Ive got a smaller Rigid vac with a 1 7/8” hose I believe. Do yourself a favor and get whatever the larger size hose id on the stepped up vac. Maybe 2.5” hose. The 1 7/8” hose, despite every adapter I’ve ordered and tried, connects to nothing. Answer from ralphy112 on reddit.com

r/Tools on Reddit: Shop Vac Size Recommendation
January 21, 2023 -

Hello all!

Before I became a homeowner the in-laws gifted us an Armor All 2.5 Gallon 2 Peak HP Wet/Dry Vac that has a measly 53 CFM and 47.4 IN water lift.

I’ve never been overly impressed with this unit from the beginning. There’s no collection bag. The top housing of the unit doesn’t seal well to the collection tank (therefore it’s not preforming to specifications). It’s nearly impossible to find a wet filter for this unit. It’s made by Cleva Hong Kong Limited which is or was being sued by Emerson Electric Company for patient infringement. Emerson Electric from what I understand manufacturers vacuums for Ridgid, Craftsman, etc.

Well, being a new homeowner I’ve had many expenses lately with one-time purchases so I’ve tried to use this Armor All wet/dry vacuum for as long as I could. I recently demolished a cinder block dividing wall (non load bearing) in the basement which had a sole purpose of holding coal to heat this late 1800’s home at one time. Since it’s negative space, I removed it. I’m left with quite a bit of small material after demolition. A lot of this fine material remains even after sweeping. Yet the Armor All wet/dry vacuum even struggles with this, among other tasks I’m noticing.

I’m frustrated with this unit and can now justify upgrading. While being frustrated, I may be going to the opposite extreme. I’ve potentially settled on 3 options below. However, from what I’m reading the size of these units below may be ‘overkill’ however I wouldn’t know as I don’t have much experience with different sizes of shop vacs.

I do not have a garage (but plan to have a detached one built within 1-2 years). For now, it would remain in the basement for storage where I have a decent amount of space. It’s where I keep a Yeti Tundra 45, a lawn roller (empty), top dressing rolling lawn spreader and an Ego lawnmower (only during the winter, I baby it). I don’t enjoy moving these heavy items to and from the basement but it’s not physically an issue. I do currently have gravel parking so if I decide to use it to vacuum our vehicles, it will be a challenge with a vacuum with wheels but again, that will change in the future.

I don’t know what the future uses will be with the new shop vac. This far, 7 months into homeownership I’ve used it as a dust collection for sanding our wooden deck, removing stale water from a water softener brine tank, cleaning air ducts vents, cleaning refrigerator coils and up until now, cleaning the cinder block demolition.

I’m interested in:

  • RIDGID 14 Gallon 6.0 Peak HP NXT Wet/Dry Shop Vacuum

  • DeWalt 16 Gal. 6.5 HP Poly Wet/Dry Vac

  • Craftsman 16 gal Corded Wet/Dry Vacuum 12 amps 120 V 6.5 HP

Based on the above information, are these sizes a great option for me or should I look at something smaller and if so, what size?

Thanks for your help!

r/BeginnerWoodWorking on Reddit: How big of a shop vac should I get?

My little portable shop vac I bought 10 years ago (before woodworking) just isn't cutting it anymore, and I'm looking to upgrade. I plan on putting a dust cyclone in front of it (still deciding between the rockler dust right and the dust deputy). I was currently going between these two shop vacs:

Amazon.com: CRAFTSMAN CMXEVBE17595 16 Gallon 6.5 Peak HP Wet/Dry Vac, Heavy-Duty Shop Vacuum with Attachments , Red : Everything Else

RIDGID 14-Gal. 6.0 Peak HP Wet/Dry Vac with Auto Detailing Kit : Industrial & Scientific (amazon.com)

My question is: do I even need that large of a capacity since most of the dust wouldn't make it into the vac? I also realize I eventually want a dust collector for the table saw but figure I'll start with the vac since I need something to clean up the floor anyways.

This probably belongs in r/furgal but fugured I would recieve a better answer here. So my apoligizes if this is the wrong sub.

This is for a typcial home garage not really anything large-scale but I want to r/BIFL (within limits) and not have to purchase another one for sometime but also not break the budget. I need it mostly for house remodeling (sanding drywall and rerouting), cleaning crawl spaces, and maybe dust collecting for carpentry projects in the future.

What should a first time home buyer consider in this scanerio and us there any specifics I should look for in models? What are the expriences with non brand and more affordable options in similar alternatives brands if the budget is tight? I.G. Black and Decker vs Soap-vac? Thanks

I have an older 4 gallon Ridgid shop vac which has been ok for small tasks, but really isn't big enough since I'm often picking up huge amounts of dog hair along with everything else. I was all set to order the current 12 gallon NXT model until I noticed the 14 gallon version is actually cheaper in Canada right now. It's higher power (6hp peak vs. 5hp peak) but also considerably heavier (22 lbs vs. 16.5 lbs net weight). Normally I wouldn't have even considered the 14 gallon model simply because it's heavier and more expensive, but now I'm debating whether the extra power would be useful. I'm mostly just concerned it might end up being too bulky and heavy since the 12 gallon model seems to be a sweet spot. I intend to keep the small shop vac, so I'm not as concerned about getting into really tight spaces, but I want to use the large one as much as possible.

