This is an excellent manual sweeper. The build quality of this sweeper is superior to those from other brands. It was extremely easy to assemble. This is bigger than the typical "home" model carpet sweepers (some of which cost twice as much). The two cleaning brushes with independent gears maximize pickup. I have not seen this feature in other products. The clear dirt bin makes it easy to know when you need to empty it. This has picked up dust and debris from laminate floors, tile floors, and low pile carpet with ease.
One thing to keep in mind is that the rubber brush rolls may not function well on medium pile carpet (I can attest to this). However, for most commercial applications, this performs extremely well. The corner brushes are a nice addition and add to the functionality of the sweeper.
Overall, this is probably the most effective and well-built manual sweeper that I have owned and I highly recommend it, just be aware of the type of brush roll that is being used here (it does work better on tile floors than the traditional “vacuum style” version).
