The Bosch GAS 35 M AFC is a 35 litre M class wet and dry dust extractor built for site use with sanders, saws, wall chasers and SDS drills. Its headline feature is automatic filter cleaning, which keeps suction strong without stopping work to tap the filter. A power tool socket and an antistatic hose complete a package aimed at trades who need M class extraction every day.

In its favour

- Automatic filter cleaning keeps suction steady during long sanding or chasing jobs.
- A power tool socket switches it on and off with the tool, and the 5 m hose is antistatic.
Good to know
- The listed weight of 18.9 kg makes it heavy to lift into a van.

Our take
Certification and suction
Bosch states the extractor is certified as M class to the European standard, which is the usual requirement on UK sites for hardwood, MDF, plaster and concrete dust. The specs give 1,380 W of power and a 35 litre container.
A wet and dry design means it can also pick up water from core drilling or a leak, which a dry only vacuum cannot.
Automatic filter cleaning
AFC is Bosch's automatic filter cleaning system. The listing says it lets the extractor keep constant suction, and in practice that matters most with fine dust from sanding or chasing, which blinds a filter quickly. Without automatic cleaning, you have to stop and clean the filter by hand to restore airflow.
Working with power tools
A socket on the extractor powers your tool and switches the extractor on with it, with a delayed shut off so the hose clears after you stop. A 5 m antistatic hose with a power tool adaptor is included, and antistatic equipment is listed to avoid static build up. The listing also says an L-BOXX can be clipped on top for transport and storage.
Size and weight
The specs give a weight of 18.9 kg and dimensions of about 52 by 52 by 58 cm. That is a substantial unit to lift into a van or carry upstairs. The listing text is short and partly machine translated, so some details such as the number of power levels may not be reliable.
Other options
The Trend T35A offers M class certification, automatic filter cleaning and auto start in a lighter 6.5 kg body with a 27 litre drum. The Bosch GAS 18V-12 MC is a cordless M class choice for small jobs away from power. The GAS 35 L AFC is the L class sibling for wood dust only.
Verdict
Buy the GAS 35 M AFC if you need a full size M class extractor with automatic filter cleaning and a tool socket for daily site work. If weight is a concern, the Trend T35A is much lighter, and if you only handle wood dust in a workshop, the Bosch GAS 35 L AFC is the lower class alternative.
