Amazon offers the Hoover Quest 700 Bluetooth Robotic Vacuum for $195.32 with free shipping. That's the lowest price we could find by $5, although we saw it for $51 less in February. It features a tri-clean system, cliff sensor, 90-minute run time, and automatic recharging. It can be managed via the Hoover app for iOS or Android.

Update: The price has dropped to $194.72.
