The metal center piece does not fit (regardless of how you try to assemble/disassemble). As far as the vacuum cleaner itself, using the attachments, it is fantastic for picking up fine, small dog hair! Instruction manual should be colored other than just "black and pic" for those of us with eyesight deficiencies.
We are hard on vacuum cleaners in out home, with almost half a dozen pets, and nearly as many outdoor-working men traipsing around, and I am pleased with the Shark NV42 Navigator. We'd had virtually every brand of vacuum die prematurely in our home, even the pricey ones starting with K, D, and M. We'd been gifted a previous model Shark Navigator, and it proved serviceable for about four years before a main hose to the unit suffered a cut or tear, and research proved repairing the old unit would have been pricier than a new purchase. The "new" model arrived (was sold as Refurbished at a good discount) looking pristine and shiny in the box. Being familiar with the old one's configuration, it was a literal snap to assemble. It works well on multiple surfaces and not to much seems changed from the older (purple) model we'd had. There are just a couple of quirks, one being the on-board tool storage. This unit comes with what the manual calls a Pet Tool, which is a small head attachment framed in a sort of velvety fabric that you see on lint brushes sometimes. I couldn't see where this tool could store on the machine, and the manual does state and show the storage spots for the other attachment tools, but not this one, This is also not the most lightweight machine (which mostly comes into play on stairways), nor does it have swiveling movement, which some buyers may be looking for. Overall, it is proving to be a good dependable machine, but without some of the high-tech goodies that some buyers might prefer.
I got pretty tired of stepping on kitty litter so this was a Christmas present to self. It helped that on the Overstock card it qualified for 0% for 6 months. It has pretty good traction and I find it pushes a wheeled chair around and various other little things around my apartment, definitely an improvement over the one I bought when these robo vacs first came out, even pushed around the self-feeding water dish that holds a fair amount. I've tried Gorilla 2-sided tape under small area rugs and found that after a while even the Gorilla tape wasn't keeping rugs attached to vinyl flooring. I also find that it sometimes sucks up smaller area rugs, gets stuck, and shuts off. I finally bought a wooden riser using Gorilla tape to secure it to the floor, which has ended the water and food dish being pushed around. It is needy. You really do need to do the weekly maintenance. It came with a round of "disposables" and I've since looked on the manufacturer's website for replacement parts, which are a bit more than expected. The HEPA filter is nice and I take an upright vacuum cleaner to it periodically to clean it, doesn't seem like it would stand up to cleaning with water. I'm also not convinced the mopping function is all that practical, still use a Swiffer weekly, but vinyl flooring is definitely much cleaner. It takes people and cat fur well and there is definitely a lack of killer furballs in my apartment now; however, I find an impressive layer of cat fur collects under the HEPA filter. I have long hair that continues to fall, which does get twisted around rollers and has to be loosened around wheels oftentimes with tweezers and scissors. I'm pretty happy with this contraption, just wish replacement parts weren't so pricey.
