Which is better for pet hair?

The Dreame L40s Ultra. Its HyperStream DuoBrush is rated to detangle hair up to 11.81in, and 19,000Pa suction pulls more from carpet. The Dustin is marketed for pet hair but lists only 8000Pa and no detangling brush.

Do I need carpet cleaning?

If yes, pick the Dreame L40s Ultra, which lists carpet and rug cleaning. The Dustin's specs list hard floors only, so it is the wrong pick for wall-to-wall carpet.

Only if you have rugs or heavy shedding. At $999.99 at Dreame as of November 7, 2026, it costs about $887 more than the Dustin at $112.82 at kitchenincorporated.org. For hard floors on a budget, the Dustin covers the job.

The Dreame L40s Ultra, because its PowerDock washes the pads in 167°F water and dries them with hot air, so you are not handling wet mops. The Dustin has dual-scrub mops but no stated dock washing.

Which is easier to move and store?

The Dustin, at 6 lb and 3.5in tall. The Dreame L40s Ultra weighs 29 lb and needs room for its PowerDock station.

Which has better filtration?
