How old is it please - Ian
Hi Marilyn, how long does it currently run for before it cuts out?
Sorry about the delay, it sounds like the battery is not charging or has failed.
Even with the cleaner being plugged in for 10 minutes you should get a good 2-3 minutes use, to this end believe you need to look at a replacement battery, since the unit is under a year old I would contact Black and Decker arrange for a replacement unit.
