Other brands

In this cheap price range (up to $200), it is very difficult to find a robot vacuum cleaner that can do more than be a ride for your cat. Such models, as a rule, do not have either side brushes or central ones (at low power it is better to have them).

They also have small-sized nickel-metal hydride batteries and some of them cannot return to the base, or even navigate in space, get out of the wires and display error codes (most often there are no displays). As a rule, such models do not have normal outgoing air filters.

In addition, too cheap models have very low suction power (in general, for robotic vacuum cleaners, it is low – from 8–10 to 70–80 air watt). Robots vacuum cleaners with low suction power still somehow work on hard surfaces, but they are useless for carpets.

Although there are some exceptions, such as the Proscenic 820s, If you decide to buy a cheap robot vacuum cleaner from a Chinese company, pay extreme attention to the choice.

Look at the reviews of real customers on Amazon, read reviews, study the company itself and its policies. But remember that even after such a study, you still buy this device at your own risk.

How much is a robot vacuum cleaner?

What features do you need?

When answering what robot vacuum should I buy, the best robot vacuum cleaning assistant, you should pay attention to the following key features:

Dimensions and shape of the robot cleaner

The thinner the robot vacuum cleaner, the easier it is to climb into hard-to-reach places. These smart assistants have a round or semicircular shape, which helps them bypass corners and not touch oncoming objects. Usually, robot vacuum cleaners weigh about two kilograms, the newest models have a height of 6-8 cm.


You can control the assistant vacuum cleaner using the remote control or LCD-display and buttons located on the top panel of the robot. But there are other ways: voice control or a specially defined program. You can also activate the “virtual walls“, which will limit the cleaning area. And intelligent cleaning management is possible using infrared sensors at the bottom of the device, which will not allow the robot vacuum cleaner to fall from the stairs. There are also models that can be controlled through the application for mobile gadgets. It allows you to control the functions of a robot vacuum cleaner at any time from anywhere in the world. Using the application, you can easily configure cleaning modes, manage the schedule and receive notifications about cleaning and maintenance.

Battery life

The larger the cleaning area, the more important how much the vacuum cleaner can run on battery power. For cheap models, it takes 20-40 minutes, more expensive ones have voluminous batteries that can work for several hours. If you are looking for an answer to the question of how to choose a robot vacuum cleaner for a house or a cottage, we definitely recommend choosing a larger battery – because it will have to work longer than in an ordinary apartment.

Possibility of automatic charging

If you have a multi-room apartment, the robot vacuum cleaner will be very handy, which can drive into the dock itself when the battery is close to discharge. After recharging, some devices are able to return to the place where they stopped cleaning, and continue it – for a large area, this is convenient.

Virtual wall function

This is a device that restricts the “entry” of the robot into a certain territory: in another room, in a children’s or work corner, a “place” for the dog, but you can’t always just close the door to them. The way out of this situation is a virtual wall. A “wall” consists of at least two battery-powered units.

Number of cleaning modes

Some robot vacuum cleaners are designed for local cleaning, that is, you can only tidy up such a small area – for example, collect accidentally dropped garbage from the floor. The more cleaning modes, the larger the area and more complex geometry of the room your device will be able to “overpower”. In advanced models, cleaning modes are up to 60.

Building a room map

If things are constantly out of place in your house, then choosing a robot vacuum cleaner with this function means overpaying for unnecessary items. The robot will have to rebuild the map if you scatter shoes, put a grocery bag in the corner, or forget a chair in the middle of the room. So if you feel that your lifestyle is a creative mess, it’s better not to torment a high-tech device, but rather to buy a simpler model with contact navigation – it will go around your scattered things without unnecessary calculations.


It is impossible to foresee everything, and if the robot vacuum cleaner enters an inaccessible corner, he will be able to understand this. And give you a sound signal – so that you come to the rescue, pull it out and adjust the route.

Self Emptying

The trend this year has been a move to models that come with a combined charging and dirt disposal station. While self-emptying robot vacuums used to be super expensive, models such as the Neabot and the Shark IQ, the price is really coming down. It is a great feature as it is surprisingly easy to forget to empty them, especially when you rely on scheduling.
