Stick Cleaners are light weight and cordless with rechargeable batteries. There is a big variation in cost between the different makes and models on the market and you really do get what you pay fore so its well worth spending a little more money and getting a good quality maket, we highly recommend the Bosch Athlet.
We are so impressed with the Bosch Athlet unlike many stick vacuum cleaners they have some real grunt and makes short work of your carpets and hard floors. Weighing just 3.8kg its light enough to carry up and down the stairs with very little effort. Bosch have used all their battery technology and expertise from their professional cordless power tools to develop a cordless cleaner with a decent runtimes and the Bagless Technology will save you money on bags.
