not really I thought I needed a vacuum cleaner robot. My house is not big. Many floors are made of wood. But the standard vacuum cleaner I've used for many years can't get under beds and furniture. So I took the risk and invested in a robot. This little device is impressive. The suction power is incredible. It easily fits under furniture and beds. Cleans hard-to-reach places. And it even cleans parquet floors. This vacuum cleaner is durable. It won't get stuck in corners or tight spaces. He changes direction and just keeps going. The battery lasts about three hours before it needs to be recharged. This works great for my home. I had an issue where it would freeze when transitioning from hardwood to carpet. But when I removed the mop head (an easy five-second job), it immediately returned to its steady pace. You can't beat this little monster for money.
