    Your MJ pump vacuum attachment is fantastic. I had been looking for something small like this to vacuum my sump out. I was considering using a shop vac. Thank goodness I found this product. Is is small an when attached to a hose, it is highly maneuverable and fits into tight areas.

    Great product!!!
