Yes, the hoover has a HEPA filter and it can overcome a slope of 15% up to 2 cm. However, I would buy another robot hoover if possible, the Dreame D9 has laser navigation and can find its way around the flat much better. The extra charge is not very high and the Dreame D9 also has a HEPA filter and can overcome thresholds of approx. 2 cm.
