Further update
Well, after a month on trial, using once every 2 days, I can now point out the pros and cons of the Vax Zoom.
Pros:
The Zoom is a very good budget vac in my opinion, which cleans very well indeed and has a good hose and handle extension.
It has very powerful suction which did not appear to diminish much at all during the gradual filling of the dust container, which I allowed to fill to the MAX line over the space of a month's use.
It is easy to push as long as the height adjustment is set correctly.
It is reasonably well made and I would imagine it would last a few years if used correctly.
The range come in good colour schemes.
The filter is easy to wash out and the primary separator assembly simply pulls out of the bin for easy washing.
The vac is not heavy and is easy to carry.
It has motor soft start and is not overly noisy in use.
It has a longer than average cable for its price point, and this has adequate stowage space on the back of the vac.
Cons:
The lint picker strips on the turbo tool came to bits over the first month of use and had to be pulled off (quality control issue).
The vac does not sit high enough off the ground when using the hose and tools to keep the brushroll from contacting carpet as the vac moves due to the hose being pulled (Design flaw)
The handle does need some kind of rubberised hand grip on it to make it more comfortable to use. (Design flaw)
The vac does not have a storage place built on for the multi tool. (but it does include one for the turbo tool). (Design flaw)
The exhaust filter does emit some very fine black dust which is evident on the bottom of the dust container after a month's use. (Exhaust filter foam insufficient?)
The belt is not easily accessible requiring tools and removal of many screws to replace it. (Bad design)
Filters are very expensive at £19.99 for the filter pack from Vax, although they are washable, they will need replacing eventually. (Corporate greed)
Final Score:
So, overall, it does have a few design flaws and the odd poor quality issue on the turbo tool which have come to light since buying it, but on the whole, I still like this vac and would be happy to give it an overall score of 8/10 based on the sub £100 price point.
Yes, I would buy one again, and I would recommend them to anyone except the elderly as I think with the colour schemes used these are intended for the younger generation. Also, I think the elderly would struggle to replace a drivebelt due to the complexity of dismantling the base to get to it.
I do think though that Vax seriously need to re-consider the price of the pre-motor filters as they are just not worth £20.
