As the large hassle-free roller brush moves forward, it vacuums, mops and cleans the floor all at once, leaving the floor looking fresh and shiny after just one go. An integrated fan separates water and air so that dirt doesn't get into the ventilator, even when the whole device is completely flat. Reach into spaces as short as 12cm to clean constraint-free under sofas, beds, tables and chairs, covering more ground surface. The increased circumference of the large hassle-free roller brush means that pet hair up to 25cm long is less likely to get tangled, eliminating the need to clean the brush by hands.
