They’re perfect for time-poor cooks, but which deserves your counter space? From combi models to smart designs, here’s what our expert recommends

If you’re at a restaurant and hear a ping a couple of minutes before your meal arrives at your table, it’s unlikely to be a good sign. But microwave ovens are a brilliant tool in the home kitchen. They’re fearsomely fast at heating up – or even cooking – food when you’re time-poor and lacking the energy to make something wholesome after a hard day at work. And in hot weather, cooking by microwave isn’t just quick: it also won’t warm your home.

Microwaves work best for heating food with a high water content (they make the water molecules in food vibrate to create heat). However, before testing, I asked around to find out what people use theirs for most, with a view to using this information to shape my tests. I learned a few things – like lots of people eat mug cakes. Who knew? And that wheat bags are a popular alternative to hot-water bottles. But the majority of folk use their microwave for reheating cold cuppas, defrosting frozen batch-cooked meals, warming food, popping microwave popcorn – and, of course, cooking jacket potatoes more quickly. I used these insights to shape my testing.

Choosing a cordless vacuum isn’t a decision that should be taken lightly. You’re likely to keep a vacuum cleaner for years, relying heavily on its ability to suck up dust, crumbs, mud, pet hair and any other dry spillages or sheddings that end up on your floor. Choosing the right model can be the difference between an effective cleaner that’s a delight to pull out of the cupboard and a dud that you dread having to unblock, detangle and clean after every use.

In this review, I took 16 of the leading cordless vacuum cleaners from a range of manufacturers and at various prices and inflicted the same cleaning tests on each one. That takes all the guesswork out of picking your next cleaner: I can tell you exactly which ones picked up the most mess.
