How To Choose The Best Cordless Shop Vac
A cordless shop vac is only as good as the job it can finish on one charge. That means you need to look at three things together: tank size, battery runtime, and the battery platform you are already in.
Match the tank size to your mess
A 2.6-gallon tank is fine for a single car interior or a day’s drywall dust. If you are cleaning a full workshop floor or sucking up a flooded planter, the 9-gallon EGO avoids multiple trips to empty the bucket.
Look at battery ecosystem, not just the tool
If you already own Milwaukee M12, RYOBI 18V, or EGO 56V tools, buying a bare-tool vac that drops into that battery family saves you the cost of extra batteries and chargers. The trade-off is that some platforms have a smaller battery cell, which can limit how long the vac runs on high power.
Check the filter type for fine dust
A HEPA filter (a high-efficiency filter that traps 99.7% of particles down to 0.3 microns — the tiny, inhalable dust specks) matters if you are sanding or sweeping concrete dust. A standard foam filter works for wet spills and larger debris but will let fine dust recirculate into the air.

In‑Depth Reviews
1. EGO Power+ Shop Vacuum WDV0900
A 9-gallon cordless vac that runs up to a full hour and pulls like a corded model.
This is the pick that makes you forget you are unplugged. The EGO delivers 110 CFM of airflow (cubic feet per minute — the volume of air it can move) for a 100-inch lift (how many inches of water it can hold vertically), numbers that buyers report match their old corded Ridgid on high mode. The 9-gallon tank has a drain plug so you do not have to tilt the whole unit to dump out water. It runs up to 60 minutes on ECO, 30 minutes on high, or 20 minutes on turbo when paired with the recommended 2 x 6.0Ah ARC Lithium batteries (sold separately).
Owners mention being genuinely surprised at how quiet it is for the power, and the wireless remote clipped to the hose handle lets you switch between Low, High, and Turbo without walking back to the unit. One owner says he was able to vacuum an entire car on a single 2.5Ah battery (a smaller-than-recommended battery). The onboard storage holds all the nozzles, extensions, and hose. The trade-off is that the hose is 1-7/8 inches — some reviewers wish it were 12 to 15 feet instead of the shorter included length — and the rear casters could be larger for rolling over uneven garage floors.
Real power margin
- 110 CFM and 100-inch lift rival corded shop vacs
- 9-gallon tank with drain plug — no tilting to empty water
- Wireless remote on handle for mode switching
What to know before you buy
- Batteries and charger sold separately — only for EGO 56V users
- Hose length could be longer for large garages
- At 24.4 x 16.5 x 24.6 inches, it takes up floor space
Best suited for: Anyone already in the EGO 56V ecosystem who wants corded-level suction from a cordless vac, or a pro needing quiet, continuous runtime for medium-to-large jobs.
One real limitation: The battery-upfront cost is significant if you are not already on the EGO platform, and the hose length is shorter than ideal for a 9-gallon tank.
2. RYOBI ONEAND 18V Link Cordless 3 GAL. Wet/Dry Vacuum PCL734B
The largest tank in the mid-range tier holds 87% more than the compact Milwaukee.
You get a 3-gallon tank here — a full 87% more capacity than the Milwaukee 1.6-gallon model. That means fewer trips to empty the bucket when you are cleaning up a workshop floor or drying out a car. The vac is part of RYOBI’s 18V ONE+ system, so it shares batteries with a huge lineup of other tools if you are already in that family.
The catch is the weight. At 12.55 pounds, it is 57% heavier than the Seesii (8 pounds), which matters when you are carrying it up stairs or out to the driveway. It is a bare-tool-only unit — battery and charger are sold separately. Customers note that the hose is 1.8 meters (about 5.9 feet), which is standard for this class but does limit reach without moving the unit. It has a HEPA filter, which traps fine dust.
Capacity champion: The best option if you need a 3-gallon tank and are already invested in RYOBI’s 18V batteries, but be ready for its heavier build compared to smaller rivals.
Reach for this if: Your cleaning jobs regularly fill more than 2 gallons and you want a HEPA filter without stepping up to the 9-gallon class.
Look elsewhere if: Portability is your top priority — the 12.55-pound body gets cumbersome to carry around a car or up stairs.
