The Shark CarpetXpert EX151 delivers strong suction performance, particularly at the nozzle, and offers easy maintenance with accessible brushroll and cleaning components. However, it performs poorly on certain stains like peanut butter and tomato sauce. The small dirty water tank limits coverage area, though it does feature a convenient hose storage system and integrated spot cleaning tool that enhances versatility compared to competitors. This model is best suited for users seeking a budget-friendly option with good suction but may not meet expectations for heavy-duty stain removal.

Performance Metrics
Consumer Reports rated the Shark CarpetXpert EX151 with a 4.2/5 score, highlighting its strong suction capabilities and ease of maintenance. However, its performance in stain cleaning was mixed, with the EX151 scoring 90.1 in stain removal, which was above average, but falling short in handling tomato sauce and peanut butter stains, which required more than 10 passes to clean. The device's moisture extraction was average, with readings of 27% after 10 passes and 25% after additional dry passes, indicating it effectively extracts moisture but not significantly better than competitors.
Vacuum Wars measured the EX151's unsealed suction at 12.4, which is well above the category average, and its stain removal score of 90.1 placed it near the top of their testing. The device's ability to clean chocolate stains faster than average, requiring only 7 passes for ice cream and 6 for chocolate syrup, was noted as a strength. However, it struggled with more challenging stains like peanut butter and tomato sauce, leaving behind darker stains than average after 10 passes. The EX151's performance in the upright stain test showed that while it excelled in some areas, it underperformed in others, particularly with sticky and oily substances. This mixed performance reflects the device's balance between affordability and functionality, where premium features are traded off for cost savings.
Design and Build Quality
The Shark CarpetXpert EX151 weighs 15.9 pounds, making it lighter than the average 20-pound category, which enhances maneuverability. The device features a 25-foot cord and a 5-foot hose, which is shorter than the average 6-foot hose length. The built-in hose system allows for easy spot cleaning without additional setup, storing the hose on the cleaner itself. The device includes three attachments: a 3.5 reversible bristle tool, an integrated crevice tool, and a 7 wide-path tool, which adds versatility. The brushroll is highly accessible and easily removable for cleaning, and the dirty water tank has two filters, which is more than most competitors. However, the small 0.6-gallon clean water tank and 28-ounce dirty water tank capacity limit the area coverage, requiring frequent refills and emptying during large cleaning sessions.
Consumer Analysis noted that the EX151's design includes a convenient hose storage system and an integrated spot cleaning tool, making transitions from upright to spot cleaning simple. The device's lightweight nature and ergonomic design contribute to ease of use, particularly for users who may struggle with heavier models. The plastic compartment covering the brushroll pops open for easy access, and the brushroll itself removes easily without requiring a screwdriver. The inclusion of two filters in the dirty water tank, while adding to the cleaning process, also ensures better filtration of debris. The overall build quality and accessibility features make the EX151 user-friendly, though the small water tank capacity and short hose length may be limiting factors for some users.
What Reviewers Loved
Reviewers consistently praised the Shark CarpetXpert EX151 for its strong suction performance and ease of maintenance. Consumer Reports highlighted the device's above-average suction at the nozzle, measuring 3.35 nits, which is well above the average of 1.89 nits. The EX151's ability to clean chocolate stains faster than average, requiring only 7 passes for ice cream and 6 for chocolate syrup, was noted as a significant strength. The device's automatic soap and water dispensing when pushed forward and automatic extraction maximization when pulled back were also appreciated, as these features simplify the cleaning process. Vacuum Wars emphasized the device's lightweight design, weighing just 15.9 pounds, which is easier to maneuver than most in its class, and its convenient built-in hose system for spot cleaning, stairs, and upholstery without extra setup.
Hint of Helen, who used the EX151 for six months, appreciated its simple operation and thorough cleaning. She noted that the machine effectively removes dirt and grime, leaving carpets smelling clean and fresh. The 'deep clean' mode, which disperses water when pushed forward and vacuums it back when pulled, was particularly satisfying. The 'dry only' mode, which helps dry carpets further, was also a useful feature. The device's ability to handle carpets and rugs effectively, combined with its ease of storage, made it a favorite for regular use. The inclusion of three attachments – a reversible bristle tool, integrated crevice tool, and wide-path tool – added to its versatility. The device's performance in cleaning sofas and headboards was also noted, although it required more manual effort compared to the upright cleaning mode.
Where It Falls Short
Despite its strengths, the Shark CarpetXpert EX151 has notable shortcomings that impact its overall performance. Consumer Analysis pointed out that the device's dirty water tank has an exceptionally low capacity of 28 ounces, which limits the area coverage before needing to empty the tank. The small 0.6-gallon clean water tank also requires frequent refills during large cleaning sessions, interrupting longer cleaning tasks. The 5-foot hose is shorter than average, limiting reach for stairs or above-floor cleaning. Additionally, the sealed hose suction tested slightly below average, which may affect performance in edge-case scenarios. The device's performance in cleaning tomato sauce and peanut butter stains was below average, with the EX151 leaving behind darker stains than typical after 10 passes.
