After a few weeks of use, I've been happy overall with this vacuum. It does a great job picking up cat hair, dust, and crumbs from wood and cement floors. The only real negatives are the battery life (could be bigger) and the power head size (could be a bit larger). Using the high power mode is ideal, especially for cat litter and heavier dirt, but that really drains the battery quickly. The omnidirectional power head movement and soft rollers spinning in opposite directions (push everything to the central suction port) are both excellent design features. Value for dollar, I would definitely buy this unit again.
