18 month old battery lasts 90 minutes
I have the S8 MaxV Ultra and I have been using it for 18 months. Suddenly it seems to have to return to the dock to recharge after 1.5 hours. Is this still a good amount of time for the age of the battery? I was told they can last 3 years or longer. I have the same settings since I bought it. Balanced vacuum but I do have Carpet. Boost on. Also it does a two pass in the master bedroom and the kitchen. Should I leave Carpet Boost on all the time if I have pets that shed a little?
