Bought a Bosch from B&Q as they were reduced and selling them off, thought great, I will go for something of quality, brass fitments etc, had a third off it and still cost over £200. It lasted about six months with little hard use when the auto stop failed and it wouldn't shut off when not being used. Got it fixed with no issues under warranty but not what I expected.
It has been fine since, so may have been just bad luck. I also use a decent cleaner like muck off but far cheaper - Nielson Premium - Non Costic - Very important! Fine on everything!
Just lightly wet your bike with jet wash, spray over with the degreaser and rinse off - Simples! It must do a good job as I often get comments passed on how good n clean it looks.
Buy the best you can afford and a tub of Nielson, it will last you years, good on your car / house windows / tiles etc......... Multi use - love it!
