
The DeWalt DCV580H makes sense if you already own compatible 20V MAX batteries and want a portable wet/dry vacuum. Staying with an existing battery platform can simplify charging and storage.
DeWalt DCV580H 20V MAX Cordless Shop Vac: Best for DeWalt battery owners
- 2-gallon capacity
- 5 ft hose
- Washable, reusable HEPA-rated filter
- Battery and charger sold separately
A practical alternative for buyers who already have compatible DeWalt batteries. Its washable filter and onboard storage suit recurring small cleanup jobs.
Pros
- Washable, reusable HEPA-rated filter
- Onboard hose and accessory storage
- Includes wide nozzle and crevice tool
Cons
- Small tank for bulk debris
- Battery and charger sold separately
It has a 2-gallon tank and a 5 ft, 1-1/4 in. hose that DeWalt describes as crush-resistant. A wide nozzle, crevice tool and onboard storage cover the basic needs of small cleanup jobs.
The washable, reusable HEPA-rated filter is accessible for maintenance. Clean it as directed and let it dry fully before returning to dry pickup.
The battery and charger are sold separately. Buyers starting without compatible packs should account for the complete setup rather than comparing vacuum bodies alone.
Skip this alternative if keeping everything on your Milwaukee battery system is a priority. It also won't solve the small-tank limits shared by these portable models.

How much tank space and battery capacity do you need?
Choose tank size around how often you're willing to stop and empty, then plan battery use around the length of each cleanup. A larger battery doesn't create more collection space, and a larger tank doesn't extend runtime.
For a few footwells or debris from a small repair, portable capacity can be enough. Repeated trips to a drain or trash bin are a sign that a larger vacuum would better fit the work.
Nominal tank capacity isn't a promise of usable liquid volume. Follow the model's liquid limit and shutoff instructions, and stop promptly if the vacuum signals that it's full.
Don't plan a job around one universal runtime figure. Battery size, power setting, filter condition and the work itself affect how long a cordless vacuum can run.
A spare compatible pack is useful when cleanup follows battery-powered drilling or cutting. Otherwise, the vacuum may need the same nearly empty battery as the tool that made the mess.
Use our shop vac size guide to decide whether portability is worth more to you than fewer emptying stops.
Is an M18 shop vac a good choice for car interiors?
An M18 shop vac suits quick interior cleanup without an extension cord, especially when you can park the vacuum close to each door. Hose reach and nozzle shape matter more here than gaining a little tank volume.
Remove floor mats and large loose items first. Vacuum seats before the floor so debris knocked down from seams gets collected during the final pass.
Use a crevice tool beside seat rails and in narrow gaps, but move it slowly. Rushing over the surface leaves debris trapped between the carpet fibers.
Brush stubborn grit loose before vacuuming it up. Don't press the nozzle so tightly against upholstery that you block airflow, and avoid scraping hard tool edges across delicate trim.
The 0880-20's included tools and storage make it a straightforward option for this routine. For the M18FPOVCL, confirm accessory compatibility before choosing attachments for narrow gaps.

How should you set up a cordless wet/dry vac?
Start with the correct filter arrangement, a clean tank and a secure hose connection. Remove the battery before opening the vacuum or changing internal parts.
For dry pickup, check that the filter is seated correctly and free from tears. Close the tank securely, attach the right nozzle and clear any tight hose bends before switching on.
Use the wide nozzle on open areas and the crevice tool where a broad opening won't fit. Pick up oversized scraps by hand rather than forcing them into a narrow hose.
For wet pickup, follow the exact model's filter instructions. Don't assume every wet/dry vacuum needs its filter removed, or that every filter can remain installed for liquid collection.
Keep the battery and controls away from splashes, and use a stable position that lets you watch the machine. Never use these vacuums for hot ash, fuel or flammable liquids.
For a step-by-step overview, see how to use a shop vac. The model's manual should guide any steps specific to its filter, shutoff or approved materials.
What care prevents weak pickup and unpleasant smells?
Keep the filter, hose and tank clear, and dry the vacuum after wet work. A fresh battery won't correct a blocked air path.
If pickup drops, switch off and remove the battery before checking the nozzle and hose. Then inspect the filter and tank rather than repeatedly increasing the power setting.
Empty dry debris before it crowds the filter or packs tightly into the tank. After wet pickup, empty the collected liquid promptly and clean residue from the tank.
Don't add dry dust to a wet, dirty tank if you can avoid it. The mixture can form sludge that takes longer to remove and can leave odors behind.
The 0880-20 and DCV580H have reusable filters that support washing as directed. Don't assume the same cleaning method applies to the M18FPOVCL's filter; follow its care instructions.
Let washable parts dry fully before reassembly for dry use. Store the hose without sharp kinks and return small tools to their holders so the vacuum is ready for the next job.
Which buying mistakes should you avoid?
Avoid choosing by one suction number, the brand name or a battery you haven't checked for compatibility. Buy the setup that fits your usual task, including the tools needed to reach the debris.
Don't confuse a HEPA filter with approval for hazardous-dust work. Fine construction dust may need a specific collection system, suitable bags or other controls beyond a filter choice.
Don't assume a short hose will reach across a whole vehicle interior. Plan to move the vacuum between doors instead of stretching the hose or pulling the machine by it.
Noise also matters in enclosed rooms and garages. The M18FPOVCL has an 87 dB noise figure, so consider who will be nearby and follow the manual's hearing-protection guidance.
Finally, avoid buying a compact vacuum for a job that routinely overwhelms its tank. Cordless convenience is most useful when the cleanup stays small enough to finish without constant stops.
Which Milwaukee M18 shop vac should you buy?
Choose your Milwaukee M18 shop vac by the job you repeat most often. The M18FPOVCL fits buyers who want extra collection space and higher water lift, while the 0880-20 fits mobile repair work with frequent packing and carrying.
Choose the DCV580H if compatible DeWalt batteries are already part of your routine. Choose a larger corded vacuum if bulk debris or repeated liquid collection matters more than moving without a cord.
Before ordering, settle the battery fit, required attachments and where you'll empty the tank. Our guide to choosing a battery-powered shop vac helps you turn those needs into a complete setup.
