The Empowered Visionary. Bob makes fetching fur a walk in the park: His sensors keep him aware of his surroundings, while his TurboLift vacuum, and long brush cut a path to cleanliness. Pair Bob with the Bobsweep app to schedule, control, and track him with your smartphone. Connect him to Alexa or Google, and you can command him with your voice. Bob PetHair Vision Plus is among the industry's few robot vacuums that are 5G Wi-Fi compatible, in addition to 2.4G. More than just a vacuum, Bob comes with a mop attachment with a water reservoir for wet/dry mopping. Bob's sleek design is not only for aesthetics but also for practicality: at under 3 inches, Bob tracks dirt and pet hair down to where they like to hide. Material: Plastic.
