Verdict

The Bosch Professional GAS 35 M AFC is a corded M-class certified wet and dry dust extractor featuring a powerful 1,380 W suction turbine that delivers 254 mbar of vacuum pressure and an airflow rate of 74 l/s. Main characteristics and pros include a 35-liter gross container capacity (23-liter net dry and 19.2-liter net water volumes), a 6,150 cm² flat-pleated filter, an integrated power tool socket with automatic on/off switching, and Automatic Filter Cleaning (AFC) technology that guarantees sustained, powerful suction. However, notable cons include its heavy 12.4 kg weight, a lack of manual suction power adjustments on the unit, and a loud booming noise generated every 15 seconds by the automatic filter tapping process.
