Note: requires Costco Membership.
I don't know anything about robotic vacuum cleaners, but this price is substantially cheaper than anywhere else. For example, Myer have it in sale, marked down to $759. It's $50 cheaper than CostCo's regular price.
From Costco's description:
The D3 automatically adjusts suction power depending on what surface it’s cleaning and with twin power modes, you can adjust your cleaning performance to the situation. With the unique D shaped chassis, the D3 can clean close to walls and in tight spots, using an extra-wide brush to thoroughly clean your flooring. Laser Smart technology intelligently navigates and maps your home, cleaning in straight lines instead of a random pattern. Easily control your robot from your phone, smartwatch, Amazon Echo, and Google Home. Auto charge and resume allows your robot return to base to power up and then go back out and pick up where it left off.
CostCo membership is $60/year, so even if you have to pay the membership fee, it's still considerably cheaper than anywhere else.
