Roomba 645 vs 650: Comparison And Review

Since both models come from the same series, it’s totally understandable they have many things in common. Let’s figure out how these two models differ and see what they have to offer.

The Design

In my opinion, both Roomba 655 and 650 designs are attractive and elegant with the similar canister. Because they both are the same design of canister shape, they are good choices for cleaning upholsteries like beds, sofas and so on. The Roomba 650 takes after the black color of most Roombas available in the market, while the Roomba 645 gives you an alternative with its gray color.

The Portability

As the weight of both Roomba 645 and 650 is quite low, it has no problem for users to carry these vacuum cleaners upstairs. That weight is acceptable for portability and convenience for users to move it and clean anywhere. Most Roomba model designs are following the style of minimalistic series, which allow you slide itself around house especially into hard-to-reach spots at ease.

The Cleaning Performance

This is the most concerned criteria when it comes to vacuum cleaners. There are many things which will come to customers’ mind before they purchase a product. For example, they may wonder whether it works well on their floor or not; what features it has to be worth that price, etc. Well, here is the answer for you.

The Features :

  • To begin with, both Roomba 645 vs 650 are random robotic vacuum cleaners that can maximize cleaning performance. The powerful 3-Stage Cleaning System with Edge-Sweeping Brush is designed to loosen, lift and suction dust from all types of floor. 3-Stage Cleaning System plays an important role in perfect cleaning performance as it can clean tiles, carpets, rugs, hardwood and more.
  • One factor that makes the Roomba 645 and 650 desirable is the auto-docking feature. When the battery runs low, it makes sure that the machine will get full recharge.

The Difference :

  • The iRobot Roomba 645 has NO on-board scheduling whereas the 650 features the On-Board Scheduling that allows you to set the time for Roomba to clean whenever you want. With a Roomba 650, you can schedule it to clean up to 7 times per week on its own. This is a crucial feature that 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.
  • One of the big differences between the two is that the Roomba 650 has a much better battery than the 645. The iRobot 645 uses the Xlife Extended Life Battery while the 650 comes with the Advanced Power System battery. 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 almost twice as long as the 645 before it needs to be replaced.
  • Moreover, the dust bin in Roomba 645 is very large, which is ideal because it does not have to be emptied so often. The iAdapt navigation technology enables the Roomba 645 navigate your home with ease. It delivers excellent performance at avoiding drops and obstacles, while finding the areas that need to be cleaned. Also, Roomba 645 has a special function to deal with hair so that it does not get clogged. The robot’s longer-lasting brushes allow the Roomba  645 to handle fibers such as hair more effectively, making maintenance quicker and easier than before. It’s really a good choice for homes with pets.
  • Unfortunately, Roomba 650 has hard time determining which spots require more or less cleaning. The navigation system of Roomba 650 isn’t as advanced as the Roomba 980. So it is necessary to place the Virtual Walls effectively to reduce the numbers of missed spots.

The Accessories

The Roomba 645 comes with 2 brush cleaning tools ( 1 round and 1 flat), while the Roomba 650 comes with only the flat brush cleaning tool. The brushes of Roomba 645 are very long lasting, which is a big bonus. The Roomba 645 uses a new easy to remove side brush that has a flat head screw while the Roomba 650 uses the brush with a crosshead screw.

The Price

The criterion I would like to compare Roomba 645 vs 650 is the price tag. The price of Roomba 650 is considerably higher than that of Roomba. While the price of Roomba 650 is approximate $400 whereas the Roomba 645 only costs more than $320.
