Suction power is good, similar to a cordless handheld vacuum. Do not expect miracles from him in this regard, large objects cause him problems. Just like a cordless handheld vacuum, the dust bin fills up quickly, but instead of seeing this, stop vacuuming and throw it in the trash. it will instead just start spreading dust and dirt all over the place. Be sure to clean it before/after each cleaning session. I wish there was a sensor that could alert you when the bin is full. The vacuum cleaner keeps getting stuck in the gap between the floor and cabinets in our kitchen, so I tried setting virtual boundaries with the app to prevent this from happening. Unfortunately, at the time of writing this article, the application is very simple. I like controlling it with my phone, laser mapping, and the ability to build invisible walls so it doesn't fall down the basement stairs or get stuck under the sofa, but that option is very imprecise and you're not exactly where the virtual wall is stands in relation to the actual floor plan. The notifications are a nice feature so I can keep an eye on them from anywhere in the house. I hope he gets an update to add more detail to the mapping system. When the vacuum returns to its base to recharge, it does not rush toward it as expected, but takes its original path, but in the opposite direction. This is a bit strange and seems to be taking longer than it should. Of late he has also started to miss a proper docking with the base, causing him to slip the base and then give up. I recommend using mounting tape to hold it in place. Overall, I'm very impressed with how well it works, even with its quirks, some of which could well be user error. But since the manual is almost non-existent, I don't know who to contact. The novelty of the scissors makes me want to take the time to play with it and learn more, but I don't know if others would be willing to take the time and effort.
