I wanted our last family games night to be the best fun we’ve ever had. Maybe we should have stuck with Mario Kart …

It is the end of an era for the Diamond family. For 20 years, there have been five of us living together. It has not been easy. Militant vegan daughters, sons who have inherited Scottish tempers, and a youngest child who attracts trouble like an industrial magnet, have meant our house has been conflict-laden at times. Throw in the fact that we are beset with all manner of mental health bobbins and chronic illnesses that resulted in two of our three kids almost dying in hospitals and you get a family that is combustible – but extremely close.

Through it all, we had games. They always brought us back together. Not just us all hunkering over Super Mario Kart like some kind of UN-mandated family therapy, but the conversations that happen when any of us spy another playing something new. Games are a cultural touchstone that helped us crack through the veneer of disagreements and distrust and remind us that we have more things in common than we sometimes feel.

Shark’s cordless vacuum is a whiz at cleaning hard floors and pet hair, but a disarmingly short battery life caught our reviewer off guard

• The best cordless vacuum cleaners – tested

Vacuuming rarely starts with vacuuming. First you have to clear the floor of stray socks and abandoned toys left behind by children, pets or messy partners. Then there’s the irritation of finding the vacuum’s dustbin still full of dirt, or the battery flat because someone forgot to charge it.

The (take a deep breath – long name coming up) Shark PowerDetect Speed Clean and Empty Pet Pro cordless vacuum Ultramarine IA3241UKT certainly won’t pick up the scattered toys for you, but it has been designed to make the job of vacuuming as frictionless as possible.
