This is absolutely the best stick vacuum. It surpassed the stratos stick vacuum which is an excellent vacuum also. It is more powerful than even the stratos if that is possible. It has a reconfigured floor head and it stands on its own. The powerdetect on it is great. This vacuum will possibly replace every vacuum cleaner you have ever had. I purchased the shark powerdetect upright and loved it but had to return because of the weight. This vacuum is as powerful as that one and is lightweight. Great Job Shark.
