With the Ecovac Deebot N78 you will no longer have to worry about hoovering, using the remote you are able to programme the robot to start when you want it to meaning you don't even need to be there. So you can go to work & by the time you get home the hoovering will be done. The Deebot is able to recognise when an obstruction is in its way & it will stop turn & start a different route for cleaning. It also has a sensor which will stop it falling down any steps or stairs, when the sensor recognises a step it will simply reverse & start a new route. The Deebot N78 is perfect for households with pets, it uses direct suction so human & pet hair is vacuumed up directly into the dust bin removing the annoying tangles of hair. If you decide that your floor needs more than a hoover then look no further as the N78 not only hoovers & sweeps but it also mops too. Simply attach the washable microfibre cloth to the optional water reservoir & it will sweep, hoover, mop & dry in one simple pass. If the Ecovac Deebot is running low on battery it will automatically return to its charging dock for a full recharge. If you have had enough of hoovering then the Deebot N78 really is the perfect for you, it makes manual hoovering a thing of the past.
