✅ What we like about Shark IP3251 Cordless Vacuum

The powerful suction is a definite highlight, allowing the vacuum to efficiently clean even in hard-to-reach areas like under furniture and along edges. This suction power translates to effective cleaning overall, with the vacuum readily picking up dirt, dust, and pet hair from various floor types, including carpet and hardwood. The edge cleaning is particularly noteworthy.

The user-friendly design is another major plus. It is easy to set up, use, and maneuver. Cleaning and maintenance are simplified by the easy removal and reinstallation of the roller. The lightweight design makes maneuvering a breeze, especially for those accustomed to heavier vacuums.

✅ Comparison to similar models

✔ Shark IP3251 Cordless Vacuum vs. Shark IZ163H Cordless Stick Vacuum

The Shark IP3251 edges out the IZ163H due to its superior suction, claiming "Shark's most advanced cordless powered by our best cordless suction" compared to the IZ163H's "Powerful Suction," based on ASTM testing. The IP3251's auto-empty docking station provides significantly more convenience, eliminating the need for frequent emptying, which is a major advantage over the IZ163H which lacks this feature.

Furthermore, the IP3251 boasts a larger dustbin capacity (0.74 Quarts vs. 0.34 Quarts) reducing emptying frequency. Its longer runtime (up to 70 minutes vs. up to 40 minutes) enables cleaning of larger spaces. The DuoClean Detect brushroll, described as more advanced and reactive to floor types, surpasses the IZ163H's PowerFins technology. The inclusion of odor neutralization in the IP3251 adds a pleasant touch.

While both models offer beneficial features like being lightweight and having HEPA filters, the IP3251 features an odor neutralizing effect that the IZ163H lacks. The IZ163H stands out with its lighter weight (3.4 pounds vs. 18.48 pounds) and shorter charging time (40 minutes vs. 6 hours), making it easier to maneuver and quicker to recharge. Both vacuums have the MultiFLEX technology for under-furniture cleaning and compact storage, making it a tie.

The IP3251 also has a slightly higher customer rating (4.4/5) even though the IZ163H had many more ratings. The IP3251's convenience, driven by the auto-empty dock, higher suction, and overall convenience, outweighs the lighter weight and shorter charge time of the IZ163H. Though the IP3251 will be at a higher price point due to its more advanced features, it is the overall winner.

✔ Shark IP3251 Cordless Vacuum vs. Dreame R10 Pro Cordless Vacuum

Shark's IP3251 edges out the dreame R10 Pro. Shark benefits from being a more established brand in the vacuum cleaner market. While suction power isn't explicitly stated for the Shark, it is advertised as their "best cordless suction". Shark offers a slightly longer runtime of 70 minutes compared to dreame's 65 minutes. A major advantage for the Shark is its auto-empty base, which can hold dirt for up to 45 days. Shark's nozzle design, featuring DuoClean Detect with 2X Brushrolls & DirectionDetect, is more advanced. Shark also has a HEPA filter, providing better filtration. Finally, it has a slightly larger dustbin capacity of 0.74 quarts.

However, the dreame R10 Pro has some advantages. The charging time is significantly faster at 3.5 hours. The dreame also comes with more accessories for diverse cleaning needs. Its dimensions are more compact and the weight is significantly lighter (9.25 pounds vs. 18.48 pounds).

The wattage is significantly higher in the Shark vacuum with 380 watts, and the R10 Pro has 150 watts. The Shark vacuum also has a larger rating of 4.4 of 5 stars from the customers.

The R10 Pro has a noise level of 65dB but the Shark vacuum does not specify the noise level.

✔ Shark IP3251 Cordless Vacuum vs. Electrolux EHVS75S1AO Cordless Stick Vacuum

Alright, let's break down the Shark IP3251 versus the Electrolux EHVS75S1AO vacuum cleaners.

From a brand perspective, it's a tie. Both Shark and Electrolux are established names in the vacuum cleaner market. However, when it comes to pure cleaning power, the Shark edges out the Electrolux with its "BEST DEBRIS CLEANING" claim based on standardized testing. The Electrolux focuses more on fine dust.

A significant advantage for the Shark is its auto-emptying base. This feature alone gives it a big win, offering hands-free dirt disposal for up to 45 days. This also leads to a win in dirt storage as it seals dirt in the base for those 45 days, compared to the Electrolux's smaller 0.3-liter internal capacity. The Shark's DuoClean Detect nozzle technology, with its dual brushrolls and improved pickup, surpasses the Electrolux's PowerPro Bristle Nozzle.