Vacuum Wars also noted that the 0.6-gallon tank capacity requires frequent refills on larger jobs, and the 5-foot hose is shorter than average, limiting reach. The device's sealed hose suction was below average, which could affect some edge-case scenarios. The frequent refills on large jobs interrupt longer cleaning sessions, and the short hose length may be a limitation for users who need to clean stairs or high areas. The device's performance in handling sticky and oily stains like peanut butter and tomato sauce was subpar, leaving behind darker stains than average after 10 passes. These limitations make the EX151 less suitable for large or complex cleaning tasks.
Who It's Best For
The Shark CarpetXpert EX151 is best suited for users who prioritize strong cleaning performance and ease of use over premium features and large tank capacities. It is ideal for households with moderate-sized carpets and rugs that require regular deep cleaning. The device's lightweight design and built-in hose system make it particularly suitable for users who need to clean stairs, upholstery, and spot areas without additional setup. The EX151 is also a good choice for users who value the convenience of automatic soap and water dispensing and automatic extraction maximization. However, it may not be ideal for users with large homes or those who frequently tackle large or complex cleaning tasks, as the small tank capacity and short hose length can interrupt longer cleaning sessions.
Hint of Helen's review indicates that the EX151 is best for users who want a reliable, easy-to-use carpet cleaner for regular maintenance and spot cleaning. It is particularly suited for households with young children and pets, where quick and effective cleaning is essential. The device's performance in cleaning carpets and rugs was excellent, but its limitations in handling large or complex cleaning tasks make it less ideal for users who require extensive cleaning capabilities. The EX151 is also a good fit for users who appreciate the convenience of a built-in hose system and do not mind the need for frequent refills and emptying of the water tanks.
How It Compares to Alternatives
The Shark CarpetXpert EX151 stands out among competitors for its balance of performance and value. Consumer Reports gave it a 4.2/5 score, which is higher than many mid-tier models, particularly in suction and maintenance. The device's ability to clean chocolate stains faster than average and its strong unsealed suction at the nozzle, measuring 3.35 nits, were noted as significant advantages. However, its performance in cleaning tomato sauce and peanut butter stains was below average, which is a drawback compared to higher-end models. The EX151's small water tank capacity and short hose length are also limitations compared to competitors with larger tanks and longer hoses. Vacuum Wars ranked the EX151 in the top three among tested carpet cleaners, citing its strong performance metrics and usability features, but noted its small tank capacity and short hose as drawbacks.
When compared to other Shark models, the EX151 offers a more affordable option with near-flagship performance. The device's lightweight design and built-in hose system make it more accessible than heavier, more complex models. However, the EX151's performance in handling sticky and oily stains like peanut butter and tomato sauce is less impressive than higher-end models. The device's automatic soap and water dispensing and automatic extraction maximization features are also present in more expensive models, but the EX151's smaller tank capacity and shorter hose limit its overall utility. Overall, the EX151 is a solid value pick for users wanting effective cleaning, easy handling, and solid test-proven results, but it may not meet the needs of users requiring extensive cleaning capabilities.
Value at This Price
The Shark CarpetXpert EX151 is priced at $199.99, which is a significant discount from its original price of $249.99, making it an attractive option for budget-conscious consumers. Consumer Reports rated it 4.2/5, indicating that it offers good value for money, especially considering its strong suction performance and ease of maintenance. The device's ability to clean chocolate stains faster than average and its strong unsealed suction at the nozzle, measuring 3.35 nits, were noted as key strengths that justify its price point. However, the small water tank capacity and short hose length may require more frequent refills and limit its utility for large cleaning tasks, which could be a drawback for some users. Vacuum Wars also ranked the EX151 highly, noting its competitive performance metrics and usability features, but emphasized that its small tank capacity and short hose are limitations that may affect users who need to clean large areas.
The EX151's value proposition is further enhanced by its convenient features, such as the built-in hose system and automatic soap and water dispensing. These features simplify the cleaning process and make the device more user-friendly. The device's lightweight design and easy access to the brushroll also contribute to its value, as these features make it easier to maintain and use. However, the device's limitations in handling sticky and oily stains, as well as its small tank capacity, may impact its overall value for users who require extensive cleaning capabilities. Despite these drawbacks, the EX151 remains a strong contender in the mid-tier carpet cleaner market, offering a balance of performance and affordability that appeals to a broad range of consumers.
Long-Term Durability
While specific long-term durability data for the Shark CarpetXpert EX151 is limited, the device's build quality and design features suggest it is well-suited for regular use. Consumer Analysis noted that the device's components, including the brushroll and dirty water tank, are easily accessible and removable, which facilitates maintenance and potentially extends the device's lifespan. The inclusion of two filters in the dirty water tank is a positive feature that helps prevent clogs and ensures better filtration of debris, which can contribute to the device's longevity. The device's lightweight design and ergonomic features also suggest that it is built to withstand regular use without significant wear and tear.
Hint of Helen's six-month usage experience indicates that the device is reliable and effective for regular maintenance and spot cleaning. The ease of storage and simple operation contribute to its long-term usability, as users can easily incorporate it into their cleaning routine. The device's performance in cleaning carpets and rugs was excellent, and the convenience of its automatic features and built-in hose system make it a practical choice for ongoing use. However, the need for frequent refills and emptying of the water tanks may become a minor inconvenience over time, but it does not significantly impact the device's overall durability or functionality. The EX151's design and features suggest that it is built to last, provided users maintain it properly and avoid overuse in demanding conditions.
