I need a powerful vacuum to clean out my car and workshop. What's the best wet dry vacuum for around $100?

For around $100 , you can get an absolute powerhouse of a wet/dry vac that will easily chew through heavy workshop sawdust, metal shavings, and ground-in car dirt. At this price point, you want something in the 5 to 6-gallon range —large enough to handle serious debris, but compact and portable enough to haul out to the driveway for your car.

The top options that hit the sweet spot of power, reliability, and price include:

RIDGID 6 Gal. 3.5 Peak HP NXT Shop Vacuum Go to product viewer dialog for this item. ( Home Depot )

• Price: ~$79.98
• Why it’s great: RIDGID is the gold standard for durability and suction in shop vacs. The 3.5 peak HP NXT model gives you incredible suction for its size, features a locking hose that won't pop off mid-clean, and converts easily into a leaf/debris blower. If you want to stretch right up to your $100 budget, you can find bundles that include specialized car-cleaning nozzle attachments.

RIDGID 6 Gal. 4.25 Peak HP Stainless Steel Wet/Dry Vac Go to product viewer dialog for this item. ( Home Depot )

• Price: ~$89.00
• Why it’s great: If you bump slightly up in motor strength (4.25 peak HP) and want a rugged container that won't crack if it gets smashed against a workbench or a car door, this stainless steel version is immensely durable. It handles heavy workshop messes effortlessly.

Shop-Vac 6 Gallon 3.5 Peak HP Utility Vacuum Go to product viewer dialog for this item. ( Acme Tools )

• Price: ~$74.99 - $99.99
• Why it’s great: A classic workhorse that offers balanced airflow, decent capacity, and reliable wet/dry pickup. It comes with a solid assortment of extension wands and nozzle attachments right out of the box.

CRAFTSMAN 5-Gallon 4-HP Corded Wet/Dry Vac Go to product viewer dialog for this item. ( Lowe's )

• Price: ~$69.98
• Why it’s great: Highly portable with a balanced footprint and great everyday suction. It is lightweight, rolls easily on swiveling casters, and leaves you with enough cash left over from a $100 budget to buy extra fine-dust filter bags or a specialized automotive detailing accessory kit.

If you'd like, let me know:

• Do you prefer a plastic drum or a stainless steel build?
• Do you need an included car detailing kit (like micro-hoses or claw nozzles) right away?

I can help you pick the exact model and accessories to match your setup.

For around $100, I’d prioritize a corded 5–12 gallon shop vac with a 2.5-inch hose. That gives you enough airflow for workshop debris while still being practical for car interiors.

My top picks

• RIDGID 4 Gal. 5.0 Peak HP Portable Shop Vacuum - $99.00 (Home Depot)
• DEWALT 6 Gal. 4.0 HP Poly Wet/Dry Vacuum - $76.80 (The Home Depot)
• DEWALT Stealthsonic Quiet 6-Gallon Wet/Dry Vacuum - $84.98 (Lowe's)
• Shop-Vac 16-Gallon 6.5-HP Wet/Dry Vacuum - $99.00 (Lowe's)
• WORKSHOP 9-Gallon 4.25 HP Wet/Dry Vacuum - $89.99 (Tractor Supply Company)

🥇 Best for your mix: RIDGID 4-gallon 5 HP — about $99. It comes with a car-cleaning kit, fine-dust filter, locking hose and accessories, making it particularly well suited to bouncing between a car and workshop.

💪 Best if workshop power matters most: Shop-Vac 16-gallon 6.5 HP — about $99. For big piles of sawdust, wood chips, leaves, etc., the larger tank is a major advantage. It's much less convenient to carry around a car, though.

🔇 Best quieter option: DEWALT Stealthsonic 6-gallon — about $85. Good compromise between portability and workshop capability, and the quieter motor is nice when you're using it for longer periods.

🚗 Best compact car + garage option: DEWALT 6-gallon — about $77. Portable enough to maneuver around a vehicle but still substantially more capable than a dedicated car vacuum.

