This product ranks #1 of 8 in Car Air Dryer.
Last reviewed June 8, 2026
TL;DR The Revolution runs the same twin-motor steel-canister platform as the MB-3CD · community-confirmed (AutogeekOnline) for reliable full exterior clearance in roughly 10 minutes. The 30-foot hose is the differentiator: one canister placement covers a full-size SUV without repositioning. Unheated. Metropolitan Vacuum Cleaner Co. holds UL file E31177 covering blower cleaners (UL Product iQ, verified May 2026).
A motor-unit + 30-ft flex-hose car dryer: 17-lb steel canister on swivel wheels, twin 4.0 peak HP universal motors, 120V corded, two-speed. Manufacturer claims 227 CFM at the motor (metrovac.com) · friction in the 30-ft hose reduces effective nozzle-tip output; no independent nozzle-tip measurement available. Unheated · ambient air only. Five attachments ship in the box: Crevice Tool (narrow concentrator), Air Flare cone, Inflator Adapter, Hose/Air Stream Adapter, and 1½-inch Neoprene Blower Nozzle. Platform noise is 74·82 dB depending on speed; community rates it loud but outdoor-tolerable.
The right tool for a weekly home detailer washing full-size SUVs or trucks who wants to eliminate towel contact and cover the whole vehicle without repositioning the motor. Skip it if you already own an MB-3CD · the 30-foot hose is the only meaningful upgrade. Skip it if you need heated air · this is ambient-temperature only.
UL Listed under file E31177 (Metropolitan Vacuum Cleaner Co., Inc.); no Intertek ETL listing found. No CPSC recall on file as of May 2026. Corded mains-powered · no battery disposal concern. Dispose via standard US e-waste drop-off at end of life. No chemical SDS applies.
Metropolitan Vacuum Cleaner Co., Inc. · the manufacturer of MetroVac products · holds UL file E31177 covering vacuum cleaning machines and blower cleaners. A UL Product iQ search on May 17, 2026 confirmed this file at the manufacturer-org level. The per-SKU line-item mapping inside E31177 was not separately exposed in the public search, so the safety_certification score is 8 (file-level confirmation) rather than 9. No separate Intertek ETL listing was found.
The Revolution (MB-3CDSWB-30) adds a 30-foot flex hose and front swivel wheels to the same twin-motor steel-canister platform as the MB-3CD. The 30-foot hose lets you position the canister once per side and reach all panels on a full-size SUV or truck without moving the unit. The fixed-wheel MB-3CD ships with a shorter hose and is positioned primarily as a detailing blower for crevice and emblem work. The motors, nozzle kit, and 5-year warranty are identical.
As of May 17, 2026, the bundle ASIN (B07MZFJFJZ · the Revolution with 3 extra filters and 16 oz MetroVac Car Shampoo) shows as currently unavailable on Amazon. The base 30-foot hose variant (B00UVUTP2S) and the standard swivel-wheel model (B00UMD7TGS) are the available alternatives on the same motor platform.
MetroVac publishes 74 dB at the 4HP setting and 82 dB at the 8HP setting. Community data from the MB-3CD sibling platform (identical motors) describes the unit as loud but manageable outdoors. No independent measurement at or above 85 dB has been documented for this platform. Hearing protection is a reasonable precaution for extended indoor sessions.
