I had high hopes for this vacuum cleaner. I assumed that with a powerful engine it could do any job, but it leaves more dirt in its wake than it picks up. You have to constantly walk over the same area as it seems like it takes effort to carefully collect all the dust and dirt on the outer flared edges of the mallet shaft. The extra large whisk feels useless and reduces suction power. Even dirt in the middle of the impact wave is difficult to vacuum up.
