Durability. In order to make the cut, dish scrubbers should be able to withstand several months of usage before replacement is necessary. Scrubbers that last only days or weeks will simply not cut it, and will likely end up costing you more money in the long run.
Design. The quality and performance of a scrubber depends largely on its design. A well-designed scrubber is a joy to use, and makes your work almost seem easy. A poorly-designed scrubber, on the other hand, makes even the simplest task a chore – so much so that you almost dread the thought of using it.
Effectiveness. When it comes down to it, the effectiveness of a dish scrubber is what matters first and foremost. A dish scrubber that doesn’t do what is expected of it is pretty much useless, and really not worth spending time and money on.
Weight. Although not quite a dealbreaker, the weight of a scrubber warrants some consideration as well. To be highly effective, a scrubber should be light enough to handle easily, and yet have a nice heft that makes it feel more secure and more robust.
Flexibility. The best scrubbers should be able to handle a fairly broad range of tasks. Apart from cleaning dishes effectively, it should also be able to clean other kitchenware, countertops, and other kitchen items that may need cleaning.
