Coming from the famous iRobot Corporation, belonging to the advanced, 700 series, the vacuums are evidently very similar. They come with several beneficial technologies, such as:
They are self-charging, having 3 cleaning modes and HEPA filters. The most basic difference is the battery type. The model 761 comes with a Ni-MH battery that is longer to charge, but it has a better life, being able to work longer. The vacuum is quieter and its dustbin is larger, requiring less maintenance. An additional set of HEPA filter is included to the parcel. On the contrary, paralleling iRobot Roomba 770 vs 761, I would draw your attention to the fact that the model 770 is supplied together with extra round and flat brush cleaning tools. It has a beneficial dustbin indicator that is absent in 761 model.
Quite naturally, the vacuums look very similar. Comparing iRobot Roomba 761 vs Roomba 770, we mention the difference is in color, as the model 761 is grey, Roomba 770 is black. Additionally, the advanced device is more lightweight and compact that is important for cleaning difficult to reach places under the furniture.
Commonly, the model 770 is much more expensive, as it’s more popular. Customers like that it’s efficient in dust and dirt collection, smart, powerful and advanced. On the other side, the model 761 has a bit higher rating, being better by price/quality ratio.
Due to several innovative technologies, the vacuum is quite powerful and performant. Thanks to persistent pass feature, it removes 98% of dirt and dust, debris and allergens, pet hair. It comes with the side and motorized brushes, being quite good at navigation. The vacuum is suitable for bare floors, but occasionally gets stuck on rugs and carpets, while the brushes still work well on the carpet’s edges. Unfortunately, the vacuum is not able to clean stairs. However, it’s pretty lightweight and compact in comparison with the other Roomba devices.
Putting into comparison Roomba 761 vs 770, we see that the 761 model is very similar to the previously reviewed model, coming with all the same advanced technologies. It is only longer to recharge and operate due to Ni-MH battery that is considered to be outdated. A dustbin indicator is also absent. Additionally, a great vacuums disadvantage is that it’s heavy-weight and not the most compact. But Roomba 761 still comes with remote control, being smart, easy to use and good in navigation.
