A robotic vacuum cleaner can clean the carpet without much assistance from the owner. Most of these machines are about 3.5 inches high, so they can easily reach under furniture.
In cities, dust tends to collect under the furniture. Hence, it is important to choose the right robot vacuum for your home.
The best models are WiFi-enabled and come with lithium-ion batteries for a longer battery life. They also have High-Efficiency Particulate Air (HEPA) filtration to prevent airborne dust.
