I purchased this vacuum after we had a major pipe breakage in our home that left us with an entire nights worth of water standing in three rooms of our home. I choose this unit due to it's large size capacity. The vacuum work with a very high efficiency and helped to eliminate the mess in just a matter of a couple of hours. I had to empty it a few times but that is a very easy task. I also noticed after just a few minutes the unit did pick up the water a little slower, but still worked well enough to do the job. I have no real complaint about the slowing of the unit as in my case I may have very well abused the little vacuum, but it still did a fine job. I would most certainly buy another one if I needed to as I was very happy with the result and the work it saved me. I will have to admit I never expected it to be as loud as it is but that again is a small discomfort to deal with compared to my original mess. This is a really good vacuum for the price and I would recommend it to anyone seeking a wet and dry vacuum.
