The RIDGID 50313 (Model 4000RV) is a 4-gallon portable wet/dry vacuum designed for professionals and homeowners who need quick, powerful cleanups without hauling a big shop vac around. With 5.0 Peak HP, it delivers suction and blowing power comparable to units three times its size. The compact body stands just 15 inches high and weighs only 14 pounds, so it tucks into trucks, under workbenches, and on shelves. Everything you need stores on board: the 8-foot locking hose, car nozzle, noise muffler/diffuser, and fine dust filter.
Need a parts diagram for the RIDGID 50313 or a replacement filter for the 4000RV? The Qwik Lock filter system lets you remove and install filters without tools, and the standard bayonet-style hose fits many RIDGID accessories. This page covers the main components you'll want to keep on hand.
This motor gives you the leverage to pull heavy debris and blow out difficult areas. The 4-gallon tank keeps weight down while still handling common jobsite spills and dust.

Because the 4000RV is a popular platform, replacement filters, hoses, and nozzles are widely available. The Qwik Lock clip makes swapping filters a 5-second job.
Everything hangs on the body, so you don't leave the car nozzle in a toolbox. That means less time hunting for attachments.
For wet cleanup, pop off the filter; for dry dust, snap it back. The diffuser reduces exhaust noise in tight spaces.
The included owner’s manual has a parts breakdown. Contact our support team if you need help identifying or ordering a replacement part.
The vacuum uses a fine dust filter with Qwik Lock. Look for RIDGID replacement filters designed for the 4000RV/50313—our team can verify compatibility before purchase.
The hose uses RIDGID’s standard bayonet connection, so most RIDGID wet/dry vac accessories, including extension wands and nozzles, will fit.
Yes. For liquid pickup, remove the fine dust filter so airflow isn't blocked, then dry the tank afterwards.
With its compact size and included car nozzle, it’s a popular choice for quick interior and trunk cleanups.
Picks up well.
It's compact and powerful. I use it for my workshop. Works great.
I bought this vacuum for cleaning up after construction projects. It's got great suction and the wet/dry capability is handy. The filter is easy to change without tools. The accessory storage is convenient, so I don't lose parts. The 4-gallon size is perfect for portability. The only thing is the hose could be longer, but that's minor. Overall, a solid vacuum.
I'm 25 and a renter and this vacuum is great for my apartment. It's small and takes up little space. The suction is really strong. I used it to clean up some water from a leak. It worked perfectly. I love it.
I'm 40 and a homeowner and I use this for garage cleanup. It's powerful and easy to move around. The filter is simple to clean. The cord is a good length. I wish the wheels were a bit bigger, but it's fine. Overall, I'm satisfied.
I'm 72 and this vacuum is easy to use. It's not too heavy. The controls are straightforward. I've used it to clean my workshop for months. It hasn't lost any suction. Very pleased.
It works well, but the hose attachment is a bit stiff. Still, it does the job. I'd recommend it.
I've had this for a month and it's been fantastic. I've cleaned up drywall dust and a flooded basement. It's very versatile. The accessory storage is smart. The filter cleans easily. It's a great little vacuum.
It's decent for small messes. The suction is good, but the hose is short. I had to buy an extension. It's still a good value.
I like that it's small enough to store. The power is surprising for its size. The filter is easy to access. It's a good little shop vac.
I keep this in my truck for spills and messes. It's great for quick cleanups. The on-board storage keeps attachments safe. The suction is strong. I'm glad I bought it.
