Amazing robot helper
Color: White
I’ve been using this robot vacuum for about a month now, and I have no regrets about buying it! It’s noticeably quieter than my previous robot vacuum, and the mopping performance is excellent. I really like that it has two large water tanks—one for clean water and one for dirty—which makes a big difference as it easily covers my entire house on a single run. I don’t have carpet, so I can’t speak to how it performs there, but for vacuuming and mopping tile and hard floors, it absolutely deserves high praise. The battery is another big plus—it can clean my whole house before needing to return to the base to recharge. The app is fantastic. The mapping is very accurate, and there are plenty of cleaning options to customize different areas of the house. The initial app setup did require some help, but customer support was quick and very helpful. Overall, I’m a very satisfied customer and would definitely recommend it!

Very great and durable option.
Style: for Saros 10R / Saros 20 / Qrevo CurvX
These parts are the perfect option when maintaining your robot vacuum. They fit the machine perfectly and are just as if not more durable than the company provided parts. Definitely recommended.
