Like any appliance, cordless vacuums require regular maintenance to run at their optimal performance. Most users only tap out the bin and clean the filter, but actually, dust and hair build up in the floorhead shroud, limiting performance.
This is the part covering the rotating brushroll. It's one of the first parts of the vacuum to come into contact with dust and dirt, and it needs to be unobstructed for air to flow through freely. If left uncleaned, accumulated dust will drastically reduce suction power.
