Unfortunately this vacuum can not replace a canister vacuum: it works perfectly on parquet, tiles, sea grass, short carpet, but it is unusable on a shag. In the same vein: do not think of using it to suck inside your car. His head with motorized brush is powerful, but it does not go anywhere: you can not suck the crumbs on the couch, dust in radiators .. more generally: you will not go into the corners.
So you will have another vacuum cleaner either a sled or a hand vacuum ... probably not both, unless you want to get started in farming vacuums.
For a budget equivalent to the PowerPro Uno, you can offer two new vacuum cleaners: Philips PowerPro Duo and vacuum cleaner midrange sled type PowerPro Active. The PowerPro Duo is the twin of the 'Uno' with two differences: it has a 12v battery for a battery life of 20 minutes, but mostly it is a combined upright vacuum cleaner + detachable hand vacuum: it will provide the bulk Lentretien of the house to the back of the sofa and radiators. As for the midrange sled, it will serve you extra for carpets longhaired and car.
Conclusion: Overpriced for an extra not at all versatile.
