Three vacuums matched to the cleanup job
BAUER/HFT 6-gallon wet/dry vacuum & blower
Nicholas owns this 4 peak HP corded vacuum. It is the general-purpose shop-vac option in this comparison. Confirm the BAUER/HFT listing and hose/accessory package before ordering.

Milwaukee 0880-20 M18 cordless wet/dry vacuum
Nicholas uses this for smaller cleanup jobs when it is not worth dragging out a larger shop vacuum. Check whether the listing includes a battery and charger; this portable unit does not replace a larger-capacity vac.

DEWALT DXV12P 12-gallon wet/dry vac
A 12-gallon, 5.5 peak HP option for readers who need more tank capacity for heavier garage cleanup. We have not personally tested this model; compare filtration, hose and storage needs before buying.

Shop vac sizing in 30 seconds
Cars & quick cleanup
Prioritize: portability, compact storage and useful detailing attachments.
A smaller tank is easier to carry and is usually enough when the debris volume is low.
General garage
Prioritize: balanced capacity, reach and maneuverability.
A mid-size wheeled wet/dry vac is often the most versatile one-machine solution.
Wood chips & bulky debris
Prioritize: hose diameter, capacity and easy emptying.
Larger debris is where a restrictive hose and small tank become annoying quickly.
Renovation & fine dust
Prioritize: appropriate filtration and dust-management features.
For demanding fine-dust control, consider whether a purpose-built dust extractor better matches the job.
Tank size is about workflow
A larger tank means fewer stops to empty debris or liquid, not automatically stronger suction. A compact vacuum can be easier to carry into a vehicle, onto a workbench or around the house. Large 12- to 16-gallon machines are better suited to bigger cleanup jobs where capacity and long cords matter more than portability.
Look past peak horsepower
Peak horsepower is widely used on consumer wet/dry vacuums, but it is not operational horsepower. DEWALT notes that the rating includes laboratory motor-output conditions and that motors do not operate at that peak in actual use. When comparable data are available, airflow in CFM and suction or water-lift specifications provide additional useful context.
Hose diameter changes what fits
A smaller hose is easier to maneuver and works well for dust, vehicle interiors and tight spaces. A larger hose is less likely to clog on wood chips and bulky debris. Before buying, think about what you actually vacuum most often and whether your preferred nozzles, dust separators or power-tool adapters fit the hose system.
Filtration matters
Fine dust is a different job from picking up screws or water. Match the filter and bag to the debris and follow the vacuum manufacturer's wet-pickup instructions before collecting liquid. For serious dust control, a purpose-built dust extractor can offer features such as automatic filter cleaning, tool activation and specified HEPA filtration that a basic cleanup vacuum may not.
Cordless or corded?
Cordless wins for fast cleanup and mobility, especially if you already own batteries in the same platform. Corded machines avoid battery-runtime limits and are usually the better fit for long sessions. Battery and charger inclusion also matters to real purchase price because many cordless vacuums are sold as bare tools.
Features worth paying attention to
Look beyond headline capacity. A drain can make liquid cleanup easier on larger tanks. Onboard hose and accessory storage reduces the odds of losing attachments. Cord length and hose reach determine how often you move the machine. Noise matters in an attached garage. If you intend to connect the vacuum to power tools, verify hose and adapter compatibility before buying.
Three real models to compare by job
These are research-based examples that illustrate different buying paths. We have not tested them side by side. The links go to manufacturers, not affiliate checkout pages; confirm the exact model and current specifications before ordering.
General garage: RIDGID RT1200 NXT
RIDGID lists a 12-gallon drum, 15-foot cord, 2½-inch accessory size, built-in drain and 144 CFM air-volume specification. It is a concrete starting point for comparing a full-size wheeled vac against smaller machines.
Check before buying: the 12-gallon footprint and 2½-inch accessory system may be cumbersome for tight car interiors; compare the included hose and detailing accessories.
Large cleanup: DEWALT DXV16P-QTA
DEWALT lists this Stealthsonic model as a 16-gallon wet/dry vacuum with a 6.5 peak-HP label. Consider it if larger debris or liquid loads and reduced noise are priorities.
Check before buying: confirm its loaded size, hose and filter setup; peak HP is not a measure of operating suction.
Tool-connected dust: Festool CT 26 EI HEPA
Festool describes tool-triggered operation and wet/dry extraction for the CT 26 EI HEPA. Its stated maximum volume flow is 138 CFM. The workflow and filtration system, rather than tank gallons alone, are the reason to compare it.
Check before buying: hose adapters, bags, filters and the exact dust-control requirements of your work. This is a different purchase category from general floor cleanup.
CFM figures above come from each maker’s own specifications. They are not necessarily measured under identical conditions and should not be treated as a head-to-head suction ranking.
Our practical sizing rule
Buy the smallest machine that comfortably handles your normal mess, not the largest tank that fits your budget. For detailing and quick cleanup, portability is king. For a general garage, a mid-size wheeled wet/dry vacuum balances storage, reach and capacity. For renovation debris and large liquid pickup, move up in tank size and prioritize a drain, sturdy wheels and a hose that will not choke on debris.

The shop-vac buying shortlist
These are use-case recommendations based on the buying criteria above, not hands-on product tests. Check the current manufacturer specifications and the exact model before ordering.
Compact detailer
For car interiors and small cleanup, compare carry weight, hose reach, crevice tools and storage. A modest tank is fine when you empty it after each job.
Watch out: Small hoses can clog on larger debris.
Mid-size garage wet/dry vac
For a one-machine garage setup, prioritize maneuverability, replacement filters, cord and hose reach, and a tank you can empty comfortably.
Watch out: A larger tank adds bulk without improving suction by itself.
Dust-focused extractor
For frequent tool-connected fine dust, compare specified filtration, bag availability, hose adapter fit and automatic tool start where useful.
Watch out: Check job-specific dust rules and filtration requirements before relying on a general-purpose vacuum.
