Being not the most basic, but not the most advanced model, Roomba 770 stands out by the other brand vacuums by several beneficial technologies, such as:
Coming with dual HEPA filters, the iRobot vacuum is definitely better in terms of the cleaning performance and efficiency. It eliminates 98% of dirt, dust and pet hair, experiencing virtually no navigation problems. It comes with multi-room navigation system and full-bin indicator, great sensing abilities, being easy-to-maintain, quiet, smart and reliable. ILIFE A4s vs Roomba 770 is weaker in terms of navigation, as its infrared sensor is not suitable for dark flooring and rooms. On the other side, the Chinese vacuum is more powerful, suitable for larger areas cleaning before the dustbin emptying as its very large. The vacuum is simple and reliable, maneuverable, coming with a good battery and several beneficial sensors.
I think, that ILIFE A4s model is a doubtless winner in terms of appearance and design. It is perfectly lightweight and low-profile, fitting the slots under the beds and sofas. The vacuum stands out by minimalistic design and grey color, being amazingly durable and scratch-resistant.
Quite naturally, the budget Chinese model is more affordable. It is listed among the best-selling vacuums, coming with a high rating and a lot of positive reviews. However, some navigation and sensing problems still occur, the device gets stuck sometimes. So, if I had money, I would still opt for the advanced Roomba device due to its great, seamless performance and several innovative features.
