What experts didn't like
This was the worst vacuum for picking up dry debris. It left behind large pieces and only cleaned about 55 percent of the mulch in one pass.

The only downsides are that it’s obviously not as portable as what a cordless model could provide, the power cable should’ve been longer than 10 ft. and also, a power adapter for the cigarette lighter could’ve been supplied.
- Best Handheld Vacuums
For only 10 feet, it means you have to keep adjusting the power source every now and then and this may be cumbersome in the long run.
- Vacuum Cleaner Hub
Hose often does not stay firmly in place while using the Blower functionality
- Automotive Ward
The hose sometimes blew off while using it as a blower.
- Vacuum EZ
The vacuum is not meant for large debris pieces, better for household jobs only.
- Home Growth Ideas
10′ extension cord is a bit short.

An Overview On Wet Dry Vacuums

What do flooded basements, messes in your workshop and the ashy aftermath of a BBQ have in common? If you’re thinking that they’re all major annoyances, you’re not wrong — but they’re also all jobs for a wet/dry vacuum. 

Wet/dry vacs, or shop vacs, are common accessories in woodshops, but they can also help out with lots of different messes. These versatile appliances have more powerful suction, plus tougher filters and sturdier canisters than a standard vacuum. They can pick up debris like nails and screws, and you can use them to clean up wet messes. Puddles from a leaky dishwasher or water basins that need emptying don’t stand a chance against a wet/dry vac. 

Standard vacuums operate using a relatively simple process. Once you turn them on, the motor receives electricity that drives the fan and the brush roll (that spiky part that goes deep into your carpet and gets tangled with hair). After the motor starts running, it creates an area of low pressure behind the fan, which generates the suction you need to chase down those dust bunnies. Your messes move into the vacuum’s removable dust bag or canister, and poof! You’ve got a clean floor. 

Shop vacs have different power levels for different size messes.

“A wet/dry vacuum’s power is measured in Sealed Pressure (or SP) units,” says Vicki Liston, a home improvement expert and host of “On The Fly…DIY,” an award-winning show with project tutorials. “Vacs with an SP rating over 75 should be able to handle almost everything you throw at them. “

Cubic Feet per Minute, or CFM, is your vac’s airflow rating.

“If you’re sucking up tiny particulates like sawdust, opt for something that’s at least 90 CFMs,” adds Liston. “If you’re vacuuming up heavier items like nuts and bolts, look for an Air Power (AP, also called Air Watts) rating over 250.” 

Another difference between wet/dry vacuums and standard vacuums is the motor placement. Instead of sitting inside of the vacuum’s canister, a wet/dry vac’s motor sits on top of the canister. This design allows anything that you suck up through the hose to go directly into the canister, instead of passing over the motor. It’s the reason that wet/dry vacs can safely pick up water — if the water was moving through electrical or mechanical parts, it could create a dangerous electrical shock. 

Some wet/dry vac models also vent air through an opening in the canister. With the help of a few accessories, you can turn this opening into a blower on many shop vacs. Vacs that convert into a blower make your autumn leaf chores much easier.

DWYM Fun Fact

The history of vacuums might sound boring, but trust us — it doesn’t suck. Windy City resident Ives McGaffey patented the precursor to the modern vacuum on a warm summer day in 1869. It was called a “sweeping machine,” and it was designed to clean rugs. 

The sweeping machine was a far cry from our modern wet/dry vacuums, but Ohio janitor James Spangler brought us one step closer in 1907. He realized that his carpet sweeper was kicking up dust and causing his chronic coughing fits, so he buckled down with his Midwestern work ethic and created an alternative. Spangler stapled a soap box to a broom handle, tacked on an old fan motor and added a pillowcase as a dust collector. His cough disappeared, and he received his patent in 1908. 

After World War II, a new vacuum arrived on the scene. The first wet/dry vacuums were enormous metal appliances, and they were mostly used in industrial and woodshop settings. It took a while, but engineers finally developed smaller units for residential areas. The trickiest part was muffling the loud “screaming” noise the wet/dry vacuums made when they turned on! 

Today’s wet/dry vacs aren’t the quietest appliance around, but they definitely don’t sound like a low-budget horror movie.

