Irobot sweeping robot is a famous American brand with a history of nearly 30 years. It is also a well-known brand. The new Roomba s9+ has been upgraded in terms of suction, and the suction has been improved, so that Roomba s9+ no longer needs to bypass the carpet. When walking on the carpet, it will automatically turn on the carpet pressurization mode to clean the dirt and debris in the carpet fiber with maximum suction. But at the same time, the suction is large and the noise is relatively large, so you can buy according to your own needs.
Summary: In terms of price, Fina has advantages in cost performance, low noise, strong cleaning ability and strong practicability, but if you want a sweeper with great suction, Irobot is also a good choice.
