I am a little shocked by this vacuum cleaner, in a pleasant shock) The device turned out to be very stylish and incredibly effective - the next day after the usual vacuum cleaner we collected half a container of dust ! I was very pleased with the automatic operation, when he himself begins to harder when he hits the mat ! Cool theme with illuminated crevice nozzle! And finally - a removable battery - this is what will prolong the life of this mega-cool vacuum cleaner for many years ! )) PS: we use roborock s6max as a daily one - it also turned out to be a mega-cool device, we wanted to take a vertical roborock h7, but after reading about the problems with the h6 on, we decided not to risk it and take the T30 with a removable battery! DEFINITELY RECOMMEND!
