No, you should not. It can be tempting to clean your work area with whatever vacuum tool you have on hand, but the truth is that sawdust, cement, and larger debris will only ruin your vacuum cleaner. Their filters are not equipped to handle the coarseness of workshop messes, and your vacuum cleaner will end up completely totaled. For your small workshop, stick to the right tools, and in terms of cleanliness, get a dust collector.
