Quite naturally, being an updated, more advanced model, the Roomba 761 is more efficient in dirt and dust removing thanks to several 2-generation technologies, such as:
The other technologies such as scheduling, iAdapt navigation or 3 cleaning modes are the same. The vacuum cleaner comes with Ni-MH battery that needs more time to recharge, but it is safer, as it can be completely discharged. However, thanks to an advanced HEPA filtration system, it eliminates 98% of dirt, pet hair and dust, cleaning the surfaces more efficiently, especially the carpets. Meanwhile, comparing iRobot Roomba 650 vs 761, I would say that the basic model is more reliable, easier to program, more intuitive. It comes with a better display that includes more buttons, but it is quite simple and easy to maintain.
But for the color, both models look virtually the same. A refurbished model of Roomba 650 exists, it comes with a grey core insert, so I wouldn’t even tell the difference. However, the basic model is more lightweight and compact.
Paralleling Roomba 761 vs 650, we see that the basic model is commonly a bit more affordable. Additionally, it is incredibly popular, being simple and reliable. As to the advanced model, customers do love it, but they still complain that it’s hard to navigate and get used to, especially for beginners.
The Roomba 650 model is a budget and basic iRobot vacuum. It is easy to setup and reliable, powerful and feature-rich. The cleaner is programmable and quite intuitive. Additionally, it is lightweight and compact, navigating the rooms pretty well. However, it comes with rotating brushes that are removable, but hair still gets stuck in them.
Putting in comparison iRobot Roomba 761 vs Roomba 650, it’s worth mentioning that the advanced model is more efficient in cleaning thanks to several improved technologies that concern navigation and dirt detection. It eliminates allergens and removes pet hair better than the basic model, being preferable for pet owners and the people that suffer from bronchial asthma and skin allergies. However, the vacuum is a bit more expensive, it is heavy-weight and bulky. Additionally, it is hard to program and navigate and, therefore, not the most popular.
