Powered by a 2,600mAh Li-ion battery, this Kyvol Cybovac D3 Robot Vacuum Cleaner provides strong suction of up to 1,800Pa to lift embedded dirt and stain with ease and 60dB noise level. It has 3 cleaning modes to meet different cleaning needs. It works with the Kyvol App. You can set no-go areas by boundary strips and it will cleverly avoid that field while cleaning. It also has an auto carpet boost, meaning it automatically increases its suction to suck out the dirt deep inside carpets. D3 is able to work continuously for as long as 2 hours, perfect for cleaning large rooms of up to 120 to 150sqm without stopping.
