You get what you pay for (does not apply to Dyson, which is overpriced). The construction of the vacuum cleaner and its individual components itself is not bad, but the suction power is not as high as in more expensive models (even after switching to a more powerful mode). So you have to compromise and either clean in a less efficient mode, for having a longer battery life, or set a higher suction power, but the cleaning is then half as long. Or you have to buy a second battery, which fortunately is not a problem. I give an additional minus for the hard to pull out telescopic tube from the dust container. Overall in the price/quality ratio I give a rating of 4/5, but it is worth waiting for promotions and price reductions.
