I love my house master deluxe by cons I do not know why they say in the pub WHICH ARE anti adhesive well and indeed mine took basically the 1st day and it is getting worse I wish I had the bowl individually but can not find a service after sale So I am with unr obot that attaches to the bottom Yet I much respect do not use aluminum utensils I used as plastic or wood utensils Wash with soap and water as préconniser But then it's going to become almost unusable too attached to the bottom a shame as super convenient multifunction device
