Rated 4 out of 5 by from vacuum works great I sold it because it did not come with wheels. would be better if it had wheels.

Rated 4 out of 5 by from compact This is a nice compact shop vac. The reason for only 4 stars is I don't know how long it will last. Hopefully like the last one.

Rated 5 out of 5 by from Nice and portable with plenty of suction power It should come with a bristle brush and a crevice attachment for doing the car.

Rated 4 out of 5 by from Great portable vacuum Easy to set-up out of the box, light and portable. Using it for wooding working (miter saw and portable sander) does a great job in keeping dust to a minimum so far. Vacuum bags are going to make clean-up even easier.

Rated 4 out of 5 by from Would be nice to have wheels. Powerful and have a nice long cord Like the power but really a bag is needed. The filter gets plugged fast but a bag would sure help. The cord is nice and long which is great. Got tons of suction. Good small compact vacuum for small jobs like drywall fixes and general reno clean up.

Rated 5 out of 5 by from Very powerful in small package If you need a powerful vacuum in a very light weight portable size, this is the vacuum for you. And from the trusted and durable RIDGED brand.

Rated 5 out of 5 by from Compact with very good suction. The 5hp motor generates very good suction flow at the hose end. Use it to vacuum a pellet stove and to suction saw dust from table saw. Both jobs done very effectively now.

Rated 5 out of 5 by from Best wet/dry vac ever used! We love the Ridgid 4 gallon wet/dry vac. It’s one powerful little sucker, it could suck the spots off a Dalmatian! Great for quick clean up whether it’s dog hair or spilled cereal, super quick & convenient. If they made a better way to store the hose on vacuum it would be perfect.

Rated 4 out of 5 by from Decent Price for solid vac Nice package and good design. I bought it due to owning the much larger one from Rigid and have had that one for years. i expected a little more suction power from Rigid... and Rigid could have made the storage area more functional for adding additional accessories that were not included.

Rated 5 out of 5 by from May have restored my sanity A little while ago, I had a bedbug scare in my room. After doing some research, I decided to put down some diatomaceous earth in my room for some easy, inexpensive protection. For those who don't know, DE is a very fine powdery substance and a desiccant which turns out to be a lethal combination for most household vacuums. I'm a real neat freak, so not being able to safely vacuum in my room was very stressful as I scrambled to sweep and scrub away the excess DE that formed a perpetual layer of stinky dust on my stuff. After getting fed up with this inefficient work, I finally decided to spring for a wet-dry vac that could handle fine dust. I first looked at Shop-Vac stuff since they're the most popular, but honestly their product lineup was too confusing, had a lot of poor reviews and their website doesn't even work right. I eventually decided on this model instead because it's not too bulky and it comes with the fine dust filter I needed, which made for a very attractive price. It's perfect. I've gone over my room with it only once and it didn't seem to spit out any dust, my floor is the cleanest it's been in ages and I can already see a reduction in the dust element in here. Thank you so much Ridgid, I don't normally review things like this but the peace of mind you've given me is well worth the time.

Rated 4 out of 5 by from Would buy again It's pretty powerful for its size. I use it for a homemade dust collection system using 2" pvc pipes. It works great. My only complaint is that it's pretty loud. I put it in another room and drilled a hole in the wall to run the hose through and then used an automatic turn on/off switch for outlet when the tool is being used. It has good power and would buy again. I have only used it a couple of months at the time of this review.

Rated 5 out of 5 by from Good design and powerful motor I love that it stacks in my truck like a toolbox. The only thing I have a problem with is the accessory tubes clip to the side and those holders fall off alot
Date published: 2019-01-05
Rated 5 out of 5 by from Gets dust and debris off the floor easier and better than sweeping! I have a smaller, less power vacuum but opted to buy this one to get the higher HP motor, and the extension wand that come with it are wonderful, as is the diameter of the hose - less prone to clogs.

Rated 5 out of 5 by from Seems great, just got it. So far I love it, only got it for Christmas. Wasn’t able to buy extra filters at The Home Depot near me.

Rated 5 out of 5 by from Nearly perfect Right out of the box, it's a breeze to use. I purchased the deluxe car detailing kit for the upgraded hose, and I now understand why. The included hose is alright, but essentially one piece of molded plastic. I use it to blow grass off of my walkway after lawn work. I use the deluxe hose for everything else. Great suction, solid amount of attachments out of the box, but I DO recommend biting the money bullet and getting the car kit alongside this. You wont need anything else. I use this Vac for cleaning the nightmare of cereal from my car every week. Two little girls definitely warrant purchasing a powerful product like this one! Our house vacuum couldn't cut it. :)

Rated 5 out of 5 by from I am a nearly 70 year old woman who needed a shop vac. managing the big ones was more than overwhelming , this size is just right for me. easy to put together and strong vacuum easy to maneauver as well.

Rated 4 out of 5 by from Its a Vacuum- IT SUCKS- We just purchased the vacuum. Used mostly in pet areas. So cleaning up litter and dirt does a great job. Its lightweight and is to move around use.The caddy tray is useful. We were using a 16 gallon, just to heavy to maneuver. With the heppa style dust filter helps keep dust done.

