A dust extractor is a fine-filtered vacuum, often HEPA, built to run with power tools, with tool auto-start and filter cleaning. A shop vac is a general wet/dry cleanup vacuum whose basic filter clogs on fine dust. For tool work, the Dapper 10-gallon dust extractor at $459.95 is our pick, and the Dapper 8-gallon auto HEPA extractor at $300 is the lower-priced way to get automatic filter cleaning. For spills and debris, the Dapper 10-gallon shop vac at $155 does the job.
Quick answer
Buy a dust extractor if you sand drywall, cut or grind concrete or run tools that make fine dust every day. Buy a shop vac if the mess is chips, water and debris. Browse every dust extractor we carry, the wider wet/dry vacuum range or the HEPA vacuums.
The short comparison
Both are a tank, a hose and a motor. The difference is what sits around the motor.
| Feature | Dust extractor | Shop vac |
|---|---|---|
| Built for | Fine dust from sanding, cutting, grinding and drilling | General cleanup of debris, chips and liquids |
| Filter | Fine filter, often HEPA | Basic cartridge or foam filter; Dapper's shop vacs list a wide filter and a cylinder filter |
| Filter cleaning | Automatic or push-button cleaning | Tap, rinse or swap the filter by hand |
| Tool auto-start | Outlet that starts the vacuum when the tool runs | Switch on by hand |
| Liquids | Dapper's do, after swapping to the sponge filter | Standard feature |
| Airflow (Dapper listings) | 140 to 151 CFM | 108 to 206 CFM |
| Suction (Dapper listings) | 18 to 23 kPa | 21 to 25 kPa |
| Water lift | 84.3 in on the 8-gallon auto | 76.3 to 80.4 in |
| Hose | 7.5 ft on the 10-gallon and the semi-auto, 13.1 ft on the 8-gallon auto, all 1-1/4 in where listed | 4.9 to 8.2 ft |
| Noise | 82 dB(A) in Dapper's 10-gallon manual | 78 to 80 dBA listed |
| Continuous running | 20 minutes then rest, per Dapper's 10-gallon manual | |
| Warranty | 2 years listed, 1 year in the manual | 1 year |
| Price in our range | $300 to $459.95 | $155 to $390 |
What they share
Both types are wet/dry tank vacuums with a hose and floor tools, and the Dapper cords run 13 to 19.7 ft. Both need the right filter for the material: a dry filter for dust and a sponge filter for water.
What a dust extractor adds
A finer filter
A basic shop vac filter catches chips and coarse debris, but fine powder packs into it or passes through it. The Dapper extractors we carry list HEPA filtration. Dapper's listings give no efficiency figure for the HEPA filter, so check the maker's documentation if a job needs a specific rating. Dapper's manual for the 10-gallon extractor goes further than its listing: it says the machine is certified to M-Class dust collection standards. It still gives no HEPA efficiency figure. See our guides to what a HEPA vacuum is and what a HEPA filter is.
Filter cleaning while you work
A filter loaded with dust chokes airflow, and the vacuum loses suction mid-job. Extractors answer this with a cleaning system. The Dapper 10-gallon extractor cleans its filter automatically every 20 seconds, and the Dapper 8-gallon auto model does the same every 25 seconds. The 8-gallon semi-auto uses push-button HEPA cleaning: you press the button when suction fades. A shop vac has neither. For the hand methods, see our guide on how to clean a vacuum filter.
Tool auto-start
All three Dapper extractors have a tool-activated outlet rated up to 5.5 A. Plug a sander or another small tool into the vacuum, and the vacuum starts when the tool does and stops after it. That keeps dust from escaping before you reach a switch. The outlet is rated up to 5.5 A, and many corded grinders and saws draw more. Check the tool's nameplate, and plug anything bigger into the wall with the vacuum in manual mode.
Wet pickup too
Dust extractors are not dry-only. Dapper lists the 8-gallon extractor for wet, dry and dust use. Dapper's manual says to remove the dust bag and the dry filters before wet use and fit the sponge filter instead, so going from drywall dust to water means a filter change. If you plan to use any vacuum for liquid, follow our steps for using a shop vac for water, including the filter setup.
Do not assume it is quieter
Dapper's 10-gallon manual lists 82 dB(A) while its shop vacs list 78 to 80 dBA. Neither figure states the measuring distance.
