DREAME H14 Cordless Vacuum

Yes, and it's the H14's strongest point. After each use it runs a hot-water self-clean on the roller and then dries it quickly, so the roller stays fresh between cleans. Of everything on the DREAME H14, this is the feature that comes up most often.

Often, yes. Suction on the H14 is strong, but heavy debris can clog it or get left behind, so a quick sweep or dry vacuum first is a common routine. Treat the DREAME H14 as a wet cleaner for floors that are already mostly clear of crumbs and grit.

Yes. The H14 lies flat to clean under couches, tables and kitchen kickplates without moving furniture, and the suction holds up in that position. At 14.7 lb, though, it's a heavy machine to lower that far, so expect your arms to feel it on a long session.

Usually not, but it depends on the floor. Pet hair goes through without tangling in several homes, while in at least one it still wrapped the roller unless the floor was swept first. DREAME says a comb-toothed scraper clears tangled hair from the H14's brush on its own.

Water left sitting in the tanks goes stale. The fix is simple: empty and rinse both tanks on the DREAME H14 after each use and leave them to air-dry before you put the machine away. Skipping that step is what leads to the smell.
