They are especially easy to use on carpet, but less convenient if you need to vacuum many different floor types. Canister vacuums can be used on both carpet and hard floors, since they usually have both a beater attachment and small nozzles to choose from. If you don't have one now, the only thing keeping you from one is a few thousand dollars. All the machines vary in power and claims about how little dust they release while you vacuum. Reading reviews such as those published in Consumer Reports can help you match your needs to the right kind of vacuum.
Nothing really beats a test run, though.
Consider only buying a vacuum after going to a shop and really running one through its paces. If you have a fussy baby, consider using vacuum time as a calming exercise. Some babies love the sound, and most would enjoy being worn in a sling while you move about. Take that time to do your twenty-second meditation and pat the baby.
