BISSELL CrossWave OmniForce Cordless All-in-One Wet & Dry Multi-Surface Floor Cleaner (3912E)
Data last updated:
Our verdict
At around £144.94, the CrossWave OmniForce is the cheaper end of BISSELL's cordless wet/dry lineup, and its 30-minute runtime and 0.66L tank are enough for a small-to-medium hard-floor home rather than a large or heavily carpeted one. HEPA filtration isn't confirmed, so allergy-focused buyers should verify that detail before purchasing rather than assuming it. For anyone with a compact hard-floor space and a tight budget, it's a reasonable entry point into wet/dry cleaning.

What is the BISSELL CrossWave OmniForce (3912E)?
The BISSELL CrossWave OmniForce is a cordless wet-and-dry floor cleaner built for hard floors and tile rather than carpets. It vacuums and mops at the same time in PowerMop Mode, or can be switched to a dry-vacuum-only PowerVac Mode. BISSELL states PowerVac delivers 75% more suction than the previous CrossWave X7 generation. It sits within BISSELL's wider cordless CrossWave line-up, alongside models such as the C6 Cordless Pro and HF3 Cordless Pro.
Price
Across UK retailers tracked by idealo.co.uk, the current lowest price is £144.94. A separate new/sealed listing on eBay UK quotes an official RRP of £399.99 for the same model, so the gap between RRP and current street price is significant. Prices and stock vary by retailer, so it's worth checking current listings before buying.

Cleaning modes and features
- Two-Tank Technology keeps clean and dirty water separate.
- PowerVac Mode for dry vacuuming only.
- PowerMop Mode for simultaneous vacuuming and mopping.
- Turbo Mode for deeper cleaning, which reduces runtime to about 18 minutes.
- Tangle-free brush roll.
- Automatic self-cleaning cycle run via the charging/storage dock — this cleans the brush roll and internals, not a self-emptying bin; the machine is not self-emptying.
- Quick-release dirty water tank and a swivel steering head for manoeuvring around furniture.
Included in the box: a charging/storage dock, a trial-size bottle of BISSELL Multi-Surface cleaning solution, and a hair strainer.
Battery life and charging
Runtime is up to 30 minutes on the standard PowerVac or PowerMop settings, dropping to 18 minutes if you use Turbo Mode. A full charge takes roughly 4 hours. The battery is a 36V Li-ion pack; BISSELL doesn't publish an exact Ah rating for it, though the figure works out to approximately 1.8Ah based on the energy rating listed for this model.
What's not confirmed or missing
- HEPA filtration: not confirmed either way. One retailer listing for this model describes a HEPA filter, another describes a cloth filter, and BISSELL's own spec sheet doesn't clarify — treat this as unverified.
- It is not self-emptying and not app-controlled.
- It's designed for hard floors and tile only, not carpets.
- Weight and dimensions each come from a single retailer source rather than the official spec sheet, so treat them as approximate.
Is the CrossWave OmniForce right for you?
With a 0.66L tank and 30-minute runtime, this model suits a small-to-medium home with hard floors or tile that needs topping up between charges rather than a large property needing long, uninterrupted runs. If you have carpets to clean, or need confirmed HEPA filtration, this specific model won't cover that. For alternatives, browse other Bissell vacuum cleaners or compare other wet and dry vacuums on runtime, capacity and price.
How much does the BISSELL CrossWave OmniForce (3912E) cost in the UK?
The current lowest price tracked across UK retailers is £144.94, aggregated by idealo.co.uk. A separate UK listing shows an official RRP of £399.99 for the same model, so actual retail prices can vary considerably — check current listings before buying.
Does the CrossWave OmniForce (3912E) have a HEPA filter?
This isn't confirmed. Retailer listings for this model disagree — one describes a HEPA filter, another a cloth filter — and BISSELL's own product page doesn't clarify the filter type, so treat this as unverified.
How long does the battery last and how long does it take to charge?
Runtime is up to 30 minutes on standard PowerVac or PowerMop settings, or about 18 minutes in Turbo Mode. A full charge takes around 4 hours.
Can the CrossWave OmniForce be used on carpets?
No. It's designed for hard floors and tile, listed under multi-surface hard flooring rather than carpet compatibility.
Is the CrossWave OmniForce self-emptying?
No. It has an automatic self-cleaning cycle run through its charging/storage dock, which cleans the brush roll and internals, but it does not empty the dirty water tank automatically.
What's included with the BISSELL CrossWave OmniForce (3912E)?
The package includes a charging/storage dock, a trial-size bottle of BISSELL Multi-Surface cleaning solution, and a hair strainer.
