With glides now I think the judders, sticking and hard to push is a thing of the past.
If I am just cleaning then the way I wand sets the pile in the same direction anyway, not leaving triangles which if not wanded out should be brushed out.
A lot of web sites of cleaners here show a wanded carpet with triangles everywhere which is frightening by itself as by the book we should all brush a carpet after it has been cleaned. Some carpets no but the "average" carpet should be brushed after it has been cleaned.
Rob, you mentioned you dont use the rake anymore. Do you not apply protection then? Not a problem if you dont as a lot of people dont, just wondered.
Best, Dave.