The Shark also incorporates intelligent technology, like PowerDetect and DirectionDetect, which automatically adjusts power based on the surface being cleaned. This type of automation is not listed for the Electrolux. Furthermore, the Shark's MultiFLEX wand provides better reach under furniture. The Shark's odor neutralization feature is a bonus, enhancing the overall cleaning experience. And regarding runtime, the Shark gives you up to 70 minutes of cleaning compared to the Electrolux's 50 minutes. The accessories package also looks more comprehensive with the Shark, especially with the inclusion of a Pet Multi-Tool.

However, the Electrolux scores some important points. It's significantly lighter than the Shark, making it easier to maneuver, especially for those with mobility issues. Electrolux uses at least 43% recycled plastic in its construction, making it a more environmentally conscious choice. While both vacuums have great filtration, the Electrolux's 5-step filtration system specifies its ability to trap 99% of particles down to 0.3 microns. The Electrolux also boasts a faster charging time of 4.5 hours compared to the Shark's 6 hours, and the measured noise level is 80dB.

But the Shark has a 0.7-liter capacity, almost double the Electrolux. And the Shark also has a higher wattage of 380 watts versus 250 for the Electrolux, hinting at more suction power. The Electrolux is more compact in its dimensions, giving it an edge in storage. The Shark has better customer ratings, with a 4.4 out of 5 stars compared to the Electrolux's 3.9.

Price remains a deciding factor until the prices are determined for both vacuums.

✔ Shark IP3251 Cordless Vacuum vs. SMOTURE VAC01 Cordless Stick Vacuum Cleaner

Shark and SMOTURE face off in this vacuum cleaner comparison. Shark, a more established brand, is pitted against the SMOTURE VAC01.

Suction power is a key battleground, and here, SMOTURE takes the lead with a specified 45KPA, whereas Shark only claims "best cordless suction," lacking concrete data. However, Shark strikes back with a longer runtime of up to 70 minutes compared to SMOTURE's 60.

SMOTURE continues its winning streak with a faster 4-hour charging time and a significantly larger dustbin capacity (1.58 quarts) compared to Shark's 0.74 quarts, resulting in less frequent emptying. The SMOTURE is also much lighter at 6 pounds, compared to Shark's hefty 18.48 pounds.

Despite Shark's weight disadvantage, it has superior special features, including an auto-empty base, odor neutralizer, DuoClean Detect Nozzle, MultiFLEX Wand, PowerDetect Technology, and DirectionDetect Technology.

Both vacuums utilize high-quality filtration systems, resulting in a tie in this category. However, SMOTURE bounces back with a more generous accessory package, including an extra HEPA filter, aromatherapy tablets, and an anti-tangle roller.

SMOTURE boasts a higher wattage (550 watts) indicating a potentially more powerful motor, and operates at a quieter 64 dB. Customer ratings also favor SMOTURE, with a 4.7 out of 5 stars from a large pool of 2,315 ratings, compared to Shark's 4.4 stars from 327 ratings.

The critical factor of price is unavailable, making a complete assessment impossible. Shark has Auto-Empty feature and SMOTURE does not.

SMOTURE's dimensions are also more compact than Shark's.

✔ Shark IP3251 Cordless Vacuum vs. ZCAISH Z01-US2 Cordless Stick Vacuum

Shark's IP3251 excels in brand reputation, backed by a well-established name and track record. Its debris cleaning capabilities are also superior, based on specific tests showcasing its effectiveness. A major advantage is the automatic self-emptying base, providing up to 45 days of hands-free convenience. Furthermore, the Shark model offers a longer runtime, reaching up to 70 minutes in Eco Mode. The advanced brushroll design, featuring DuoClean Detect with forward and reverse cleaning, is another key differentiator. Special features like PowerDetect, DirectionDetect, MultiFLEX wand, and an odor neutralizer enhance the overall user experience.

However, the ZCAISH Z01-US2 counters with a larger dust cup capacity of 1.5 Liters, requiring less frequent emptying. It also boasts a faster charging time of 4 hours. The ZCAISH vacuum specifies a suction power of 45Kpa. Its filtration system is a 5-layer HEPA filtration with fragrance, possibly improving air quality.

The ZCAISH also stands out for its significantly lighter weight of 9 pounds, improving maneuverability. The inclusion of a short brush head, long crevice nozzle, hair cleaning tool, and replaceable HEPA filters adds value. It's also usually more budget-friendly.

