Choosing an industrial vacuum for metal shavings means looking past tank size and wet/dry claims. Metal chips can be sharp, heavy, and mixed with fine dust or cutting fluid, so I focus on tank construction, collection capacity, airflow, filtration, hose reach, and how clearly the product information supports workshop use. These three are general-purpose wet/dry vacuums, not purpose-built metalworking chip collectors, so I would match them to the job rather than assume every one is suitable for every kind of metal debris.

The Dapper Supply 26.5-Gallon is my capacity-led pick, with a stainless steel tank, high listed airflow, and a drain for liquid cleanup. The KARHDIR 16-Gallon is the more accessory-rich choice, pairing a dust separator with HEPA and foam filters, while the Hoteche 20-Gallon puts its emphasis on HEPA filtration. The main tradeoff is straightforward: larger capacity can mean more cumbersome storage and handling, while finer filtration does not by itself establish that a vacuum is rated for hazardous or combustible metal dust.

More Details on Our Top Picks
Dapper Supply 26.5-Gallon Wet/Dry Shop Vacuum
I rank the Dapper Supply first for buyers who want a large metal-tank wet/dry vacuum and need to collect more than a small amount of ordinary shop debris between emptying sessions. Its 26.5-gallon stainless steel tank is the largest listed here, and the built-in drain gives it a practical advantage when cleanup includes liquid as well as dry material. That combination makes it the broadest fit in this group for general workshop maintenance, rather than a specialist answer for every kind of metalworking waste.
The published 206 CFM airflow and 26 kPa suction figures are also the strongest airflow and suction claims among these three listings. I would read those numbers as a useful specification comparison, not a guarantee that it will collect every chip from a machine or handle fine metal dust safely. The dual filtration system is less specific than Hoteche’s stated HEPA rating or KARHDIR’s named HEPA and foam filters, so buyers with fine-dust requirements should investigate filter details before relying on it.
Reach is a point in its favor: an 8.2-foot hose and 13.2-foot cord provide more working room than Hoteche’s listed 1.5-meter hose and 2.3-meter cord. The downside is the same large capacity that makes it appealing: a 26.5-gallon unit can take up substantial storage space and may be less convenient to move around tight work areas. I would choose it over KARHDIR when tank capacity and the liquid drain matter more than a dust separator; I would choose Hoteche instead when a clearly specified HEPA filtration claim is the main priority.
This is my lead pick for high-volume, general wet/dry cleanup, with an important boundary: the supplied information does not identify it as a combustible-metal or hazardous-dust collector. If the debris is a safety-sensitive metal powder rather than ordinary chips and shop dirt, I would not infer suitability from its stainless tank or filtration description.
Pros:- Largest listed capacity here: 26.5-gallon stainless steel tank
- Built-in drain helps empty collected liquids
- High listed airflow and suction compared with the other two options
- 8.2-foot hose, 13.2-foot cord, and multiple attachments
Cons:- Large tank may be awkward to store or maneuver in a crowded shop
- Dual filtration is not described with a specific filter class in the supplied details
- The provided information does not establish suitability for combustible metal dust
Best for: Workshops that want a large stainless steel tank, a liquid drain, and useful hose and cord reach for general mixed wet/dry cleanup.
Not ideal for: Buyers needing a compact vacuum, clearly specified HEPA filtration, or a vacuum certified for combustible metal dust or specialized machine-tool collection.
- Tank capacity:26.5 gallons
- Tank material:Stainless steel
- Airflow:206 CFM
- Suction power:26 kPa
- Water lift:80.4 inches
- Filtration:Dual filtration system
- Hose and cord:8.2 ft hose; 13.2 ft power cord
- Wet/dry use:Yes; built-in liquid drain
Our verdict“I would choose Dapper Supply for the largest general-purpose wet/dry capacity and drain, while verifying filtration and metal-dust suitability for the exact cleanup task.”
KARHDIR 16-Gallon Industrial Wet/Dry Shop Vacuum, 2400W
KARHDIR earns its place through a more layered collection setup than the other two. Its dust separator, two reusable dust bags, and HEPA and foam filters give buyers several included pieces to work with, while the blower function adds another cleanup mode. For a shop that moves between general debris, dry dust, and liquid spills, this package is more versatile on paper than Hoteche’s simpler five-accessory listing.
