Put it like this - hamsters sleep all day. You put food and water out once a day and if they have enough space in their cage and a cosy house and nest, they more or less sort themselves out mostly.
If it's cleaning you're worried about then here's a tip. You don't need to do it very often at all! The key is to have plenty of substratein the cage - at least 4 to 5" deep - and use a litter tray.
Pet shops usually tell people to clean everything once a week. This is not the case and is very bad for the hamster. The best thing is to never clean everything at the same time - and just "spot clean" occasionally and/or empty the litter tray and refill it every few days and the rest of the cage stays clean and dry. You do the wheel, as and when, and any toys as and when (toys often don't need cleaning very often at all) and do the substrate/litter at a different time again - and if you use a litter tray or spot clean you can easily go about 2 months before needing to change the substrate.
They will use a litter tray if you put it in the right place - which is the place they have chosen as a toilet for peeing - often a corner of the cage. They are quite clean little things really and like to keep their toilet separate. It's usually only baby hamsters who have accidents and pee in the nest at first.
So a few really simple things and the whole thing just ticks over with hardly any effort:
1) A good sized house (a child's shoe box or an adult shoe box if you can fit one in - made with a hole cut for a door - cut the base out and keep the lid as a lift off roof - the house is best open underneath and sat on top of the substrate). The hamster will build a large nest in this and fill it - and they tend to look after their nests if they have enough room to build a large one. They tend to bury hoards under the nest and snack from their hoards. Dry hoards are fine to leave for quite a long time.
You can check inside the house by lifting the roof off - that stops their nest falling apart as it upsets them if anyone messes with their nest or hoard - and then they start peeing on the hoard to deter anyone taking it away!. If all is dry it is fine. If it's pee'd on you need to remove some of the nest and hoard but try and leave some dry behind, and then add a handful of new food in exactly the same place as where the hoard was - so they don't get stressed and start peeing on the hoard. And add new nesting material in a heap in the cage (not inside the house) so they can pouch it, take it to the nest and rebuild it.
This is the main thing for giving them normal behaviours so there is less cleaning to do - a good sized house, left alone mostly, and a litter tray.
The more substrate there is, the less likely the cage needs cleaning, so the substrate lasts longer and it works out a lot cheaper. And the hamster is happier because they can dig, move the substrate around in heaps and burrow down further in their nest.
2) A wheel that's big enough - 8" diameter minimum,but ideally about 11" diameter. Anything smaller than 8" and they can get back problems and need vet care.
3) Leave the set up as it is - hamsters scent mark their cage to find their way around and so it's familiar territory for them (why it's best not to clean everything at the same time so something always smells familiar).
4) Apart from occasional out of cage time they are then more or less self sufficient! You just put food and water out once a day, at the time that suits you, and give them a chew stickand the occasional treat.
