Dreame Z30 Cordless Stick Vacuum: features, specs and who it suits

The Dreame Z30 is a cordless stick vacuum that converts to a handheld, aimed at homes with a mix of carpets, hard floors and shedding pets. Dreame lists 850W of power and 310AW of suction, which adjusts itself to the amount of dirt it detects, and up to 90 minutes of runtime per charge. Lit floor brushes and a pet deshedding tool round it out.

850W and 310AW: what the numbers mean

The two figures measure different things. A wattage figure such as 850W generally describes the motor's power. Air watts (AW) describe suction at the cleaning end, combining how much air moves through the vacuum with how strongly it pulls. For comparing how well cordless vacuums lift dirt, air watts are the more telling number, though brush design and floor type matter too.

Dreame says the Z30 detects how much dirt is on the floor and adjusts the suction to match. Raising suction only where it's needed is a common way for cordless vacuums to make a charge go further.

Lights that reveal hidden dust

Lights on the floor brushes illuminate fine dust and debris that is hard to see on carpets, hard floors and tile. Dreame calls this Dust Reveal Technology. Light shining low across the floor makes small particles stand out, which helps most under furniture and in dim corners, where it's easy to miss a patch.

HEPA filtration

Dreame gives 99.99% whole-machine HEPA filtration efficiency for particles from 0.1 microns. HEPA-grade filters are designed to trap very fine particles. A "whole-machine" figure typically refers to the air leaving the vacuum as a whole, rather than to the filter on its own, since gaps around seals can let dust slip past even a good filter.

Tools for pet hair

A deshedding tool grooms a pet while the vacuum picks up the loose fur, so less of it ends up on the floor and furniture. Some pets need time to get used to grooming with a motor running nearby, so it's worth introducing it gently.

For sofas and upholstery, an anti-tangle motorised mini-brush handles pet hair without clogging. Long hair wrapping around a brush roll is a familiar nuisance with many vacuums, and anti-tangle designs aim to cut down on how often you have to cut it free.

Runtime, handheld mode and reach

The rechargeable battery gives up to 90 minutes of runtime, and Dreame's listing gives that figure with attachments. Maximum runtimes for cordless vacuums are generally measured on the lowest power setting; on higher settings, or when the suction steps up on thick carpet, a charge usually lasts noticeably less.

A flexible adapter bends to reach under furniture and into low corners. As a handheld, the Z30 covers stairs, sofas and car interiors, and Dreame describes it as a 4-in-1 design.

What's in the box and who it suits

The box includes two lit floor brushes, the pet tools, dusting brushes and a ground base.

It suits homes with shedding dogs or cats and a mix of floor types, for quick daily pickups as well as whole-home cleaning on one charge.

What to check before you buy

• Runtime on your settings: the manual's runtime for each power mode, not only the maximum.
• Dustbin: its capacity and how often you'd expect to empty it in a home with pets.
• Filters: how to wash or replace the filter, and how easy replacements are to get.
• Battery: the charging time and whether the battery can be swapped or replaced.
• Handheld weight: how it feels for stairs and upholstery, if you'll use it that way often.

The short version

• A cordless stick vacuum that converts to a handheld, with 850W of power and 310AW of suction (Dreame's figures).
• Suction adjusts to the dirt it detects; lit floor brushes reveal fine dust.
• 99.99% whole-machine HEPA filtration efficiency for particles from 0.1 microns, according to Dreame.
• A pet deshedding tool and an anti-tangle motorised mini-brush.
• Up to 90 minutes per charge; two lit floor brushes, dusting brushes and a ground base included.
