Just a heads up the rod for the wheels may come package in on the wand attachments, to protect it during transit. Also I recommend using a 5/8" or 15mm socket to hold the cap to lock the wheel to the rod.
I used this for about 30minutes to pick up some standing water that was outside, that would not go away. The suction on this was great as it filled up very quickly. This picked up water and a bunch of leaves. For wet applications I removed the filter I love that there is a screw cap on the bottom plug the water. Simply unscrewing it releases the water. The attachments have a tab which latches them to each other, this worked well as it did not fall off while I used it.
This lost a star from me because of the handles, the handles to me, are to slim and not that strong, when I used the handle to tip it so I can roll It when it was filled with water, it felt like they could not support the weight and were not sturdy enough so support the force I applied to it. I was able to get it on the 2nd try , but they handle just feels weak which lowered the score in my eyes.
Locking the top is simple, you can simply twist it on, and there are two tabs on the side that it will latch too. The cord wraps around the handle on the top which is very convenient.
Ridgid has the new 9.0ah batteries, the tools that could benefit from it the most does not fit it. I would love to see an Octane Cordless shop vac. It was a hassle filling this up outside, unplugging it from my generator , stashing my generator, as I was out in the open, and dumping the water and repeating the process. Also I would change the cap screw. It was a pain trying to put it on without a socket to hold it place, as I did not have one handy. For the attaching it, you can use a 15mm or a 5/8" socket. I had to reattach the cap after it fell off and it was a lot easier with the socket to hold it.
Easy to Clean, Easy to Use, Nice Design
the handle could have been stronger
