I've never had a cleaner before so had no idea what to expect. The cleaner in question started cleaning DH's office a few weeks ago and he was very impressed so he suggested she do a few hours in our house.
Cleaner left having spent 3 hours deep cleaning the bathroom. She has thrown away lego, bath toys (plastic and not mouldy the slightest), DD's bobbles off the windowsill, the bath plug, the detergent draw of the washing machine and loads of random bits of toys.
She has rearranged some cupboards in the DC's room so the vacuum no longer has a home and DS2's trousers are now stored in a big gift bag with other things on top. The cleaning supplies and spare toiletries are displayed very nicely though!
I've spent 20 minutes going through the bin bag of things from the bathroom (which included the contents of the bathroom bin
) to find the plug and picking out all the other non-rubbish and I still have to redo the cupboard. 
AIBU to not have removed all these things, should I have been checking what she was doing?
