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.

Rated 3 out of 5 by from easy to use but hard to empty the water out Easy to put together would prefer hose storage inside but my one complaint is emptying tank of water it is awkward and can get very messy

Rated 5 out of 5 by from Great size, not too lound This vacuum is not the smallest but it`s just the right size in my opinion. Also the noise is much more tolerable than my ShopVac I replaced. The vacuum tubes seem larger then my Shopvac so compatibility between accessories is not there. Anyway, great vacuum for the price

Rated 4 out of 5 by from RIDGID 4 Gal good suction. Clumsy to carry. Hose difficult to attach. Need some type of handle to pull instead of carrying to work place.

Rated 4 out of 5 by from The unit works well. This unit was purchased to replace a much larger device which was not easily moved around. It is mainly used to vacuum the two cars, and for that it works very well. Plus it is small enough to be portable, but also has strong suction. Since I have only had the vac for a few weeks I can not comment on the durability.

Rated 5 out of 5 by from It has all the power it needs to do a good JOB The only thing missing is an accessory with a brush end, which I feel should come with the unit.

Rated 5 out of 5 by from Great vacuum Used this vacuum to clean my vehicle that was in much need of a clean. Sucked everything up with no problem. It even sucked up all the long dog fur that was stuck in the carpet; just took a little patience to work the fur out. Overall this vacuum has great power for a compact shop vac, plus the storage is a great feature too. All the accessories pack away nicely with the vacuum for tidy storage.

Rated 3 out of 5 by from Has good power. Its lightweight. Nice size The little vacuum has good power and it made clean up easy. I have only used the blower for sawdust. It would get 5 stars but for the hose attachment keeps coming off repeatedly while blowing. It has a cheap plastic hook to attach at the hole and it just won't stay on. i will likely have to duct tape it to stay. So it made working with it harder because i had to bend down often to put the hose back on. Seems to be a design flaw. But you almost had it right, because I like it.

Rated 5 out of 5 by from Great little tool We were in the market for a small wet/dry vac to replace one lost to the flooding after Hurricane Harvey. We were looking at larger units, when this one caught our eye. It's an amazing little tool. It has more power than the units twice its size, and it's really easy to work with. Plus it takes up less space than the larger units. I'm assuming the durability will be as one would expect from Ridgid. I'll update the review if it turns out otherwise. The only reason for the ding on Ease of Use is that winding the cord is a real pain. No more than any of the other units, understand, but an auto, spring-loaded cord rewind would be a great addition.

Rated 5 out of 5 by from Awesome product! Love the Life-Time-Warranty and it was cheaper than the other name brands that have a one year warranty

Rated 2 out of 5 by from Cheap hoses I switched from a shop vac. The rigid has great power and I like the ease of the handle. The hose itself is garbage, bending and kinking easily, with the securement tabs difficult to connect and coming apart easily. I will try it a bit more, but might return and go back to shop vac.
Date published: 2018-08-08
Rated 5 out of 5 by from Haven't had it long, but it works great for a small shop vac The power is much better than the bigger shop vac we're replacing it with. Don't really have a need for higher wet capacity than this one so it's extra nice to no longer have to find a storage place in the garage for the bigger one and its accessories. Plus, can now easily move this new one inside for easy use when doing light construction. Much, much better than the other one.

Rated 5 out of 5 by from 4 gallon wet/dry vac Nice compact wet/vac for the price, performance is very good but just wish it had the bigger 6hp or 6.5hp motor This was a toss up whether buying this or the shop vac with 6.5 hp I purchased this unit because of the warranty.. Also wish Home Depot would carry more accessories for this!!!!

Rated 4 out of 5 by from Small size but very good suction power. Does not tip over easily. No wide floor brush supplied. Stores in small spaces. Strong suction & rolls easy. Does not tip over over easy like other vacs. Strong latches prevent top from pulling apart when lifting unit by it's handle. Dissapointed that Rigid did not have a wide floor brush, but found another brand online for 1 7/8" wand.

Rated 5 out of 5 by from Lifesaver! Our washing machine wasn't draining and it took a toll on our 20 year old wet/dry vac. So after some quick research I decided to purchase this model and I am glad I did. It performed so well that I plan to buy one as a wedding gift for a young couple. The size was great for the job and though I had to empty it a couple of times I was able to carry it and lift to pour out water. Unlike the one we replaced, different brand, this model would indicate that it was full so I didn't overfill. My husband and I agree this size not only meets our needs in performance it also stores well.

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.
