Our verdict
Shark is the main brand that skips disposable bags. You tip the base bin into the rubbish instead, which saves money over time but is a little messier. Shark says the bin holds up to 60 days of debris, and the mop and water refill make it a full 2-in-1 package.
What we like
- No bags to buy
- Widely available in shops
- Bagless base, so no bags to buy
- Base also refills the robot's water tank
- Often heavily discounted, especially in the UK
- Shares the core PowerDetect robot with pricier models
What to know
- Vacuum Wars rated its obstacle avoidance below top flagships
- Emptying a bagless bin can release some dust
- Vacuum Wars rated its obstacle avoidance below the best flagships
- Cold-water pad wash, unlike the heated wash on the 2900 series
- Pads are dried at room temperature, so they take longer to dry