Its 16-gallon stainless steel tank is smaller than Dapper Supply’s 26.5 gallons and Hoteche’s 20 gallons, so I would expect more frequent emptying during bulk cleanup. That smaller tank can be a reasonable trade if storage or maneuvering matters, though the listed weight of 31.7 pounds still makes it a substantial unit rather than a compact portable vacuum. The 19.7-foot cord is the longest listed here, which can reduce outlet changes in a larger work area; the 8.2-foot hose matches Dapper Supply’s listed hose length.
The published 125 CFM airflow and 19 kPa suction sit below Dapper Supply’s listed 206 CFM and 26 kPa, but above Hoteche’s 60 CFM airflow and 16.5 kPa vacuum pressure. Those measurements make KARHDIR a middle-ground specification choice in this trio, not proof of how it will perform with a particular chip shape or machine. Its filters and separator are appealing features, yet the listing does not say that the product is approved for combustible metal dust or hazardous industrial collection.
I would pick KARHDIR over Dapper Supply when the included separator and accessories are more useful than maximum tank size, and over Hoteche when the longer cord and blower function matter. I would skip it if a lightweight unit is the priority or if the job calls for a verified, metal-specific collection system. Its accessory mix broadens general cleanup, but it does not replace checking the intended use and safety requirements for the material being collected.
Pros:- Includes a dust separator, HEPA and foam filters, and reusable dust bags
- Blower function and multiple brushes support varied general cleanup
- 19.7-foot power cord offers the longest listed reach
- Stainless steel tank handles wet and dry cleanup
Cons:- 16-gallon capacity is smaller than both competitors
- Listed weight of 31.7 pounds may make frequent repositioning less convenient
- Supplied details do not confirm a combustible-metal-dust rating
Best for: Buyers who want a wet/dry vacuum with a dust separator, HEPA and foam filters, a blower function, and a long power cord.
Not ideal for: Shops that need the largest possible tank, a particularly light unit, or documented approval for combustible metal dust collection.
- Tank capacity:16 gallons
- Tank material:Stainless steel
- Motor power:2400W, two motors
- Suction power:19 kPa
- Airflow:125 CFM
- Filters:HEPA and foam
- Hose and cord:8.2 ft hose; 19.7 ft power cord
- Weight:31.7 pounds
Our verdict“I would choose KARHDIR for its separator-and-filter accessory package and long cord, accepting less tank capacity than either competing model.”
Hoteche 20-Gallon Wet/Dry Vacuum Cleaner with Metal Tank
Hoteche is the filtration-led pick in this comparison. Its listing specifies a HEPA filter rated to capture 99.97% of particles as small as 0.3 microns, giving buyers a clearer filter claim than Dapper Supply’s unspecified dual filtration system. That detail can matter when a cleanup includes fine dust along with larger debris, but I would not treat a HEPA specification as a certification for combustible metal dust or as evidence that this general-purpose vacuum suits every industrial process.
The 20-gallon steel tank sits between Dapper Supply’s larger 26.5-gallon vessel and KARHDIR’s 16-gallon tank. That middle capacity may suit a workshop that wants fewer interruptions than a smaller unit without choosing the largest model in this group. Hoteche’s listed 60 CFM airflow and 16.5 kPa vacuum pressure are lower than the figures supplied for the other two products, making it the least compelling choice here if airflow specifications are the deciding factor for bulkier debris.
Its practical limitations are reach and power access. The listed hose is 1.5 meters and the power cord is 2.3 meters, both shorter than the reach figures for Dapper Supply and KARHDIR. In a fixed work bay near an outlet, that may be manageable; across a spread-out shop, it can mean moving the vacuum or using an appropriate, workplace-compliant power arrangement. Hoteche includes five accessories and large wheels, and it handles both wet and dry cleanup, but it does not list a built-in drain like Dapper Supply or the separator and blower features offered with KARHDIR.
I would choose Hoteche when its stated HEPA filtration and mid-size tank best fit the job. I would favor Dapper Supply for more listed airflow, a larger tank, and liquid draining, or KARHDIR for a longer cord and separator. Hoteche is a practical general-purpose option, but the short listed reach and lower airflow figures make it less suited to a large, spread-out shop where frequent movement or high-volume pickup is expected.
Pros:- HEPA filtration is specified at 99.97% for particles as small as 0.3 microns
- 20-gallon steel tank offers a middle capacity between the other two models
- Handles wet and dry cleanup and includes five accessories
- Large wheels support movement around a work area
Cons:- Listed airflow of 60 CFM is lower than the other two options
- 1.5-meter hose and 2.3-meter cord limit working reach
- No built-in drain, dust separator, or blower function is listed
Best for: Workshop buyers who value a stated HEPA filtration efficiency and want a steel wet/dry vacuum with a mid-size tank.