One important point: don't buy based solely on “peak HP.” Airflow, hose diameter, filtration and the actual pickup performance matter more. Recent testing found the Stanley 6-gallon surprisingly capable, while larger models such as the Craftsman 16-gallon excelled at moving heavy debris.

My pick for you: the RIDGID 4-gallon if the car is the priority; the 16-gallon Shop-Vac if the workshop is the priority. If you want one machine to do both, I'd lean RIDGID for the better balance of portability and serious suction.

For around $100 , you can get an absolute workhorse that handles heavy workshop sawdust, drywall chunks, and muddy car carpets with ease. Around this price point, you want a balance of strong peak horsepower, a decent tank size that isn't too massive to lug around, and solid included car-cleaning attachments.

The top wet/dry vacuums hitting that sweet spot include:

• • Price: ~$89 - $99
  • Why it’s great: This is widely considered the best overall value for a dual garage/workshop setup. It hits the sweet spot of capacity (9 gallons means fewer empties, but it still rolls easily) and features a robust 4.25 peak HP motor that provides serious suction. It also comes packaged with useful automotive attachments (including a car nozzle) and an extra-large built-in drain port for emptying liquids.
• • Price: ~$79 - $90
  • Why it’s great: If you prioritize portability and build quality over a massive drum, RIDGID is legendary for durability. The 3.5 peak HP NXT model is relatively compact, lightweight, features great ergonomic carry handles, and boasts a powerful blower port that's handy for clearing out your garage floor or blowing leaves out of the car before you vacuum.
• • Price: ~$75 - $85
  • Why it’s great: A stellar budget option that punches well above its weight class. It features a strong motor, smooth-rolling casters, and easily converts into a blower. It’s slightly more compact than the Craftsman 9-gallon, making it very maneuverable inside a tighter car interior or a crowded workshop corner.

Recommendation Checklist:

Add to list Go with the Craftsman 9-Gallon Go to product viewer dialog for this item. if you want the strongest motor and capacity combo right at your $100 limit.

Add to list Go with the RIDGID 6-Gallon Go to product viewer dialog for this item. if you prefer a smaller footprint, easier lifting, and legendary job-site durability.

Do you have a preference on size (do you want something ultra-portable/compact that you can carry with one hand, or a larger wheeled unit), and does your workshop deal with fine dust (like drywall or sanding dust) that might require specialized fine-filtration bags?

My pick: Vacmaster Professional Beast 5-gallon

• Vacmaster Professional Beast Series 5-Gallon Wet/Dry Vac - $109.99 (Cleva US | Vacmaster, LawnMaster, Armor All)

For car detailing + workshop cleanup around $100, I'd go with the Vacmaster Professional Beast 5-gallon. Current testing/reviews consistently put the Beast near the top for budget shop vacs, with excellent suction in a compact package.

Why I like it for your use:

• Very strong suction for its size.
• 5-gallon tank is plenty for car interiors, sawdust, chips, dirt, and general shop messes.
• Compact enough to move around a vehicle easily.
• Wet/dry capability.
• Good choice if you want power rather than simply the biggest tank.

One caveat: independent testing found that the Beast can occasionally clog on large/bulky debris, so it isn't my first choice if you're routinely sucking up big wood chunks or construction debris.

Two excellent alternatives

• RIDGID 4-Gallon 5.0 HP Portable Wet/Dry Vac with Car Cleaning Kit - $99.00 (Home Depot)

• DEWALT Stealthsonic 9-Gallon 5 HP Wet/Dry Vac - $99.00 (Lowe's)

• CRAFTSMAN 10-Gallon 5.5 HP Wet/Dry Shop Vac - $99.98 (Lowe's)

• Best specifically for cars: RIDGID 4-gallon with the car-cleaning kit. It's compact and includes a car nozzle, making it particularly convenient for interiors.

• Best if workshop use dominates: CRAFTSMAN 10-gallon 5.5 HP at about $100 gives you substantially more capacity.

