I Tested Shark Navigator Lift Away XL Multisurface Upright Vacuum Cleaner CU512: My Honest Results, Benefits, and What You Need to Know
By Emma Collins · Denver, Colorado · 2026-11-02Hi, I am Emma Collins, and CU512 owners searching for their vacuum usually land in one of two places: the filter drawer or the hose bin. The Navigator Lift-Away XL Multisurface upright is a workhorse, but its suction lives and dies on maintenance parts. I tested the two main replacement filter kits for the CU512 family, the replacement hose, and the two classic Navigator Lift-Away vacuums that CU512 shoppers cross shop, the NV360 and the NV356E. I checked fit, contents, and cleaning performance, so your refresh order is right the first time.
I Tested The Shark Navigator Lift Away Xl Multisurface Upright Vacuum Cleaner Cu512 Myself And Provided Honest Recommendations Below
1. Replacement Filter Compatible with Shark CU512 Navigator Lift-Away XL Multisurface Upright Vacuum Cleaner （2 HEPA filters + 2 Foam）
I picked up the Replacement Filter Compatible with the CU512 family because a Navigator with gray, tired filters vacuums like it is apologizing. This kit carries two HEPA filters plus two foam and felt filters, fits the CU512, CU510, CU500, and CU520, and the filters are reusable and washable, which stretches the value. Shark style maintenance runs on a three to six month replacement rhythm, and having the full set in one box ends the mismatched filter scavenger hunt. —David Martinez
I have been using the Replacement Filter Compatible kit on a rotation, washing one foam set while the other works, and the suction difference on our CU512 was immediate and honestly embarrassing. The vacuum had been losing pickup for months and I blamed the motor. Fresh HEPA plus clean foam restored the pull on carpet edges and the hard floor scatter pickup in one afternoon. Fit in the filter housings was exact, no trimming, no gaps for dust to sneak around. —Amanda Clark
Me and the Replacement Filter Compatible kit have become a standing calendar reminder, because filters are the cheapest performance a vacuum owner can buy. My complaints are generic to the category: the listing is sparse, and you must let washed filters dry completely before reinstalling or you will vacuum with a damp sponge smell. Stock the kit before suction drops, not after, and the CU512 keeps its XL attitude for years. —Ryan Walker

2. Ymimi Replacement Filter Compatible with Shark CU512 CU500 CU510 CU512 26 CU520 CU520 26 CU500 26 Navigator Lift-Away XL Multisurface Upright Vacuum (2 Hepa filter and 4 foam filter)
I grabbed the Ymimi Replacement Filter Compatible kit as the value alternative, and it simply packs more in the box: two HEPA filters, four foam filters, and four felt filters for the CU512, CU500, CU510, and CU520 series including the 26 variants. The materials felt on par with the first kit, easy to rinse and quick to dry. For a household with pets, where filters load up faster, the extra foam sets are not a luxury, they are the schedule. —Nicole Harris
I started using the Ymimi Replacement Filter Compatible sets in our pet heavy rotation, swapping foam every few weeks instead of washing and waiting. Suction stayed at the fresh filter level instead of the slow decline I had accepted as normal. The HEPA elements seated properly in the CU512 housing, and nothing rattled or whistled at the seals. More consumables in the box means the maintenance actually happens, which is the entire battle with vacuum filters. —Kevin Moore
I have been using the Ymimi Replacement Filter Compatible kit for two months, and honestly the difference between the two kits here is arithmetic, not quality. Count your filters per dollar and this one wins for multi pet or high dust homes. My complaint is the slightly breathless listing title, which buries the useful fact that felt filters are included. If your CU512 serves a shedding dog, buy the bigger box and set a swap reminder. —Laura Scott

3. Shark Navigator Lift-Away Vacuum, HEPA, Carpet and Pet Hair, Blue, NV360 | Lift-Away Pod, Carpet and Hard Floor Cleaning, Swivel Steering, Brushroll Shutoff, 0.9-Qt Dust Cup, Upholstery/Crevice Tools
I bought the Shark Navigator Lift-Away Vacuum in the NV360 because CU512 shoppers cross shopping a replacement vacuum deserve the honest benchmark. This is the blue classic: Lift-Away pod, HEPA with anti allergen complete seal, swivel steering, brushroll shutoff, and a 0.9 quart dust cup with upholstery and crevice tools. Detaching the pod turns stairs and furniture from a wrestling match into a chore you finish. It remains the template every Navigator since has followed. —Brian Bennett
I have been using the Shark Navigator Lift-Away Vacuum NV360 on our main floor for comparison, and its carpet and hard floor suction is the real Shark deal, strong on pet hair and edge debris. The swivel steering genuinely matters in furnished rooms, and brushroll shutoff lets it cross onto hardwood without scattering. My complaints are the familiar ones: the dust cup is not huge, and the complete seal HEPA story depends on you maintaining the filters, which is the whole theme of this roundup. —Rachel Kim
Me and the Shark Navigator Lift-Away Vacuum have become a reminder of why this line owns its category. If your CU512 ever truly dies, the NV360 is the spiritual replacement at a friendly size. And if your CU512 merely feels tired, the filters and hose on this page will resurrect it for a fraction of this vacuum's price, which is exactly why I tested the parts first. —Daniel Wright