Spec table: the machines we carry
Figures are the listed ratings. Airflow is in CFM and suction in kPa, so compare like with like only.
| Machine | Type | Tank | Airflow | Suction | Filter | Filter cleaning | Tool auto-start | Price |
|---|---|---|---|---|---|---|---|---|
| Dapper 8-gallon auto dust extractor | Dust extractor | 8 gal | Up to 140 CFM | 20 kPa | HEPA | Automatic, every 25 seconds | Up to 5.5 A | $300 |
| Dapper 8-gallon semi-auto dust extractor | Dust extractor | 8 gal | Up to 140 CFM | 18 kPa | HEPA | Push-button, semi-automatic | Up to 5.5 A | $345 |
| Dapper 10-gallon dust extractor | Dust extractor | 10 gal | 151 CFM | 23 kPa | HEPA | Automatic, every 20 seconds | Up to 5.5 A | $459.95 |
| Dapper 21-gallon shop vac | Shop vac | 21 gal | 206 CFM | 25 kPa | Wide carpet filter and cylinder filter | By hand | None listed | $390 |
| Dapper 10-gallon shop vac | Shop vac | 10 gal | 108 CFM | 21 kPa | Wide filter and cylinder filter | By hand | None listed | $155 |
| Tornado Taskforce external filter | Industrial wet/dry | 16 gal | 184 CFM | External filter, 1,268 sq in area | None listed | $1,878 |
On paper the 21-gallon shop vac moves the most air of the six (206 CFM against 140 to 151 CFM for the extractors), while the 10-gallon shop vac lists the least at 108 CFM. Airflow says nothing about how the filter handles fine dust or whether suction holds after an hour of grinding. The extractor's value is in the filter and its cleaning.
One warning on these numbers. Dapper's user manual for the 10-gallon extractor (model DP-DE1136) lists lower figures than its product listing: 19 kPa of vacuum and a maximum airflow of 1.8 cubic meters per minute, about 64 CFM. Makers rarely say how a CFM figure was measured, so use these numbers to rank machines from one maker's listings, not as the airflow you get at the end of the hose.
Peak horsepower, explained
Dapper rates its shop vacs by peak motor power. "Peak" labels a top figure the motor can reach, not a power it holds while working.
Dapper's own listings show the gap. Its 26.5-gallon shop vac lists 11 peak HP (8,100 W peak) and its 21-gallon lists 8.5 peak HP (6,300 W peak), but both list the same 206 CFM and 80.4 inches of water lift. The 10-gallon's 4.0 peak HP sits beside an 1,800 W peak motor, about 2.4 HP at 746 W per horsepower (our calculation), so even the two figures disagree. Read peak HP as a label, not a performance figure.
The extractors list a 1,200 W motor without the word peak. Our calculation: 1,200 W at 120 V is about 10 A, so the vacuum plus a 5.5 A tool is about 15.5 A, and Dapper's manual says the machine shuts down above 15 A. Turn the speed knob down with a larger tool.
Can I use a shop vac as a dust extractor?
Partly. A shop vac with a fine filter, plus a separator ahead of the tank, can handle light dust from occasional sanding. The limits show up fast: no tool auto-start or filter cleaning, and a filter and seal not designed for fine dust, so suction fades and some dust can pass back into the room. For daily tool work, an extractor saves time. For the full plan, our guide to dust control in construction covers sealing, negative air and HEPA vacuuming.
What OSHA's silica table says about tool dust collection
For construction work that makes silica dust, OSHA's standard (29 CFR 1926.1153) has a Table 1 that lists tasks and the controls to use with them. For handheld and stand-mounted drills, Table 1 says that the dust collector "must provide the air flow recommended by the tool manufacturer, or greater" and "have a filter with 99% or greater efficiency and a filter-cleaning mechanism". It also says to "use a HEPA-filtered vacuum when cleaning holes". For handheld grinders, both for mortar removal and for other uses such as surface grinding, the table calls for "25 cubic feet per minute (cfm) or greater of airflow per inch of wheel diameter" and a filter with 99% or greater efficiency and a cyclonic pre-separator or filter-cleaning mechanism.
Our calculation from that figure (25 CFM x wheel diameter in inches): a 4-1/2 inch wheel needs about 113 CFM, a 5-inch wheel 125 CFM and a 7-inch wheel 175 CFM. The Dapper extractors list 140 to 151 CFM, and a listed CFM is more than what reaches a shroud through a hose.
That language asks for airflow set by the tool maker, filter efficiency and a way to clean the filter, the features that separate an extractor from a basic shop vac. It is not a statement that any machine we sell meets the standard. See our guide to HEPA vacuums for asbestos, lead and mold for how the rules treat HEPA vacuums.
Dust extractor vs dust collector
The names get mixed up. A dust extractor is a portable vacuum with a small-diameter hose that connects to a single tool. A dust collector is a stationary system for woodworking machines such as a table saw or planer: it moves a large volume of air at low pressure through wide ducting. Neither replaces the other, and many woodshops end up with both.
Can you vacuum with a dust collector? Only light floor sweepings through a floor port or a short, wide hose. Its high-volume, low-pressure airflow loses pickup through a long, narrow vacuum hose.
