SHARKAV911SDirt, you’ve met your match! One problem that many robot vacuums seem to share, is that constantly emptying the vacuum is a tiring chore. Might as well manually vacuum for that price! The bagless base in the Shark AV911S holds up to 30 days of dirt and debris, so you can get the peace of mind you wanted to begin with. And-no continuous expense of a bag! The deep cleaning power and multi-surface brush roll is perfect for pet hair, as well as any other dirt that dares get in it’s way. Row by Row Cleaning No messy and inefficient bumping around here! The Shark EZ Robot has a methodical and patient row by row cleaning path, ensuring that your entire room gets covered. Or uncovered, depending how you look at it. Auto-Recharge and Resume Vacuum running out of juice? Like the self-emptying base, this is just another thing that should not be your job to worry about. When the robot vacuum detects the charge running low, it returns itself to the base. And as soon as it is ready, it picks up right where it left off. Don’t like pushing buttons? Start cleaning with Alexa or Google Assistant, or a quick tap on the app.
