Why is the little rectangle on the side sucking in so much air and causing it not to work?

Just experienced this "rectangle sucking tons of air" problem with my UV850 Shark - turns out there was not one but two blockages: one in the hose and one in the very base of vacuum (which necessitated using a screwdriver to open the two grey screws on the bottom). Once I got these cleared the vacuum was back to normal.

What is the difference between Shark NV 352 and the NV 356

The 352 has a 25 foot cord, the 356 (professional) is 30', the hard floor tools are different. The 356 has a microfiber 'dust pad' that goes over the hardwood floor attachment. The 352's hard floor attachment has a 'V' shape to funnel debris no pad, but it does have a duster attachment both available to purchase separately. The dust cup on the 356 is larger and the overall machine is 2 lbs heavier then the 352. 356 also comes with a bag for the tools where my 352 did not. The other tools all appear to be the same on both models. They both run the same amps and can be converted into canister mode as well, but are aesthetically different.

How do you clean the filter?

There is a HEPA filter in front of the vacuum, you lift the door from the bottom and you can take it out and wash it. and then you lift the canister out from the base ( like you're emptying the canister of dirt.) You will find 2 foam filters there. lift them both out and wash those too. Just dont throw in washing machine or dishwasher. I use dish detergent and wash them off in the sink. Just make sure they are completely dry before putting them back on the vacuum. After a dozen or so washings they will break down ( you will know this ) extra filters can be purchased on EBay or Amazon or other websites. I usually clean the foam filters when they are a very dark brown or gray color,then i also wash the HEPA filter also. Good luck! Here a PDF file that tells you all about the shark vacuum .Page 13 & 14 tell you how to clean the filters . http://prcind.com/user_manuals/NV351-FS.pdf

Does it pick up paper clips?

My old vacuum picks up paper clips and staples. However, it's not a Shark vacuum. And it's been going since 2005. Maybe Eureka is the way to go :).
