I have run vacuum cleaners sorry seems we are using correct words, so it does not produce a vacuum so should be called an air velocity cleaner, from a generator sorry electric generator many times.
The maximum wattage will be lowered even further to 900 watts in 2017. The current average on the market is about 1,800 watts. Currently vacuum cleaners are the only products subject to the ban – although next year the EU plans to scrutinise other household appliances.
So with a new generator of 1000 watt a new vacuum cleaner should work, it states maximum wattage not running wattage.
However when working on building sites the wet vacuum cleaners had three 900W motors and would trip out the 110 volt 16 amp supplies and needed a 32 amp supply, it seems it was common to have two 16A sockets on one 20A MCB and with that they would work, but our 16A sockets had 16A MCB's and it was causing us a problem other wise I would not realise how big they were.
There are three common ways to control a generator, an inverter often larger than the generator allowing you to use two generators together, an automatic voltage regulator, and last using two field coils one in series and one in parallel this method means voltage only spot on at two loads, and depending on the design is if the generator will allow over current or not, some will not generate if you leave a load on them at start up, the field will fail on overload and whole thing shuts down, others can actually burn themselves out the only protection is an output MCB.
So no one can answer question as we don't have required information.
I remember in the Falklands we had two generators delivered and boss said we don't need any more generators at the moment leave them in the boxes. Then we did need extra so we unboxed them only to find they were acetylene generators, seems the welding department had been hunting for them. So yes suppose we should use correct names, bicycle dynamos have not actually been dynamos (DC generator) for years, they were nearly all alternators.
Since really an air velocity cleaner then does the ban on wattage cover them?