✔ Shark IP3251 Cordless Vacuum vs. AFNOP Pure 16 Cordless Vacuum Cleaner

When comparing the Shark IP3251 and the AFNOP PURE 16 cordless vacuums, several key differences emerge. The Shark claims superior cordless suction based on testing, making it the likely winner in this category, even though AFNOP quantifies their suction at 45000pa. The Shark's auto-empty base, which empties and charges the vacuum and locks away dirt for up to 45 days, is a significant convenience feature absent in the AFNOP model. Further bolstering Shark's position is a longer runtime of up to 70 minutes in ECO mode, compared to AFNOP's 60 minutes on its minimum suction setting.

However, the AFNOP PURE 16 gains ground in other areas. Its charging time is faster at 4 hours, compared to the Shark's 6 hours. The AFNOP also boasts a larger dust cup capacity of approximately 1.58 quarts, exceeding the Shark's 0.74 quarts. A major advantage for AFNOP is its significantly lighter weight of 8 lbs, compared to the Shark's hefty 18.48 lbs.

The special features of each vacuum present a mixed bag. The Shark offers a DuoClean Detect nozzle, DirectionDetect Technology, MultiFLEX wand, and an odor neutralizer. The AFNOP counters with a self-standing design, a dual-screen display, and a V-shaped tangle-free brush. Both vacuums utilize HEPA filters, resulting in a tie in filtration. AFNOP has a multi-cone filtration system too.

AFNOP's 550 watts of wattage is higher than Shark's 380 watts, which may lead to better performance. The accessories offered by both vacuums are comparable and cater to different needs, resulting in a tie. The dual-screen display on the AFNOP provides more immediate information about the vacuum's status. Finally, Shark benefits from its well-established brand reputation in the vacuum cleaner market.

✔ Shark IP3251 Cordless Vacuum vs. Eureka NEC490BL Cordless Stick Vacuum

The Shark IP3251 edges out the Eureka NEC490BL, primarily due to its stronger brand reputation within the vacuum cleaner market. While suction power is difficult to definitively quantify without direct testing, Shark's marketing heavily emphasizes its advanced cordless suction capabilities. Both vacuums feature a convenient auto-empty function, a major selling point for this category. However, Shark includes a debris locking feature, a benefit that the Eureka does not explicitly mention.

Shark's nozzle technology also appears to be more advanced, boasting dirt detection, power boosting, and forward/reverse pickup, compared to Eureka's anti-tangle nozzle. The Shark further surpasses the Eureka in runtime, offering up to 70 minutes on ECO mode, and accessory selection. The Shark includes a more specialized duster crevice tool, odor neutralizer puck, and pet multi-tool.

Conversely, the Eureka wins in dustbin capacity (2.5 liters versus Shark's 0.74 quarts), charging time (4 hours versus Shark's 6 hours), and weight (17.64 pounds versus Shark's 18.48 pounds). While both offer HEPA filtration, the Eureka quantifies its efficiency at 99.9% particle separation. Customer reviews also favor the Shark slightly, with a rating of 4.4 out of 5 stars compared to Eureka's 4.2. Price information is unavailable for both models, making a complete comparison impossible. Lastly, Shark incorporates unique features such as MultiFLEX technology for under-furniture cleaning and compact storage, and Odor Neutralizer Technology which is superior to the Eureka.

✔ Shark IP3251 Cordless Vacuum vs. AZVKEA S17 Cordless Stick Vacuum Cleaner

Shark IP3251 edges out AZVKEA S17 in brand recognition due to its established reputation. However, price remains unknown, preventing a complete cost-benefit analysis.

When it comes to cleaning, Shark's claim of "best debris cleaning" carries weight, indicating superior performance. A key advantage for Shark is its self-emptying base, a significant convenience feature absent in the AZVKEA. Shark also offers a slightly longer runtime, up to 70 minutes compared to AZVKEA's 60 minutes. On the flip side, the AZVKEA recharges faster, requiring only 4 hours compared to Shark's 6. Both vacuums use HEPA filters for allergen removal, resulting in a tie in filtration.

The AZVKEA boasts a larger dust capacity, 1.6 liters versus Shark's 0.74 quarts, meaning less frequent emptying (although Shark has the self-emptying base). Its higher wattage of 550 Watts compared to Shark's 380 Watts also suggests potentially stronger suction. The AZVKEA is significantly lighter at 6.99 lbs compared to Shark's 18.48 lbs, enhancing maneuverability. The AZVKEA also includes a more comprehensive set of accessories.

