Here’s how the Jetbot works: Using the company’s Dual Spin technology, two pads attached to the Jetbot spin at a fast rate while the robot itself turns and moves around the room. Its smart sensor system detects walls, furniture, stairs, and even carpets, so the robot mop won’t fall down steps or get your spot-clean-only rugs wet. It comes with eight cleaning modes such as “focus mode” that concentrates on a particular area, “manual mode” that allows you to control the robot with a remote, and “edge mode” that deep cleans the edges of your walls. To turn the robot into a handheld scrubber, simply set the robot mop to manual mode and lift it onto bathroom tiles, kitchen backsplashes, or glass panels that you want to deep-clean. When fully charged, the robot mop can run for 100 minutes, so it should be able to go through multiple rooms in one go. The pads on the Jetbot are washable, too, and its reservoir can also take water-based floor cleaning solutions. Another shopper even preferred it over their iRobot 240 Braava Jet. “Although it doesn’t have a virtual wall feature, which I really want, it gets the job done way more thoroughly than the iRobot 240 because of its more advanced sensors and navigation algorithm,” said the reviewer. So if you’re in the middle of spring cleaning and can’t be bothered to mop up your floors yourself, grab the Jetbot instead—while it’s on sale.
