TL;DR
- Dyson V15 Detect — the best handheld vacuum money can buy. Best for deep cleans, hardwood floors, pet hair, and allergy households.
- Shark IQ — a top-rated self-emptying robot. Best for daily maintenance between deep cleans.
- For most homes: buy both. Together they cost less than one flagship Roomba combo and clean significantly better.
Where the Dyson V15 wins
- Laser headlight reveals invisible dust on hardwood floors. Not a gimmick.
- LCD particle counter quantifies what you're picking up by size class — useful for allergy households.
- Among the strongest suction in any cordless, by a meaningful margin.
- Fully sealed HEPA filtration captures the fine particles a cheaper vacuum re-aerosolizes.
- Deep-clean ability: rugs, upholstery, ceiling fans, car interiors — one tool does all of it.
Where the Shark IQ wins
- Self-empty base holds 30+ days of dirt. You think about it monthly, not daily.
- Maps multi-room layouts after one mapping run; clean specific rooms from the app.
- $200 cheaper than the comparable Roomba j7+.
- Genuinely set-and-forget for maintenance days. Schedule it and move on.
- Cleans hard-to-reach floor zones — under furniture, behind the toilet, kid-room corners.
Where the Shark falls short
- No object avoidance. It will hit cords, shoes, and toys. (The j7+ is the upgrade.)
- Loud during dock empty — about 75 dB for 30 seconds.
- Surface-clean only. It can't drive deep into a rug pile.
Where the Dyson falls short
- Battery still tops at about 60 minutes on low (38–45 minutes on Auto).
- 6.8 lb is real weight for ceiling-fan and overhead work.
- $649 is a real price tag.
The right combination
If you have $850–$1,100 budgeted for cleaning, this is the optimal split:
- Dyson V15 Detect ($649) — for the weekly real clean
- Shark IQ ($449) — for daily floor maintenance
Together they cost less than a single iRobot j7+ Combo ($1,099) — and split the work between deep cleaning (Dyson) and daily maintenance (Shark) instead of asking one machine to do both.
Who should buy just one
- Just the Dyson if: You're willing to vacuum weekly yourself, you don't want a robot underfoot, or you live in a small apartment.
- Just the Shark if: You're OK with a slightly-less-deep clean in exchange for zero manual vacuuming most weeks. Best for busy households or rental properties.

FAQ
Is Dyson really better than Shark?+
On suction, build quality, and feature set: yes. On price and self-empty convenience: Shark wins. The right answer depends on whether your priority is the deepest possible clean (Dyson) or hands-off daily maintenance (Shark). Most homes benefit from owning one of each.
Are cordless vacuums as good as plug-in vacuums?+
Flagship cordless models now match or beat plug-in performance on suction. The remaining trade-offs are battery life (35–60 minutes) and dust-bin size, not raw power.
Will a Shark IQ replace my main vacuum?+
No. A robot maintains floors between deep cleans but doesn't do furniture, stairs, or detail work. Plan on a stick vacuum for weekly deep cleaning even if you own a robot.
