I love the light weight and maneuverability of this unit. I had central vac in the last house- would never consider it again after using my Samsung stick vac. Much easier to grab and do a spot cleaning or the whole house. Suction is great, easy to empty the canister as well. I usually do it when the kitchen can is empty so I can put it right into the can as I empty it and keep the dust contained. attachments work well under, around baseboard heaters, furniture,  and especially for the car! this is where the second battery usually comes in for me- vacuuming the car at high power can deplete the battery pretty quickly. The second battery is really handy.
