Ridgid’s 16 Gal., 6.5 HP, wet/dry shop vac comes in two flavors: the stainless model WD1956 and the plastic model WD1851. Both models have a 20′ power cord and provide the same power and capacity. They come with the same accessories but the plastic version also includes a rear wind diffuser.
Believe it or not the stainless model is a half pound lighter than the plastic version coming in at only 27.8 lbs without accessories.
Both models have large back wheels making it easy to pull the unit up stairs, but the stainless has taller front casters giving it more ground clearance. This lets the drain plug sit higher allowing more knuckle clearance when draining or hooking up a pump.
After testing both 16 gal. vacs I found the plastic model’s small tool bag useless as it does not hold the accessories securely. Within the large bag of the stainless I’m able to carry the wands, attachments, and other cleaning tools. I also coil up the 20′ cord and throw it in the bag. For me, the extra ground clearance, taller pull handle, and larger bag of the stainless won the day.
Whichever one you get I hope you enjoy it.
