My daughter was gifted a toy Dyson ball vacuum for her birthday (in October) and she loves it, only issue is, it takes 4 of those fat C type batteries, a pack of four here at the cheapest is about £6, the batteries on this toy vacuum last about 2-4 weeks, I managed to stretch changing them to every 2 months (by telling my daughter I'll change the batteries later until she forgot - eventually remembering again repeating cycle until I actually changed them), however I worked out that still costs about £36 a year, which is insane for the running costs of a TOY.
So I found a secondhand stick toy vacuum that actually looks cuter and takes normal AA batteries, I bought it for £5.53 with delivery from vinted, sold her old one for £7 and am now no longer spending 3 times more than it costs to keep our ACTUAL VACUUM fully charged at all times... #finance source