3. BOSCH GAS18V-3N 18V Cordless Wet Dry Vacuum
An 18V HEPA-certified dust extractor that keeps suction going even as the filter loads up.
Bosch’s Rotational Airflow Technology is the standout feature here — it prevents dust and debris from choking the filter, so the suction stays strong as you work instead of fading after a few minutes. The certified washable HEPA filter (traps 99.97% of particles down to 0.3 microns, the standard for drywall dust and allergens) makes this a legit dust extractor for woodworking and renovation cleanup. It runs up to 24 minutes on a 6.0Ah battery (sold separately).
The trade-off: battery runtime is shorter than the LIGO or ReliaRoads when running on high, and the hose is 5.25 feet, which is a 31% longer reach than the Milwaukee’s 5-foot hose but still requires the unit to sit close to the work area.
Filter-first design
- Rotational Airflow Technology maintains suction longer than standard filters
- Certified HEPA filter traps 99.97% of fine particles
- Part of the AMPShare multi-brand battery system
Drawbacks
- 24-minute runtime is shorter than many competitors on high power
- Bare tool — batteries and charger sold separately
- 2.6-gallon tank fills faster than the RYOBI 3-gallon
Verdict: The right choice if you need a HEPA-certified vac for fine-dust work on a job site, but be prepared to swap batteries mid-day on larger cleanups.
4. Milwaukee 0960-20 M12 FUEL Brushless Cordless 1.6 Gal. Wet/Dry Vacuum
A M12 FUEL brushless compact vac that fits in a toolbox yet lifts water 42 inches.
Do not let the 1.6-gallon tank fool you — this Milwaukee pulls 42 inches of water lift (it can hold a column of water 42 inches tall), which is genuine suction power for both wet and dry applications in a body that measures just 15 x 13 x 12 inches. If you are already in the M12 ecosystem, this drops into your existing battery lineup and stores vertically with a stackable design. The 5-foot hose is the shortest in this group, so this is not the pick for cleaning a whole garage floor without moving it.
Reviewers appreciate the onboard accessory storage and the fact that it is compatible with a fleece dust bag (model 49-90-2016) for quicker dry-dust disposal. Buyers who have the batteries say it is a no-brainer for small cleanups, car interiors, and tight spaces where a larger vac does not fit.
Tight-space specialist: Ideal for M12 users who need a compact, powerful vac for small jobs and quick pickups, but the 5-foot hose and 1.6-gallon tank limit it to close-range cleaning.
Perfect for: Milwaukee M12 users who want a stackable, wall-mountable vac for small spaces — car, van, workbench.
Not for: Anyone who needs a full-day runtime or a big tank for large debris.
5. Seesii Cordless Shop Vac Wet and Dry K-903
A 2.6-gallon vac with two batteries and a brushless motor that outlasts traditional models.
At 8 pounds, the Seesii is 57% lighter than the 12.55-pound RYOBI, which makes a real difference when you are carrying it up stairs or moving it from car to garage. It comes with two 4.0Ah batteries (amp-hours — a measure of energy storage; higher means longer runtime), so you get 20 minutes on HIGH gear or 40 minutes on LOW gear without waiting for a recharge — a 50% longer runtime on high compared to the ReliaRoads’ 30 minutes. The brushless motor runs cooler and lasts longer than traditional motors. It offers dual suction modes: 9kPa (kilopascals — a metric measure of suction force; higher is stronger) for routine cleaning and 15kPa for pet hair and stubborn dirt.
The 3-in-1 function (wet pick-up, dry pick-up, blowing) covers the basics. Reviewers point out that the included shoulder strap and wheels make it easier to move around hands-free than carrying a handheld body. The washable HEPA-rated filter traps 99.7% of dirt. The trade-off: it measures 14 x 6 x 12 inches, and at 70 decibels it is not the quietest option on this list.
What you get at this price
- Two 4.0Ah batteries included — no separate purchase needed
- Only 8 pounds, significantly lighter than the RYOBI
- Brushless motor with dual suction modes (9kPa / 15kPa)
The trade-off
- 20-minute runtime on high is shorter than some competitors
- No battery ecosystem compatibility — stand-alone system
- 70 dB noise level is higher than the EGO
Who it beats: Budget-minded buyers who want a complete kit with two batteries and a brushless motor, without needing to own a battery platform already.
