CHOVERY Robot vacuum cleaner window!

The product arrived in Italy in 15 days. Packed very well with regular mail. The instructions are in English but with QRcode there are in Italian. I found it more convenient to spray the detergent on the glass because on the sponge it ends immediately. It is slow to make a large window takes 12 minutes, it is also as noisy as a vacuum cleaner. But it cleans well and does its job.
