Rated 5 out of 5 by from All around a great product This vac is powerful and convenient I need it to remove water from my car after a heavy rain event. It remove about 8gallons and sucked the carpet almost dry. I would recommend it especially for its ease of use and very stable resisting fall over while working with it.

Rated 5 out of 5 by from This thing has power, but needs a carpet brush attachment. Ridgid please... make a power brush attachment for carpets. And please... with stainless bearings. Either suction powered or electric without freaking belts. Then will see Dyson, Hover, or Junkie Kong Vac, making wet or dry vac. These Vacs, "5 Peak and up", have plenty of suction power if used correctly. It can unclog a sink, dry a wet floor or pick up normal dust. Yes, they are clumsy and loud, but it is a trade of. They are affordable and versatile.

Rated 5 out of 5 by from It sucks! It sucks up dirt well! Really loud. Louder than most vacuums. It has come in handy on keeping my car clean though!
Date published: 2019-06-02
Rated 4 out of 5 by from Great for condo/apt living I researched virtually every small wet vac on the market and went with this one. Best combination of power, small size and waste capacity. A few deficiencies: Not including a brush is a huge oversight forcing any buyer to purchase a $12 option The hose is poor quality and prone to kinking if not careful. Some easy to use cord storage would be helpful. But still the best option out there.

Rated 5 out of 5 by from Quality product at a good price I recently bought this vac for cleaning out the car and other general garage clean up, including dirt/gravel pick up following winter. So far I am satisfied with the performance and value for money. The suction power is great, as is the ease of use/maintenance. I would recommend.

Rated 1 out of 5 by from Not much suction Inadequate suction when using the attachments. Works decently when just using the hose but it’s not practical.

Rated 5 out of 5 by from Love it! We have 3 dogs that stay inside. We spent lots of money and purchased a Dyson Vacuum (the purple for pets) and it didn't last long at all. We had been using a regular size shop vac but it was just so big pulling around the house. We found this and have been in love ever since. It is light weight and rolls easy. Would highly recommend it!

Rated 4 out of 5 by from Excellent vacuum for cleaning vehicles and other small jobs Great little vacuum. Doesn’t need a lot of space to store. Powerful vacuum from something small. Cons- attachment hoses is too short for cleaning vehicle and you have to buy the car kit which has a longer hose and other attachment to help you get the job done. Expensive kit. Not looking forward to buying it. Might as well find a different vacuum that has the longer hose.

Rated 5 out of 5 by from This little guy sucks Our old shop vac finally died and I was pleasantly surprised how much of an improvement this one was, even with the filter bag installed. We sand a large amount of Bakelite and our old shop vac was not up to the task of collecting all of the fine dust. This little 4 gallon vac was small enough to fit on the bottom shelf of the portable cart we have our stationary sander on. I had been looking at an over-complicated dust collection scheme, but with the price and ease of use, this vacuum was clearly the way to go.

Rated 4 out of 5 by from Solid features and performance in a handy size. I pulled the vacuum from its box, wound out the cord and plugged it in, hooked up the included hose and started sucking up construction debris all within 30 seconds. The suction is plentiful and the unit is easily wheeled — or carried — around. It's light weight but fully able to handle the dirt, drywall, busted concrete, carpet fuzz, and wood chips that littered the bedroom floor and patio. My wife asked if she could use it as a blower, so I connected the hose to the exhaust port and she whizzed all around the patio banishing dirt and gravel and dog hair and dead leaves. The only hiccup was, towing the unit from the exhaust port, instead of the input port, doesn't allow the castering wheels to function properly and the unit, thus, pulls a bit awkwardly from a corner, which causes the large wheels to be dragged rather than rolling. No biggie, but the hose kept popping off the port, despite the included latching features. (She added some tape to keep the unit and the hose together.)

Rated 4 out of 5 by from I just used it twice , so far so good except the hose Im love ridgid vacuums and this is my third one for when o do small drywall jobs in houses while ppl are in. So far so good except the hose. All the hoses are hard to move and not flexible at all i wish ridgid will start making better flexible durable hoses. All ridgid hoses bend and dont flex which decreases the beauty of those excellent vacuums.

Rated 5 out of 5 by from Great Vac This is a great vac for cleaning up my car. I couldn't be happier. The compact body and versatility of the tools make this a must have for someone that really likes to get into all the tight place of your auto. Under the seat, in the nooks, and trunk are all a breeze with this little workhorse. Thanks Ridged for making a great heavy duty product and thanks Home Depot for great prices and shipping right to my doorstep! Very happy with my purchase.

Rated 5 out of 5 by from Small but Mighty I needed a compact vac that still had the power to handle normal clean-ups. I also needed one that didn't sound like a jet taking off! This unit can fit in the trunk of my wife's car, is quieter than any other vac I've owned, and has the power to handle the projects that I need to clean. It is a great value.

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.

How do you put the vaccum bag on?

My vaccum has a part on the inside that the instructions on the vaccum bag does not show nor does the owners manual show it or mention anything about the bag and how to use it,
Asked by: Angie
Hello Angie, To install the filter bag, push the cardboard cap into the bag before trying to install onto the inlet. This will punch a hole in the paper, and make inserting the bag over the inlet easier. If necessary, insert the rubber gasket over the flange on the inlet tube. Push the cardboard collar all the way forward making sure the rubber gasket moves over the single rib that is present on the inlet port. If you have any further questions or concerns, you may call us at 1-800-474-3443. Thank you, RIDGID Customer Support

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.
