Are you tired of vacuuming your home or office all the time? A robot vacuum might be the solution you need. They offer automatic and efficient cleaning with minimal input from the user. If you are interested in purchasing one, you may be wondering, “What robot vacuum should I buy?” In this article, we will guide you through the process of selecting the best robot vacuum for your needs by answering some essential questions.

Why Do You Need a Robot Vacuum?

Robot vacuums are ideal for homeowners or office workers who don’t have time to vacuum regularly or may have mobility issues. Robot vacuums can also be programmed to clean on a daily schedule, meaning you don’t have to think about vacuuming again. Suppose allergies are an issue for you. In that case, some robot vacuums have high-efficiency particulate air (HEPA) filters, capable of trapping and removing microscopic pollutants from the air.

Tip: Keep an eye out for virtual wall technology that prevents your robot vacuum from entering certain rooms or specific areas through magnetic strips or other means.

What Features Should You Consider When Choosing a Robot Vacuum?

Size and Shape

The size and shape of the robot vacuum are crucial, especially if your house or office has challenging spaces to navigate. Some robot vacuums have spaces no greater than 3.5 inches high and 12.2 inches wide, making it perfect for moving around small places. Others have a D-shaped build for better corner cleaning.

Tip: Choose the size and shape that suits the space you want to clean.

Cleaning Ability

The cleaning ability of a robot vacuum mostly depends on the suction power, which is measured in Pascals (Pa). A higher suction power means better cleaning. Some robot vacuums have a carpet boost mode that adjusts suction power when moving from a hard surface to a carpeted one. Robot vacuums with mopping ability have water tanks for wet cleaning.

Tip: Prioritize suction power when choosing a robot vacuum.

Robot vacuums use different navigation technologies, like cameras, sensors, lasers, or a combination thereof, to navigate around the cleaning area while avoiding obstacles. Some even map the cleaning area for more efficient cleaning.

Tip: Choose navigation that suits your home or office environment.

Battery Life and Charging Time

All robot vacuums have rechargeable batteries that can last up to several hours. Choose a robot vacuum with a longer battery life if you have a larger space. An average charging time takes three hours but can vary, with some taking up to six hours.

Tip: Prioritize battery life and short charging time when choosing a robot vacuum.

App Connectivity

Some robot vacuums come with apps that allow you to control and customize cleaning schedules and pathways from your smartphone.

Tip: Check for app connectivity when choosing a robot vacuum.
