This is the baby I wanted but never got. Three-position power switch. Off, the vacuum motor is on, the vacuum motor and wide roller brush motor are on. Very quiet and the suction power is incredible. Dust doesn't get into the air during use if you don't bother cleaning the filters from time to time. The three-stage switch allows you to vacuum hard floors without a large brush, as well as sensitive surfaces such as carpets. I won't drag him into the video as he doesn't rotate with this shot. Then the third part of the switch uses both motors: a wide brush that rotates the floor, as well as a suction motor. Makes a lot of sense. And as far as I know, this is the only such series. It's great technology and beautiful design. Finally an engine that doesn't stall when the roller is running at full speed. Just keep sucking. There's a joke, but I'll miss it. Really great car. Quiet and very powerful. Love it!
