The suction power may not be as strong compared to other Dyson vacuum cleaners (or other brands' full-size ones) I have previously used but it is strong enough to collect fine dust, cracker bits, bits of cat litter, pieces of string and things like that. However, sucking a whole piece of tissue paper or lumps of wet food will not be possible. I even managed to get rid of a wasp that somehow got into my bedroom using this Dyson Omni-glide. My family finds this to be a perfect tool to clean our beds, making them more comfortable to sleep on (with better hygiene). Since the dust container is transparent, it reveals what it has sucked up and I was amazed and mortified at the same time how much fine dust there was on my bed. What I saw was quite a lot of is grey powdery dust being sucked up daily. No wonder my daughters sneeze a lot. Dyson claims that it can capture 99.99% of particles as small as 0.3 microns.
