Keep remote farm buildings clean without an outlet. Our guide reviews the 7 best cordless wet/dry vacs, focusing on power, battery life, and capacity.
There’s nothing quite like discovering a water line to a stock tank has developed a slow leak overnight, creating a muddy mess in the far corner of the barn. Or finding that a bag of feed has been chewed open by a rodent, scattering grain across the tack room floor. In these moments, dragging a 100-foot extension cord from the house is the last thing you want to do.

Why Cordless Vacs Are a Farm Building Essential
A farm is a collection of controlled messes, and the buildings furthest from the house are often the messiest. Spilled feed, tracked-in mud, sawdust from a quick repair—it all adds up. Relying on an extension cord is not just a hassle; it’s a trip hazard around livestock and a pain to wind up with cold, muddy hands.
The real magic of a cordless vac is its immediacy. A small spill can be cleaned in two minutes, preventing it from attracting pests or becoming a bigger, stickier problem later. You’re far more likely to tackle these small jobs right away when you can just grab the vac and go.
This isn’t just about floors, either. Think about cleaning out the cab of your tractor, which is always full of dirt and chaff. Or sucking cobwebs and dust out of a chicken coop between flocks. The portability of a cordless unit makes these specific, awkward jobs infinitely easier and faster.
DeWalt DCV581H: Versatile Corded or Cordless Power
The standout feature of the DeWalt is its dual-power capability. It runs on their common 20V MAX battery platform, but it can also be plugged into a standard wall outlet. This flexibility is a massive advantage on a small farm.
You can use it cordlessly in the remote shed, then plug it in for a long, deep clean in the main workshop without draining your batteries. This hybrid approach means you’re never caught without power. It’s a practical solution for someone who needs both off-grid convenience and unlimited runtime near an outlet.
While it’s not the most powerful suction monster on battery alone, it’s more than enough for common farm debris like spilled grain, wood shavings, or muddy water. It also includes a HEPA-rated filter, which is great for trapping fine dust. The DCV581H is the perfect "do-it-all" option if you can only justify buying one shop vac for your entire property.
Milwaukee M18 0880-20: Max Suction for Heavy Debris
When you need raw, uncompromising power far from an outlet, this Milwaukee is the answer. It’s designed for heavy-duty cleanup, with suction that rivals many corded models. This is the vac you grab for sucking up wet, heavy bedding, wood chips, or a pile of spilled hardware.
It’s built tough, with a practical toolbox shape that makes it easy to stack and transport without tipping over. The hose and accessories store neatly onboard, so you’re not hunting for the crevice tool in the back of the truck. It feels like a professional-grade tool because it is.
That power comes at a cost: battery life. The M18 platform is robust, but this vac will drain a battery faster than a drill will. It’s wise to have at least one spare fully charged. For pure performance and tackling the worst messes, the Milwaukee 0880-20 is the undisputed champion of cordless suction.
Ryobi P3240 ONE+: Best Value for an Existing System
If you’re already invested in Ryobi’s massive 18V ONE+ battery system, this vac is a no-brainer. The "tool-only" price is often incredibly low, making it an easy and affordable addition to your tool shed. It leverages the batteries you already own for drills, saws, and string trimmers.
Don’t let the price fool you; the performance is solid for its class. It’s perfectly capable of handling everyday farm cleanups, from sawdust on the workshop floor to cleaning out the bed of the UTV. It’s lightweight and simple to operate.
This isn’t the vac for a major flood, but for 90% of the quick cleanups you face, it’s more than adequate. The Ryobi P3240 is the best value on the market, providing good-enough performance for a fraction of the cost of premium brands. It makes cordless convenience accessible to almost any budget.
Makita XCV11Z: Compact LXT Power for Cabs & Coops
This portable Makita vacuum delivers powerful suction for wet/dry cleanup. Its brushless motor provides efficient performance and the HEPA filter captures 99.97% of particulates 3 microns and larger.
The Makita XCV11Z is all about portability and precision. It’s smaller, lighter, and quieter than most traditional "bucket" style vacs. This compact form factor is its greatest strength.
Think about the places a big, clumsy vac can’t go. This Makita is perfect for getting into the tight footwells of a tractor cab, cleaning shelves in a feed room, or tidying up a brooder without terrifying the chicks. Its efficient brushless motor also provides excellent runtime on Makita’s popular 18V LXT batteries.
You won’t be using this to drain a 10-gallon stock tank, as its capacity is limited. But that’s not its purpose. This is the specialist’s tool for detailed work in confined spaces, making it an ideal second vac for equipment and interior cleanups.
Ridgid HD0918 NXT: Large Capacity for Big Spills
Sometimes the problem is volume. A broken pipe, a knocked-over water trough, or a major roof leak requires a vac that can hold a lot of liquid. That’s where the 9-gallon Ridgid NXT shines.
This is a full-size shop vac that just happens to run on batteries. The large tank means you can tackle huge messes without stopping every two minutes to empty it. It sits on a caster base, so you can easily roll its substantial size across a concrete barn floor to the problem area.
Naturally, a vac this large is heavy and not something you’ll casually carry to a far field. It’s also thirsty for power, so having multiple Ridgid 18V batteries is a must for a big job. When your biggest off-grid challenge is large-volume spills, the Ridgid’s massive capacity is the solution.
Craftsman V20 CMCV002B: A Solid, No-Frills Option
The Craftsman V20 vac is the definition of a reliable workhorse. It doesn’t have the hybrid power of the DeWalt or the raw suction of the Milwaukee, but it offers a fantastic balance of performance, portability, and price.
It’s a straightforward, easy-to-use tool that does exactly what it’s supposed to. The 2-gallon tank is a good compromise between capacity and weight, making it easy to carry to wherever the mess is. If you’re already using Craftsman’s V20 tool line, it’s a seamless and dependable addition.
This vac rarely comes in first in any single category, but it’s never in last place, either. It’s a competent, all-around performer that you can count on. The Craftsman is a great choice for the farmer who wants a simple, effective tool without overthinking the decision.
Milwaukee M18 Backpack Vac: For Ultimate Mobility
Not all messes are on the ground. Dust and cobwebs accumulate on rafters, fans, and high shelves, creating fire hazards and poor air quality. The Milwaukee M18 Backpack Vac is a specialized tool designed to solve this exact problem.
By putting the motor and canister on your back, your hands are free to manage the hose and safely climb a ladder or navigate a cluttered loft. You can clean areas that would be impossible to reach with a traditional vac. It’s also fantastic for cleaning the inside of a combine or other large, complex machinery.
This isn’t your primary wet-spill vac, as its design is optimized for dry debris. But for its intended purpose, it’s revolutionary. For anyone with high ceilings, complex equipment, or a multi-level barn, this backpack vac offers unparalleled mobility and access.
Ultimately, the best cordless vac for your farm depends entirely on your most common messes and the battery ecosystem you already own. Choosing the right tool transforms cleanup from a chore you dread into a quick task you can handle immediately. That means more time for the work that really matters.