The picks, by job
Drywall sanding and small-tool work: Dapper 10-gallon dust extractor
Best for regular tool work
Dapper Supply 10-Gallon Wet/Dry Dust Extractor, 151 CFM, Auto HEPA Filter
$459.95
Automatic filter cleaning and tool auto-start suit sanders and other small tools.
Dapper's listing rates the 10-gallon extractor at 151 CFM and 23 kPa (its manual lists 19 kPa and about 64 CFM), with a 10 gallon tank. It cleans its filter automatically every 20 seconds, which holds suction as the filter loads. Dapper's manual sets a limit: do not run it continuously for more than 20 minutes without a rest. Dapper's manual says to use it indoors only. The hose is 7.5 ft and the cord 13 ft. Dapper's listing shows a 2-year parts and labor warranty, but its manual and own product page say one year from purchase, so confirm the term before you buy.
Pros
- Filter cleans itself every 20 seconds
- Tool auto-start up to 5.5 A
- Dust indicator and overload protection
Cons
- Costs well above a basic 10-gallon shop vac
- 13 ft cord is short without an extension
- Manual limits continuous running to 20 minutes
Skip it if your jobs are wet debris and garage cleanup. You are paying for filter cleaning you will not use.
Lower-priced automatic cleaning: Dapper 8-gallon auto HEPA extractor
Best value extractor
Dapper Supply 8-Gallon Wet/Dry Dust Extractor, Auto HEPA Filter, 1200W
$300
Self-cleaning HEPA filter, tool auto-start and the longest hose of the three.
The 8-gallon auto model lists up to 140 CFM, 20 kPa and 84.3 inches of water lift from a 1,200 W motor. Its HEPA filter cleans itself every 25 seconds, and auto-start supports tools up to 5.5 A. The hose is 13.1 ft of 1-1/4 inch, the longest of the three extractors, with a 19.7 ft cord. It costs less than the semi-auto model.
Pros
- Self-cleaning HEPA filter at the lowest extractor price
- Longest hose and cord of the three extractors
- Rolling base
Cons
- Smaller tank and less suction than the 10-gallon
- Same 5.5 A limit on the auto-start outlet
Skip it if you need the largest tank. The 10-gallon extractor holds more and lists more suction.
Push-button cleaning: Dapper 8-gallon semi-auto dust extractor
Push-button filter cleaning
Dapper Supply 8-Gallon Wet/Dry Dust Extractor, 1200W, Semi-Auto HEPA, Tool Auto-Start
$345
HEPA filtration and tool auto-start with filter cleaning on a button.
The 8-gallon semi-auto lists up to 140 CFM, 18 kPa and a 1,200 W motor. Filter cleaning is semi-automatic: you push a button when suction fades, rather than letting the machine do it on a timer. Tool auto-start works up to 5.5 A. The 7.5 ft hose and 13 ft cord match the 10-gallon model.
Pros
- HEPA filtration and tool auto-start
Cons
- Filter cleaning needs a button press
- Smaller tank and lower suction than the 10-gallon
Skip it if you want hands-off filter cleaning. The Dapper 8-gallon auto HEPA extractor self-cleans every 25 seconds and costs less.
Large debris and water: Dapper 21-gallon shop vac
Best for volume
Dapper Supply 21-Gallon Wet/Dry Vacuum, 8.5 Peak HP, Stainless Steel Tank
$390
Stainless tank, drain port and the highest airflow of the six.
This is the biggest of the Dapper shop vacs we list here: a 21 gallon stainless steel tank, 206 CFM, 25 kPa and 80.4 inches of water lift. It has a built-in drain port and a dual filter (wide carpet filter and cylinder filter) and Dapper lists it as UL certified.
Pros
- Large tank for wet jobs and debris
- Built-in drain port
- UL certified, as listed by Dapper
Cons
- No filter cleaning or tool auto-start
- 1 year warranty
Skip it if the work is fine dust. The wide filter and cylinder filter are not an extractor's filtration.
Garage and general cleanup: Dapper 10-gallon shop vac
Entry-level pick
Dapper Supply 10-Gallon Wet/Dry Vacuum, 4.0 Peak HP, 3-in-1 Stainless Steel Shop Vac
$155
3-in-1 wet, dry and blower in a stainless tank for everyday cleanup.
The 10-gallon shop vac lists 108 CFM, 21 kPa and 76.3 inches of water lift in a stainless steel tank. It works as a wet vac, a dry vac and a blower with a 16.4 ft cord. The hose is 4.9 ft, shorter than the extractors' 7.5 ft.
Pros
- Lower-priced than every other machine here
- 3-in-1: wet, dry and blower
- A 16.4 ft cord
Cons
- Short 4.9 ft hose
- No filter cleaning or tool auto-start
Skip it if you plan to connect it to a sander. A fine-dust load will clog its filter.
