Furthermore, the Shark vacuum cleaner is easy to manoeuvre around furniture and glides easily over the floor. This is mainly due to the two rollers on the left and right of the floor head and the movable joint. A good cordless hoover should provide a deep clean on all surfaces. That's why we tested the Stratos on hard floors as well as low and high pile carpets. 🧐

Before you start vacuuming, the dust container, batteries and all other parts must be correctly inserted. A new feature for Shark cordless vacuums is the addition of anti-odour technology in the Stratos range.Although the Shark IZ420UKT superficially looks like its predecessor, the Shark IZ320UKT, this new model retains the best features of the old cleaner and adds some new ones into the mix. What’s more, Anti-Odour technology protects against bad odours inside the vacuum. Simply insert the dial into the floorhead and rotate it to select an intensity setting. Guard against dust cup odours with Shark. Additional Features The dust bin on the Shark Stratos IZ420UKT is fairly small, at 0.8litres, meaning that those looking to clean areas that are far away from their main bin might struggle. On the flip side, I think that making the capacity any bigger risks ruining the sleek feel of this vacuum, and I'm happy that SHark has kept it smaller.

There’s a large 0.7-litre bin on this model, which has an eject button to push open the flap at the front. As long as the Shark IZ420UKT was pushed into a bin, I could easily empty it without spilling dust everywhere.We assess the cleaning performance of each vacuum cleaner, compare it to the competition, and then rate it.
