Vacuum bags — write the install date on the bag collar
Vacuum bag
When you install new vacuum bags, write the date on the collar so you know when suction loss is age vs a clog — one beat for vacuum lost suction checks.

New vacuum bags go in faster when you write the install date on the cardboard collar with a marker. Months later, that date tells you whether vacuum lost suction is an old bag or a fresh clog.
Write the install date on the vacuum bag collar
- Before seating the new bag, write month/day/year on the collar face that stays visible when the door closes.
- Seat the collar fully on the inlet so the door latch closes without crushing the date mark.
- When suction drops, read the collar first — a weeks-old bag with weak pull points to hose or filter clog before another bag swap.
- Replace on the maker’s fill line or your written interval, not only when the bag looks “still empty” from outside.
Honest stop: never run the vacuum with the bag door ajar to “finish a room,” and stop DIY if the motor smells hot after a correct bag — unplug and service.
