Keep in mind that this price is good today only, as it is part of the Gold Box Deal of the Day. And it will expire at midnight PST tonight. It’s also one of the cheapest robot vacuums that can empty itself. Which seems to be the new big feature for robot vacuums these days. It has some pretty powerful suction. Deep-cleaning power to take on large debris, small debris, and pet hair on carpets and floors. Removes pet hair and long hair from the brushroll—no more hair wrap. Angled side brushes dig deep into edges and corners for complete cleaning of dust, dirt, and debris. Powerful suction and a re-engineered brushroll combine with a high-efficiency filter that captures dust, dander, and allergens. Select which rooms to clean immediately—or schedule a whole-home cleaning—through the SharkClean app. The robot returns to the base, recharges, and can pick up where it left off. After every cleaning session, your robot automatically empties into a bagless base that holds up to 30 days’ worth of dust and debris. Forget about vacuuming for up to a month. Which is arguably the best feature of this robot vacuum from Shark. And the biggest reason to spend $550 on this one. Not only is it convenient, but it means that you won’t have to worry about spilling dirt and dust on the ground when you empty it.