Not ideal for: Users who need long hose and cord reach, the highest listed airflow, a liquid drain, or a documented metal-specific dust collection system.
- Tank capacity:20 gallons / 75 liters
- Tank material:Steel
- Motor power:1200W
- Vacuum pressure:16.5 kPa
- Airflow:60 CFM
- Filter:HEPA; stated 99.97% efficiency for particles as small as 0.3 microns
- Hose and cord:1.5 m hose; 2.3 m power cord
- Noise level:78 dB
Our verdict“I would choose Hoteche when its explicit HEPA specification matters more than reach, airflow, or the extra collection features of its competitors.”
How We Picked
I ranked these options around the demands implied by metal shavings, not around general household cleanup. I compared tank material and capacity because a metal tank and room for collected debris can make shop cleanup more practical. I also looked at airflow and suction figures where supplied, since they offer useful points of comparison, while treating manufacturer specifications as claims rather than proof of performance on a particular machine tool or chip type.
Filtration and collection accessories received close attention. The Hoteche lists a HEPA filter and a stated particle-capture efficiency; KARHDIR includes HEPA and foam filters alongside a dust separator; Dapper Supply describes a dual filtration system but does not identify the filter classes in the supplied details. Those differences matter when dust is part of the mess, but a HEPA label alone does not show that a vacuum is designed for combustible metal dust, fine hazardous powders, or continuous industrial chip collection.
I also weighed practical handling: hose and cord length, tank size, drain access, included accessories, and weight when available. That is why Dapper Supply leads for large-capacity mixed cleanup, KARHDIR takes the accessory-focused role, and Hoteche is the filtration-led option. I have not treated customer feedback as performance evidence or claimed these products are purpose-built chip collectors. For any shop with combustible metals, regulated dust, or machine-integrated collection needs, I would verify the manufacturer’s intended application and workplace safety requirements before buying.
| industrial vacuum for metal shaving | Tank material |

| KARHDIR 16-Gallon Industrial W | Stainless steel |
| Hoteche 20-Gallon Wet/Dry Vacu | Steel |
Factors to Consider When Choosing Industrial Vacuum For Metal Shavings
I would start by defining the material and cleanup task, then compare capacity, filtration, and reach. A wet/dry label covers broad cleanup functions; it does not, by itself, establish safe collection of every kind of metal debris.Identify the metal debris before choosing
Metal shavings can mean large, relatively heavy chips, fine grinding dust, or a mixture that includes oils and cutting fluids. Those materials create different collection needs. A shop vacuum with a metal tank may suit ordinary floor cleanup, but it should not automatically be used to collect combustible metal dust or process waste that requires a dedicated collection system. I would identify the metal, particle form, and workplace rules before comparing the three models.
If the cleanup is connected directly to a machine tool, check whether the manufacturer specifies suitable chip collection, separation, and filtration for that application. None of the supplied product details establishes that these vacuums are certified for combustible-metal service or hazardous dust. When that classification matters, product-specific confirmation takes priority over a general wet/dry claim.
Balance tank capacity against handling
Tank capacity affects how often the unit needs emptying, but a larger tank also occupies more space and can be harder to move when full. Dapper Supply leads this group at 26.5 gallons; Hoteche lists 20 gallons; KARHDIR lists 16 gallons. I would not choose capacity in isolation: consider how much debris the task produces, where the vacuum will be stored, and whether staff can maneuver it around benches or equipment.
For liquid cleanup, the Dapper Supply’s built-in drain is a useful distinction. The other listings describe wet/dry operation but do not specify a tank drain. If collected material includes liquid, check how the tank is meant to be emptied and whether the process fits your shop’s handling practices.
Read filtration claims in context
Hoteche gives the clearest numerical filtration claim, specifying HEPA performance at 99.97% for particles as small as 0.3 microns. KARHDIR lists HEPA and foam filters plus a dust separator, while Dapper Supply describes dual filtration without naming filter classes in the supplied information. These details can help compare general fine-dust handling, but filter labels do not establish suitability for combustible metal dust or a regulated industrial process.
I would also check whether replacement filters and bags are available for the intended duty, how the manufacturer directs users to clean or replace them, and whether dust can escape during emptying. Fine dust can become airborne during disposal even when a filter is fitted. Follow the manufacturer’s instructions and workplace requirements rather than treating filtration claims as a complete safety plan.
