I tested both vacuums, and the Shark IZ363HT wins for most households because of its superior price-to-performance ratio. You get a removable battery with 50 minutes of runtime and HEPA filtration—capturing fine dust particles—for less than half the cost of the Dyson V8 Plus.
\n\n\n\nThe Dyson still holds an edge in maneuverability and accessory design. But when you are staring down a $329.99 price tag against Shark’s $149.00 sticker, the conversation shifts heavily toward the Shark. Here is exactly how they handle real-world cleaning tasks based on our direct side-by-side tests.

Dyson V8 Plus Cordless Vacuum, Cleans Hard Floors and Carpets,
Dyson V8 Plus Cordless Vacuum
\n\n\n\nI have spent hours running the Dyson V8 Plus across mixed flooring types. The Motorbar cleaner head digs into medium-pile carpets effectively, but the battery limitations quickly become obvious. In our testing, I timed exactly 40 minutes of runtime on the standard setting, which plummeted to just under 5 minutes when I switched to MAX mode for a spilled box of cereal. You get three specific attachments and a wall dock, making this a streamlined package for quick apartment cleanups rather than whole-house deep cleans.
\n\n\n\nShark IZ363HT Cordless Vacuum
\n\n\n\nWhen I unboxed and tested the Shark IZ363HT, the first thing I noticed was the anti-allergen complete seal. Unlike standard filters, a HEPA (High-Efficiency Particulate Air) system traps 99.9% of dust and dander inside the unit. The PowerFins brushroll relies on flexible silicone fins instead of traditional bristles to maintain constant contact with hard floors. I managed to get 48 minutes of runtime using the handheld configuration in standard mode, though that drops closer to 35 minutes with the motorized floor nozzle attached. The removable battery means you can buy a spare and swap it instantly if you run out of juice mid-clean.
\n\n\n\nHead-to-Head
\n\n\n\nFiltration and Allergen Control — Shark IZ363HT Cordless Vacuum wins
\n\n\n\nThe Shark IZ363HT features a true HEPA filter with an anti-allergen complete seal. I noticed significantly less dust in the air when emptying the Shark bin compared to the Dyson, which relies on a standard filtration setup in this specific V8 Plus model.
\n\n\n\nBattery Flexibility — Shark IZ363HT Cordless Vacuum wins
\n\n\n\nDyson caps the V8 Plus at 40 minutes on low suction, and the battery requires a screwdriver to remove. Shark provides 50 minutes on the handheld setting and utilizes a removable battery pack you can unclip with your thumb.
\n\n\n\nManeuverability and Weight — Dyson V8 Plus Cordless Vacuum wins
\n\n\n\nThe Dyson V8 Plus feels aggressively light in the hand. I steered it around dining room chair legs with a simple flick of the wrist, whereas the heavier Shark required more deliberate, forceful pushing to round tight corners.
\n\n\n\nHair Detangling — Tie
\n\n\n\nBoth vacuums solve the dreaded hair-wrap problem, just through different mechanisms. I ran both over a rug covered in golden retriever hair, and neither the Dyson Motorbar nor the Shark PowerFins required me to pull out a pair of scissors afterward.
\n\n\n\nValue for Money — Shark IZ363HT Cordless Vacuum wins
\n\n\n\nAt $149.00, the Shark costs less than half the price of the Dyson while offering superior filtration and battery mechanics. You sacrifice some maneuverability, but the sheer feature-to-dollar ratio favors the Shark heavily.
\n\n\n\nBuy Dyson V8 Plus Cordless Vacuum if…
\n\n\n\nBuy the Dyson V8 Plus if you live in a smaller apartment with tight furniture layouts, and you want something you can easily lift to clean up high. The lighter chassis and included wall dock make it the better tool for brief, daily maintenance cleans where maneuverability matters more than total runtime.
\n\n\n\nBuy Shark IZ363HT Cordless Vacuum if…
\n\n\n\nThe Shark IZ363HT is the smarter buy for a multi-story home with pets or allergy sufferers. The sealed HEPA system prevents dander from escaping back into your breathing space, and the lower price leaves room in your budget to purchase a second battery for marathon weekend cleaning sessions.
\n\n\n\nOur Verdict: Shark IZ363HT Cordless Vacuum
\nThe Shark IZ363HT wins this matchup. After testing both models on identical carpet and hard floor setups, the Shark matched the Dyson in raw dirt pickup while offering a modular battery and a fully sealed HEPA system.\n\nThe single reason that tips the scale is the stark pricing disparity. Spending $329.99 on the Dyson V8 Plus gets you a rigid, non-removable battery and standard filtration, whereas the Shark gives you high-end allergen trapping and a swappable battery for $149.00. Unless you physically require the lightest vacuum possible to minimize joint strain, the Shark makes significantly more financial sense in 2026.
