Rated 4.6 out of 5 by 254 reviewers.
Rated 5.0 out of 5.0 by Great for Any tradesman. I'm a HVAC technician. I am in and out of customers homes everyday. This is by far the best vacuum that I have purchased to handle the jobs that I do. From its compact size, to its durability and ease of use, this shop vac has stood up to every task I've needed it for. I vacuum out clogged , condensate lines with it. I've used it to vacuum out furnace and ac cabinets with it. I've used it to vacuum out drain pans and overflow pans in attics. It also makes cleaning up after an install a breeze. I've had my Rigid shop vac for about 4 months now, and Its my go to tool for any HVAC maintenance I perform. My customers love it as well. Also, the storage for the cord, hose, and accessories is awesome. November 28, 2014
Rated 4.0 out of 5.0 by The flat top allows for stacking. I had my eye on this vacuum for some time. I really liked the design as my space was relatively small. The hose could reach as far as I needed it to and I could keep my toolbox stored on top of it. Now that I've moved to a larger shop, I would be nice if this was on wheels. I may firgure out a way to do this myself in the very near future. Last great feature is the fact that it accepts the hoses and tools from my last vac. Now I have hoses and attachments in a variety of sizes for a variety of needs. Thanks, RIDGID, for a great vac. November 21, 2014
Rated 5.0 out of 5.0 by if its Ridgid, its a tank! Built really well and delivers enough suction to handle most tasks. Has a little trouble with heavier items (large screws, pulled 16d's, etc). Onboard storage is great, although hose can be kind of cumbersome when in a hurry (gotta get it in just right). I use this vac everyday in my handyman business and it never fails me! A great buy.

Rated 5.0 out of 5.0 by Love this vac! I've wanted this vac for years. A friend bought one a few years ago and I've wanted one since I first used his. I just found it online and got it right away. What's not to love? It is square and flat, so it fits easily I my work truck, stores everything onboard has plenty of power. Perfect!! Love it. Thanks again rigid. November 24, 2014
Rated 5.0 out of 5.0 by this vac is the best portable shop vac I own. This shop vac is the one that goes in my service van, it's shape allows it to stack and ride, it's got plenty of power, and the accesiories pack neatly inside except the extension wands which is the only drawback. The clips that hold the wands should be more secure, wands fall out while riding in the van! November 25, 2014
Rated 4.0 out of 5.0 by This vac is easy to carry and also acts as a step stool I highly recommend this product for those who don't make a big mess on the job but need something powerfull to suck out the dirty when needed. I also like that fact that everything stores into the box and it fits neatly on a shelf November 27, 2014
Rated 5.0 out of 5.0 by great for service vans This is a fantastic thing to put in the service vans. When they job is done, and the customer sees us vacuum up our mess, it makes a fantastic impression. Just make sure the filter is in, and you clean the debris area often, or you will make a HUGE mess. November 25, 2014
Rated 5.0 out of 5.0 by Product is a must have This product is a must have for any shop or garage. It is small and compact so it fits almost anywhere. I was amazed at how quiet it runs and how all of the included attachments fit on the shop vac. Overall I'd recommend this product to every home owner. November 24, 2014
