Ideas for housekeeping when you're not actually at home?!

[ScrambledMeg]

Bear with me... it's hot. I had this idea that there could be tasks I could do when I'm NOT ACTUALLY AT HOME that would help me stay organised.
I've come up with the following:
Always put bleach down the toilet so it can clean it when I'm not there
Go online to sort out energy providers etc

There must be other things I could do too?! Anyone got any out of home housekeeping hacks?!

Declutter emails, eBay watch list, mailing lists etc.

Online food shopping and meal planning.

online shopping is the big one
submitting readings for electricity and gas
using a timed slow cooker to have a meal ready for when you return home
sort out insurance
remove limescale from taps using kitchen roll and vinegar in to soak

Set timers for washing machine, robot vacuum etc to start whilst you are out

Yes when my roomba is actually working its a great thing to have on during the day
