Verdict

The RIDGID 4000RV is a compact, portable professional wet-dry vacuum featuring a 4-gallon rugged polypropylene drum and a powerful 5.0 peak horsepower motor operating on a 120V, 9-amp power supply. Main characteristics include an airflow rate of 92 CFM (43.4 L/s), a 20-foot power cord with integrated handle wrap, an 8-foot ultra-flexible pro-locking hose (1-7/8 inch diameter) with a smooth interior to prevent clogs, a rear blower port, and a toolless Qwik Lock filter fastening system. The main pros are its outstanding suction power for a portable unit, lightweight 14.5-pound design with a comfortable carry handle for high maneuverability, durable motor life, and on-board accessory storage. The primary cons are its limited 4-gallon capacity requiring frequent emptying during heavy liquid cleanups, the lack of a built-in tank drain, and a relatively high operating noise level of up to 70–80 decibels.
