Who should buy Shark IZ251UK

  • If you live in a large house, you might be satisfied with the Shark IZ251UK because it has two batteries. Hence, you can replace the drained battery with a fully charged one, giving you enough time to clean your entire home.
  • If you have long hair or have pets that shed heavily, the Shark IZ251UK might be suitable for you because its brush is not prone to hair tangles since it has an anti-hair wrap brush.
  • If you have many low-lying furniture, the Shark IZ251UK can be great because you can fold the flexible tube so that it can easily clean under the furniture, such as the table or bed and you don't have to bend over or kneel.
  • If you have a mix of hard floors and carpets, the Shark IZ251UK might be perfect for you because its main nozzle, called the DuoClean floor nozzle, has two brushes intended for hard floors and carpets.

Who should NOT buy Shark IZ251UK

  • If you are looking for a cordless vacuum that is not heavy, the Shark IZ251UK might not be suitable for you because it weighs about 4,1 kg which might slightly strain your upper arm if you use it for an extended time. Instead, you might find other cordless vacuums more suitable, such as the Dyson V8 Absolute that weighs 2,6 kg or the Philips XC7042/01 that weighs 2,73 kg.
  • If you are looking for a cordless vacuum that comes with various cleaning attachments to choose from, you might want to look for other cordless vacuums such as the Dyson Cyclone V10 Absolute that has six cleaning nozzles.

Verdict

This is our verdict of the Shark IZ251UK based on several hours of research of reviews from both experts and users.
Updated 10-08-2021

The Shark IZ251UK boasts its anti-hair wrap brush which is most suitable for those who have long hair or heavy shedding pets. It is a bit expensive since it provides thorough cleaning and has a DuoClean floor nozzle that can be used for hard floors and carpets.

Its main nozzle, which is the DuoClean floor nozzle, has two brushes inside. This is helpful especially for those who have a mix of hard floors and carpets so that they won't have to replace the brush depending on the floor type. The floor nozzle is also wide so large crumbs and dirt can be cleaned easily. It also has LED lights at the tip of the nozzle, which resemble a car's headlights to illuminate dark corners and give you more visibility.

Another feature that the Shark IZ251UK boasts is its flexible tube which the company calls as the Flexology tube. You can use it to clean under the furniture, such as tables or beds without bending over which makes the vacuum very back-friendly. You can also use the Flexology tube to make the Shark IZ251UK stand. If you don't bend the Flexology tube, the Shark IZ251UK will fall because the handle on the top is heavy. Meanwhile, if you bend it, the handle's weight will be closer to the ground, which will help it stand.

You cannot adjust the suction power of the Shark IZ251UK like in other cordless vacuums, such as the Dreame V11 that has three suction modes to choose from (Eco, Maximum, and Turbo). In the Shark IZ251UK, you can only boost the suction mode using the boost trigger. The boost trigger is excellent if you needed an extra suction to pick up tough specks of dirt. There is no lower suction mode so you have to bear the loud noise.

Another great feature of the Shark IZ251UK is its replaceable battery. There are two batteries in the box and a charger where you can charge both batteries. This is great for those who have large houses, so that in case the battery died and you haven't finished cleaning yet, you can just replace the drained battery with a fully charged one. Moreover, you can charge the battery directly using the charger cable or use the charging station which can charge two batteries at the same time. You can even charge the battery while it is still attached to the vacuum.

However, the Shark IZ251UK is a bit heavy, about 4 kg, so it might strain your arms if you use it for a long time and if you are not used to lifting heavy things. It is also loud unlike other cordless vacuums with bearable noise levels, such as the Philips XC8045/01 with an 84 dB noise level or the AEG CX7-2-45BM with a 79 dB noise level.

Overall, the Shark IZ251UK is worth its price, especially for those who have large houses and those who have a mix of hard floors and carpets.
