Is there a vacuum bag to fit this unit?

I see the filters listed under accessories and know that there is also a bag that fits other Ridgid wet/dry vac models.
Asked by: IM70
There are multiple bags for the various vac sizes. For the WD1851 you're looking for Model# VF3502. This works as a pre-filter to help extend the life of the actual filter. Works great. Don't use it while wet vacuuming.

What is the noise level

Asked by: kurt
It is much quieter than other shop vacs I have used in the past. My ears weren't ringing after vacuuming out the car for an hour and a half.

16 Gal. 6.5-Peak HP Wet Dry Vac is rated 4.7 out of 5 by 638.

The Ridgid 16 gallon 6.5-Peak HP Wet Dry Vac is easy to assemble and is ready to use within 5 minutes of opening the box. The Vac is strong and easy to wheel around even when full. I bought the Vac last December when I saw it was on sale and started using it a few weeks ago. Suction is great and stays strong until full. So far this product has been a better buy than I expected. I've bought it for one job in mind and that is to clean-out all of the sand from a commercial swimming pool filter.

Rated 4 out of 5 by from Nice vacuum. Good power and suction. Parts bag is a little hokey and the wand extension pipes don't stay on the roller base when rolling by the handle tilted back onto the large wheels.

The vac itself works as it should, but the problem we had is the hose falling apart and splitting on all the rib's. The unit is barely 1 year old. The hose is very frail and splits easily. It's in a manufacturing shop so it needs to pick up a variety dirt and debris . Vac was registered and tried to get a replacement under warranty, talked to someone in southeast Asia area, and they said they sent a replacement out and it was signed for but it never showed up to our shop to the best of my knowledge or our S/R people. Now another hose is going bad/splitting so I'll just have to buy 2 replacement hoses because it's not worth the time or hassle to get a warranty hose. The vac itself seems good, but the hoses suck!

Rated 5 out of 5 by from Strong vacuum and quiet compared to competition. Basement flooded and this was on duty working 24/7 sucking water for a week straight out of the crack in my basement floor. Until it burned up because the help let it fill up an continue to run as they watched a movie. Bought another to replace it because it was quieter than the other one. Now I bought one for myself. Great vac.

The hose comes apart while in use sometimes. The fittings are not tight enough and it should lock into place instead of just wand sliding into hose.

Rated 5 out of 5 by from quietly sucks!! This is the quietest shop vac I have ever owned or used. It's also one of the, if not the most powerful shop vacs I've used. I can hold a conversation over it while cleaning the garage and not think twice. As far as the wheel axle caps, they're the same thing that many manufacturers use to hold wheels on, and work quite effectively. Pro tip: Thread the axle, put both wheels on, press both caps on until they stick, lay the vacuum drum on it's side and use a hammer to tap the caps on. Doing so will seat both caps, but turn the vacuum 180 and tap the other cap. Done and done. Takes 30 seconds. I couldn't be happier with this vacuum.

Rated 5 out of 5 by from Great Vacuum This thing will literally, to coin a phrase, "suck the chrome off of a trailer hitch". Great suction, easy to move around, I especially like the latch on the hose that keeps it from being pulled from the vacuum intake as you lead the vacuum around by pulling on the hose, which we all do. I bought it because it had a decibel rating much lower than the next model down. Still pretty loud but for a 6.5 HP motor it isn't bad. I would recommend this vacuum to anyone.

Rated 5 out of 5 by from Amazing! I have delt with many wet/dry vacs being in the Air Force working on jets and in the automotive field as well as the fire department. I most say this is by far the best I've seen yet. I actually became a new home owner and purchased this for my personal use and the first thing I realized right away was how quiet it was! My Dyson vacuum makes more noise. With that being said you would think it didn't have much power behind it and boy was I wrong again. Plenty of power! And very user friendly. Also the filter system is amazing as well, not dust blowing out the back as well as air, your work space is completely undisturbed when it's running.The only thing I don't like about it is the little accessory bag that holds the attachments, it kinda gets in the way and when I push the vacuum it feels like I'm in the grocery store. Other than that , this puppy will not disappoint !
