Ease of going from one surface to another; Ease of using wand and tools! Lightweight yet durable; quiet; I recently had a redwood drop through my roof and I had needles etc. all in the bed frame, etc. this sucked it all right up and the little wand could get in between mattress and bed frames. Dog hair and dust are no match.....the little turbo is Fantastic........I am just So pleased with its performance!
