Best Cordless Vacuum Under £150 UK 2026 — Shark vs Dyson vs Dreame
The cordless vacuum market has moved fast. What cost £300+ a few years ago, Shark and Dreame now do for under £150. Here's what actually matters when you're choosing, and which ones are worth your money right now.
Three things to check: suction in Air Watts (100AW+ is the target), real battery life — not the marketing number, the actual one — and whether the mini motorised sofa tool comes included or costs extra. That attachment matters more than people expect; it's what actually gets pet hair out of upholstery.
🥇 Best Value: Shark IZ381UK Cordless
🏆 MOST POPULAR UNDER £150
We Recommend: 5/5 — the closest thing to Dyson performance at half the price
Shark's PowerPro/FloorDetect range has built a genuinely loyal following in UK reviews, and the IZ381UK is why. Solid on carpet and hard floors, with FloorDetect technology that automatically adjusts brush-roll speed for the surface, and a self-cleaning brush-roll that helps with pet hair. Lightweight enough that stairs aren't a chore. Check the listing for exact runtime and included tools, as these vary slightly by bundle.
- Floor detection: Automatically adjusts to carpet or hard floor
- Brush-roll: Self-cleaning, reduces hair wrap
- Best for: Mixed flooring homes, pet owners

⚡ MOST POWERFUL UNDER £150
We Recommend: 5/5 — the best raw suction at this price point
Dreame is the brand savvy buyers started noticing around 2024, and the T20 is the reason. 150AW — more than a Dyson V12 — for regularly under £150. The trade-off is battery life sits a bit shorter than the Shark on max power mode, so if you've got a bigger house, plan your run accordingly.
- Suction: 150AW
- Battery: Up to 70 minutes
- Best for: Carpet-heavy homes, maximum suction priority

⚠️ HONEST VERDICT
Honest verdict: the V8 is the only Dyson worth considering at this price
It dips under £150 on sale occasionally. Capable, but several generations old now, and Shark and Dreame have genuinely caught up on performance for less money. At full price it's not good value — we'd say only buy it if you find it heavily discounted and specifically want the Dyson name.