6. LIGO 20V Cordless Shop Vac Wet and Dry MWW205-20V-10L
A complete cordless kit — battery, charger, HEPA filter, foam filter — included in one box.
LIGO packs everything you need to start cleaning right from the start: a 4.0Ah battery, charger, washable HEPA filter, and a foam filter for wet pickups, plus the tube, brush, and mounting hardware. The 2.64-gallon tank is nearly identical in capacity to the Seesii, and the handheld form factor measures 14 x 6 x 12 inches, making it noticeably narrower (14% less in length) than the ReliaRoads’ 16-inch body. The 3-in-1 function covers wet, dry, and blowing duties.
Runtime is rated at up to 30 minutes, which matches the ReliaRoads and beats the Seesii’s high-mode runtime. The universal 20V battery pack is designed to work across the LIGO tool platform. One catch: the battery life is listed as 0.25 hours (15 minutes) in the technical specs, which seems like a conservative rating — real-world use with the 4.0Ah battery should be closer to the 30-minute claim. The included foam filter is useful for wet pickups, while the HEPA filter handles dry fine dust.
Ready-to-run value: A complete budget kit with both HEPA and foam filters, ideal for a first-time cordless shop vac buyer who does not want to source separate batteries or chargers.
Best for: A home garage user who wants a single-box solution with no extra purchases — just unpack, charge, and go.
7. ReliaRoads 20V Cordless Vacuum Cleaner Wet/Dry Shop Vac RCSV-20
A DeWALT 20V MAX-compatible vac with a 6.56-foot hose and 45 CFM airflow.
If you own DeWALT 20V MAX tools, this is the only vac on the list that drops into your existing battery system without an adapter. It delivers 45 CFM (cubic feet per minute — the volume of air moved) at 12.1 kPa (kilopascals — a metric suction force measure; roughly equals 48.6 inches of water lift) — enough for wet spills and car interiors. Designed to work with DeWALT batteries up to 5Ah, it achieves up to 30 minutes of runtime. The hose is 6.56 feet long and 1-1/4 inches in diameter, giving you the longest reach in the smaller-capacity class (31% longer than the Milwaukee’s 5-foot hose).
The 2.65-gallon tank is nearly identical to the Seesii and LIGO. The included accessory kit is generous: soft hose and connectors, multi-purpose nozzle, crevice tool, sofa brush, and an extra-long crevice tool. The blowing feature clears sawdust from hidden spots after vacuuming. The dimensions (16 x 11 x 11 inches) make it slightly bulkier than the LIGO (14 x 6 x 12 inches). Shoppers say that the washable HEPA filter keeps maintenance simple. The trade-off: since it is a bare tool, you need to already own a DeWALT 20V battery and charger.
Why DeWALT owners want this
- Works with DeWALT 20V MAX batteries up to 5Ah
- 6.56-foot hose is the longest in the sub-3-gallon class
- 45 CFM and 12.1 kPa suction handles wet and dry debris
Limitations
- Bare tool — battery and charger not included
- 16-inch length is bulkier than the LIGO for storage
- 30-minute runtime is average for this class
The DeWALT ecosystem pick: The most practical choice if you already own DeWALT 20V batteries and want a cordless shop vac that shares the same power source, with the longest hose in its class for flexible reach.
Understanding the Specs
CFM vs Water Lift vs kPa
CFM (cubic feet per minute) measures how much air the vac moves — higher CFM is better for large debris like sawdust and wood chips. Water lift (measured in inches) measures how hard the vac pulls — a 42-inch lift like the Milwaukee means it can hold a column of water 42 inches tall, which matters for stubborn dirt and wet spills. kPa (kilopascals) is a metric unit that measures the same suction force; 12.1 kPa equals roughly 48.6 inches of water lift.
Gallon Capacity and How Full You Can Fill It
Tank size (measured in gallons) tells you the theoretical capacity, but real-world use is less — a foam or HEPA filter takes up interior space, and the auto-shutoff stops suction before the tank overflows. For wet pickups, a 1.6-gallon tank like the Milwaukee fills fast; the 9-gallon EGO handles a flooded planter without needing to dump mid-job.
