Rated 5 out of 5 by from 16 gallon vacuum It was time for a new shop vacuum, did plenty of research on them, the price,the performance,the warranty is outstanding. Unboxed unit and assembled, moving it around is so easy and the storage pouch is big plus holding all the attachments. The electrical cord is very long, the suction is phenomenal. I am very happy with this vacuum.

Rated 5 out of 5 by from Powerful Purchased this unit to use on wood working tools because it had a very high CFM rating - completely satisfied with its performance.

Rated 4 out of 5 by from Decent vac. Decent vac for the money, on sale at the HD for $99. Accessories bag is somewhat lame but actually beats the old style plastic hanger that constantly fell off. The hose extension tubes hook onto the base well but if they would attach at the opposite direction the hose could connect during storage. Secure hose storage is, as always, a problem keeping it wound and in place. The power cord wraparound handle combination is to small to accommodate the good length cord. It is quiet and has good suction. Overall good vac that need some design changes.

Rated 5 out of 5 by from Excellent suction, well made, easy to maneuver 16 Gallon, 6.5 HP wet/Dry vacuum, with handle/storage bag. Excellent performance, easy to move up and down steps. I also purchased the defusier and soft dusting nozzle. Well made product. 1 minor issue, 1 of the plastic pipe extensions is a bit tight to attach.

Rated 5 out of 5 by from Great little shop vac Dead simple to use, rolls easily and when empty light and easy to carry. Sucks water like crazy, tough durable seeming plastic, top pops off and on in a snap. Used it to suck hundreds of gallons off my pool cover and it works like a champ.

Rated 5 out of 5 by from Very good product this is the 3 one which I have owned. This is very good product have 3 of them and work them steady. The only thing which is not good when the motor wears out you cannot get replacement brushes. You will have to hunt around for them and adjust the brushes you find to fit.

Rated 2 out of 5 by from Big wheel fell off The cheap bang on clamps for the wheels are a pitiful design. I did what Ridgid should have done and drilled some holes through both ends of the wheel axle to secure the wheels with cotter pins. Also the extension pipes fall out at will so I've bought some bungees to strap those down. Lazy work Ridgid, really.

Rated 5 out of 5 by from This will last till I die. Got this a few weeks ago. We built a 3 car detached garage about 200 feet from our house to use as car storage and work shop. The large easy to use wheels are a blessing. Love the tool storage bag for us older people who can’t always bend down. Very powerful suction. Came with the blue filter which better catch’s saw dust and drywall dust. Ridgid you make my life easier, so thank you for that.

Pressure

If a airwatts are 0.117354 * (CFM) * (inches water), then do I calculate correctly that this model no. WD1851 will lift water 12.8 inches high? 306 watts * (1/0.117354) * (1/203 CFM) = 12.8 inches of water I feel like that number is way too low - I'm sure your product lifts water more than 1 foot high! I may have the calculation wrong or the pressure may be specified another way. What do the units of "G/h" mean? Besides, it seems like an odd coincidence that this is almost exactly the inches for model WD4070 when the WD4070 is rated 5.0 peak HP and the model on this page is rated 6.5 peak HP. Thank you for the help.
Asked by: Jacob
You are right it would lift water more like 10 ft.

Why am I losing suction on my 16 gallon wet/dry vac?

After running for a short period, I lose all suction and no air is blowing out the exhaust. I've cleaned the filter thoroughly and removed all debris inside the vacuum. I also make sure the rubber gasket on the filter is secure around the base of the filter cage. It sounds like the float goes up right before the suction is lost and then drops when the vacuum is turned off. Any suggestions?
Asked by: LarryA
The vac has to remain upright. Check your filter, is it clean or packed with dirt or wet? If so replace it. Also if you are vacuuming liquid, you have to use the correct filter for that. Hope this helps.
