Shark PowerDetect Speed Cordless Stick Vacuum vs Shark PowerDetect Speed Cordless Vacuum

Both are the same PowerDetect Speed stick, but B adds a self-emptying dock that stores and recharges the vacuum and dumps the bin for you. A is the lighter, simpler version with no dock to place. Reviewers praise the suction detection, attachments and headlights on both, but some find the detect mode annoying and report a sticky power button and a dust bin that does not always seal. Buy A if you want the core vacuum with less to set up; buy B if emptying the bin by hand is the chore you want gone.

• Choose the Shark PowerDetect Speed if you want the same cleaning power without a dock taking up floor space and you don't mind emptying a small bin yourself.
• Choose the Shark PowerDetect Speed Clean & Empty if you want the vacuum to empty itself into a dock and you have room to park it.
