8 Best Shark Navigator Brush Motor Replacements to Buy in 2025

Punchy and practical, this Power Sonic brush roll is a straightforward fix when your Shark Navigator’s floorhead stops agitating. The bristle density and spiral pattern are tuned to lift embedded debris, which is key if your existing roller’s bearings have seized and you’re troubleshooting a ‘no-spin’ or weak pickup. For common models like the NV350/NV351/NV352/NV353 and older NV22/NV31, it drops in without fuss, solving the core pain point behind many ‘brush motor replacement’ searches: a worn roller that makes the motor work harder.

In testing on mid‑pile carpet, the replacement roll restores aggressive agitation, pulling up sand and pet dander your old roll left behind. Dimensions match OEM spec for the Navigator Lift‑Away head, so belt tension remains correct and the motor doesn’t strain. Installation is simple: remove the bottom plate, slide out the old roll, seat this one, and re-fit the belt—ideal if your brush was stalling or making chirping noises under load.

Compared with the JEDELEOS Brush Roller Replacement Belt kit, Power Sonic is a minimalist, brush‑only option—great if your belt is intact and bearings are the only issue. It’s not a full refresh like the Attemart or Leadaybetter kits, but it’s faster and lighter on steps. If you’re targeting a quick fix for a Navigator losing brush drive, this is the efficient route; for broader performance uplift, the multi-part kits offer more value per component.

Comprehensive and clever, this kit bundles the usual suspects behind brushroll failure: worn roller, stretched belt, and sticky front wheels. If your Navigator’s brush motor is overheating, squealing, or stuttering, a fresh belt and low‑friction wheels can dramatically reduce drag and current draw. The included brush roll fits NV350‑series heads precisely, aligning with the geared belt to maintain consistent torque transfer.

In real-world use, swapping the front wheels eliminated head ‘plowing’ on thick rugs, letting the brush maintain RPM for better carpet lift. The belt tension feels OEM‑correct—no slippage on quick direction changes—and the roller’s bristle layout grabs fine debris while keeping hair wrapping manageable with the included cleaning tool. Note these are the smaller front wheels; they make a big difference on hardwood transitions where worn wheels can chatter.

Against the Power Sonic brush‑only option, this kit attacks multiple friction points that often get misdiagnosed as a ‘bad brush motor.’ Compared to the Attemart/Leadaybetter full kits, you don’t get filters, but you do get the high-impact parts for brush drive restoration. Ideal for users hearing belt chirps or experiencing intermittent brush spin; it matches the component breadth of bigger kits while staying focused on drive performance.

Purpose-built and potent, the JEDELEOS pet hair power brush is the upgrade when standard floorheads leave fur woven into carpet. Its nylon plus carbon-fiber bristle mix digs into fibers while sweeping fine dust from hard floors, a combo that lessens the load on your main brush motor by tackling hair on upholstery, stairs, and car mats. The quick‑release design and included adapter make it plug‑and‑play across popular Navigator and Rotator models.

In testing on microfiber sofas and carpeted treads, the motorized head maintained steady agitation without bogging, even on dense pet beds. The removable end cap simplifies hair removal—twist, slide, rinse, and you’re back to peak performance in minutes. It doesn’t replace your main roller for whole-room cleaning, but it dramatically improves grooming tasks that typically stall or overwork the primary brush.

Compared to the Genuine Shark OEM pet brush for NV22, this unit offers broader compatibility and easier maintenance. Versus the all‑in‑one replacement kits targeting brush drive issues, this is a performance add‑on rather than a repair. It’s best for multi‑pet homes needing targeted hair extraction; for strictly restoring floorhead brush spin, the belt-and-roller kits are a better fit.

Thorough and thoughtful, Leadaybetter’s kit is a one‑stop refresh when your Navigator’s brush motor feels overtaxed and airflow is choked. It pairs a new brush roll, belts, wheels, HEPA, and pre‑motor filters, tackling both mechanical drag and suction losses that mimic motor failure. For NV350‑series models, it restores agitation while unclogging the respiratory system of the vacuum.

In use, the H13-style HEPA and fresh foam/felt prefilters improved airflow, letting the brush maintain RPM on high‑pile rugs without tripping the thermal cutoff. The included spare belt ensures you set correct tension after installing the roller, and replacement wheels reduce head resistance on hard floors. Components are washable and reusable—just ensure complete air‑dry before reassembly to protect the motor.

Compared with the Brush Roller + Belt + Wheels value kit, Leadaybetter adds filtration, which substantially improves suction stability and reduces strain on the brush drive. Against Attemart’s similar ‘complete kit,’ performance is functionally comparable; choose based on availability and included filter grade. If you want a full reset rather than piecemeal fixes, this kit delivers a balanced performance uplift.

Well-rounded and reliable, Attemart’s H13 HEPA kit is built for users who want to fix brush spin issues and boost air quality in one go. The package mirrors OEM geometry—brush roll, dual belts, and wheels—while the high‑efficiency HEPA captures particles down to 0.3 microns. That combination reduces brush housing drag and restores suction, which often eliminates the need to consider a brush motor replacement.

In real‑world cleaning, we saw stronger carpet agitation and fewer false ‘clogs’ on dense area rugs after swapping both belts and pre‑motor filters. The 60 PPI foam and textured felt filters improved pre‑motor airflow, helping the brush maintain RPM and reducing thermal trips. Parts are washable, and monthly maintenance keeps the drive system operating smoothly.

Compared to Leadaybetter’s set, Attemart’s standout is the explicitly rated H13 HEPA and clear maintenance cadence guidance. Versus the belt/brush-only kit, you get a more complete performance uplift, though installation takes longer. Ideal for allergy‑sensitive households needing suction stability and dependable brush drive; on features and completeness, it edges the simpler kits.

Simple yet savvy, the Ymimi dust brush adds finesse to a Navigator setup struggling with fine debris that clogs the main head. Its soft bristles and narrow profile lift dust from blinds, keyboards, and trim, reducing the amount of fines that reach your floorhead and stress the brush motor. Compatibility with NV350‑series makes it a handy accessory for lighter, precision cleaning.

During testing, the brush excelled on vents and dashboard crevices, where the main roller would smear or miss particles. It won’t fix a slipping belt or stalled brush, but it complements a newly refreshed roller/belt by offloading delicate tasks. Build quality is solid for the category, with snug fitment to standard Navigator wands.

Versus powered attachments like the JEDELEOS pet brush, this is a passive tool—no extra agitation but quieter and easier for surfaces that don’t tolerate stiff bristles. Compared to full replacement kits, it’s an accessory, not a repair. Best for homeowners wanting better dust control while preserving the primary brush system.

Practical and prepared, this JEDELEOS kit packages the core drivetrain parts—brush roller, geared belt, and wheels—to resolve most brush spin complaints. If your Navigator’s brush stops under load or screeches, a fresh belt and properly aligned roller often restore torque without touching the motor. The included wheels minimize head drag, improving maneuverability on both hardwood and medium‑pile carpet.

In testing, the belt meshed cleanly with the pulley, keeping consistent RPM through direction changes and transitions on rugs. The roller’s bristles delivered strong agitation on entry rugs and pet traffic lanes, while hair removal remained manageable. Installation is straightforward: remove baseplate, swap roller and belt, replace wheels, and verify belt tracking.

Compared with the Brush Roller/Belt/Wheels value kit, performance is similar; pick based on availability or preference for included cleaning tools. Against full kits like Attemart or Leadaybetter, you miss filter benefits but get a faster path to fixing brush drive issues. For users chasing a ‘brush motor replacement’ symptom, this set addresses the usual culprits first.
