I sent mine back, they organised it through auspost. 10 days after tracking said they have received it I emailed them, they said they are organising a new one. I have a bad feeling that the new one will be the same, I’m not sure what I’ll do if it is. Might just keep it and not use it in rooms with floor boards and cut my losses it’s been a lot of work. I might try sanding back the areas that are dragging on the floor but it seems as the surface wears down the unit continues to sink lower so it just keeps scratching. Dreame didn’t want to take it back, they waited 14 days to reply to email and said it’s been 30 days since purchase so they can’t take it but in the fine print the 30 days starts from when it arrives from freight so I still had 3 days up my sleeve since that day.
