So I decided to get a new applicator sleeve and was all ready to buy another microfibre one from unger when I thought I'd check out some other brands. There were a few but the ettore porcupine sleeve caught my eye. It was a bit different because of all the monofilament bristles all over the sleeve. When I got the sleeve I was out straight away with it and the first job was a new customer so the windows were filthy, I could not believe how well this sleeve scrubbed the window, took hard bird poo off effortlessly, and all the other stubborn little marks you come across it handled these just as well, much better than my old unger one. The porcupine made my days work a lot quicker just due to the scrubbing power. Another thing I found with this sleeve is that I wasn't having to dip in my bucket as much, it held a good amount of water but without completely soaking the windows, I found this again was very handy. It also works vey nicely if you want to give the frames and sills a good scrub to, handy when you get bird poo on the sill or something. I did wonder whether a lack of a scrubbing pad at the end of the sleeve would be a let down but it wasn't, the bristles cover the whole sleeve and you can still use the end as a scrubber if you wish. I'd also say this sleeve was lighter to than my previous unger one, and that's once it's dipped in the bucket, not that they are particularly heavy, but any weight saving is a plus in my opinion! I bought the sleeve for £8.55+vat from the window clean centre and its worth every penny!! Seriously recommended if any of you guys fancy a change or need a new sleeve!!
