8. How We Tested
The debate on the best robot vacuums in 2026 is significantly different. Previously, Shark vs. Roomba was the big discussion. However, with new competition from brands like Dreame, Roborock, and Narwal, Shark and Roomba’s relevance is fading. With Shark’s inconsistent releases and iRobot’s bankruptcy in 2025, the question is more about if either is a top brand rather than which is better.
**But first, the elephant in the room**
The rivalry spiked briefly in March 2025 when iRobot restructured its Roomba lineup but soon filed for bankruptcy in December 2025. Let’s explore where iRobot excelled and failed.
**Where Roomba wins: Small obstacle avoidance and more variety**
Roomba offers more flexibility with features like smart mapping, self-empty docks, and small obstacle avoidance, which give it an edge over Shark. This variety was enhanced when iRobot released eight new models in March 2025, even amidst financial troubles. Notably, the Roomba Max 705 Combo leads with its notable small obstacle avoidance.
**Where Roomba loses: No recent innovations, still too expensive**
iRobot lost momentum as its innovation slowed, making Roombas less justified for their high cost. Though iRobot attempted to address this with new models in 2025, it wasn’t enough to prevent bankruptcy.
**Where Shark wins: Spot cleaning, affordability, and the UV light**
The Shark PowerDetect UV Reveal 2-in-1, released in March 2026, introduced unique UV light tech, distinguishing Shark more than before. Shark provides core features at reasonable prices, appealing to first-time buyers while maintaining decent cleaning.
**Where Shark loses: Small obstacle avoidance and slow releases**
Shark lags in releasing new models and innovating. Shark’s other models appear outdated compared to competitors, showcasing slower progress in areas like small obstacle avoidance.
**Where iRobot and Shark both lose: Their apps suck**
Both iRobot and Shark have outdated apps compared to rivals, offering less detailed mapping and controls.
**Our winner: Shark**
Neither brand is a top contender in 2026, but Shark edges Roomba with its innovative UV Reveal 2-in-1. Despite iRobot’s bankruptcy, it hints at future developments. Explore Dreame and Roborock for smarter and more powerful options within budget.
