Only 168 online shopping days to Christmas...

A robotic hoover that does your housework for you and a gadget that makes the “perfect” cup of tea are set to be among the most popular gifts this Christmas, experts said today.

Amazon, which previewed hundreds of products available over the 168 shopping days until Christmas, said they are set to be among the biggest sellers.

The iRobot Roomba, on sale for £499.77, can be operated by remote control, “senses” feet and stairs and can even be preset to do housework while you are on holiday.

The gadget, which looks like a flying saucer, was developed using minesweeping technology.

Also set to be popular is The Tea Maker, made by Sage, developed by chef Heston Blumenthal.

The product, which costs £199.99, is designed to make the ultimate cup of tea as users can control the strength and temperature.

It can be preset to make tea for a particular time. Other popular gifts are expected to include interactive toys such as the Teksta robot puppy and Sugar The Seal, both £59.99, and Sony’s £219 Action Camcorder which is HD, waterproof, has wifi and can be used to film underwater.

Amazon spokeswoman Clare Kelly said: “Obviously it’s difficult to have a hoover as a gift but this one makes it fun. The Tea Maker is perfect for tea lovers, people get really geeky about our their teas.”
