Yes, You Need a Different Vacuum For Different Tasks — Here's the Breakdown

For time-pressed people, a robot vac is the way to go. The coolest thing about this Shark Ion Robot RV772 Vacuum ($280) is that it's voice activated. Get your girl Alexa's attention, and the Shark will roam your home, sucking up dirt and dust from carpets and hard surfaces alike. It's smart enough to "know" your home, so it won't go careening down the stairs. And because you can control it from afar via app, you can get your vacuuming done while you're at the library, park, pool — anywhere.