• Best if noise matters: DEWALT Stealthsonic 9-gallon is currently around $99 and is an unusually compelling deal at that price.

Bottom line: For a single vacuum that has to do both car and workshop duty, I'd buy the Vacmaster Beast. If you expect lots of sawdust, wood chips, and larger debris, I'd spend the ~$100 on the Craftsman 10-gallon instead.

For around $100, you can get a surprisingly fierce wet/dry vac that handles heavy workshop debris (sawdust, drywall bits, metal shavings) and sucks ground-in dirt and gravel out of car floor mats with ease.

The top options right in that sweet spot balance raw power, hose length, and portability:

1. • RIDGID 4-Gallon 5.0 Peak HP Portable Shop Vac (WD4070)Go to product viewer dialog for this item. – Available at The Home Depot for roughly $79 to $90, this is widely considered the gold standard for compact power. It packs a massive 5.0 peak horsepower motor into a portable size, features a locking hose that won't pull loose mid-clean, and comes with a dedicated car nozzle for upholstery.
2. • DEWALT 4-Gallon 5.0 Peak HP Poly Wet/Dry Vacuum (DXV04T)Go to product viewer dialog for this item. – Hovering right around $95 on The Home Depot or Amazon, this features a brilliant toolbox-style rectangular shape. It has a heavy-duty 5.0 peak HP motor, an ultra-flexible 7-ft hose, a 20-ft power cord, and onboard storage that makes it exceptionally easy to toss in the trunk or carry around a tight workshop.
3. • Shop-Vac 10-Gallon 4.5 Peak HP Wet/Dry Vacuum Go to product viewer dialog for this item. – If you find yourself prioritizing workshop capacity over portability, you can often find a 10-gallon mid-size Shop-Vac discounted on Walmart for about $85. It gives you a wider 1.5-inch hose diameter to prevent clogging on larger wood chunks or leaves, plus a tank drain for wet messes.
4. • Stanley 6-Gallon 4 Peak HP Wet/Dry Vac Go to product viewer dialog for this item. – A stellar budget choice usually priced around $50 to $76, frequently stocked at Best Buy or online. It gives you a larger capacity tank than the DeWalt/Ridgid compacts without sacrificing too much maneuverability, though the hose and build feel a bit more entry-level.

Do you prefer a smaller, highly portable unit that's easy to lug into the backseat of your car, or a larger-capacity drum that won't need to be emptied as often in the workshop?

For around $100, I’d prioritize a real shop vac with good airflow, a reasonably wide hose, and enough capacity for workshop debris—not just peak horsepower.

🏆 My pick: RIDGID 4-Gallon 5 HP

• RIDGID 4 Gal. 5.0 Peak HP Portable Shop Vacuum - $99.00 (Home Depot)

At $99, this is probably the best match for both car detailing and workshop use. It has a 5 HP motor, is compact enough to maneuver around a vehicle, and—importantly—this particular package includes a fine-dust filter and car-cleaning kit.

For a workshop, the 4-gallon tank is somewhat small, but for a mix of sawdust, dirt, chips, and car debris it's a good compromise.

Other excellent choices

• Stanley 6-Gallon 4 HP Wet/Dry Vacuum - $57.99 (The Home Depot)

• Vacmaster Professional Beast 5-Gallon - $109.99 (Cleva US | Vacmaster, LawnMaster, Armor All)

• PORTER-CABLE 10-Gallon 5 HP Wet/Dry Vacuum - $88.99 (Tractor Supply Company)

• BAUER 9-Gallon 4.5 HP Wet/Dry Vacuum - $79.99 (HarborFreight)

• Best value — Stanley 6-Gallon: around $58 right now. Car and Driver named the Stanley 6-Gallon its best everyday shop vac, praising its capacity, maneuverability, and low price.

• Best power/compactness — Vacmaster Beast: about $110, slightly above your target, but its 6 HP motor and compact 5-gallon body make it an attractive step-up.

