The suction power doesn’t stand up to these larger devices, and the collected debris is pulled into a small internal bin with limited dustbin capacity. After I determined there was no chance I could clean the pet waste off my robot vacuum, I reached out to the manufacturer. And, even though the warranty states explicitly these accidents aren’t covered, they still provided me with a replacement unit for free. I plugged in the dock to charge the vacuum, connected the app, updated the firmware, and set a schedule for cleaning. After two cleanings, the vac created a map of my layout so I could set no-go zones to keep the T8 AIVI away from sensitive areas. The 240mL water tank was large enough to complete at least two passes over the 500-square-foot test floor.
While not as effective as the top performers on our list, it still managed to pick up 88.9 percent of all debris laid before it. It is a much better performer on hard floors (94.35%) vs carpets (83.52%), which is worth bearing in mind depending on your flooring. The best robot vacuums are designed with convenience in mind above all.
The S series features a newly designed “D” shape and corner brush for optimized edge cleaning deep into corners and along edges. Other new features include an anti-allergen system that traps 99% of pollen, mold and allergens, 40 times the suction compared to the 600 series, 30% wider rubber brushes, and the most advanced bissell crosswave cordless navigation system to date. Similar to the I series, the s9+ comes with the self-emptying Clean Base. The S series also includes linking technology that allows the Roomba to communicate wirelessly with other iRobot products, where the Braava Jet M6 can automatically be set to mop after the s9 has finished vacuuming.
Also, the first- and second-generation Roombas can get stuck on rug tassels and electrical cords. Third-generation and newer models are able to reverse their brushes to escape entangled cords and tassels. All models are designed to be low enough to go under a bed or most other items of furniture.
Others perpetually got trapped under the same damn easy chair and could never maneuver their way out. Yet others somehow never connected to my WiFi network, rendering them useless when I wasn’t home. Not only can it handle both vacuuming and mopping in the same cleaning session — lifting the mop when carpet is detected — it comes with an auto-emptying dock, which Roborock claims is good enough for eight weeks of dirt.
