The customer-loved robot vacuum features a powerful three-stage cleaning system with dual brush heads that loosen and trap dirt, dust, and pet hair from all floor types. It comes with edge-sweeping brushes that operate at a 27-degree angle to sweep dirt from your walls. The smart vacuum also has dirt-detecting sensors that increase its suction power in high traffic areas—and it has a patented AeroVac filter that traps allergens, dander, dust, and pollen, according to the brand. To buy: $179 (was $300); amazon.com. Along with the advanced dirt-detecting sensors, the vacuum also has smart navigation sensors that allow it to adapt to your space and maneuver around corners and furniture as it avoids edges, like stairs and balconies. The robot vacuum runs for up to 90 minutes before automatically returning to its base to recharge. All of these features are controlled through the iRobot mobile app or voice control, where you can schedule cleanings and receive suggestions during allergy and pet-shedding seasons, too. “I cannot believe how much hair it picked up even after I swept my floor,” said one shopper with two cats and two dogs. They also added that their floors have “never looked cleaner.” Another reviewer said the Roomba changed their life because it’s so effective at picking up pet hair.
