We have a brand new Bighorn 3010RE and love it. My wife is not to fond of the Dyson vacuum cleaner. At six minutes use at a charging it will take 3 days to clean the trailer. The battery lasts 6 minutes on high and takes 3 1/2 hours to charge. You have 12 minutes on low but don't work very well. Nice idea but not very good Vac. at 6 minutes use at a time.
