Tips for choosing a vacuum cleaner robot : The 9 golden rules to respect

0 comment

Vacuum cleaners robots are beginning to attract a strong interest from many major brands. It is now to the point that we are seeing a multitude of models each year, all with many features and different characteristics. Not always obvious to find …

To help you make your choice, we have designed for you the 9 golden rules to take into account before purchasing a vacuum cleaner robot.


1] Type of navigation on the basis of area

We can differentiate between two types of vacuum cleaners robots: those who move through a room with more or less intelligent yet random navigation, and those who methodically navigate and know exactly where to go, while becoming familiar with the configuration of your home.

For the vacuum cleaners robots with methodical navigation (NeatoHom bot, …), there is an autonomy of 1h to 1h40. In 1 hour, your robot will clean approximately 100sq. m in a cycle. However, it is an average estimate because if your room is congested or if you have carpet and/or rugs, your vacuum cleaner will use more battery power.

Most of these robots have the advantage of returning to their base alone for loading when they are mid course and low on battery, after this they are able to resume their work from where they have left! Some are even capable of performing this operation twice consecutively and thus can cover the surfaces up to 250 m2. But attention! At this rate, the battery will wear faster …

The advantage of this type of navigation is that the cleaning time is faster with the assurance that the robot cleans everywhere.

For the vacuum cleaners with random navigation (as Roomba)They have an autonomy of one to three hours, depending on the models. A robot with random navigation is able to effectively cover a surface up to 60m² approximately (variable with the intelligence of the robot). The disadvantage of this navigation is that the robot will take more time to clean a surface compared to the robots with methodical navigation.

For areas beyond 60m², this type of navigation there is only one choice, the Roomba 780 thanks to its virtual walls intelligent and its algorithm for advanced navigation.

Golden Rule 1: Consider the type of navigation as a function of the area.

2] The decibels

There is no miracle. A vacuum cleaner robot will produce the same noise, but considerably less than a regular vacuum cleaner. The best options at the moment (Roomba and Neato) are not necessarily very discrete either. However a vacuum cleaner robot is supposed to be autonomous and must be able to function in your absence; the choice of a silent vacuum cleaner is only necessary if you intend it to operate in your presence. In this case, you should be aware that it can possible to follow a television program if the vacuum cleaner is operating at 60DBS.

Golden Rule 2: Choose a vacuum robot that is intended to operate in your presence or absence.

3] The bars of threshold and height of carpet

On average, a vacuum cleaner can overcome obstacles of 1.5 cm in height ; which is more than enough for the bars of thresholds and carpet. But attention, a lot of vacuum cleaners are not capable to do this.

Golden Rule 3: Measure the height of your thresholds and carpet.

4] The maintenance of bearings, and the central brush

Overall, a vacuum cleaner robot requires minimal maintenance. Empty the dust trap, check the wear of parts and maintain the brushes. This last task is very important because in each use, hairs and fluff are ensconced in the bristles and must be removed for efficient cleaning. Some robots are easier than others to maintain. The brushes contain hairs that require a more regular maintenance regime than other brushes that consist of laminated plastic. Access to the brush can sometimes be difficult. The maintenance time can vary from 5 minutes to a few seconds per week.

Golden Rule 4: Estimate the time that you are prepared to devote to your robot’s maintenance.

5] The capacity of the drust trap

The dust trays have a capacity ranging of 0.4 l to 2.04 l for those who possess an additional tank at their base (Deepoo D76 and Navibot 8980). For large surfaces or people with animals it is wise to pay particular attention and to choose a robot with enough room in your dust tray.

Golden Rule 5: Choose a Robot with a larger tray if you have animals, children etc..

6] Programming

Nothing more pleasant than to come back to a clean house! A luxury that most vacuum cleaners offer thanks to their system of programming.

Several types of schedules exist: programming delayed, unique programming (same time each day) or different programming each day.

Golden Rule 6: Choose the robot that can be programmed to your needs.

7] Handling obstacles

Vacuum cleaner robots have detectors that help them avoid obstacles. But they do not all have the same delicacy or efficiency.

Some will stop a few millimeters before making contact with an obstacle, where as others will make contact yet slow down before. All have difficulties seeing obstacles (such as a chair) but this does not in any way diminish their work. Some robots are provided with a virtual wall or a magnetic strip which prevent approaching a particular area. This helps to protect the fragile objects or areas not intended for cleaning.

Note: A lot of robots get stuck on these types of stools:

pied chaises

Golden Rule 7: Tailor your robot choice to how you want the obstacles in your home managed.

8] The height of fourniture

It may happen that the height of your furniture is identical to that of the robot, this can be an issue if your robot becomes lodged under you furniture every time its put to use. However this criterion should have little influence in your choice, as you have several possibilities to remedy them. Either you elevate your furniture, use virtual walls, or magnetic tape to prevent it from going below furniture and getting stuck.

Golden Rule 8: Measure the height of your furniture.

9] The hepa filter

Are you subject to allergies? Choose models with HEPA filters then! These filter microscopic particles with fineness and allow the cleaning of dust particles up to 0.3 microns. Thus allowing a larger sanitation of your cleaning area and the removal of allergens. For a better efficiency, do not forget to clean and change your filter regularly.

Golden Rule 9: Adopt these HEPA filters if you are allergic to dust
