Shark AV2820S Self-Empty Robot Vacuum with NeverStuck Technology
Stop wrestling with your robot vacuum's stubbornness. The Shark PowerDetect Self-Empty Robot Vacuum is built for homes where the floor plan is anything but simple. With NeverStuck Technology, it lifts and lowers to glide over electrical cords, rug tassels, and low furniture, so you don't have to rescue it from under the couch again.
This vacuum automatically tailors its cleaning. On hard floors, the brushroll lifts to avoid scattering debris. When it transitions to carpet, the brushroll engages to deep-clean, and the motor boosts suction anytime it senses hidden dust or dirt. EdgeDetect fires blasts of air to pull debris out of corners. After each run, it empties itself into the HEPA-sealed, bagless base that holds up to 30 days of dirt. You'll never touch a disposal bag.
The 3D object detection identifies small and tall obstacles. You can set schedules or target specific rooms via the app. For pet hair, allergens, and daily messes, this vacuum works without hovering over it.
