Rated 5 out of 5 by from Perfect size. I bought this because I wanted a smaller vacuum than my large shop vacuum (not Ridgid), which is a bugger to move around. It fits my needs perfectly and is easy to use. It is a little noisier than I expected, but not objectionable for my needs. I marked durability as 5-star, even though I haven't had it long enough to know. I did so, because of the warranty.

Rated 3 out of 5 by from Weaker than others I have owned I bought this one for it's compact size. However it is weak compared the Sears Craftsman wet dry vacs, and I'm not a fan of Craftsman. However they do have a strong vacuum.

Rated 5 out of 5 by from 4 gal portable wet/dry vac This is the 2nd Ridgid 4 gallon vac I have bought. It works great on the job site for small debrie. I would recommend buying the muffler to help keep the sound down if you are using this item on a residential job site. Buy with confidence.

Rated 4 out of 5 by from Powerful vacuum in a portable size Positives: 1. Great suction - used it to cleanup construction dust. 2. Wheels and long cord made it convenient to work a large area 3. included 2x24" rigid pipe sections and a floor vacuum head so I could vacuum the floor without bending over. 4. Excellent dust filter - no drywall dust came out the exhaust. Improvements suggestions: 1. include a 90 degree pipe to redirect exhaust up and away from the floor. As I was cleaning one section the unit would swivel on its wheels and often the exhaust port would be directed at a still-dusty area... resulting in a new dust cloud. 2. Quieter would be better 3. Better and wider floor vacuum head - the one supplied would not pick up dust unless it was at a perfect angle to the floor and would not pick up water easily.

Rated 5 out of 5 by from Vacuum with suction! This is the second 4-gallon Ridgid vacuum cleaner we have bought. I needed a vacuum with plenty of suction to clean floors, etc. inside. The other one is being used in the garage. We have used that one for years without a bag, and it still works perfectly. I am using a bag with this new vacuum, and it still has incredible suction. Highly recommend!

Rated 4 out of 5 by from Excellent suction power, long power cord, lightweight, but rigid hose. I would have given this product 5 stars, but I have one complaint. The hose is rigid and hard to maneuver on stairways. I am hoping it loosens up with use and doesn't crack. Wish there was a better quality, more flexible hose on this shop vac.

Rated 5 out of 5 by from small but powerful Lots of power and very easy to move around the shop. I think it should have come with a brush attachment and a diffuser I haven't owned it long enough to comment on durability I rated it in order to complete the review. This is my second Ridgid vac. If my new one is as durable as my first, it deserves 5 stars.

Rated 5 out of 5 by from the hose is stiff The hose is stiff and you store it on top and it is cumbersome and makes it difficult to store in the garage. Otherwise the vacuum is surprisingly powerful.

Rated 5 out of 5 by from Great design Just bought the 4 gal and it does everything I wanted it to. Compact and flexible enough to use in my small workshop. Quieter than others I've used, it's powerful enough to clean up quickly and suck down a vinyl glove by mistake. (Also easy to remove before clogging the filter.) Can't speak to durability after only a week, but it looks well-built and should last with proper care.

Rated 4 out of 5 by from Good vacuum. The only thing negative about this vacuum is the oval shape. When using the bag, everything bunches at the inlet of the vacuum/bag. You have to open the lid, remove the bag and shake it to move contents to the end of the bag.

Rated 4 out of 5 by from Rigid 4 Gal Wet/Dry Vacuum I've only had the vacuum for a month or so, I bought to replace a Shop Vac that burned out in less than 2 years. So far, it seems very powerful and easy to use but I haven't sucked up a lot of dust or drywall dust which is the real test. I'm using it on a home flooring project and it does a great job. Time will tell how well it holds up, but I like that Rigid offers a lifetime warranty if you register a product, and I've collected on several items from Rigid that I purchased from Home Depot and have never had a problem with them not honoring the warranty.

Rated 5 out of 5 by from Great size and high performance I replaced an old 12 gallon Craftsman vac with this 4 gallon RIGID. The size is perfect for jobs around the house and as a car vac well. The size and weight makes it very easy to use and store. I also purchased the car vac accessory kit which is also exceptional both in performance and value.

Rated 4 out of 5 by from Good for the price Not a bad little vac. I purchased it to use as a multi use one for the shop, house, and cars. So far the house and cars have put it through the wringer. It does not vacuum up fine dst as well as I was hoping, but for the other uses it has been great so far!

Rated 5 out of 5 by from Great value for the money This little vac is very powerful for it's size and is easy to maneuver around. It is great for the shop or garage. I like the way the hoses fasten together and cannot pull apart accidentally.

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.

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.
