Choose a construction vacuum without battery if you don't need another battery. As a DIYer or contractor, you probably already have plenty of batteries of a certain brand which are compatible with the construction vacuum of your choice. This means you can easily exchange the Makita 12V Max battery of your drill to your construction vacuum and save on unnecessary costs for a complete set. A big advantage of a cordless construction vacuum is that you have complete freedom of movement without cords, so you can clean thoroughly after your job.
