I am about to buy this tool . So a quick check to see if its what I need . I have an extensive scraping job to get old paint of walls ..layers and layers some of which are oil based. The plaster is fine so its just the paint that needs to come off. This bosch tool has a vacuum attachment so one of the main questions is will the vacuum work for scraping . I see there are soft scraper blades and hard scraper blades some info and usefulness of each would be nice too.
