I find they agitate dirt well, though I haven’t tried that many other washer washers.
I started with Unger microfibers when I began my business. I have also tried their “standard” and Monsoon (I use/like their retention ability on certain jobs) sleeves.
I have used Pulex microfiber washers and find that they push certain debris (such as retail clothing store cloth lint) around to my frustration. I also use Pulex MicroTigers on certain accounts, but at times dislike the added drag across the glass they provide.
I just received some Ettore Porcupines last night in an order from Tom at Supply.
Can you offer some product reviews – I’m open to trying new (to me) products.