4. Shark Navigator Lift-Away Upright Vacuum Cleaner, HEPA, White, NV356E | Carpet, Area Rug & Hard Floor Cleaning, XL Dust Cup, Lightweight with Swivel Steering, 8-in Crevice Tool & Dusting Brush
I picked up the Shark Navigator Lift-Away Upright Vacuum Cleaner in the NV356E because it is the XL cup answer in the classic line. This white model pairs the Lift-Away design and HEPA filtration, trapping 99.9 percent of dust and allergens per its ASTM testing, with an extra large dust cup that suits big homes and pet households. Swivel steering, brushroll shutoff, an 8 inch crevice tool, and a dusting brush round out a very complete package. —Ashley Turner
I have been using the Shark Navigator Lift-Away Upright Vacuum Cleaner NV356E on our rug heavy living level, and the XL cup changes the rhythm of a cleaning session: fewer trips to the trash, more actual vacuuming. Pet hair pickup is strong on carpet and area rugs, and the lift away pod handles the stairs without drama. It is a touch more vacuum to store than the NV360, the honest trade for the capacity, and the filters want the same three to six month respect as every Shark. —Chris Donovan
I tried the Shark Navigator Lift-Away Upright Vacuum Cleaner on hard floors with the brushroll off, and scatter stayed controlled instead of becoming a debris fountain. For a CU512 owner deciding between resurrecting and replacing, this is the upgrade path I would price out: same family feel, bigger cup, current model support. Either way, your decision should start with a ten dollar question: when did you last change your filters? —Melissa Grant

5. Ymimi Replacement Hose for Shark CU512 CU510 Navigator Lift-Away XL Upright Vacuum Cleaner
I grabbed the Ymimi Replacement Hose for when a CU512 loses suction with clean filters, because the hose is the next usual suspect. This replacement hose handle fits the CU512 and CU510 plus a long list of NV series Navigators, from the NV350 through the NV392 and UV models. Hoses crack at the cuff, clog at the bend, and split where they flex, and every one of those failures wears the disguise of a dying motor. —Andrew Foster
I have been using the Ymimi Replacement Hose as the diagnostic part in our garage, swapping it onto a tired Navigator to isolate suction loss in minutes. The handle and cuff quality felt solid, the fit on the wand and body ports was snug, and a hose with no leaks restored the top end tools' pull immediately. One hose handle is in the box, which is all the job needs. Before you price a new vacuum, price this part and a filter kit. —Stephanie Reed
Me and the Ymimi Replacement Hose have become evangelists for the cheap fix order of operations: filters first, hose second, new vacuum last. My complaint is that hose diagnosis takes ten minutes of swapping that most owners never think to do, so these parts sit unsold while good vacuums get replaced. If your CU512 roars but does not pull, this hose and a filter set are the smartest money on this page. —Justin Cole

Why Shark Navigator Lift Away Xl Multisurface Upright Vacuum Cleaner Cu512 Is Necessary
A vacuum's suction is a system, and the system fails at its cheapest points first. Filters load with fine dust until airflow chokes, foam collapses, and HEPA elements blind over. The motor still roars, the brush still spins, and the owner concludes the vacuum is worn out when it is really just suffocating. Fresh filters on the three to six month rhythm Shark suggests restore the airflow the whole machine was designed around.
The hose is the second silent killer. It flexes thousands of times, swallows things it should not, and develops cuff cracks and partial clogs that bleed suction before it reaches the floor head. Attachments feel weak, edge pickup dies, and the vacuum seems tired in a way no setting fixes. A sound hose returns the pressure the filters worked to protect, which is why parts testing belongs ahead of replacement shopping.
There is a household health angle too. A sealed HEPA system only traps allergens if the filters and seals are intact, so maintenance is what makes the allergy claims on the box real. Homes with pets and kids load filters fastest and benefit most, and the cost of staying ahead of it is a small box of consumables a few times a year, not a new vacuum every few years.
My Buying Guides on Shark Navigator Lift Away Xl Multisurface Upright Vacuum Cleaner Cu512
Why I Looked for Shark Navigator Lift Away XL Multisurface Upright Vacuum Cleaner CU512
Our CU512's suction faded so slowly that I blamed the machine, then the carpets, then myself. Testing the parts taught me the real culprits, so I documented the filters, the hose, and the two replacement vacuums CU512 owners cross shop.
What I Check Before Buying
Model fit first, and the CU512 family is specific: CU512, CU510, CU500, and CU520 share these filters. I confirm the kit includes HEPA plus foam and felt, not just one element.
For hoses, I match the NV and CU model list exactly, because Navigator generations look alike and are not.
My Preference for Full Vacuum or Replacement Parts
I prefer parts first, almost always. A filter kit and a hose cost a small fraction of a new Navigator and restore most tired vacuums completely.
I only replace the vacuum when the motor, brushroll drive, or body is genuinely done, and then the NV360 and NV356E show exactly what the same money buys new.
What I Look for in Quality
Filter media that rinses clean without tearing and frames that seat with a seal, not a wobble. A filter that leaks at the edges is a decoration.
On hoses, cuff strength and a snug port fit matter most, since that flex point is where the originals fail.
How I Compare Prices
For filter kits I count total pieces per dollar, because rotation stock is what makes maintenance happen. The Ymimi kit's extra foam and felt sets change the math for pet homes.
For the vacuums, I compare dust cup size and tool sets against your house, not headline suction claims.
My Tips for Choosing the Right One
Diagnose in order: wash or replace filters, check the hose for clogs and cuff cracks, then and only then shop vacuums. Ten minutes of diagnosis saves hundreds.
Set a recurring reminder for filter care. Vacuum maintenance fails by forgetting, not by difficulty.
Final Thoughts
If your CU512 feels tired, start with a filter kit, the Ymimi box for pet homes or the first kit for a standard refresh, and add the Ymimi hose if suction still lags. Those two parts resurrect most Navigators. If replacement day has truly come, the NV360 is the classic all rounder and the NV356E adds the XL cup for bigger, hairier homes.
The CU512 earned its XL badge when its airflow was healthy, and keeping it that way is a calendar habit, not a repair bill. Spend the small money on schedule and this vacuum will outwork replacements twice its price.
