Had a shark for about three weeks now first time robot vac owner, my daughter has an older model shark. I thought this was going to be a five star review but it is only going to be about a three we have noticed that even with the AI shark definitely has a habit of running into furniture pretty hard I would think with the new technology that it will do it’s best to avoid the furniture but it seems to hit tables chairs sometimes corners of the walls pretty hard. The self container does not hold 30 days if you have pets I’ve emptied my container twice in three weeks. We have had the shark shut down due to dog hair wrapping around the brushes underneath causing it to stop this is something about pet owners will have to clean on a regular basis most likely every other or every third cycle. So today it truly not satisfied but I’ll see how she goes.
