Yes, the mc will cope with that fine. It will mean that you do not have to take the mc indoors. The hose will reach all over most houses. I have a 3 m , 2 7.5m and a 15m on the van all the time. on one job every 3 months most of that is on the mc to save a very difficult flight of stairs. With that much hose on a porty it reduces the airflow but I find its not too bad. The 3m hose is used a lot-- how many times is a 7.7 just not quite long enough? It is easy & quick to put on.
