The Dreame D9 is mostly similar to the F9 size, 35cm x 35cm x10cm.

Other key hardware features of the Dreame D9 includes:
4 levels of suction mode with up to 3,000Pa of suction power.
5,200mAh battery for up to 2.5hours of operation time; and extended further when combined with “Smart Top-up” function. This feature enables the Dreame D9 to top-up for more power during a cleaning session; and continue the clean when the appropriate level of battery is reached.
