This is a great little pull behind vacuum that is great for hard wood floors, rugs and carpets! Maneuverability It is very easy to turn on sharpe corners and can swivel really well and very quickly. You just point where you want to go and the back end unit has great roller wheels that slide right behind you Ease of Maintenance Let's face it no one likes to clean a vacuum but this one is easier to pull out and dump right into your garbage can. It is a no fuss unit. The filters (there are several that help prevent bulid up overtime of scents) are easy to keep clean. For added scent I place a dryer sheet in the external filer so that we get a fresh scent in the air that lasts for a few days Suction Performance I sucked up my shower curtain with the wand attatchment and pulled the whole thing down on my head, so the suction works great Versatility Does wonderful on my hard woods and on my carpets. Just tap the adjuster with your foot which gives you three different angles the rollers go over to allow for carpet or hardwoods. Design I gave it an 8 only because the 'mouse' is very heavy to lug around behind you. This would never go up stairs as it is a bit heavy to pull around alreary but for a single story it gets the job done the first time around. Durability We have had ours for three years and still haven't even had to change the filters. It really is a great vacuum and we are glad we bought it.
