Bosch GAS 35 M AFC
Best OverallPros
- Automatic filter cleaning (AFC) reduces downtime
- M-class dust certification for fine particles
- Large 35 L container for extended use
Cons
- Heavier than smaller models
- Higher price point
The Bosch GAS 35 M AFC is the flagship model for professional tradespeople who need reliable dust extraction. Its automatic filter cleaning system pulses air through the filter every 15 seconds, maintaining suction power without manual intervention. Owner reviews consistently praise its build quality and the effectiveness of the AFC system for fine dust from sanding and grinding.
With 1200 W of power and 254 mbar vacuum pressure, this unit handles both dry debris and liquid spills effectively. The M-class certification means it filters particles down to 0.1 microns, making it suitable for construction sites with silica dust regulations. The 35 L container reduces emptying frequency during large jobs.
Bosch GAS 18V-10 L
Best CordlessPros
- Fully cordless for remote jobs
- Compact and lightweight
- Uses Bosch 18 V battery system
Cons
- Limited runtime on larger spills
- Small container requires frequent emptying
The Bosch GAS 18V-10 L brings true portability to wet dry vacuuming. It runs on Bosch's 18 V battery platform, so if you already own Bosch power tools, you can share batteries. Owner reviews highlight its convenience for quick cleanups in attics, basements, and outdoor areas without dragging a cord.
The 10 L container is adequate for small to medium jobs, and the vacuum offers both wet and dry pickup with a simple filter change. Runtime with a 4 Ah battery is around 20 minutes, which covers most typical uses. The compact design fits easily in vehicle trunks for mobile work.
Bosch GAS 15
Best BudgetPros
- Affordable entry point
- Good suction for its size
- Lightweight and easy to carry
Cons
- No automatic filter cleaning
- Smaller container than pro models
The Bosch GAS 15 is the sensible choice for home workshop users who need reliable performance without the professional price tag. It delivers 1100 W of power and 240 mbar vacuum pressure, enough for sawdust, debris, and liquid spills. Owner reviews note that it handles drywall dust well with the included cartridge filter.
The 15 L container is suitable for weekend projects and small renovations. It features a blow function for clearing debris from hard-to-reach areas. While it lacks the advanced filter cleaning of higher-end models, the GAS 15 offers solid value for occasional use.
Bosch GAS 20 L SFC+
Best for Wet PickupPros
- High power for liquid pickup
- Semi-automatic filter cleaning (SFC+)
- Durable metal container
Cons
- Noisy operation
- Heavier than plastic models
The Bosch GAS 20 L SFC+ is built for heavy wet pickup with its 1300 W motor and 260 mbar vacuum pressure. The metal container resists corrosion from water and chemicals, making it a durable choice for workshops and garages. Owner reviews appreciate the SFC+ system that cleans the filter with a manual shake mechanism.
This model handles large liquid spills efficiently and includes a drain plug for easy emptying. The 20 L capacity balances portability with volume. It also works well for dry debris, though the metal construction adds weight compared to plastic alternatives.
Bosch GAS 50 M AFC
Best Large CapacityPros
- Huge 50 L capacity for big jobs
- Automatic filter cleaning
- M-class dust certification
Cons
- Very heavy and bulky
- Expensive
The Bosch GAS 50 M AFC is the largest model in the lineup, designed for construction sites and heavy industrial use. With 1380 W and 270 mbar vacuum pressure, it offers the highest suction power among Bosch wet dry vacuums. The 50 L container minimizes emptying frequency during large-scale cleanup projects.
Like the GAS 35 M AFC, this model includes automatic filter cleaning and M-class dust certification. Owner reviews highlight its reliability for continuous operation with fine dust from concrete cutting and sanding. The main trade-off is its size and weight, which make it less portable than smaller models.
What to check before buying a Bosch wet dry vacuum
Container size determines how often you empty the vacuum. For small workshops, 10-15 L is sufficient. For construction sites, 35-50 L reduces interruptions. Consider the types of debris you handle most. Fine dust requires models with automatic filter cleaning or M-class certification. Wet pickup benefits from metal containers and high vacuum pressure.
Power cord length affects reach. Most Bosch models have 5-8 m cords. Battery-powered models offer mobility but limited runtime. Check compatibility with your existing Bosch 18 V batteries if you choose cordless. Warranty coverage typically ranges from 1-3 years depending on the model and region.
Mistakes to avoid when choosing a wet dry vacuum
Do not buy a model with too small a container for your typical job size. Frequent emptying wastes time and reduces productivity. Avoid skipping filter cleaning features if you work with fine dust. Manual cleaning adds maintenance time and reduces suction over a shift. Do not assume all wet dry vacuums handle liquids equally. Check the wet capacity rating and drain plug availability.
Do not ignore noise levels. Some high-power models exceed 80 dB, requiring hearing protection on site. Check decibel ratings if noise is a concern. Avoid buying a cordless model if you need continuous operation. Battery runtime limits are a constraint for large jobs. Finally, do not overlook accessories. Hose diameter, nozzle types, and filter options affect versatility.