Rated 5 out of 5 by from Extremely powerfull suction but needs two speed switch. Extremely powerful suction, right reasonably low weight and bulk for apartment or home dweller. Could benefit however from two speed switch for furniture or light upholstery.
Date published: 2018-12-27
Rated 4 out of 5 by from Very powerful motor but hose attachment to body is a bit challenging Pros: -super powerful suction -weight is nice and light. -nice wand attachments (get 3 of them) -easy to clean -small and portable Cons: -loud (I guess normal for shop vacs) -build quality of hose is questionable -attachment of the hose to the body is a little challenging to put on and take off and I'm not sure how long it will last as the hose is locked in place by a plastic latch

Rated 4 out of 5 by from this is not a 4 gallon portable wet/dry vac - it is a brushless 18V Wet/Dry Vacuum. Does not have a category on website to register this unit. picks up well - purchased it to vacuum dust out of saw controls in a dusty location of fabrication shop.

Rated 5 out of 5 by from Powerful for it's size! I just bought this and am very happy with it. I mainly got it for cleaning the cars out and cleaning up spills around the house. I have used it a couple of times and was very surprised with how powerful it was. I cleaned up a spill on the carpet and it was so powerful that it lifted the carpet away from the pad and was done in just a couple of minutes. I couldn't ask for more. The only reason I only gave it a 4 for durability is that I have only had it a few days so don't really know but the Ridgid name and warranty makes me confident it will be fine. I highly recommend this if you need a great small wet dry vac!

can I buy a foam filter for a Model WD4070

I use this vacuum to clean up liquid spills, I would like some kind of filter as opposed to running without
Asked by: filterrequest
The filter and the way it mounts on to the vacuum is exactly the same as many other brands. So though I have not done so myself. I am pretty sure there is a foam filter out there under another brand that will fit.

Does teh VT2570 hose kit work with this model?

It says it fits a 1 7/8 hose. The adapters do not connect the attachments. Please assist.

If a airwatts are 0.117354 * (CFM) * (inches water), then do I calculate correctly that this model no. WD4070 will lift water 12.9 inches high? 167 watts * (1/0.117354) * (1/110 CFM) = 12.9 inches water I feel like that number is way too low - I'm sure your product lifts water more than 1 foot high! I may have the calculation wrong or the pressure may be specified another way. What do the units of "G/h" mean? Thank you for the help.
Asked by: Jacob
You are over complicating the purchase of a vacuum. This is a small vacuum that is very powerful. Its not intended for professional use but will hand any job you have to do around the house. I know it has served me very well.

Can you get wheels for a rigid WD4050

Asked by: beresford5
It comes with wheels. If you mean replacement parts, go to Ridgid's web site.

Is the storage bin avaliable separately for sale? My unit fell and the wheel stud broke off..

What to do about the air blowing out the back?

Three questions! I have been using this unit for a year and I have almost no complaints. (1) The air blowing out the back is bothering me. When I had a regular vacuum cleaner (and smaller) the air blowing out the back of the vacuum was not noticeable, i.e. the unit was not as powerful as this one. Since my home is hardwood floors it is pretty obvious to see the effect of this blowing air on the opposite side of the direction I am cleaning in -- it makes the a lot of dust and particles airborne. I have asthma, so when I say bothering me, I mean I am sneezing and coughing after cleaning. Any suggestions? (2) Just to confirm, the dust bags are used for larger debris, e.g. sawdust, but the regular filter is for standard vacuuming? (3) What are the application of using HEPA filter for this vacuum? I was considering getting one for the above mentioned reason (re: I am an asthmatic). Thanks!
Asked by: Alexa
Hello Alexa, Thanks for sending your questions! First, we're sorry to hear your difficulty with the blowing air coming out of the exhaust port of the vac. The WD4070 is powerful with a 5.0 peak horsepower and 110 suction power in cubic feet per minute (CFM). Note that the amount of air entering the suction port is the same amount of air blowing out of the exhaust. Unfortunately we can't stop the air from blowing as your vac has a blowing feature where you can connect the hose into the exhaust if you intend to use it for blowing leaves and other debris. Having said that, you can buy a muffler diffuser VT2525 at Home Depot stores or online at This accessory will control the strong pressure of air blowing out of the exhaust port. On a different note, we have different filters for different applications. The supplied blue 3-layer filter is ideal for fine dust such as drywall dust or cement dust. We also have a standard filter VF3400 for typical basement or garage dirt. The dust bags can be used for either small or large debris in conjunction with the cartridge filter. Lastly, the VF3600 HEPA media filter can be used for pollens or allergens. If you are asthmatic, we suggest that you use the VF3600 filter plus the VF3501 dust bag. If you have more questions, please call us at 1-800-474-3443.

vacuum bag

If I am using a vacuum bag should I still use the circular clip on filter as well?
Asked by: piranhajon
Hello piranhajon, Yes, you still need to use the filter if you are using a filter bag with this vac.
