Update: After almost two months of use, I now understand that the characteristics of the blade are something more than the point at which the motor for Neato spins the blade. , which deals damage to Neato. I'm not sure if this item can be replaced with Neato. Can't recommend, this set is worth the money. The blade is not 100% flush with the blade cap but works well. I really think the shape does the job better than the regular straight blade. The filters also work just as well as Neato's factory filters. Edge spinners and a cleaning brush are also nice additions. I will buy it again when we use the filters and blade.
