Our Verdict:
A critically acclaimed but 3 year old 0.34L dust capacity upright vacuum, with an extremely light 3.3kg weight and a good spec. It has a brush tool and a crevice tool and is cordless. Purchasers report that it has good suction, a powerful motor and it's really easy to use.

Why Has it Scored 79?

our review analysis indicates that it has great expert reviews and outstanding user reviews with 94% of buyers recommending this vacuum cleaner to others.
This vacuum cleaner is over 2 years old and it is likely that newer vacuum cleaners with better features are available. However it has good reviews so it may still be worth considering.
This Shark vacuum cleaner has some good features, but is also missing a couple of features:
Lighter than average
Cordless
Smaller than average capacity

What is the Kagoo Score?

We calculate the Kagoo Score for each vacuum cleaner by looking at its reviews, features, popularity, age, value for money and running costs.

The Kagoo Score is an easy way to understand whether the vacuum cleaner is recommended.

The Kagoo Scores are constantly being updated. As newer, higher spec vacuum cleaners come to market, the older vacuum cleaners will gradually have their Kagoo Score reduced.
