There is something about summer that always seems to bring extra dirt and mess into the home, but, between the heat and many daily activities, I know the last thing I want to do is vacuum. While robot vacuums can be quite costly, right now, the Shark AI Ultra Voice Control Robot Vacuum with Matrix Clean Navigation is half off on Amazon, dropping its price to 300 from 599. It's a version of one of our favorite robot vacuums, the Shark RV2502AE AI Ultra -- which also retails for 599. That one is 40 percent off right now, down to 360. Shark's AI Ultra Voice Control Robot Vacuum with Matrix Clean Navigation is a great option if you're looking for a robovac that offers a bit of everything. As the name suggests, it offers features like voice control, which lets you start or schedule a clean through Amazon Alexa or Google Assistant.