Compare airflow, suction, and reach
The listings provide several different measurements, which are useful for a basic comparison but should not be treated as identical tests. Dapper Supply states 206 CFM airflow and 26 kPa suction; KARHDIR lists 125 CFM and 19 kPa; Hoteche lists 60 CFM and 16.5 kPa pressure. I would use these figures as published specifications, not as a promise of pickup performance with a particular hose, attachment, chip shape, or filter condition.
Reach can matter just as much in a working shop. Dapper Supply lists an 8.2-foot hose and 13.2-foot cord, while KARHDIR has an 8.2-foot hose and 19.7-foot cord. Hoteche’s listed hose and cord are shorter at 1.5 meters and 2.3 meters. Measure the distance to the work area and outlet before selecting a model; a long cord does not replace safe power practices or an appropriate outlet.
Match accessories to the actual workflow
Accessories can reduce setup changes, but only when they fit the job. KARHDIR’s separator, reusable dust bags, brushes, and blower function make it the most accessory-focused option. Hoteche includes five cleaning accessories, while Dapper Supply lists multiple attachments and emphasizes its drain and large tank. I would compare the supplied tools with the surfaces and debris you need to collect, rather than assuming more accessories automatically mean better metal-chip pickup.
For machine-area cleanup, check whether the hose and nozzle can reach confined spaces and whether the vacuum is approved for the debris involved. A blower function may move loose material but can also spread dust, so it is not a substitute for controlled collection where airborne particles are a concern. Choose the simplest setup that meets the task and applicable safety requirements.
Frequently Asked Questions
Can these wet/dry vacuums collect metal shavings?
They are presented as wet/dry vacuums for general debris, and their metal or stainless steel tanks make them candidates for ordinary workshop cleanup. The supplied specifications do not confirm that any model is designed or certified for all metal shavings, combustible metal dust, or machine-integrated collection. I would verify the exact material and intended use with the manufacturer before collecting fine, reactive, or safety-sensitive metal waste.
Which of these models has the largest tank?
Dapper Supply has the largest listed tank at 26.5 gallons, followed by Hoteche at 20 gallons and KARHDIR at 16 gallons. The larger Dapper Supply tank may mean fewer emptying stops during general cleanup, but it can also be less convenient to store or maneuver. Tank size does not indicate whether a vacuum is suitable for a particular metal dust hazard.
Which vacuum has the most clearly specified filtration?
Hoteche states a HEPA filtration efficiency of 99.97% for particles as small as 0.3 microns. KARHDIR lists HEPA and foam filters and includes a dust separator; Dapper Supply describes dual filtration without identifying filter classes in the supplied details. These differences help compare the listed filtration information, but none should be read as proof of combustible-metal or hazardous-dust approval.
Is a stainless steel tank enough for metalworking cleanup?
No. A stainless steel tank describes the container material, not the vacuum’s approval for every metal, dust, or industrial collection task. The collection method, filters, electrical design, debris characteristics, and workplace rules may all matter. I would check the manufacturer’s intended application and relevant shop safety requirements before using any general-purpose vacuum on combustible or hazardous material.
Which model is easiest to use across a larger shop area?
KARHDIR lists the longest power cord at 19.7 feet and has an 8.2-foot hose, while Dapper Supply also lists an 8.2-foot hose and a 13.2-foot cord. Hoteche lists a 1.5-meter hose and a 2.3-meter cord, so it may need repositioning more often in a spread-out work area. Actual convenience depends on outlet placement, layout, and safe power arrangements.
Conclusion
For large-volume general wet/dry cleanup, I would start with Dapper Supply: its 26.5-gallon stainless steel tank, drain, and strongest listed airflow make it the capacity-first choice here, with storage bulk and unspecified filter classes as the tradeoffs. For a shop that values a separator, HEPA and foam filters, blower function, and long cord reach, KARHDIR offers the richest listed accessory package, though its tank is the smallest and the unit is not lightweight.
I would choose Hoteche for its explicit HEPA filtration specification and middle-size tank when shorter reach and lower listed airflow fit the workspace. Before buying any of these for metalworking, I would confirm that the exact chips, dust, and fluids are within the manufacturer’s approved use. If the job involves combustible metal dust, hazardous particles, or production-machine collection, these general wet/dry specifications are not enough to establish a safe match.
