How to get vacuum to fully charge before finishing cleaning

Vacuum will clean the majority of the house but then stop to recharge partially, continue vacuuming only to have to stop to charge again 10 minutes later (or even less)… thus start stop cycle continues for several hours and cycles to finish the last 30 mins of cleanup. Is there a way to have it recharge fully before initiating the remainder of the cleaning?

Mine is doing the same thing, runs for 30 min then recharge, then continues. How to fix it. Also not empting into bag.
