Review of the vacuum cleaner robot Roomba 650 (series 600)


Irobot marketed a few months ago the new Roomba 600 to replace the Roomba 500 series of vacuum robot. This comprises of 4 available models: Roomba 620, 630, 650 and 660.

The 600 series is very similar to that of the 500. The 620 is the base model of the Roomba series.

Here are the 3 improvements that have been made in relation to the latest Roomba 500:

  • Aerovac technology: the circulation of air is optimized and the dust tray is filled in a more uniform way
  • A new brush, which assists in improving suction, requiring less strain on a central brush.
  • A new color

The prices start at 300 euros with the Roomba 620, which does work out as the best price/quality ratio for small budget buyers. But at this price it does not mean that you abandon the basic functions; all models in the 600 series will return to their base automatically and recharge their battery, they will have sensors to detect obstacles, and will be able to identify dirty ares in a household. The only drawback is the 620 and 630 do not have a programming function and have less accessories.

The Roomba 650 is most programmable (up to 7 times per week and at specific times!!!) will cost about 358 Euros. The 660 will be identical though sold with more accessories.

We should recall here that another more advanced series already exists, it is the Roomba 700.

The robot is shipped with

  • A database of reloading (identical to that of the series 700)
  • A virtual wall
  • A comb of cleaning
  • 2 Replacement Filters

No remote control with all models of the 600 series.

The 650 model is sold with a virtual wall. Virtual walls create an invisible barrier of maximum 2 meters (cone-shaped) that the Roomba will not to breach. It requires two C batteries (not included).

Here’s is the cotton filter :

From the outside the 600 models are a quasi-certified copy of the 500 series, except for the color. I love the yellow circle which is stylishly married with the black.

There remains the same operation principal, in relation to the buttons as the 500 series. At the top we find the buttons Day, Hour and Minute, which will be used to adjust the clock as well as the programming.

The Clean button activates or stops the robot. The Spot button allows you to launch a cleaning target and the Dock button orders the robot to return to its base.

Finally, at the bottom we have the buttons Schedule and Clock for programming and clock setting.

The clean button can illuminate for 4 colors:

  • Uniform Red: battery empty
  • Flashing orange: Charging in Progress
  • Uniform Green: fully charged (there is no possibility to disable the green light which stays on constantly).
  • Orange Flashing quickly: 16 hours of recharging regeneration required.

To the right, it is written DIRT DETECT which means that the robot is able to identify the dirty places. It uses of audio sensors to detect small particles and clean more in greater depth.

It also has a carrying handle:

The 650 is similar to the 780. The wheels, brushes and the side brush are identical. However, the 780 has two vacuum sensors, which is more than the 650 (under the wheels).

Brushes of the Roomba 650:

Brushes of the Roomba 780 :

In the manual it is recommended to clean the brushes and bearings once a week. An excessive accumulation of dirt or hair could cause permanent damage to the Roomba. This is the case with virtually all vacuum cleaner robots. The only exception is the Neato, whose bearings are well protected and brush hardly retains dirt or hair.

Here is a video of the cleaning and fortifying of brushes:

The dust trap

The dust trap is much more practical to remove than the Roomba 700 series. A simple pressure on the Dust button and the dust tray withdraws. There is no need to enter the robot with your hands.

The inside of the dust tray is equipped with Aerovac technology.

Its capacity is 0.5 L (on average) comparative to 0.8 L for the 700 series.

Operation of the Roomba 650

The Roomba is a vacuum cleaner robot with a random navigation system, meaning it will clean an area serval times in a cycle. It uses a cleaning technology patented by the manufacturer called iAdapat. This technology enables the robot to monitor actively the environment 64 times per second and to react with over 40 different movements.

It has a battery life of 2 hours, which isn’t bad for a robot with random navigation. It takes 3h for a full charge.

Without an intelligent virtual wall I estimated the cleaning capacity is about 60 m2. To properly clean a surface and with its repetition of the cycles in a week, the Roomba will ensure that it cleans everywhere in a household. Another way to separate the surfaces is by closing doors. This will assure the Roomba moves to different locations.

This robot works on most floors: wood, carpet, tile, vinyl and linoleum.

There are 2 cleaning modes :

  • Clean Mode: The Roomba automatically calculates the size of the room and adjusts its cleaning time accordingly.
  • Spot Mode: The Roomba cleans in a spiral over a 1 meter diameter, then starts a new cycle from its point of departure.

The Roomba 650 is programmable each day for up to 7 cleanings per week (one each day). The setting of the clock and the programming are simple! Its designed to be used straight away without too much consultation with the user manual.

The robot can communicate messages and troubles in a dozen languages. The default language of the Roomba is English. It only takes a few seconds to change the language with the help of the manual.

The navigation remains faithful to the previous models. Its iAdapt technology allows it to cover the surface properly every time.

The area in the video above is approximately 30 m2. The Roomba had 1 hour to clean the entire surface. This is only the robot’s estimated cleaning time. Unfortunately, it did not clean everywhere on the surface during the filming of this demonstration, this the disadvantage of the random mode, it may not clean everywhere each cycle. This is the repetition of several cycles in a week which ensures a complete cleaning.

In the video, at 2’15”, it is cleaned up under a chair and then spent nearly 3 minutes stuck there. This is long, but in the end it goes out!

The Roomba can sometimes be a little “Rockstar”. Certainly it slows down before touching an obstacle but unlike other robots it doesn’t stop at a few millimeters. In my experience it can move quite ineffectively when stuck in a room or vacuuming around plants.

Some do not appreciate but there is an advantage with it being able to go behind a curtain or a bed cover.

As with other robots it does have difficulty dectecting dark surfaces or objects of a width of less than 5 cm.

Tests of sugar : record equaled on hard ground !

I reproduced the identical test in order to compare the suction capabilities of each robot vacuum cleaner.

A very nice surprise with this Roomba 650! It has tied equal with the record set by the Neato XV-25 with 78% of the sugar sucked. It is even a result equivalent to that of the Roomba 780 which is supposed to be the most powerful model. It is possible that the two HEPA filters of the 780 are not such a good idea.

On carpet the result is also very positive with 37 grams sucked on the 50 or 74% of the sugar. It is much better that the new brush of the Neato XV-25 which had already recovered 62% ! The bristle brush combined with the brush into strips allow this feat. The repetition of passages in relation to the navigation of the methodical Neato advantage the Roomba for this type of test.

In conclusion

With a score of 14.7 /20, the Roomba 650 misses the head classification from Kelrobot (I must change the scale). Costing 399 euros, it is the vacuum cleaner robot with the best price/quality ratio if compared with other more powerful robots.

I would recommend for medium surfaces not exceeding 60m2 (by level) because unlike the Roomba 780 it does not have virtual walls to help it locate areas to clean.

Note that for and extra 10 euros more you can buy the top model, the Roomba 770 which achieved similar performance to test the sugar on carpets and hard floors but which in addition has been improved (larger dust tray, more sensors and a better autonomy etc).

Whichrobot rating: 14.7/20 (how we rate)

Now you know a little bit more on the Roomba 650. Other tests of robots are in preparation. Be aware that the best way to be kept informed on the publication of new tests is to click i like on our Facebook page.
