Rated 5 out of 5 by from Well made This vacuum is built well, pulls around easily with hose, and has plenty of suction. Overall, I like it better than by former shopvac of the same size, except it is not set up as well as for bags in the canister.

Rated 5 out of 5 by from 16 Gallon Wet/Dry Vac With Cart The best t. Moving this cart from one area to another is so easy with the wheels. Example: When moving it from one side of a 40 foot long garage to the other side, I can push it instead of lifting it or trying to roll it which is much easier on your back. The suction is great. In fact, I like this one so much, I bought one for myh son for Christmas!

Rated 5 out of 5 by from Easy to use and store away. Picks up leaves on my patio with ease. RECOMMENDATIONS: 1] The filter should be like it used to be with a wing screw to remove the filter. Using the rubber push with a thumb is rather difficult. 2} The parts bag on the handle bar needs to be deeper. 3] The top of the wheels are missing the crevice position to store the rigid hose. 4] The cord storage area above the motor needs to be deeper and with bigger ears to allow ease of cord storage. 5] All wheels should be big to allow ease of pushing and moving around.

Rated 5 out of 5 by from Exactly What I Needed When a contractor bails out the weekend before Thanksgiving, leaving a horrible mess of dust and debris, it's time to take action. I purchased my unit at the Home Depot nearest my home and went to work. It was, indeed, exactly what I needed. It's quiet, dust free and has powerful suction, allowing me to clean debris from every surface, including the furnace ducts. The cart made it easy to maneuver around the house and the tool bag kept the accessories close at hand. I would definitely recommend this product!

Rated 5 out of 5 by from this vacuum really sucks literally this vacuum has great suction. best vacuum ive ever owned. love the noise level as well. its quieter than my 5 gal 2hp vac.

Rated 5 out of 5 by from 6.5 definitely has more power than the 6 hp. The additional power is a nice feature, and a little big quieter. Convenient to have storage for accessories, and with a little more thoughtfulness, a really good solution could be found (better than hanging bag). I have several Rigid Vacs and seems to make sense to buy a new unit rather than replace filter and other parts, when a little more will purchase a new Rigid Vac.

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.

Answer: 
According to our Product Manager, You need to first think of CFM and Inches of water lift in inches as two different and inversely related measurements. To maximize CFM, you need a wide open path with as little resistance as possible to move as much air as possible. To maximize inches of lift (or better recognize or measure) that flow of air needs to be restricted, or blocked. So to assume that our machines generate 203 CFM and 49 inches of lift at the same time is a miss-conception. The calculation you completed was “at 306 air watts and 203 CFM, what are the inches of lift being produced”… and the answer is 12.8. Essentially, you’ve identified the inches of lift at the rated max CFM and Air Watts. For example, if you solved for CFM at max inches (say 49) you get a really small CFM number, somewhere below .2 CFM. This is because at max inches (the hose is blocked) and there is “no” air moving through the hose.

We hope this helps. Have a good week ahead!

Thank you

Answer: 
Thank you, RIDGID! That really helped me understand how the pressure and CFM are related, and the calculation result of 12.8 inches makes sense now. I didn't realize the airwatts equation was NOT referring to "sealed" inches of water. Now I see why using sealed inches for calculating airwatts wouldn't make any sense.

You mentioned 49 inches a couple times. Is that the sealed lift this vacuum is rated for? If not, would you please share the max water lift rating?

Thank you again.

I think they are usable on both models, but you'd still need to double check. Maybe Home Depots site or just call or email Rigid.

Answer: 
Thank you for your interest in RIDGID!

Please confirm the exact model of your vac. The WD16650 model is not designed to hold a filter bag. But the product above is the model number WD1851 which is designed to accommodate a filter bag. If your vac is WD1851, the part number of the filter bag is VF3502.

If you have any further questions or concerns, feel free to call us at 1-800-4-RIDGID (1-800- 474-3443) or you may send your email to [email protected]
