Verdict

The Bosch AdvancedVac 18V-8 is a cordless, 3-in-1 wet-and-dry vacuum cleaner weighing 3.8 kg (without battery) and featuring a gross container volume of 8 litres for dry material and 3.8 litres for liquids. Operating on an 18V Power For All alliance battery system, it delivers a maximum airflow rate of 29 l/s and a maximum turbine vacuum of 92 mbar, providing up to 24 minutes of runtime in eco-mode with a 4.0 Ah battery. Main pros include its versatile functionality as a vacuum, integrated inflator/blower pump, and power-tool dust extractor via a universal adapter, alongside a lightweight and highly portable wheeled design with dual power settings. However, notable cons include its mediocre suction power for heavy-duty construction tasks, the lack of an automatic filter-cleaning system requiring manual maintenance, and the fact that the battery and charger are sold separately.
