Rated 4.7 out of 5 by 245 reviewers.
Rated 5.0 out of 5.0 by Very Powerful Shop Vac - Reliable Had good ratings so that's what influenced my purchase. So far it, has lived up to its excellent rating. As long as you change the filter and remove the debris from the tank, I feel this shop vac will last a long time. My husband leaves it in the garage because it's a little heavy to carry from the basement. I believe it's better than a Craftsman product. November 25, 2014
Rated 5.0 out of 5.0 by Takes a licking and keeps on ticking even with my wife using it! I have had this wet/dry vac for quite a few years now expecting at some point for it to simply wear out as did the last wet/dry vac I purchased, but it just keeps on going strong even with my wife using it occasionally! She usually breaks any tool she uses so that is saying something! November 25, 2014
Rated 5.0 out of 5.0 by This is a real workhorse The only negative is that my old one had a filter efficiency indicator feature which I liked. The warranty is fantastic and so is the company. They gave a free replacement after more than 10 years of heavy use because the bearing was shot. I will never buy another brand. November 26, 2014
Rated 5.0 out of 5.0 by Great suction As a locksmith I have lots of brass pins on the floor of my service vehicle. The Ridgid vac has no problem picking them up whereas my previous vac would not! Congratulations to Ridgid for a vacuum with great airflow volume and suction. November 25, 2014
Rated 5.0 out of 5.0 by Very versatile - it has not let me down yet. So far so good. It has cleaned the car, the truck, the bathroom floor at my mother-in laws. It sucks up dog hair, saw dust, leaves on the walkways and spider webs in the garage. Ive had the unit for almost two years - works great! November 24, 2014
Rated 5.0 out of 5.0 by one tough vac Bought this vac to do all kinds of cleaning jobs , in the garage, in the yard, around a fountain. In the wet mode this vac does not hesitate to quickly and effectively pick up all the debris as well as the liquid. Can't be beat November 24, 2014
Rated 5.0 out of 5.0 Rugged and High Capacity The 16 gallon wet/dry vac with cart is rugged and can take a beating. The 16 gallon volume is great since it allows a lot of vacuuming between stops to empty the canister. Well designed and well made. November 24, 2014
Rated 5.0 out of 5.0 by King of work vacs! This is by far tougher then any shop-vac I've ever used, power is just awesome! Warranty amazing! This baby can suck up water all day long and beg for more. Ridgid vacs are the way to go. November 24, 2014
