iRobot introduced their new line of Roomba 700 series and ultra-compact Scooba 230 recently. The new Roomba 700 series that improves its cleaning and detection over the last generation of Rommbas. The 700 series Incorporates iAdapt Responsive Cleaning Technology, the most actively intuitive robotic technology, giving the most thorough cleaning results with a new sleeker design. It also has 50% longer life than previous Roomba generations, cleaning up to four regular sized rooms on one charge. The company also introduced their smallest floor washing robot, the iRobot Scooba 230, which scrubs your tile, linoleum and sealed hardwood floors. The robot uses a squeegee and a vacuum to pick up virtually all the water on the floor, so your floor dries fast. The robot's water management system includes a flexible bladder that keeps the cleaning solution and the dirty water separate inside the robot. While the robot is cleaning, the bladder shrinks in size as cleaning solution is put down on the floor, freeing up space in the robot to hold the dirty water that is being picked up.
