Verdict
The DEWALT DXV09P is the best all-around shop vac for most homeowners and DIYers thanks to its balance of capacity, suction, and price; the Craftsman CMXEVBE17040 is the better choice for tight storage and auto-detailing; and the Shop-Vac 4-gallon is the budget pick for occasional light-duty cleanup.

A shop vac is one of those tools nobody thinks about until they're standing in a puddle of water from a failed washing machine hose, or ankle-deep in drywall dust after a demo day. What separates a good one from a frustrating one isn't the peak horsepower number on the box — it's real suction under load, how quickly the filter clogs on fine dust, and whether the hose and cord are long enough that you're not constantly re-plugging the thing. We tested three widely available wet/dry vacs — the DEWALT DXV09P, the Craftsman CMXEVBE17040, and the Shop-Vac 4-gallon — on the same three jobs: vacuuming drywall dust off a workbench, sucking up a simulated water spill, and clearing wood shavings and screws off a garage floor.
What to look for in a shop vac
Peak HP vs. real airflow (CFM). Peak horsepower is a motor spec measured under conditions no shop vac ever actually runs in — it's marketing shorthand, not a performance guarantee. Airflow, measured in CFM (cubic feet per minute), tells you far more about how fast the vac will actually clear debris. The DEWALT DXV09P's rated 90 CFM was noticeably more confident on wood shavings and heavier debris than the two 4-gallon units in our test.
Tank size is a real tradeoff, not just a bigger-is-better spec. A 9-gallon tank means fewer trips to a drain, but it's heavier, bulkier, and harder to store in a closet or a small garage corner. A 4-gallon unit is easier to carry one-handed up a flight of stairs for a quick spill, but you'll be emptying it constantly on an all-day renovation cleanup.
Filter type matters more than people expect. A standard cartridge filter is fine for wet pickup and larger debris, but fine drywall dust will clog it fast unless you also have a dedicated dust bag or foam sleeve rated for fine particulate. All three vacs we tested ship with a washable cartridge filter, but only checking the fine print tells you whether a fine-dust bag is included or sold separately.
Hose length and diameter decide how much you're dragging the whole vac around a room versus just the hose. A 7-foot hose (like the Craftsman's) is noticeably more restrictive than DEWALT's longer setup when you're working around a car or up a ladder.
The rankings
Best overall: DEWALT DXV09P — ~$100–140
The DXV09P is a 9-gallon, 5 peak HP poly-tank vac rated at 90 CFM airflow, and in our testing it was the only one of the three that didn't hesitate on a full pass of wood shavings mixed with screws and washers — it just cleared the floor in one pass without bogging down. Water pickup was equally confident; the float shutoff engaged cleanly once the tank filled, without the sputtering some cheaper units exhibit near capacity. It ships with extension wands, a floor nozzle, a crevice nozzle, a utility nozzle, a washable cartridge filter, and disposable filter bags — a genuinely complete kit for the price.
The catch is size: a 9-gallon poly tank is not a small object, and if your storage space is a closet shelf rather than a garage corner, that's worth weighing against the performance gain.
Best compact / most portable: Craftsman CMXEVBE17040 — ~$100–150
Craftsman's 4-gallon, 5.0 peak HP unit is built for a different job than the DEWALT — quick pickup, easy carrying, and enough tank for auto detailing or a single room's worth of debris rather than an all-day job site. In our testing it handled wet spills and light dust competently, and its smaller footprint made it noticeably easier to carry up stairs or wedge into a car trunk. Its accessory set — a 7-foot hose, car nozzle, utility nozzle, dusting brush, two extension wands, and a cartridge filter — is well suited to detailing work specifically.
Where it falls behind the DEWALT is on heavier debris and larger cleanup jobs: the smaller tank means more trips to empty, and the shorter hose is more limiting when you're working around furniture or a vehicle.
Best budget pick: Shop-Vac 4-Gallon (5430112) — ~$60–80
Shop-Vac's entry-level 4-gallon unit, rated at 4.5 peak HP with a blower function, a 1.25-inch by 6-foot hose, and a 10-foot cord, is the pick for someone who needs a shop vac in the garage for occasional light-duty cleanup and doesn't want to spend $100+ to get one. It handled dust and small spills adequately in our testing, but its shorter, narrower hose and lower airflow showed their limits on the wood-shavings-and-screws test, where debris occasionally needed a second pass.
It's not the vac to buy if you're planning a full renovation cleanup, but for spills, garage floor debris, and the occasional wet/dry emergency, it's a fair value.
Who should buy which
If you're renovating, doing regular workshop cleanup, or just want a vac that won't struggle on anything you throw at it, the DEWALT DXV09P is the smartest buy — it's the rare tool here that's both the best performer and reasonably priced. If storage space is tight or your main use case is quick spills and car detailing, the Craftsman CMXEVBE17040's smaller footprint is worth the tradeoff in capacity. And if you need a shop vac only occasionally and want to spend as little as possible, the Shop-Vac 4-gallon gets the basic job done.
Verdict
Shop vacs are a category where spending a bit more buys real, usable performance rather than marketing fluff — the DEWALT's higher CFM was obvious the moment we ran it against wood shavings and screws, not just on a spec sheet. We're rating this roundup 8.3/10: strong, honest value across all three price points, with the DEWALT DXV09P standing out as the one most homeowners should buy first.
Pros
- DEWALT DXV09P delivers 90 CFM and 9 gallons of capacity for under $150
- Craftsman CMXEVBE17040 is compact and light enough for one-handed carrying between rooms
- All three include a real accessory kit — hose, nozzles, and extension wands — not just the bare tank
Cons
- DEWALT DXV09P is bulkier to store than the two 4-gallon units
- Craftsman's smaller tank means more trips to empty on a big renovation cleanup
- Shop-Vac's lower peak HP and shorter hose show up on heavier debris and standing water
