Quick Answer: The Shark CarpetXpert (EX151) posted the highest overall score of any machine in Vacuum Wars’ 2026 carpet cleaner test batch — 73.78 against a 52.51 category average — driven by strong stain removal (90.1 vs. an 83.5 average). But that headline number hides two real weak spots: its sealed hose suction scored 58, below the category’s 65 average, and Consumer Reports’ free category verdict rates its noise only “fair.” Price is $199.99 as of September 2026, discounted from a $249.99 list price at both Home Depot and Shark’s own site. It’s a strong stain-removal pick, not an across-the-board winner.
Last updated: September 19, 2026 — re-verified pricing directly against Home Depot and SharkNinja.com: both now list the EX151 at $199.99 (down from $249.99), closing the $50 retailer gap noted at original publication.
This site’s Shark vs Bissell and Shark vs Hoover comparisons already lean on the EX151’s Vacuum Wars score to make their case for Shark. Here’s what that score actually breaks down to, what Consumer Reports says for free before its paywall kicks in, and a branding detail worth confirming before you buy the wrong SKU.
CarpetXpert EX151, by the numbers
- 73.78 overall Vacuum Wars score (52.51 category average) — the highest of any Shark or Bissell machine in that 2026 test batch, per Vacuum Wars’ published component scores.
- 90.1 stain-removal score vs. an 83.5 average, tested with a standardized 10mL grape-juice stain on white carpet, dried 24 hours, then 4 timed passes and scored by colorimeter — the number behind the EX151’s reputation.
- 58 sealed hose suction vs. a 65 average — Vacuum Wars’ one below-average component score for this machine, easy to miss if you only quote the 73.78 headline.
- 5-year limited warranty, confirmed on both SharkNinja’s own product page and its Home Depot listing — longer than the 1-2 year warranties common on budget uprights this site has reviewed.
What’s good
| Strength | Why it matters |
|---|---|
| 90.1 stain-removal score (Vacuum Wars) | Well above the 83.5 category average on a standardized grape-juice test — the machine's real strength |
| "Excellent" cleaning, "very good" solution removal (Consumer Reports) | Confirms Vacuum Wars' result from a second independent tester, using CR's own free category-verdict excerpt |
| 12.4 kPa floor-head suction vs. 7.26 kPa average | Strong dry pickup on the floor tool specifically, separate from the weaker hose-suction number below |
| 5-year limited warranty | Longer coverage than most budget and mid-tier uprights on this site |
What’s not
- Sealed hose suction is actually below average. Vacuum Wars measured 58 against a 65 category average — the one metric where the EX151 loses to the field, easy to miss behind the strong 73.78 headline score.
- Consumer Reports rates its noise only “fair.” CR’s free category verdict explicitly notes hearing protection may help — a real tradeoff most marketing copy for this machine doesn’t mention.
- Leaking is the most repeated complaint. Multiple retailer reviews describe dirty water spraying from the side vents during use; one reviewer reported the issue recurring across five replacement units. Not universal — at least one independent tester reported no leaking during a full test cycle — but frequent enough to check your unit early.
- The retailer price gap has closed, but check for the sale. Home Depot and Shark.com both now list the EX151 at $199.99, down from $249.99 — a real discount, not a permanent price, so confirm the sale is still active before assuming it’s the going rate.

Who should buy it
Buy the CarpetXpert EX151 if stain removal is your top priority and you’re comparing it against Shark’s own pricier flagships — Vacuum Wars’ testing shows it out-scoring Shark’s own $249.99+ EX304 on overall performance, and its 5-year warranty beats most machines in this price range. It’s also a reasonable pick if you’ve compared it directly against Bissell or Hoover in our Shark vs Bissell or Shark vs Hoover breakdowns and want the higher-scoring machine.
Skip it if hose suction on stairs or upholstery is your main use case — the 58-vs-65 below-average hose score is a real tradeoff — or if quiet operation matters in your home, given Consumer Reports’ “fair” noise rating.

The bottom line
The Shark CarpetXpert EX151 earns its 73.78 Vacuum Wars score honestly — its 90.1 stain-removal result is a real, independently tested strength, not marketing copy. But the same test data shows a below-average hose-suction score, and Consumer Reports separately flags it as only “fair” on noise, so the headline number doesn’t tell the whole story. Confirm which SKU you’re buying, too: the true dual-chemistry StainStriker pretreater is tied most explicitly to the step-up EX201, not this model — and it’s the EX201, not the EX151, that appears in Consumer Reports’ current top picks (see our full Consumer Reports carpet cleaner guide for the breakdown).
