Verdict

The Bosch Professional GAS 12-25 PL is a corded electric, certified L-class wet-dry dust extractor featuring a powerful 1,250 W motor that delivers a maximum turbine airflow rate of 65 l/s and a vacuum pressure of 200 mbar. Its main characteristics include a 25 L gross container capacity (15 L net for water and 20 L net for dust bags), an integrated synchronized power socket for auto-start power tool pairing, and a robust 9 kg canister design with 4 wheels. Key advantages include a patented semi-automatic filter cleaning system for consistent suction recovery, a high-efficiency H13 HEPA filter capturing 99.95% of fine dust particles down to 0.3 microns, and a large-surface pre-filter that extends the main filter's lifespan threefold. However, its notable drawbacks include a relatively high operating noise level peaking up to 92.9 decibels, a moderately heavy weight, and the fact that a dedicated blowing hose must be purchased separately to use its integrated exhaust blower function.
