With the advancement of technology, robot vacuum cleaners are no longer a surprise to most of us. It has become common to find a robot mop or vacuum in more households than ever before.
And that is mainly because as the years pass, the older models go down in price, making them affordable. In an iRobot roomba761 vs. 650 comparisons, we are going to review and discuss two of these considerably older models. We also have a iRobot Roomba 761 vs. 620 comparison, which you can check out after this.
From physical appearance to technical and technological features, the roomba 761 and 650 have some significant differences between them that separate them from each other and the rest. So let's jump right in!
iRobot Roomba 761 Review
If you are looking for a mid-range robot cleaner with a convenient remote control function, then you can't miss this. With the remote, you can control the power and stop or resume it as you like.
But that is not all! It has a 3 Stage Cleaning System. This patented feature helps to clean every corner and edges around the room for debris. Its brushes do a great job of picking them up from different surfaces and bringing it near the suction.
However, probably its most featured feature is the Dirt Detect sensors. As the name says it all, it senses around for dirt and debris and alerts the device to keep cleaning that area for more.
Besides, it doesn't need any programming to do. Just pressing the "CLEAN" button at the front starts the process, and it will begin vacuuming around the house until it runs out of battery life.
Being a mid-range robot cleaner, it is in the middle for weight and dimension as well. The unit weighs about 14.6 pounds or 6.6 kg, which is still relatively lightweight. And it measures 21.5 inches in length, 19 inches in width, and 5.6 inches in height.
Moreover, its set of intelligent sensors help to guide it around and under all the furniture for deep cleaning of the floor. It is mainly suitable for hardwood floors, tiles, and cleaning carpets.
Lastly, its battery can typically last up to 2 hours, managing more than one cycle. The lithium-polymer battery when low on battery, the unit returns to its home base charging station automatically.
iRobot Roomba 650 Review
A more high-end model with some excellent technological features, the 650 is a great option if you want an advanced robot cleaner and willing to spend more for it. Its most prominent feature is considerably the scheduling.
It allows you to schedule cleaning up to 7 times a week, which means you can program it every day to vacuum while you are asleep or doing something else. You can also do it manually pressing the “CLEAN” button to clean any area.
Besides, it has its patented 3 Stage Cleaning System. So it ensures thorough deep cleaning of your carpets, corners, and edges of the rooms, different floors, etc. It can also adjust to different floor types like tile, laminate, hardwood, carpeted, and more. It is one of the best robot vacuums for laminate floors.
Moreover, thanks to its small 3.6-inch height, it can reach under most furniture. Its specific design for the purpose provides an even thorough cleaning getting into every place of your house. Their goal is to ensure dirt has no place to hide.
The unit measures around 13.4 inches in length, 13.4 inches in width, and 3.6 inches in height. Along with that, it weighs just 7.9 pounds or 3.5 kg, making it very lightweight and portable.
Another of its advanced feature is the iAdapt Navigation. This helpful technology uses a set of different sensors in order to navigate around the house. It senses any object or wall and slows down immediately without bumping into them.
When it comes to batteries, it uses a lithium-ion battery that can help to clean continuously up to 2 hours before draining its battery. It does automatically go to the charging station and takes about two and a half to 3 hours for a full charge from low.
iRobot Roomba 761 vs. 650 Comparison
Some of the differences are clear, but let us give you a more detailed and distinctive view of the two.
The 650 is a lot smaller and compact compared to the 761. It is 13.4 inches in length, 13.4 inches in width, and 3.6 inches in height; this gives it a much better advantage to get under furniture for a thorough cleaning.
On the other hand, the 761 is quite big in terms of dimension, measuring 21.5 inches in length, 19 inches in width, and 5.6 inches in height. This makes it not the most portable, but it is rarely a problem for a home cleaner, however.
As you can already guess, after the difference in dimensions, 761 is heavier than 650 by a significant 6.7 pounds or 3.1 kg! The 761 model is 14.6 pounds or 6.6 kilograms, which is quite heavy for a robot cleaner but not quite an issue.
The 650, on the other hand, is only 7.9 pounds or 3.5 kg. It thus adds to its portable and compact quality.
Dust Bin Capacity
One thing we didn't really touch on in our review is their dust bin capacity. They both have a moderate-sized bin to store the debris and dirt, but it needs cleaning after each cycle is complete.
The 761 has a dust bin capacity of 0.5 liters, whereas the 650 has a capacity of 0.47 liters. While yes, the 761 has a larger compartment than 650, it is not a revolutionary difference, but maybe it could mean something to you or others.
Battery and Power
The 761 Roomba uses a lithium polymer or Ni-MH battery, which charges faster, taking 3 hours or less. On the other hand, the 650 uses a lithium-ion or Li-ion battery that takes about 4 hours or more to charge fully. But, both last 3 hours maximum on a full charge.
However, when it comes to power, the 650 is a more powerful unit of 33 watts. And the 761 has 30 watts power. So it gives the 650 a better suctioning power than 761.
