We wouldn’t recommend the Coral One robot-handheld hybrid at any price. It’s uncomfortably loud—by far the noisiest vac we’ve ever tested. It sort of converts into a handheld vacuum, but it’s very heavy, and you’ll need to remember where you put the awkwardly shaped nozzle. In another test, I pour out about an eighth of a cup of all-purpose flour across an area rug and bare floor and let the bot try to suck it up for a couple of minutes. This dust-pickup test gives me a visual gauge for each bot’s raw cleaning power.
It’s also among the quietest vacs we tested – 58 decibels on quiet mode and 65 on high suction. If you have particularly skittish pets, the low-decibel output is less likely to startle your fur friends. I spent most of that time installing firmware updates after connecting to the app.
Do note that maximum run time is calculated with the robot vacuum running in its lowest suction power setting. If the Roomba i7 runs out of battery power while vacuuming, it will return to its dock, recharge, then resume cleaning where it left off. Since most rooms have furniture and objects bissell crosswave cordless scattered throughout, the best robot vacuums are able to internally map and adjust the cleaning pattern accordingly. Roombas that include cameras and mapping will get to know the environment and potential obstacles, then utilize that data to create adaptive cleaning patterns.
That said, allergy sufferers might prefer the comparably priced Roomba i3+ EVO, which empties its bin into an AllergenLock bag so you’re not exposed to dust. This top-of-the-line model is suitable for those with deep pockets who are willing to pay a premium for convenience. With long battery life, strong suction power, and AI-powered obstacle avoidance technology, the X1 Omni is an excellent option for large homes, and those with pets.

Because our goal is not just to create a home that’s smarter—it’s to create a home that takes care of itself. But they’ve slowly become an everyday appliance that can help you stay on top of your housekeeping. Replace filters and side brushes a few times per year, the brush roll about once a year, and the battery as needed—probably every second year, though that depends on how often you use the bot. The next important task for a robot vacuum is to cover as much ground as possible, as efficiently as possible. They’re basically fine, but they won’t match the agility of the Eufy or the durability of the Roomba. We bought one of the Goovi models, and lo and behold, we found that it is functionally identical to the 11S, with many of the same components and even the same beep and boop sounds.
