Design & Build Quality
The iRobot Roomba s9+ immediately feels like a premium product. With its sleek D-shape design, it fits snugly into corners, which I found particularly effective during edge cleaning tests. The brushed metal finish gives it a modern look and feels robust.In contrast, the Shark IQ Robot has a more traditional circular design. It's lighter, which made it easier to move around when I needed to man
ually relocate it. However, the plastic finish felt less durable than the Roomba.
Winner: iRobot Roomba s9+
Features & Functionality
The Roomba s9+ is packed with features. Its advanced vSLAM navigation maps your home in real-time, and after testing, it consistently avoided obstacles, unlike previous models I've used. The self-emptying base is a game-changer, holding weeks of dust and debris.The Shark IQ Robot also offers self-emptying convenience, but its Total Home Mapping was less precise in my tests, occasionally failing to map smaller rooms. Still, its voice control with Alexa worked seamlessly, a plus for smart home enthusiasts.
Winner: iRobot Roomba s9+
Performance
In terms of suction power, the Roomba s9+ is unmatched. During my tests, it picked up everything from fine dust to larger debris like cereal. The enhanced suction power, claimed to be 40 times more than standard vacuums, was evident as it tackled my high-pile carpets with ease.The Shark IQ Robot performed well on hard floors but struggled slightly with deeper carpets. Its self-cleaning brushroll is a practical feature, especially for pet owners, reducing hair tangles significantly.
Winner: iRobot Roomba s9+
