For the record, I wasn't paid to write this review, but I'd love to promote Yufi if I could. I didn't hesitate to tell all my friends about my little Yufi and showed them the vacuum cleaner in action when they arrived. I can't stand vacuuming. Eufy comes and after much research I decided to catch him; I absolutely LOVE this vacuum cleaner! It has already vacuumed my entire 1,900 square foot house with no problems and has easily switched between carpet and hardwood. It's very quiet and fits under some of my furniture which is a bonus. Since my house is mostly carpet, I get about an hour on each charge at full suction. Eufy finds his way home, charges for about 5 hours, and then goes back to racing. You can also schedule when he should clean up; There is nothing better than coming home to a clean house after a long day. Upstairs I close the door of each room I want to vacuum and wait 10-12 minutes per room. I open the door and there is a beautifully cleaned carpet. And let me also say this thing WORKS. I keep the house clean but I was shocked at how much dirt, hair and dust this kid sucked out of my floors. This is technology at its finest and I am a happy camper. Boundary strips are also a great addition. Do yourself a favour: buy Eufy. You will not regret it.
