We're sad to say it but the following deals have all now closed. Have a look at our round-ups of the best Christmas tech deals for the latest and greatest offers. 

The Eufy RoboVac 30C is on sale on the Eufy site until 1st December for £169.99, down from £269.99 – that’s £100 off or a 37% price drop. You’ll also get free shipping. Earlier this month, we reviewed it. We called it “one of the smartest robot vacuum cleaners around” and gave it 4.5 out of 5 stars.

The RoboVac 30C is a connected device. You can control it via an app but it’s also Alexa and Google Assistant compatible, so if you prefer, you can use voice commands to set your little robo-cleaner to do your bidding.  

It has some good features. When its charge depletes, it will return to its base for more juice. Its large wheels allow it to roll over carpet edges and door ledges to continue its cleaning mission. And the device can be left to its – shall we say – own devices, as it has drop-sensing technology to help it avoid daring plunges down the stairs.

At 55dB, it’s one of the quieter models available (for reference, that’s about as noisy as your fridge). It's also among the slimmest, at only 2.85 inches high, giving it a decent shot at getting under your furniture - so you don’t have to.    

Bear in mind that once you invest, you need to take care of your vac by cleaning its sensors and replacing the filters, brushes and brush guards regularly. Remember – a robot cleaner may not be for life but you want it to work beyond Christmas.

There are also deals on the RoboVac 11S, which is down from £199.99 to £146.99 (a saving of £53) and the 11s MAX, which is down from £239.99 to £174.99 (that’s £65 off).

Also, if you head over to Amazon and click the voucher box to apply the discount, you can get £50 off the Eufy RoboVac 15C MAX