Looking at special features, Shark incorporates advanced technologies like PowerDetect, DirectionDetect, and MultiFLEX, along with an odor neutralizer. However, the AZVKEA's dual handle design likely enhances maneuverability. Customer reviews favor the AZVKEA with a 4.6-star rating (735 ratings) compared to Shark's 4.4 stars (327 ratings). The AZVKEA also has a known noise level of 64 dB and has emphasis on customer service.

✔ Shark IP3251 Cordless Vacuum vs. dsorupa V10 Ultra Cordless Vacuum Cleaner

When comparing the Shark IP3251 and the dsorupa V10 Ultra cordless vacuums, Shark has the advantage of being a more established brand in the vacuum cleaner market. However, dsorupa boasts a specified suction power of 45KPa, giving it an edge in quantifiable performance, even though Shark claims the "best cordless suction."

Shark offers the convenience of an auto-empty base that seals away dirt for up to 45 days, a feature not found in the dsorupa. The Shark's DuoClean Detect brushroll technology appears more advanced with its dirt, edge, and carpet detection capabilities, whereas dsorupa uses a combination of soft and hard brushes with an anti-tangle design. Both vacuums offer a runtime of up to 70 minutes.

dsorupa shines with a faster charging time of 3.5 hours compared to Shark's 6 hours. It also has a significantly larger dustbin capacity of 1.8 Liters versus Shark's 0.74 Quarts, reducing the need for frequent emptying.

The dsorupa features an 8-stage filtration system with an aroma tablet, potentially offering better filtration and odor control than Shark's HEPA filter. Additionally, dsorupa incorporates an integrated LED display for real-time information, a feature absent in the Shark model. A notable advantage for dsorupa is its lighter weight of 8 pounds compared to Shark's 18.48 pounds.

While Shark includes an odor neutralizer puck, dsorupa lacks this feature. Both vacuums include wall mounts with auto-charging capability. Shark offers compelling special features like PowerDetect, DirectionDetect, MultiFLEX technology, and Odor Neutralizer Technology, largely due to auto-empty base.

Customer ratings favor dsorupa with a 4.9 out of 5 stars from 455 ratings, surpassing Shark's 4.4 out of 5 stars from 327 ratings. Assuming dsorupa has a lower price point, it represents a better overall value.

✔ Shark IP3251 Cordless Vacuum vs. KCLASO V10 Cordless Vacuum Cleaner

When comparing the Shark IP3251 and the KCLASO V10 cordless vacuums, several key differences emerge. Shark benefits from being a more established brand, which often translates to higher reliability and better customer support. However, when it comes to pure suction power, the KCLASO V10 takes the lead with a verifiable 45Kpa, surpassing the Shark's claim of "best cordless suction."

A major advantage of the Shark is its auto-empty feature, a significant convenience that greatly reduces the frequency of manual dust cup emptying. While both vacuums use HEPA filters, the KCLASO's 5-layer filtration system provides a more comprehensive cleaning process. The Shark offers a slightly larger dust cup capacity at approximately 700ml compared to the KCLASO's 500ml.

In terms of runtime, the Shark boasts up to 70 minutes on Eco mode, while the KCLASO offers up to 45 minutes. The KCLASO charges slightly faster, taking 5 hours compared to the Shark's 6 hours.

The KCLASO is significantly lighter at 6.64 lbs compared to the Shark's 18.48 lbs, making it easier to maneuver. The KCLASO also operates at a lower noise level, specified as below 75dB.

Accessory sets are comparable between the two. The KCLASO comes with a touchscreen, providing convenient access to mode selection, battery level monitoring, and error message displays. Furthermore, the KCLASO V10 is more compact in its dimensions. Assuming the KCLASO is offered at a lower price point, it represents a good value for its features.

✔ Shark IP3251 Cordless Vacuum vs. FoxNoble Cordless Vacuum Cleaner

Shark wins in brand recognition, boasting a well-established name and generally positive reputation within the vacuum cleaner market compared to the lesser-known FoxNoble. When it comes to cleaning performance, Shark's claims are more detailed and supported, implying superior cleaning capabilities. Furthermore, the automation offered by Shark's auto-emptying base provides considerable convenience. Finally, Shark maintains the advantage in runtime and technologies.

On the other hand, FoxNoble takes the lead with a larger dustbin capacity and a more comprehensive accessory kit. In addition, FoxNoble has a better charging time, filtration, user interface and warranty. The FoxNoble is also lighter.

Price information is missing, so no conclusion can be reached on this point.

✅ Conclusion
