This vacuum is just what I needed. I have two cats and two feet of hair. I wanted something that would help me cut down on the time I spend cleaning my house just because of my hair. This is the perfect solution. I have some experience with robot vacuum cleaners but this is an improvement over my previous one. My old robot vacuum was heavy, the battery life was terrible, and it kept crashing at the slightest level change. This vacuum is lightweight, the battery life is amazing, and it easily goes from hardwood to carpet without slowing down. I have a very large ground floor with wooden floors, carpet and tiles in different rooms. When I first turned this vacuum on and let go, it went around the house with no problems. At first I was concerned it would get stuck in the transition bar between the hardwood floor and the carpet, but it took it like a champ and kept going, treating every room in the house without needing to be charged. It states that the battery life is around 2 hours, but after an hour, according to the indicator, only around 1/3 of the battery is used. The suction power is good enough for standard needs, picking up hair and kitty litter easily. , and crumbs no problem. The only thing he didn't catch was some oversized pieces of cat food. I only had to empty it after two full cleanings on the first floor of my house, which impressed me since I usually have to reset my vacuum so often. Unloading the vacuum is easy enough, and while it's not exactly a mess, it's not as bad as a canister vacuum because it's not as big and difficult to maneuver. The only problem I've had with almost every vacuum cleaner is the hair getting wrapped around the main roller. It's inevitable given the length of my hair, but I didn't have a hard time clipping the hair from the curlers and brushing it out. The side brushes spin brilliantly, which I wasn't sure about. The "bang" feature that lets him know when to turn is very gentle. My previous robot vacuum crashed into furniture at top speed and made a few dents, but this one doesn't have that problem at all. He pats the furniture and walls gently and turns away, I'm not worried about any damage. My favorite feature of this vacuum cleaner is its quiet operation. In operation, it is about as loud as a box fan at maximum speed. It's not completely silent, but it's almost invisible compared to a conventional vacuum cleaner. I could easily watch TV if it was on the other side of the same room. Overall, I cannot recommend this vacuum cleaner enough. The price is very cheap compared to other vacuum cleaners on the market. This is an amazing vacuum cleaner, quiet, easy to use and able to clean the whole house on a single charge.
