Try to avoid Dyson V12. Recently having problem with intermittent power off. Online google and apparently this is well known problem for V12

Using Corvan K18 pro, so far very satisfied with it

The suction quite powerful and the mop head attachment is decent at light mopping (my floor SPC type, so cannot use too wet mop), tahan quite long like 45mins+ use on full charge

Not-so-good is that can tell where they cut costs to keep it "value friendly" with the strong motor & good battery life, like the attachments are plastic and feels not so "premium", but strong and does the job well enough.

Assuming you're in Klang Valley, HomePro store sometimes have but for best test, have to go to Corvan experience store. Unfortunately they only have one, which is in Atria Mall (PJ).

They sometimes go to home goods convention but need to follow their FB to keep track
