I replaced my old Ridgid wet/dry vac with this newer and more improved one. It does all of the things my old one did but has a lot more attachments which make it much easier to vacuum up large, small and medium sized things. This is a great wet /dry vac very reasonably priced. I bought mine at Home Depot. Maneuverability As is with most wet/vacs, it's on wheels and rolls around pretty good in the garage, shop and flat surfaces. When you are on a slope, it will roll so you need something to keep that from happening. Ease of Maintenance It's very easy to clean and the filter comes right out which is no problem at all to clean and replace. Suction Performance This vacuum really has amazing suction. I have to be careful when I vacuum the leaves out of the rock bed because it will pick up the rocks as well. Not small ones either. Versatility I guess if you could mount it on your back it would be ideal for me. It's a little bit clumsy pulling it around on a slope but otherwise it's fine. Design The design is pretty much standard as with most of these Wet/dry vacuums. They are very easy to use. Durability I had my last Ridgid 6 years and used it a lot. It was still working when I gave to it to a good friend.
