Can a robot vacuum get over high door thresholds?
Short answer
Yes, for steps of a few centimeters. The Dreame X50 Ultra lifts itself over raised thresholds, though it won't climb a staircase.
Which robots can do it?
- Dreame X50 UltraYes
The X50 Ultra climbs over raised thresholds on its own; Dreame quotes up to 6 cm.
Good to know: One threshold in a hands-on review only worked after it was marked passable in the app.
Why it matters
Raised thresholds between rooms trap robot vacuums, so bathrooms and laundry rooms often get skipped.
Not proven yet
How reliably it clears every threshold type. One reviewer had to mark a threshold as passable by hand.
