The difference between the Li-Ion and Ni-Mh battery is a core of the iRobot Roomba 860 vs iRobot Roomba 761 opposition. The working and charging time make a difference. Meanwhile, many working parameters of these two middle-level robotic vacuums match.
The smart vacuums feature the same cleaning area handled, in accordance with their specifications. Roomba 860 gets over larger areas more thoroughly not losing the connection with the docking station and following the scheduled program.
Roomba 761 emits the non-intrusive noise while working. It can be compared to the backstage TV noise versus the louder “advertisement block” of Roomba 860. Still, both robots beat any non-smart vacuum cleaner for this parameter.
Roomba 860 deals with the carpets of different thickness and material — once it gets at them. Sometimes, the robot’s sensors take a particularly thick carpet as a furniture object and don’t let it go further. There is no such problem to compare in Roomba 761, though it does not show as impressive cleaning results when doing the carpets.
The iRobot Roomba 860 is better robot vacuum in this comparison. Check iRobot Roomba 860 price
