Shark Rotator APEX DuoClean Powered Lift-Away Vacuum NV650 NV650W NV651 NV651Q NV652 NV750W NV751 NV752 NV765 NV831 NV835 AX950 AX951 AX952 Filter Set, 1 Hepa + 2 Foam & Felt Filters, XFF650 & XHF650

Everything fit my several years old Shark liftaway perfectly. I should have replaced much sooner, the suction was so much better even though I washed the other filters religiously. I was vacuuming and bumped the front filter cover and it shot off, I was like that's new.........After investigating further I found the pressure was building up behind the filter. Upon inspection with magnification the filter fibers were very worn and restricting airflow as much as the dirt was. The vacuum still had enough suction to pick up what I could see, but most certainly not doing a complete job.For the price, change your filters more regularly, I will be.

I have the Shark Model NV831 the duo. These filters did not work. When i replaced my original filters with these replacement filters my machine lost suction. Will be sending back for a refund.

Sending back! Too small for my shark rotator lift away NV 751. second time I purchased after market filters and the same thing! Hair and dirt gets suctioned around the foam filter and makes the HEPA filter dirty after one use. Ugh!

Attractive, nice size, width for narrow spots. Great suction, Very heavy for me, (a short, old, grandma), hard push forward and to pull backwards.Somewhat clumsy for turning, but GREAT for straight ahead, super deep cleaning. Lift off hose is short but would buy a longer one, if available, as an accessory. I have the under couch/appliance wand which is wonderful. I usually end up using my Bissel stick vac for everyday quick cleaning and my old Kenmore cannister for edges, corners, tight spots, and car cleaning. I would buy this again and put up with the minor nusences, but would like it better if it was self propelled forward and backward even if it cost more. My daughter-in-law has the larger model and she has said it's heavy for her also.

We have two labrador retrievers, and they shed 24/7, but this vacume is up to the task of keeping our floors free of furr and almost anything you don't want on your floor. Works fantastic on hard floors as well as carpet. We have had many vacumes over the years, but this is by far the best one and at a fantastic price.
