Choose the floor behavior and enable resume
Use Dreamehome for carpet and cleaning settings. The robot supports removing its mops for carpet vacuuming; the cited guidance recommends avoiding carpet pile over 3 mm. The 0.4 in (10.5 mm) mop-lift difference is not an approved pile-height limit.
Enable recharge-and-resume in the app if you want that function. If the robot will not connect during setup, check the manual’s 2.4 GHz network requirement before changing unrelated cleaning settings.

Treat region support as a separate purchase check
The cited app and setup information covers the US model. Cross-region account use, cloud access, firmware availability and warranty remain unverified here. Ask official support about the exact sales version and intended country before importing; do not rely on an unverified region-switching workaround.
