Is my cleaner not very good ?

[TypicallyTopically]

Hello. 3 bedded terrace. She cleans for 2 hours. I've noticed the following...
Rug where dog lies not hoovered
Child's desk not cleaned.
Behind taps left dirty.

Aibu to expect a better job or is this OK to be left if only cleaning for 2 hours?

It's not long enough.

It takes me 2 hours to clean my one bed apartment.

Oh really? She recommended 2 hours. Maybe I'm being harsh.

So in 2 hours I should expect what? Carpets hoovered, wood floors cleaned, kitchen surfaces done, bathroom cleaned ie toilet and bath ?

No way 2 hours is enough to clean to a decent standard.

Impossible to say what can be done because of the variables, op.
Mainly how much stuff you have, and how thorough you want the clean to be.
