How to Compare Roomba Cleaning Performance on Carpets & Hardwood?
With regular vacuums, cleaning performance is mostly related to suction power. But, with vacuum robots, suction power is not the only characteristic to impact cleaning performance. In the following we discuss all the features that make a Roomba good at cleaning different kinds of floors: hardwood, tiles, linoleum, or carpets.
– Main Brush System
Most vacuum robots have a main brush underneath to loosen dirt and make it easier to suck. All Roomba do have a main brush system, made of two brushes. These are counter rotating brushes to maximize dust and hair pick up. Besides, some Roomba can adjust the height of their main brush system to adapt to the type of floor they are cleaning. So, for better performance, best Roomba raise the brushes on hardwood floors, and lower them on carpets.
– Edge Cleaning
Because Roomba are round, their main brush cannot collect dirt at the edges. Side brushes compensate by allowing Roomba to reach most dust and hair strands that are often located near walls and at corners.
– Dirt Sensor
It makes Roomba detect dirtiest spots, and spend more time cleaning them. Advanced combo-sensors are better than basic ones. They combine acoustics and optics to better detect dirt.
– Filter Type