I'd be very interested to hear some opinions on which size is preferable for home use.

r/Tools on Reddit: shop vac specs question: size vs HP and CFM
January 22, 2025 -

I want to purchase my first shop vac and one thing I've noticed is that for a given brand/model of vacuum (e.g. Ridgid HP NXT), the greater the rated volume, the higher the rated HP and CFM according to the manufacturer.

Does this mean that the larger sizes of a given brand/model will have greater suction power than the smaller sizes, or are the higher HP motor and listed CFM necessary to achieve equal suction power given that the vacuum is larger?

Another way of asking my question is: do I have to buy the largest vacuum of particular brand/model to get the best suction power?

Ignore the HP ratings they're always bullshit on these. CFM is helpful though, but one thing they don't mention that would also be helpful is the suction as well. Mi-T-M does provide an inches water lift rating (as well as providing real actual HP values) but they cap out a little over 100CFM. I feel like it's just a general practice to put bigger better motors and impellers on bigger units just because. Kind of sweetening the pot to make the model stand out more against others beyond size of the can it's on, and justify pricing models. Though Ridgid has a 10-gal with 160 CFM using a 6.0 "peak" motor while having 12 and 14 gallon models with the same peak that actually has a little less CFM. If you're looking for more power in a smaller package their 10 gallon steel drum one might be an option to look at. Pulse-Bac has the model 576, 8 gallon steel drum, 176 CFM and 97" lift.

Shop Vac HP ratings are 99% marketing BS. Almost all full size shop vacs have 12A motors, with similar suction. There are some tests done measuring the CFM and static pressure of various shop vacs and dust collection machines, but they are all fairly comparable. Some of the smaller shop vacs, like the little 3 gallon ones, will have a smaller motor, but the full size ones will all have pretty much the same motor. The CFM ratings they list are probably pretty accurate, but there's some BS in those ratings as well. I've always gotten Ridgid brand vacs, and have had good experiences with them. I don't use their stock hose or attachments, they're overpriced and mediocre IMO, I use Cen-Tec hoses.

r/Tools on Reddit: Mid-sized - Wet/ Dry Vaccum - What would you recommend?
March 15, 2024 -

Trying to decide on a decent mid-sized wet/ dry vacuum for the garage mostly and occasional home use. I don't care much about the peak HP, as long as it's got good suction and is durable. Primary use: DIY/ home improvement projects mostly - so think ...drywall dust, sawdust from a sander, miter saw, workshop cleanup, etc. Budget: Ideally 60 -75$

Here are the options I'm considering, what do you guys recommend?

  • CraftsmanCMEVXA18115/ 5 Gal / Stainless Steel / 3 yr limited warranty/ 60$

  • Stanley SL18415-6B / 6 Gal / Stainless Steel /1-year warranty/ 60$

Additional Questions :

  • I'm a bit unsure about the durability of stainless steel, some reviews have mentioned it rusts (which makes no sense tho)

  • Does the 3-year limited warranty with Craftsman make it better than Stanley - 1 year? both these look and work the same from what I observed. ( except Stanley is slightly lower db).

Update: The suction, the steel drum, and durability were my main concerns with what I thought was a fairly good deal otherwise. I'd picked up the Stanley to test it out, but now that's a return. The more I read and talk to people --> I hear good things about Rigid and DeWalt. Also, looks like they do get discounted.. so I can wait.

Hey friends

I'm a homeowner looking into purchasing a wet/dry vac for general handyness/DIY work, amature woodworking, plumbing problems, car cleaning, and just general homeowner business.

I'm looking at a 5 gallon 2 hp shop-vac model for $34 versus a 12 gallon 5 hp workshop model for $55. $55 is my price ceiling on this.

Do you think the 5 gal 2hp model can cut it? Or should I might as well ante up and get the 12 gal 5hp for another $20?

Thanks.

Edit : Looks like both of those deals are dead so now I'm looking at a 9gal 4.5hp ridgid model. I'll think on it for a couple hours but'll probably go this way. Thanks everyone. Stay handy

What size wet/dry vacuum is recommended for a vacbed? I want something that will pull a good vacuum but not so powerful it causes pain or ruptures eardrums. Smaller to be more portable is also helpful.

Unrelated question, the 7 ft side poles are rather awkward to transport. If I chop them in half and use a coupler, am I likely to run into problems?

I don’t know if I am asking too much of a small vacuum, but here is what I would like it to be able to do. I have a bigger one (14 gallon RIDGID) that I find kind of a pain for smaller jobs.

I would like it to be easy to bring up and down stairs. Although capable of wet use, I would mainly use it for DIY clean up. In that regard, can a smaller one hookup to tools (such as jig saw, sander, maybe even a table saw?)? Obviously, I would also use it for car clean out.

I was thinking of something around 5 gallons. Saw good things about a RIDGID and Vacmaster VF408 or the Beast. Thoughts?

Thanks!

Does anyone have a clear explanation for the different performance characteristics when it comes to shop vac hose diameters?

1.25"

1.875"

2.5"

I have a 1.25" hose on one of my Rigid shop vacs that I've been using for years to detail cars. It's been great. But I'm renovating a house so I pulled my second Rigid out of storage and need to buy a new hose for it. I'm just wondering if a different diameter hose might be better suited for different tasks.