• Best workshop capacity — PORTER-CABLE 10-Gallon: currently $89, with a 5 HP motor. Better if workshop cleanup is more important than portability.

• Best big bargain — BAUER 9-Gallon: $79.99, with 4.5 peak HP. A lot of capacity for the money.

What I'd buy

Mostly car + occasional workshop: RIDGID 4-gallon 5 HP. 50/50 car and workshop: Stanley 6-gallon 4 HP—I'd save the $40. Mostly workshop/heavy debris: PORTER-CABLE 10-gallon 5 HP.

One thing I'd spend extra on: a good detailing attachment kit with a narrow crevice tool and soft brush. That's often more useful for getting between seats, around vents, and under seats than another 1 HP of advertised motor power.

For one vacuum to handle both car detailing and workshop cleanup, I’d buy the Stanley 8-Gallon 5 HP. It hits the sweet spot of power, capacity, and price.

Stanley 8 Gallon 5 HP Wet/Dry Vacuum

$89.81

My picks around $100

Stanley 8 Gallon 5 HP

DeWalt 6 Gallon 4 HP

$74.56

Bauer 9 Gallon 4.5 HP

$79.99

Stanley 6 Gallon 4 HP

$57.99

Bauer 5.5 Gallon 5 HP

$79.99

Why the Stanley 8-gallon gets my vote: independent testing of the Stanley 6-gallon found strong measured airflow/suction and particularly good performance on sand, gravel, and construction debris. www.techgearlab.comwww.caranddriver.com The 8-gallon version gives you more room for workshop debris without getting into the huge 12–16 gallon machines.

For your car, I'd also make sure you get a small-diameter detailing hose/crevice and brush attachments. The standard 1-7/8" hose is great for the workshop, but a smaller hose makes getting between seats and around the console dramatically easier.

If you want to spend as little as possible: get the Stanley 6-gallon for ~$58. It's probably the best dollar-for-dollar choice.

If you want maximum power under $100: I'd look closely at the Bauer 5.5-gallon 5 HP or Shop-Vac 8-gallon 6 HP.

If you tell me whether you care more about suction power, quietness, or car-detailing attachments, I can narrow it to the single best one.

For around $100, you can get a phenomenal wet/dry vacuum that bridges the gap between deep-cleaning a car interior and swallowing heavy workshop debris like sawdust and wood chips.

The best options in this price range balance raw power, a sensible footprint, and good included attachments:

Craftsman 6-Gallon 3.5 Peak HP Wet/Dry Vac (CMXEVBE17584) — Priced right around $60 to $90, this is one of the best sweet-spot vacuums for a garage or small workshop. It features an integrated on-board storage design for the hose, cord, and accessories, meaning it won’t become a tangled mess in your workspace. It includes a car nozzle and utility nozzle, making it nimble enough for tight car floors while packing enough punch for general shop debris.

RIDGID 4-Gallon 6.0 Peak HP Wet/Dry Vac (WD4080) — Usually hovering right at the $100 to $110 mark at The Home Depot , RIDGID is legendary for durability. This 4-gallon model punches way above its weight class with a massive 6.0 peak horsepower motor. A killer feature for workshops and car detailing is that the power head detaches to double as a handheld leaf/debris blower. It has great suction lift and a sturdy wheel configuration that won't easily tip over when you're dragging it around a car.

Bauer 6-Gallon 4 Peak HP Wet/Dry Vacuum — Available through Harbor Freight Tools for around $55, this is a heavy-duty budget champion. It gives you a larger 6-gallon capacity and 4 peak horsepower, making it an incredible value if you want maximum tank space and solid suction without breaking your $100 budget. It comes with onboard accessory storage and a flexible, kink-resistant hose.

