Questions & Answers

How is the dust bag, #VF3501 "C", installed on a RIGID 4 u.s. gallon wet/dry vac?
ByJun 12, 2026

Answer This Question

There is cardboard attached to the bag around the opening, it will slide over the plastic black inlet inside of the vacuum.

By|Jun 17, 2026

    Hello TCombs, Thank you for your inquiry. Here are the steps for you to install the VF3501 filter bag into the vacuum: 1. 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. 2. If necessary, insert the rubber gasket over one side of the split inlet and then the other. This will make getting the inlet into the bag a little easier. 3. Push the cardboard collar all the way forward against the drum, making sure the rubber gasket moves over the single rib that is present on the inlet port. If you have other questions, please call our Customer Service at 1-800-474-3443 from Monday to Friday between 8:00 AM to 5:00 PM Central Time or send us an email at info@ridgidvacs.com and we'll be glad to assist you.

      Hello Jack, Thank you for your question about the RIDGID WD4070 wet/dry vacuum.

            If i were doing the same thing, I would remove the collection bag but, not the air filter. That is just my opinion.

                  The wheel of my WD4070 vacuum just broke. I'm very happy with the product and looking for a way to replace the wheel. One of the small one at the front of the vacuum. Can I buy you one? Thank you!

                  Answer This Question

                  Yes, you can replace the front wheel. The WD4070 uses a replacement Caster Twin Wheel (Part #820002), which is available as a service part from RIDGID. You can check the RIDGID parts website or contact their customer service to order one. Some third-party parts suppliers also carry the same OEM replacement wheel. Good luck with the repair.

                      What size hose is with vacuum diameter

                      1 Answer | 
                      Answer This Question

                      Hi HomeDepot Customer, Thank you for your inquiry and for your interest in our products. The original hose included with the WD4070 has a diameter of 1‑7/8 inches. If you are referring to the end adapter that connects to the suction port of the vacuum, it measures 2‑1/4 inches outside diameter, with an inner diameter of approximately 1.9 inches. We hope this information is helpful. Please let us know if there's anything else we can do to enhance your experience or if you have further questions or concerns, you may call Customer Service at 1-800-474-3443 from Monday to Friday between 8:00 AM to 5:00 PM Central Time or email us at info@ridgidvacs.com.

                          Saved the interior of my car!
                          I recently discovered cars, as a matter of fact, have gutters. I did not know this. Nobody ever told me this, not even my dad. If these are not well cared for, they will get crammed with debris just like the ones on your home. When that happens, this causes water hitting your vehicle to drain into places it shouldn't, like your vehicle interior. My area experienced SIGNIFICANT rainfall a few days ago, and when I hopped in my car after leaving work, I stepped right in a gigantic puddle. I could see water pooling up all around my feet. The entire carpet was soaked, not just in the driver side, but also the passenger side (although far less severely). As I drove around, this water sloshed all over and eventually got to the rear passenger carpets as well. I picked up this particular vac after doing a lot of research. For water extraction from carpet regardless of pile, the gold-standard is a dedicated carpet extractor. These things achieve water lift of over 100 inches, guaranteeing they pull water out from the deepest regions possible. Of course, they are also prohibitively expensive and paying for remediation at a detailer who even performs that work is also quite expensive. Many shopvacs can achieve, at best, around 70-80 inches of water lift and these are on some of the most expensive models you can purchase. This particular vac can only manage about 52 inches of water lift. Not exactly equal to the performance offered from a dedicated carpet extractor, but then again, you really don't need that if you're able to respond to the water as quickly as possible. I specifically wanted a vacuum I could keep in my car, as the large unwieldy ones would be far too massive to lug around when I need to react to a mess as quickly as possible. This little vacuum fits neatly in the trunk of my sedan. The rectangular HD models would also be a nice fit, but they offer marginally less horsepower and water lift (about 10 less inches). I purchased this alongside the auto detailing kit as well, after seeing many professional detailers give it rave reviews. The included attachments are very nice. The detailing hose is far more flexible than the original hose, and the variety of nozzle attachments work very well for working within the confines of a vehicle interior. All-in-all, I was able to suck up a little over 8 GALLONS of water from my car, well before it was able to sit long enough to cause serious issues. I of course have followed up with an air mover for thorough drying, and intend to treat the carpet for mold just to be extra safe. I love this little vacuum and I intend to keep it in every car I may own for the rest of my life.

                              Quality vac. I leave this in the house in a closet for quick access to a powerful vacuum that doesn't take up alot of room. The 5 HP rating is powerful enough to tackle most household jobs. The deal included auto kit which works well for car cleaning (2 dogs). Easy to move around and hide away. Ridgid products always work well.

                              Just received and the hose doesn’t have the lock piece to even attach to vacuum so it’s all useless. Good luck trying to get ahold of someone to fix the issue without returning and re ordering.

                              Thank you for taking the time to share your feedback. We sincerely apologize for the inconvenience you’ve experienced with the hose and for the difficulty in reaching our support team. This is not the experience we want for our customers.

                              To better assist you, we’d like to confirm which hose is missing the locking piece. The WD4070C model typically comes with both a standard hose and an orange hose included in the car cleaning kit, and we want to ensure you have the correct components and provide the best possible solution.

                                The vacuum itself is actually great. Strong suction, works well, no complaints about performance. The problem is the hose connection clip. It broke, and once that clip is gone, the vacuum becomes basically useless. The hose won’t stay in place, air leaks, and suction is lost. I tried to find a replacement clip or adapter — no luck. This small plastic part is not sold separately, which is extremely frustrating. A good vacuum ruined by a cheap plastic clip with no available replacement. Money wasted because of a tiny part.
