Rated 4.7 out of 5 by 335 reviewers.
Rated 5 out of 5 by Compact and very powerful! I bought this vac to replace and old craftsman 2 gallon vac and am very pleased with it. It has exceptional power for its size and I like the fact that it's very portable. Not sure on its durability, but so far so good. April 26, 2016
Rated 5 out of 5 by sturdy,great suction Great vac, excellent suction, doesn't blow dust into the room when you turn it on April 21, 2016
Rated 4 out of 5 by Impressive Power For Size I already have the 16-Gal Ridgid shop vac, that thing is a monster. I wanted something smaller to using with the dust port on my power tools. I use it with the disposable dust bag since I do mostly sanding. I does reduce the suction a little, but saves on the pricier filters. I bought this one because of the power-to-size ratio. The build quality is average, nothing to write home about. In the end, you get what you pay for and to compare it to a Festool MINI dust extractor would be unfair. It works well, I'm pleased with it and would buy it again if I had to. Too early to comment on its durability. April 21, 2016
Rated 5 out of 5 by it sucks been using this type of vac for over 10 years, use it everyday at work. need to bring back the old model with no wheels.the wheels just makes it harder to carry. will not hold 4 gallons of water. April 21, 2016
Rated 5 out of 5 by Rugged Riggid We have had this a few months, It is our second vacuum of this same type. My husband was on his way to the job and he forgot to shut the tailgate on the truck, well the Rigid was in the truck and it fell out on to the highway. Luckily I came after him and saw it in the road, I told my son that there's something in the road and I realized it was a vacuum, then its our vacuum. O boy, we had only had it a few days and I thought for sure it would be ruined, He had to be going at least 40- 45 when it fell out and hit the road. Well a few bumps and bruises to the Rigid and it works like new, we think it should be renamed the rugged Rigid, Ha ! Ha. the Payne Family April 17, 2016
Rated 5 out of 5 by A powerhouse! We immediately put our 4 Gallon Wet / Dry Vac to rugged use in the cleaning of our kitchen remodel. It ate everything, from dust to large chunks of mortar and concrete, and it also took care of leaking water as well. And it continues to perform like it did right out of the box. The clincher at purchase was the 5 hp motor. This vac is worth every penny. Great unit! April 14, 2016
Rated 4 out of 5 by Excellent suction and will pick-up most anything. I looked for a new machine after my old Shop-vac bit the dust, literally. I really liked the features and size of this machine. The 1 drawback I see is the hose itself, I would like it just maybe another foot longer for doing shelves or areas shoulder high or so. If you use the extensions your moved back and away from your area that needs cleaned, but overall I really like this new machine. April 10, 2016
Rated 4 out of 5 by Compact and easy to use. Good suction. Should come with filter for wet vacuuming. Hose could be more resilient. Compact size with power of large wet/dry vac is a big plus and my main reason for purchase. April 9, 2016

Answer: 
Here are some notes from the manual:
Vacuuming Liquids:
1. When picking up small amounts of liquid the filter may be left in place,
2. When picking up large amounts of liquid we recommend that the filter be removed. If the filter is not removed it will become saturated and misting may appear in the exhaust.
Warning: do not remove the filter cage and float. The float prevents liquid from entering the impeller and damaging the motor. The cage prevents fingers from touching the impeller.
3. When the liquid in the drum reaches a predetermined level, the float mechanism will rise automatically to cut off airflow. You will know that the float has risen because vac airflow ceases and the motor noise will become higher in pitch, due to increased motor speed. When this happens, turn off the vac unplug the power cord, and empty the drum.
4. After using the vac to pick up liquids, the filter must be dried to avoid possible mildew and damage to the filter.

Thank you

Answer: 
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.

Answer: 
Thank you for your interest in RIDGID!

It is encourage using a wet rug and wiping the dust accumulated on the vacuum’s power head rather than washing it directly with water as the water might enter to the motor which will be a safety issue.

Answer: 
Yes, I located one at Home Depot; although the one I found that would fit a 1=7/8 inch hose was available only with a 'crevice nozzle' attachment as well. It seems the price for the two attachments was about $14.00 and some change.
