Please '' Mr. Ecovacs' invent quickly as practical robot and with the same quality but do both sides simultaneously. Here we would be thrilled !!!
Be careful if you go to the fairs, there is a company that sells Winbot very expensive and it is only the 730 they present you as the 'Rolls' robots. To sweeten the pill, they will '' offer '' a bunch of largely included in the final price accessories, it borders the scam.
To summarize, the WINBOT 930 is a great robot that I recommend without worry.
