I've never heard anything so bloody daft as "the brushes need to bed
in"!!!
Oh Please!!

In fact, are there any brushes??!! Most new appliances use induction
motors.

Even so, the bedding in of brushes in a fallacy.

It's probably a bearing and if anything like our NEW Hotpoint will need a
replacement within weeks.

New brushes don't make noise - poor quality or badly lubricated bearings
do!
Manufacturers these days use the cheapest possible bearings and don't use
much (if any) grease.



Brushes bedding in my arse!

When I replaced the brushed in my vacuume cleaner, it wined for a few uses!
