At first glance our testers looked at the Oreck Halo Vacuum and questioned what the big deal was, after all the reality is that it looks like just about any upright vacuum. As it turns out, that’s what makes the Halo Vacuum special, it uses familiar vacuum designs and functionality but adds a very special hi-tech twist. A UV-C light that shines underneath the unit by the suction and the sweepers. This light actively kills many germs, bacterias, and viruses that can be found on your floors. Now we cannot verify the claim of killing 99% of these germs but our testers did report suffering less effects from seasonal allergies. It makes sense, if you consider what we track into our homes on a daily basis. As a vacuum the suction and general cleaning were on par with traditional vacuums. So the UV-C killing is really an extra added bonus.
