This smell may indicate a leaky pipe or other water source that needs to be fixed.

This halves the effective run-time, although the IZ201UKT is a cheaper option.. Shark IZ251UKT Verdict.We’re impressed by the features and performance of the Shark IZ251UKT cordless vacuum.

The stick design with a handheld mode is familiar, but features like anti hair wrap, Flexology stick, DuoClean floorhead, and dual battery design set the vacuum apart from its competitors..The IZ251UKT is also brilliant for cleaning hard floors, pet hair, and staircases.It provides strong suction when in its regular mode, while the boost option is useful when you need some extra power.. It’s not perfect though.

The IZ251UKT falls over unless you fold the stick, which can be frustrating when you quickly need to move something when cleaning.We also don’t think it’s as effective on carpets as some of its competitors..

Even so, the Shark IZ251UKT is an excellent cordless vacuum and a worthy competitor to both.

and Tineco models.. VIEW PRICEThe primary floorhead is built with Shark’s DuoClean technology with two motorised brush rolls.

This has a regular brush bar for carpets, along with a softer roller for picking up both large debris and fine dust from.The soft brush is also in continuous contact with the floor, which helps to reduce scattering.. A bonus is that the IZ251UKT’s floorhead has Shark’s anti hair-wrap technology.

This consists of several combs that prevent hair from becoming caught round the brush bar, so you don’t need to cut hair away from the roller.We don’t think it’s 100% effective, but it does a good job at forcing hair into the bin, especially if your vacuum has to deal with long hair.. As with most.
