I bought this vacuum to replace an old dying man sled .son design is remarkable, quality materials and as .the pub says it does not lose suction. It allows to do some cleaning every day because it is always at hand. But autonomy is still somewhat limited, about 15 minutes or 8 to maximum power. However, as it is wireless, you can clean the car or clean the corners of the house easily. If you have an apartment of more than 70m2 with carpet in all the rooms, it is not for you. If not for daily cleaning it is perfect!
