Which is better for pet hair?

The bObsweep UltraVision lists 8000 Pa suction and a 6L bag, and pet hair is its stated top use case. The Roomba Plus 575 Combo is also sold for pets but publishes no Pa figure. On paper the bObsweep wins for heavy shedding.

Is the Roomba Plus 575 Combo worth the extra money?

Yes if you want the dock to wash and heat-dry mop pads and need the smaller body for low furniture. If you mainly vacuum and mop occasionally, the bObsweep does the core job for $105 at Walmart versus $499 at Best Buy as of November 7, 2026.

Which one mops better?

The Roomba scrubs 2x deeper than standard vacuum-and-mop mode and lifts its pads 10 mm over rugs, and its dock cleans the pads. The bObsweep mops wet and dry with a 350 mL tank but you rinse the pads yourself.

Which fits under more furniture?

The Roomba. Its body is 46% smaller and it climbs thresholds up to 35 mm. The bObsweep is 3.5 in tall, which clears most sofa skirts but not very low gaps.

Which has better battery life?

The bObsweep publishes 170 minutes of runtime with a 250-minute charge. iRobot does not publish a runtime for the Roomba Plus 575 Combo, so there is no direct figure to compare.

Do both work with voice assistants?

Yes. The bObsweep works with Alexa and Google Assistant. The Roomba adds Siri support on top of Alexa and Google Assistant.
