Bosch Flexxo Series 4 Cordless Vacuum Covers 220 m² a Charge

Bosch published a press release on 26 August 2026 detailing the Flexxo Series 4, a cordless stick vacuum the company calls “its most powerful freestanding cordless vacuum cleaner to date.” The headline figure, repeated on Bosch’s own live product page, is coverage of up to 220 square metres on a single battery charge, drawn from a runtime Bosch rates at up to 60 minutes.

What’s actually new about the Flexxo Series 4?

The vacuum is a 2-in-1 design: a push-button conversion turns the stick vacuum into a handheld unit for spot cleaning, car interiors or furniture. Bosch has built two accessories directly into the device body rather than requiring separate storage: an extendable crevice tool for reaching high ceilings and tight corners, and a 2-in-1 nozzle for furniture and upholstery. The AllFloor Power Nozzle also carries a bright LED light, meant to show up dust and debris under furniture or in dim corners that a shopper might otherwise miss.

Three power modes are available: Eco, Turbo, and a new Auto mode that Bosch says “automatically adjusts the suction power and runtime to the surface,” rather than leaving the shopper to switch modes manually between carpet and hard floor.

What does 220 m² mean for a real home?

A typical German apartment runs well under 100 square metres, so Bosch’s 220 m² figure describes several full passes through an average home before a recharge is needed, not a one-room limit. That said, this number comes from Bosch’s own testing and describes charge capacity under the conditions Bosch used, not an independently verified figure for every household’s mix of carpet, rugs and hard flooring.

The dust pickup claim is more tightly scoped: Bosch states “more than 99.9 percent” dust pickup, but its own footnote specifies this was “measured in turbo mode on hard floors with crevices,” tested to standard EN IEC 62885-4:2020/A1:2023. That is a turbo-mode, hard-floor result, not a blanket guarantee across carpet, pet hair or every cleaning mode.

How is the vacuum built for handling?

Bosch says more than 70 percent of the unit’s weight sits at the bottom of the device, which the company positions as easing one-handed control during use. The same low center of gravity lets the vacuum stand upright unsupported when paused mid-clean, useful for anyone stopping to move a chair or answer the door without hunting for somewhere to lean it. A colored light ring on the device shows battery status at a glance, so a shopper can see remaining charge without checking a separate display.

What’s the practical takeaway for a shopper?

Bosch has not disclosed a price for the Flexxo Series 4 in either the press release or its product page, so any figure circulating elsewhere should be treated as unconfirmed until a retailer lists it. The four launch colors, White, Grey, Steel Sky Blue and Florence Green, have been available since July 2026 according to Bosch’s own text, meaning this release is a formal write-up of a product already shipping rather than a future promise. Shoppers comparing it against other cordless sticks should watch for an official price and for independent testing of the 220 m² and 99.9% figures once retail units are more widely reviewed.
