A Shop vacuum picks up where household models drop off. When your cleanup involves liquids, automotive debris, job site materials, or heavier household waste, you need a wet dry vacuum. Don't worry, you got this. First, consider the mess. The larger the job, the bigger and better vac you'll need in terms of peak horsepower and capacity. For bulk pickup, a larger tank will save you from repeatedly emptying the unit. For smaller tasks like household maintenance or auto cleaning, a smaller model will get the job done and store away easier. Wet dry vacuums use filters ranging from general to fine grade. Choosing one comes down to the job at hand. Cartridge filters are great for bulk wet or dry pickup, but can require tank cleanup. A general duty collector bag keeps your tank clean and makes disposal easy, as long as debris is dry. Foam filters handle wet pickup. And for a mixture of wet and dry debris, a tear resistant wet or dry collection bag separates wet and dry waste in one handy container. For fine debris like drywall dust, you'll need a high efficiency or HEPA-rated filter. You can also combine a HEPA cartridge with a HEPA collector bag for maximum dual dry filtration. Next, think about the accessories you'll need. They give your vac an advantage, handling different spaces, materials, and surfaces. Examine the size of your tank port to figure out which accessories are compatible with your wet dry. A 2 and 1/2 inch port allows you to select multiple sizes using an adapter. And if you're using a maximum or shop vac vacuum, filters and accessories are all interchangeable. A longer crush-proof hose adds reach and prevents step damage. The 1 and 1/4 inch turbo nozzle makes upholstery and car interior a breeze. From wands to brushes, accessory options are nearly endless. Look for tools that will make cleanup more effective. Finally, consider the built-in features. For sizable wet pickup, consider a vac with a built-in pump out feature. This allows for continuous pumping beyond tank size, using a standard garden hose. If you're dealing with basement flooding, a pump vac may be a better bet. Poly tanks avoid static, while stainless steel tanks prevent odor absorption. A blower port helps with interior car cleaning or leaf blowing. If noise is a factor, choose a vac with a lower decibel rating. Staying in one place? Try a stationary or drop away dolly model. If mobility is important, consider how onboard tools are stored, how the host connects, and the length of the electrical cord. With unbeatable durability and versatility, the right wet dry Shop vacuum will remove the stress from your next big mess. Whatever you're cleaning, don't worry, you got this.