Industrial wet/dry with a large filter: Tornado Taskforce external filter
Industrial option
Tornado Taskforce - External Filter Wet/Dry Electric Industrial Vacuum (98995)
$1,878
A 16-gallon bagless vacuum with a large external filter.
The Taskforce is a different design: a 2.25 HP corded motor, a 16 gallon tank, 184 CFM and 51 inches of water lift, with a large external filter of 1,268 square inches. It is bagless and weighs 65 lb. Tornado's brochure lists drywall dust, sawdust, cement dust, water and powder among what it recovers. It says the vacuum picks up wet and dry material without stopping to change or clean an internal filter, and it takes 1.5 and 2-inch hoses. Tornado aims it at maintenance departments and industrial sites. Of the 16 gallon tank, Tornado rates 12 gallons as wet/dry capacity.
Pros
- Large external filter area
- 16 gallon tank in a 65 lb machine
- Commercial build
Cons
- Highest price of the six
- No tool auto-start listed
Skip it if you need to connect to a power tool. The extractors are the tool-driven choice. For other commercial machines, browse our industrial vacuums.
Common mistakes
- Plugging a tool over 5.5 A into the auto-start outlet.
- Picking up water with the HEPA filter and dust bag still fitted.
- Running past the 20-minute continuous limit in Dapper's manual.
- Emptying a fine-dust tank without a bag.
- Using a long, narrow hose on a grinder shroud that needs high airflow.
How to choose by job
| Job | Pick | Why |
|---|---|---|
| Drywall sanding | Dapper 10-gallon extractor | Fine filter, auto-start with the sander and automatic cleaning |
| Concrete grinding or cutting | Dapper 10-gallon extractor, small tools only | Filter cleaning, but a 7-inch wheel needs 175 CFM by our calculation from OSHA's figure, and many grinders draw more than the 5.5 A outlet |
| Occasional drilling or sanding | Dapper 8-gallon auto extractor | HEPA filtration, automatic cleaning and auto-start at the lowest extractor price |
| Workshop with chips and spills | Dapper 10-gallon shop vac | Wet, dry and blower in one machine |
| Large wet cleanup | Dapper 21-gallon shop vac | 21 gallon tank with a drain port |
| Maintenance and industrial cleanup of dust and debris | Tornado Taskforce | Large external filter, 16 gallon tank |
A shop that sands every day should look at the automatic filter cleaning on the 10-gallon or the 8-gallon auto model, check each tool's amps against the 5.5 A outlet and add a dust collector if a planer or jointer is in the room.
Are dust extractors worth it?
Yes, if you make fine dust on a regular schedule. The price gap over a shop vac buys a finer filter, filter cleaning and auto-start. If you make fine dust once a year, a shop vac with a fine filter is enough. The gap between the 10-gallon extractor at $459.95 and the 10-gallon shop vac at $155 is the cost of those features.
Frequently asked questions
Can you use a shop vac as an extractor?
For light, occasional dust, yes, with a fine filter and a separator ahead of the tank. For daily tool work, no. A shop vac has no tool auto-start or filter cleaning, and its basic filter clogs on fine dust.
What is another name for a dust collector?
A dust collector is also called a dust extraction system or dust collection system. In woodworking, it means a stationary unit that pulls a large volume of air through ducting. A portable dust extractor is a vacuum that connects to one tool.
Which dust extractor is best?
In our range, the Dapper 10-gallon extractor at $459.95 has the largest tank and cleans its filter every 20 seconds. The Dapper 8-gallon auto HEPA extractor at $300 also self-cleans, every 25 seconds, with a 13.1 ft hose. The 8-gallon semi-auto suits lighter use. All three list HEPA filtration and tool auto-start up to 5.5 A.
Is it good to have a shop vac?
Yes. A shop vac handles spills, debris, leaves and chips. A 10-gallon model costs about $155. It is the wrong tool for sanding drywall or grinding concrete.
What size shop vac do I need for dust collection?
Match the vacuum's airflow to the tool. For drills, OSHA's silica table asks for the airflow the tool maker recommends, or greater. For grinders, it asks for 25 CFM per inch of wheel diameter. Most product pages in our vacuum range list airflow and tank size.
Do I need HEPA for concrete dust?
Not for the tool's own dust collector under OSHA's Table 1. It asks for a filter of 99% or greater efficiency with a filter-cleaning mechanism, while OSHA defines HEPA as at least 99.97% efficient at 0.3 micrometers. HEPA does come in elsewhere. Table 1 calls for a HEPA-filtered vacuum when cleaning drilled holes, and the standard's housekeeping rule bars dry sweeping where it adds to silica exposure unless wet sweeping, HEPA-filtered vacuuming or other low-dust methods are not feasible.
