The Roomba 645 can automatically adjust itself to any kind of floor. Whether carpet, hardwood, or tile, it adjusts its brushes to effectively clean the floor. It uses a patented 3 stage cleaning system to agitate dirt and get it deep out of carpets. It uses AeroVac tech to create maximum airflow and suck up as much debris as possible. It has a special function to deal with hair so that it does not get clogged. It’s a good choice for homes with pets. The brushes are very long lasting, which is a big bonus.
Also, the dust bin included here is very large, which is ideal because it does not have to be emptied so often. The iAdapt navigation technology utilized here helps the Roomba 645 navigate your home with ease. It does a fairly good job at avoiding drops and obstacles, while finding the areas that need to be cleaned. It actually does a pretty thorough job at cleaning rooms, plus it is pretty efficient too.
All you need to do is press the “clean” button to set it into motion. When the battery life runs out, the Roomba 645 will go back to its dock on its own to recharge. It also comes with a virtual wall barrier so you can block off a space, keeping it either in or out a certain room until it is done cleaning.
The Roomba 650 is the slightly newer and more modern version of the Roomba 645. Now, instead of listing all the things which are the same about these two models, we want to list all of the differences. To be exact, the Roomba 650 comes with many of the same features as the Roomba 645, with a few improvements made. This is why we aren’t going to repeat all of the same features as the Roomba 645, but we definitely want to talk about why it is different.
One of the big differences between the two is that the Roomba 650 has a much better battery than the 645. While both have the same runtime on a single charge, the Roomba 650 has a longer lifetime overall. The battery in the Roomba 650 will last for close to twice as long as the 645 before it needs to be replaced.
Another big difference between the two models is that the Roomba 650 comes with scheduling capabilities. You can schedule it to clean up to 7 times per week on its own. This is a crucial feature which the Roomba 645 is missing. The Roomba 650 also has a side brush for walls and corners, just like the 645, but it is much easier to remove and maintain than on the Roomba 645.
On the other hand, the Roomba 645 does come with 2 extra cleaning brushes, but the Roomba 650 only comes with 1 extra cleaning brush. Other than that, both of these robotic vacuums are more or less the same. Both have great 3 stage cleaning capabilities, a lot of suction power, they both work well for all floor types, and they do great with pet hair too.
Conclusion
When it comes to the Roomba 645 vs 650 debate, both are great in their own rate. One thing that does need to be mentioned is that the Roomba 650 is almost twice as expensive, but it does have some upgraded features that make it worth the investment.
