Crevice and grouted-floor pickup has negative customer evidence, especially on grouted tile where grit required repeated passes.

Large-debris hard-floor intake is a weakness because users report thrown particles and litter blowback.

Large-debris hard-floor intake is mixed, with strong customer pellet pickup but CNET criticism that Cheerios were too tall for the head.

Onboard tool storage is a clear convenience when the tools stay accessible and easy to use.

Onboard tool storage is a weakness because the vacuum cannot hold all attachments and tools can fall or require the bag.

Ownership costs are a concern because OEM bags, belts, and optional pet tools add expense.

Ownership costs are favorable where discussed because the vacuum is bagless with washable filters and little routine replacement.

Stair use is limited by weight and lift-handle complaints despite useful step/edge attachments.

Stair cleaning is a consistent benefit because Lift-Away mode and attachments make stairs easier than with a fixed upright.

Maintenance is mixed-to-negative because belts, filters, and brushroll cleaning can require ongoing attention.

Longevity feedback is mixed, ranging from multi-year praise to early belt, hose, motor, and handle failures.

Longevity evidence is mixed-positive, with warranty praise and several long-term owner reports balanced against isolated failures.

Cord management earns praise for simple wrapping and top cord routing, with some wishing for retractability.

Cord management is a downside because the cord is manual, non-retractable, and can get in the way.

Upright stability is a weakness in customer feedback, especially when the pod or wand is used and the unit tips easily.

The forward-propel feel helps some users, but others still miss true self-propelled drive.

The self-propelled feel helps carpet cleaning for many users, though the pull can feel too strong in tight spaces.

Edge and baseboard cleaning gets positive mentions from both the attachment layout and edge-cleaning system.

The headlight is consistently useful in positive feedback, though one reviewer questioned non-LED longevity.

Headlights are strongly praised for showing debris on floors, dark corners, and attachment work.

Under-furniture pickup is favorable when the machine or tools reach beneath furniture well.

Under-furniture pickup is a major advantage because Powered Lift-Away lets the head or wand reach under beds and furniture.

Suction is the strongest recurring praise, with multiple reviewers calling it powerful or excellent.

Reviewers consistently describe the NV752 as a strong-suction corded upright with high airflow, especially through the hose and on carpets.
