BOSCH VAC090AH Portable 9 Gallon Dust Extractor - HEPA & Auto Clean

Our review of the BOSCH VAC090AH finds it best suited for contractors and serious DIYers who need reliable dust control on jobs involving concrete, tile or wood. The single biggest reason to buy is its combination of an on-board automatic filter cleaning system and a true HEPA filter that keeps suction high while capturing fine particles; in practice that means fewer interruptions and better containment of silica and other hazardous dust during extended work sessions.

Key Features

• Auto filter clean: The built-in cleaning cycle activates every 15 seconds to shake off clogged dust and help maintain consistent suction during long jobs.
• HEPA filtration: The included HEPA filter captures 99.97 percent of particles at 0.3 microns or larger for effective containment of fine dust.
• Strong airflow: Delivers up to 150 CFM so it can handle heavy dust loads from grinders, saws and demo work while preserving performance.
• Power Broker dial: Adjustable suction lets users match airflow to the tool and application, reducing loss of control with light-duty work.
• Tool activation: Power tool activation lets the vacuum switch on and off with the tool for convenient, hands-free operation.
• Fleece filter bag: The included bag protects the HEPA element and provides optimal containment and easy disposal of dry debris.

Who It's For

The VAC090AH is aimed at trade professionals and experienced hobbyists who perform tasks that generate hazardous fine dust, such as concrete cutting, tile removal, or sanding, and who need a portable extractor that helps move toward OSHA silica Table 1 compliance. Its HEPA filtration and reliable auto-cleaning make it a good fit for work sites where uptime and consistent suction are important.

Users who only need occasional light cleanup around the garage or homeowners who rarely generate fine dust may find the capacity and feature set more than they require; likewise, those needing an extractor for wet pickup should look for a model explicitly rated for wet use instead.

Pros & Cons

Pros
