Buyers switching to Quantum get an all-in-one wet/dry cordless vacuum that ditches HEPA filter replacements entirely — Memorial Day savings are live on the site with free shipping.
REVEAL CODE & SAVE
Your cordless vacuum dies twenty minutes into a full-house clean. The wet spot from your dog’s water bowl sits there because switching machines mid-task feels like defeat. And last time you ordered a “revolutionary” vac online, the battery arrived dead and customer service ghosted you after the third email. Three frustrations, one pattern: most vacuums force you to pick between wet spills and dry debris, and the brands selling them don’t back up their claims.
The Quantum W takes a different approach — water filtration instead of disposable HEPA filters, cordless wet/dry capability in a single unit, and a replaceable battery so the whole machine doesn’t become e-waste when runtime drops. Memorial Day pricing is active on their site right now with free shipping on every order. If you’ve been burned by cordless vacs that overpromise and underdeliver, this one is worth a closer look.
The Verdict: YES, Buy — But Understand What You’re Pre-Ordering
The Quantum W’s water filtration design solves a real problem — no more $30 HEPA replacements every few months, no more dry dust blowing back into the room when you empty the bin. The wet/dry cordless combo in one machine means you’re not juggling a separate mop and vac. But here’s what you need to know: this is a pre-order. Current batch ships June 1–7, and as a newer brand without thousands of Amazon reviews to lean on, you’re betting on the engineering rather than a track record. The 30-day money-back guarantee and free shipping reduce that risk substantially. For $379 with Memorial Day pricing and included detergent, the value proposition holds up — especially against Tineco’s $399 Floor One S5 which still requires filter maintenance.
The Pros:
- Water filtration traps dust in water — no clogged HEPA filters to replace, ever. That eliminates the $30-60/year consumable cost most cordless vacs sneak into the ownership experience.
- Free shipping on all orders and 30-day money-back guarantee remove the two biggest risks of buying a vacuum sight unseen from a newer brand.
- Replaceable battery design means the entire vacuum doesn’t become landfill when runtime eventually degrades — swap the battery and keep going.
- Wet and dry modes in one cordless unit — no switching machines mid-clean when you hit a spill. Detergent included in the box saves you the first accessory purchase.
The Cons & The “Ugly” Truth:
- Pre-order only as of May 2026 — units ship June 1–7. If your current vacuum is fully dead today, you’ll be waiting 2-3 weeks. Not a dealbreaker but plan accordingly.
- Real Talk: Quantum has no established review history on Trustpilot or Amazon yet. The 30-day guarantee is your safety net here — use it if the vacuum doesn’t meet expectations. For a $379 purchase from a newer brand, that guarantee is doing the heavy lifting on trust.
🛡️ Verified by ProductInsight Team | Last Checked:
I went in expecting another direct-to-consumer vacuum brand with slick marketing and a product that underdelivers. The water filtration claim caught my attention — mostly because I’ve spent too much on HEPA replacements for my last three cordless vacs and I’m tired of the racket. Here’s what the Quantum W actually brings: a brushless digital motor paired with a water chamber that traps dust and debris in liquid instead of forcing air through a filter mesh. The replaceable battery is a modular design choice that most brands at this price point avoid — they’d rather sell you a whole new unit in two years. The included 250ml detergent and self-cleaning cycle suggest the engineering team actually thought about the full ownership experience, not just the spec sheet.

Material & Build Quality Analysis
The Quantum W is built on a black and red ABS plastic chassis — the same material grade used by Dyson and Tineco at this price tier. What’s different is what’s inside: water filtration replaces the traditional multi-stage filter stack. Debris and dust get trapped in water, which means what you dump out is a liquid slurry rather than a dry dust cloud. The brushless motor should run quieter and last longer than brushed alternatives common in sub-$300 vacs. The replaceable battery pack is a rare sight in the cordless vacuum world — most manufacturers seal the battery inside, which turns a $50 fix into a $300+ replacement purchase when capacity degrades. The LED display shows mode and battery status, and the self-cleaning cycle automates the post-use maintenance that most people skip until performance drops off a cliff.
Price vs. Quality
At $379, the Quantum W sits squarely in the mid-premium cordless vacuum segment. Tineco’s Floor One S5 runs $399 and still uses traditional filter maintenance. Dyson’s comparable wet/dry options start above $600. The water filtration eliminates the recurring filter cost — at $30-60/year for HEPA replacements on competing models, the Quantum W pays back that difference within two years of ownership. Factor in the free shipping and included detergent, and the initial purchase covers more ground than competitors at similar price points. The trade-off: you’re buying from a newer brand without the warranty infrastructure of a Dyson or the Amazon review volume of a Tineco. The 30-day guarantee is your hedge against that uncertainty.
