Which is better for pet hair?

The Dustin has more suction at 8000 Pa versus 4500 Pa, so it pulls more hair off hard floors in one pass. The Bio's dual-brush system and self-empty dock still make it the easier daily pick for a heavy-shedding home.

Is the Bio worth it over the Dustin?

Yes for most people. The Bio is $159.99 at eBay versus $189.99 for the Dustin at Target as of November 7, 2026, and it adds a self-empty dock, LiDAR maps and no-go zones for less money.

Which one empties itself?

Only the Bio. Its station seals debris in a 3.5 L charcoal-lined bag, rated for about 100 days. The Dustin has a 1 gal bin you empty by hand.

Which has better navigation?

The Bio. It uses LiDAR with QSLAM to map rooms in minutes and saves multiple floor maps. The Dustin lists smart navigation but no LiDAR or saved maps.

The Bio is rated at 65 dB. bObsweep does not publish a noise figure for the Dustin, so the Bio is the safer bet if noise matters.

Yes. The Dustin uses dual-scrub mops and the Bio uses a motorized wet mop. Neither is a substitute for a dedicated hard-floor scrubber on tough stains.
