It's back! You usually only see Aldi selling this once a year (usually on a Wednesday in Nov/Dec) so I'm surprised it's available again and this time on a Saturday (14 June)!
I own one and find it really good. Some people might find it noisy but for the price (compared to major brands), I'm happy to put up with some whirring and beeping. I usually just let it run until it runs out of juice then my partner and I play a game to see who can find it first.
[EDIT: this model does return to charging dock when it is low and goes off cleaning again when it has had it fill. I don't live in a large place so one round on one charge every other day is more than enough for me. ]
Does anyone know which 1 would be better? Aldi or Kogan?
