How does a Roomba work

A Roomba is a robotic vacuum cleaner that means it can clean a room by itself. The Roomba was introduced in September 2002. Roomba's have sensors to help them navigate and guide them around the room. Roomba's can clean under the couch,on the carpet and hard floors. The Roomba can clean for 1-2 hrs but after weekly for a year or 2 you can find the battery power dipping low as 30-40 mins that won’t be able to clean a room. You're probably wondering where you can get this marvelous robot. You can get them at Harvey Norman, bed bath and beyond, Noel Leeming and Dick smith. They cost around $500 - $900 some even cost $1,000 cause the new ones have to be connected wifi and might come with remotes depending on the type Roomba. Hope you learned something about the Roomba.
