Dyson believes that cordless vacuums will be the future, whether handheld or robotic, but battery technology has been the big sticking point. The most recent V8 cordless claims to last doubly long and have the ability to completely replace a corded vacuum.

The Dyson V8 may be the latest in an extended line of handheld floor cleaners, which started life as the DC16 in 2007. Since that time, they’ve are more powerful, and with improved energy-efficiency and batteries, they go longer between charges. They’ve also gained floor tools and wands to carefully turn them into full vacuum-cleaner replacements.

The big difference between your V8 and last year’s V6 is that the brand new Dyson cordless claims to last for 40 minutes battery life. Could it be finally enough to completely clean the whole house?

Pros of cordless
No restrictive cord or cylinder
More manoeuvrable
Don’t need to stop to unplug
More compact
Faster to deploy
Cons of cordless
Smaller bin
Weight in the hand
Less powerful
Must be charged
Batteries wear out

The V8 (find here) is probably the most manoeuvrable and easy-to-use floor cleaners available. Fit an instrument, press the trigger and off you go. Dyson’s system for attaching and detaching peripherals is quick, easy and feels robust – just push a button and slide apart, snapping another piece into place. This means going from a hand vacuum with crevice tool to a complete vacuum takes seconds.

Unlike a corded vacuum, there’s nowhere to store the unused ends on the cleaner, which would add weight, nonetheless it is somewhat of a pain.

With a wand and cleaning head attached, the V8 handles such as a cylinder vacuum’s wand without the weight of the connecting tube and main unit to drag around on to the floor. It feels completely different to an upright, but using it quickly becomes natural. The largest difference is that because almost all of the weight is in your hand it’s a whole lot simpler to grab and move the top around without dragging it over the floor.

Despite weighing only 2.6kg and being lighter than almost every other cordless vacuums, I came across that after cleaning a complete home with the V8 I possibly could feel the muscles in my own hand and arm commence to ache. Relaxing my grip and letting the top on to the floor take the weight helped, nonetheless it is something you must get used to.

Found in short bursts, the V8 is far more balanced than most handheld vacuums and cleaning the stairs was so easier with the Dyson than an upright or cylinder vacuum.

A switch on the most notable varies between maximum and normal suction. Leaving it on normal with the powered fluffy or carpet head was plenty of for regular vacuuming, providing an identical degree of cleaning to a Dyson upright. It had been also a whole lot quieter, particularly with the fluffy head attached; I possibly could hold a complete conversation without shouting while cleaning a difficult floor.

Flicking the switch to max sends the cleaner right into a frenzy, drastically increasing the suction power, the volume of air it fires out the trunk, noise and battery consumption. It had been useful for the odd spot that couldn’t quite be reached with the crevice tool or that was heavily soiled, but wasn’t needed frequently.

Dyson claims the V8 can last for 40 minutes with out a powered head, using the crevice tool or similar suction-only accessory. It’ll last up to thirty minutes with the fluffy head attached, up to 25 minutes with the original spinning brush head or seven minutes when in maximum suction mode.

I came across the battery life a lot more than long enough. An intensive clean of four rooms, a kitchen, a bathroom and a flight of stairs with both carpeted and hard floor surfaces, including cleaning around the edges with the crevice tool, and using the mini motorised at once the stairs, left me with one-third of the battery left.

A lighter weekly clean left about 50 % in the tank, while I possibly could make make use of it for a complete day of clearing up after and during DIY without issue. A complete charge takes five hours and the V8 could be placed in a wall-mounted dock that holds and charges the key unit, plus has clips for just two accessories. The other accessories, like the other motorised heads must be placed separately, which is somewhat messy.
