Robot vacuum cleaner: the ultimate guide

Admit it: the robot that cleans the house is a little/big dream! If you are thinking about buying a vacuum cleaner robot, there are some things you need to know. Does it really work? In this article we will answer this and other questions: will it clean well? Will it fall down the stairs? Will it get stuck if it finds an obstacle? What if I have a pet in the house? Let’s clarify the subject once and for all, first trying to understand how they go and the features, and then we will introduce you to the models that have convinced us the most among those now on the market. At robotsnavigator.com you can choose any robot vacuum cleaner you like.

Robot vacuum cleaners: what they are and how they work

Many people say that technologies are increasingly improving our quality of life: in fact, comfortable robot vacuum cleaners can relieve us from the daily cleaning tasks. They are round or square-shaped appliances, no taller than 7 – 8 centimeters, which pass through the house independently, removing unnecessary dirt, in practice the daily dirt.

There are no handles or anything else: these little robots do everything by themselves, even cleaning under the furniture, removing dirt from under the sofa, the bed or in places where it is difficult to arrive with a normal vacuum cleaner.

How they vacuum

The operating principle is similar to that of a normal wireless vacuum cleaner, equipped with a rotating brush. Underneath the machine body there are rotating brushes that collect dirt to vacuum it at the same time. The more brushes are present, the more dirt is collected and sucked in: this is why we suggest you to consider those models that have at least three of them, the right number to obtain a good level of cleaning. Some models are equipped with rubber brushes that prevent the dirt from getting stuck and nesting in them.

Robots are less powerful than a normal vacuum cleaner: that’s why they are good for removing daily dirt, even if by now, almost all models are able to remove from the crumbs, hair to the smallest particles, a detail useful especially for those who suffer from allergies.

How do they move around the house

The vacuum cleaner robots move thanks to small wheels on the back of the product where there are also rotating brushes. Usually, the new range of vacuum cleaner robots is equipped with a camera that allows you to map the house and understand which are the points that have already been cleaned and those where you still need to go.

Finally, thanks to special sensors, robots are able to clean carpets without getting stuck or damaged. Most models use 4 cleaning methods: zig-zag between furniture, toys or bulky objects, spiral for more thorough cleaning, bounce or along the walls to remove dirt from the skirting boards.

Vacuum cleaner control: direct or remote

On navigation, know that most models have two types of settings: the automatic one, to make the robot clean when you are out, and the manual one, to bring it to clean in the areas you want.

In most cases, the automatic settings can also be controlled from your smartphone thanks to the dedicated apps, or by setting them directly on the display at the top of the product, which works a bit like a talking window. Recent models also have the connection with the main Smart Home systems such as Alexa and Google Home.

How to use the vacuum cleaner robot

The use of the robot is very simple, otherwise they would not be called robots! Just be sure to insert the plug of the charging dock where the robot is housed to allow the battery to recharge.

At this point, with the tank empty and the battery at maximum, you can start the vacuum cleaner either through an app or by simply pressing the power button. You can even program and set up daily cleaning sessions up to seven times a week.

How to choose the robotic vacuum cleaner: what to evaluate before buying it

It is difficult to make a real classification of these products because a lot depends also on the type of house you have, i.e. the type of surface you intend to clean and how extensive it is. For example, if you don’t have particular surfaces such as carpeting but only the simple floor, you can opt for simpler and less expensive models, equipped with generic brushes. Another example is if you have a very big house: in this case try to check the capacity of the robot tank. But let’s see in detail the features to evaluate before buying.

Recharge time and battery life

Most models start cleaning from the base and return to it when the battery begins to run out of power so that they can be charged again for a new cleaning session. We like very much the models that after recharging, return to the point where they stopped cleaning due to the low battery: even for large surfaces, they will proceed to a total cleaning, in several sessions.

The battery is therefore not so fundamental to consider. Generally speaking, the average autonomy is around 1 hour and a half, even if the most powerful models can even exceed 2 hours, but with the automatic return to base in case of low battery, the autonomy is virtually always unlimited! In order for the battery to have a good power and autonomy capacity opt for a battery higher than 2500 mAh.

Tank capacity: how often should the tank be emptied?

If anything, one of the limits comes from the capacity of the dirt collection tank. For this reason try to opt for those models that have a tank that can contain at least 600 ml of dust.

Noise level

Check also the noise level: it’s true that the latest generation robots are very quiet, but take a look at this feature too, in order to avoid that your downstairs neighbor will come to sound annoyed.

Robot shape: which is the best one?

Consider also the shape of the robot: if you want them to clean even under the furniture or armchairs, opt for the lower ones that “svirgolano” better between one area and another of the house without getting stuck in contact with the furniture. As for the round or square shape, we think that square ones are better at cleaning in the corners.
