This attachment was purchased for use with the My Shop Vac. I like the fact that the hole has a small gap at the bottom. It sucks much better than my vacuum cleaner. It's great for cleaning concrete floors as it picks up sand and dirt much better than the Shop Vac. The only complaint about the material the nozzle is made of. The plastic is very hard and smooth, unlike the material used in the wand of a vacuum cleaner. When cleaning, the nozzle often slips off the end of the extension tube. That sucks, otherwise I would have given 5 stars.
