The Bosch Athlete one I have barely does the time I want it to. The red full light comes on too much. I try and wash the filters every week or so but it is so annoying.
I don't think you will escape filter washing. I have got a Dyson V10 and two large dogs who tread in mud and junk from the garden. I can do the entire downstairs and stairs, landing and three bedrooms on one charge and I need to empty the bin at the end. Filter gets washed around once a month. Its in the nature of cordless machines to have smaller bins and need emptying more often.
I have a GTech. It's lightweight, very efficient and easy to use. About an hour on a full charge. I also have the hand held, ideal for furniture, the car and everything else.
I have got a problem with Gtech in that they no longer make the chargers for my garden tools. They are about 6 years old and in excellent condition but I can’t get replacement chargers for them so be warned
