User Manual Roidmi H10 Cordless Vacuum Cleaner

The vacuum is left on charge all week as it's at my elderly mother's house and I clean only once a week. I always leave my vacuums on charge, though not sure if that's a good idea or not. I've been told electricity cuts off as soon as vacuum is charged fully.

Hepa filters that need changing every 3 months but very difficult to find. Always starts in low power