The Wet Dry Vacuum Buying Guide

  • Before you buy, think about where you’ll get the most use out of your wet/dry vacuum. If you’re buying it for heavy-duty construction projects, a larger unit is appropriate. A handheld vac is fine for everyday jobs like vacuuming your car or sucking up spilled liquids in your kitchen.
  • Wet/dry vacs have an unmatched level of versatility and they can pick up far more debris than a standard vacuum. However, that convenience comes at a cost. Most wet/dry vacs are much heavier and bulkier than a standard vacuum, so make sure you take a look at the unit’s weight when you purchase it. You’ll also want to account for the weight of the dust, dirt and junk you’ll be picking up. Make sure you can comfortably lift and handle that weight. Most vacuums that weigh over 20 pounds will have something in the neighborhood of a 16-gallon capacity, while vacuums under 10 pounds can pick up roughly 2.5 gallons of mess. 
  • Check out the length of the vacuum’s hose and power cord. Unless you want to stop every few minutes and find a new power outlet, you’ll need a nice long cord for vacuuming up larger areas. A 12-foot cord works well for bigger rooms, while a six-foot cord is easy to store and makes small jobs simple and quick. 
  • Will you need a wet/dry vac with wheels? Cleaning up an entire construction area means you’ll need some help moving the vac around, but wheels can get unwieldy if you need to pick up the vac and get between seats in your car. 
  • Wet/dry vacs come with accessories galore so that you can get the most out of your investment. A fully accessorized wet/dry vac will come with a brush, a crevice tool, a detail brush and a deluxe car nozzle. It’s a great pick for cleaning out your car. Others will add multiple extension wands, so they’re ideal for reaching every space in your woodshop. 
  • A wet/dry vacuum’s design prevents water from crossing paths with the interior electrical components, but you could be in for some trouble if the external cord winds up in a puddle. Investing in a Ground Fault Circuit Interrupter (or GFCI) is the smartest thing you can do to stay safe while using your vacuum’s wet mode. GFCIs trip electric power in as little as 1/40 of a second, preventing shocks or reducing the shock’s damage.
  • Three-pronged electric outlets have built-in GFCIs, but there are also portable versions that you can plug into two-pronged outlets, as well as attachment plugs that incorporate the GFCI module. Portable GFCIs and Cord-Connected GFCIs are available online or at your local hardware store.
  • Although wet/dry vacuums are designed differently than standard vacuums, they still use filters. “It wasn’t until I aerated a room with drywall dust that I realized just how critical correct filter size was in wet/dry vacuums,” says home improvement pro Vicki Liston. “Before starting every job, consider the debris size and install the appropriate filter.  They’re available from ‘fine’ to ‘large’ and ‘wet’ for damp environments.”
  • You’ll also have to swap out your filters depending on what type of job you’re doing, and you’ll need to clean the filters regularly or buy replacements. Double-check the cost of the filter replacements before you buy your wet/dry vacuum. 
  • Cleaning your filter is essential if you want your vacuum to function at its highest level. Wet filters are made from foam, and you’ll have to set them aside to dry after every wet mess you clean up. After they dry, give them a good shake to knock off any debris. If it’s still dirty, hold it under running water for a few minutes. Make sure you rinse from the inside of the filter to the outside. Let it sit for a long time in a room with low humidity — this prevents mold from forming.  
  • Cleaning dry filters is a bit simpler. If they’re reusable, you can knock loose any debris and call it a day. If you just finished a big job, rinse them with water on both sides and give them plenty of time to air dry. Using a disposable filter? Just toss it and start over with a new filter the next time you’re vacuuming.
  • The standard filter you’ll use for dry messes will vary depending on which wet/dry vac you choose. Some come with HEPA filters. These filters force air particles through the ultra-fine mesh, and they’re great at picking up small particles and allergens. It helps prevent dust from spreading as you’re cleaning up, making it an ideal filter for anyone with allergies or asthma. 
  • You’ll have to dump some wet/dry vacs upside down to clean out the canister. Other models have dust bags that you can empty or remove instead of flipping the whole canister upside down. Make sure your wet/dry vacuum is easy for you to lift and tilt before you hand over your cash.
