If you’re unsure what deals to shop during Prime Day, why not head for the sales on essentials you know you’ll use non-stop? The Shark IQ Robot Vacuum is one that will see plenty of use throughout the summer and the rest of the year, and right now it’s marked down to $300. The biggest selling feature of this robot vacuum, compared to others, is that you can forget about it for up to 45 days because it’s a bagless model with a base that automatically empties itself whenever it’s full. To buy: $300 (was $550); amazon.com. “My expectations have been exceeded on almost every level by the Shark IQ Robot vacuum,” began one five-star reviewer who said they like the Shark model more than their Eufy robot vacuum. Calling the self-emptying bin a “game-changer,” they continued, “I am very happy with my purchase.” “Love this vacuum,” wrote another reviewer who said they previously cleaned their floors twice per day before purchasing the Shark robot vacuum. They added, “Set up was truly simple, and [the vacuum] had the house mapped in about three runs…The app seems to work well, and we have had no issues. Highly recommend.” No matter how many features a robot vacuum includes, its superiority ultimately comes down to how well it cleans. Shark notes the vacuum self-cleans while it picks up dirt, debris, and crumbs to prevent things like hair from coiling within the model. Plus, the brand notes that it has powerful suction and the ability to clean row-by-row to achieve a spotless space—and shoppers agree that the pet-friendly vacuum works. “It’s amazing how clean the house is,” said another reviewer. “I swear [the vacuum] picks up enough pet hair in a week to knit a sweater.” Save $250 ahead of Prime Day when you add the Shark IQ Robot Vacuum to your cleaning rotation, and enjoy your new gadget that will do all the work for you—and keep you from emptying the base for more than a month at a time.
