Verdict

The Bosch Professional GAS 15 PS is a versatile 1100W wet-dry vacuum cleaner and dust extractor featuring a 15-liter gross container volume (10-liter net dry and 8-liter net water capacities), a maximum airflow rate of 53 l/s, and a maximum vacuum pressure of 270 mbar. Key pros include its multi-functional 2-in-1 design that shifts between vacuuming and blowing, an integrated automatic start-stop power socket system for seamless power-tool dust extraction, a semi-automatic filter cleaning system for enhanced efficiency, and a universal dustbag holding system compatible with both household and industrial bags. However, notable cons include its lack of an automatic cable-winding reel, rigid plastic attachments that lack a premium feel, and the minor inconvenience of needing to manually remove the dustbag when switching from dry to wet extraction.

What customers like about Bosch Professional GAS 15 PS?

  • Excellent suction power that efficiently handles fine construction dust and heavy spills
  • Synchronized power socket with automatic start/stop function for power tool dust extraction
  • Versatile 2-in-1 design capable of shifting easily between vacuuming and blowing modes
  • Innovative bag holding system compatible with both universal household and professional dust bags

  • Lightweight, compact build with a functional wheelbase that is easy to maneuver on site
  • Long hose provides ample reach when connected to machinery

What customers dislike about Bosch Professional GAS 15 PS?

  • Net container capacity is relatively small (10 liters for dust, 8 liters for water) and fills up quickly
  • High operating noise level (around 80 decibels) makes it louder than typical domestic vacuums
  • Stiff, rough, and rigid hose and extension tubes lack the flexibility needed for delicate indoor home use
  • The standard floor brush attachment has hard bristles that are less suited for delicate residential surfaces
  • Switching between dry vacuuming and wet waste extraction requires removing the dust bag, which can be tedious
  • Some regions require an adapter due to the provided European-style earthed plug