Armor All 2.5-Gallon 2 Peak HP Wet/Dry Vacuum (VOM205P) — If your priority leans heavily toward car detailing over large-scale workshop cleanup, this compact orange powerhouse typically costs about $40 at Walmart . It's lightweight (~ 6 lbs) and comes with a specialized automotive accessory kit (including a claw nozzle and detail brushes). However, keep in mind that the smaller 2.5-gallon capacity means you'll be emptying it more frequently if you are cleaning up heavy sawdust or large liquid spills in a workshop.

If you want to narrow this down, let me know:

• Do you care more about maximum suction/capacity for heavy workshop debris or a compact size with great car-detailing attachments?
• Do you prefer to shop at a specific retailer like Home Depot, Lowe's, or Walmart?

For around $100, I’d prioritize a corded shop vac with strong airflow, a decent hose, and enough capacity for workshop debris. For your mix of car cleaning + workshop cleanup, my top pick is:

DEWALT Stealthsonic Quiet 6-Gallon 4 HP Wet/Dry Shop Vacuum

$84.98

🏆 Best overall: DEWALT Stealthsonic 6-gallon

$84.98 at Lowe’s right now. It gives you a 6-gallon tank and 4 HP motor, while being notably quieter than typical shop vacs. That's a particularly nice combination if you're using it around a car or spending a lot of time in the workshop.

• Stanley 5-gal — $47.99: Best bargain if keeping the price low matters most.
• HART 6-gal 5 HP + car kit — $84.97: Particularly compelling for your use because it includes car-cleaning accessories.

My ranking for you:

1. 🥇 DEWALT Stealthsonic 6-gal — best combination of power, capacity and noise

4. CRAFTSMAN 5-gal — best value

One important tip: don't choose based solely on “peak HP.” Airflow/CFM, hose diameter, filtration and attachments matter a lot for actually cleaning a car and sucking up workshop debris. Car and Driver's 2026 testing similarly recommends the Stanley 6-gallon as its everyday-use pick, while emphasizing that shop vacs are particularly well suited to garage/workshop debris.

If you want maximum suction specifically for sawdust, metal shavings, dirt and car interiors, I'd spend the ~$85 on the DEWALT Stealthsonic.

For cleaning both a car interior and a busy workshop, you want something with strong suction (high air watts/CFM), a decent hose reach, and a compact enough footprint to maneuver around tight spaces like footwells and crowded workbenches.

Around the $100 price point , you can get a phenomenal mid-sized wet/dry vac that punches well above its weight class. Here are the best options that fit your budget:

• Price: Around $85 - $99
• Why it's great: This is arguably the ultimate sweet-spot vacuum for a garage and car. It features a 3.5 peak HP motor, a 7-foot hose, a 10-foot power cord, and comes packaged with both a utility nozzle and a dedicated car nozzle. It also features balanced top-handle storage, rolls smoothly on swivel casters, and easily converts into a blower for clearing out your workspace when you're done.

Add to list

• Price: Around $109 (frequently found right at or just under budget with promotions)
• Why it's great: If raw power is your main priority, RIDGID’s 5.0 peak HP compact motor delivers massive suction (176 air watts) in a smaller 4-gallon tank. It includes a generous 20-foot power cord (huge for reaching across a driveway or deep into a large shop without an extension cord), heavy-duty casters, and a locking hose that won't pop off mid-job.

Add to list

• Price: Around $55
• Why it's great: If you want to spend well under $100 and still get a capable machine, Walmart’s Hyper Tough 5-gallon unit delivers 4.0 peak HP, a 12-foot power cord, and solid baseline performance for sucking up sawdust, car dirt, and liquid spills without breaking the bank.

Recommendation:

Go with the Craftsman 6 Gallon Go to product viewer dialog for this item. if you value great included car/utility attachments and an easy overall size for storage. Step up to the RIDGID 4 Gallon Go to product viewer dialog for this item. if you want maximum raw suction power and a much longer power cord for bigger workspaces.

If you'd like, let me know:

• Do you prefer a longer power cord or a larger tank capacity?
• Are you planning to pick this up locally or order online?

I can check exact local availability or recommend specific filter types (like fine dust or HEPA bags) for your workshop needs.
