Another vacuum, or range of vacuums, to throw into this mix is the Nilfisk Alto Attix range. I've spent time comparing the Festool CT22, the Fein Dustex 2, and the Alto Attix 360-21 over the last few weeks. My opinions on the machines are based entirely on their printed specs, on what reviews I could find, and on feedback from users of them both on this forum and elsewhere.
I have been planning to start a thread to put the info that I dug out about them in one place, for easy reference by anyone else making a decision amongst these machines - some of the info is not very easy to find. I have been holding off on this though until I have used my machine of choice (the Alto Attic 360-21) so that I could put some feedback in there too. It still hasn't arrived, but in case it is of any help, the following are what put it to the top of my list of choices:
- It is a reasonable price (relatively speaking!) of £249 in most cases, but currently on offer from D&M Tools (
http://www.dm-tools.co.uk/product.php/section//sn/ALTATTIX36021) for £199 for April.
- its spec is almost identical to the Festool, including power take-off, auto-start, and it runs for a few seconds after tool is stopped (only found this bit of info from the online manual). The main differences are that Festool claims airflow of 3800 l/min versus 3600 l/min for the Alto, Festool claims max power take-off of 2400W versus 1800W for the Alto (Alto claims 2400W elsewhere in Europe, which makes me wonder about whether the Festool is really 2400W in the UK and Ireland).
- it claims to be the quietest at 57dB versus 72dB for the Festool. I plan to use this as the house vacuum cleaner too so the noise level is important to me for a couple of reasons.
- the Alto is a more convenient size and shape for me - it's a bit like the Festool stood on one end so takes up less floor space.
- the Alto will handle MDF dust, and its ilk, just by using one of its filter bags but I don't know about the Festool. Neither of them are marketed as handling this dust but in the case of the Alto this is because extra features such as an alarm for when it is full, are needed to meet European regulations - the same may apply for the Festool but I don't know for sure whereas Nilfisk Alto have confirmed it when asked.
Obviously my choice is biased towards my specific needs, but it seems to me that the Nilfisk Alto is well worth considering as a more economical alternative to the Festool with what appears to be the same spec. Incidentally, I ruled out the Fein for my needs for a number of reasons (no anti-static hose, smallest airflow, etc.) but it's spec looks good in its own right and it is the cheapest.
