Rated 5 out of 5 by from nice well rounded unit Had a older model that I liked. Updated to this newer unit and works great only thing I would change is a bigger accessory bag.

Rated 4 out of 5 by from Great suction and quiet, hose needs upgrade. I think this vac out performs similar brands I've owned in the past, but I'm not satisfied with the hose quality or how it connects to the vac. Ridgid offers a better hose (as an optional accessory), why not make it the standard? The connection method could be a better design as well.

Rated 4 out of 5 by from awesoms suction, rolls easily, love the cart to hold the accessories works wonderfully, love the suction power. Easy to clean out debris. only thing that I don't like is that the extension tubes don't stay on at times. The tubes fall off when they are put on together.

I have the WD16650 model and want to know if a filter bag is made for it?

Asked by: Bakodude
I've got 16 Gallon Model # 1851 and it takes Vac Bag VF3502 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.

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.
