650W 70-Minute vs CHEBIO: Two Stick Vacuums, Four Runtime Claims

Two cordless sticks in the same price band, and between them four different runtime figures. One listing is open about its test conditions; the other contradicts itself, and a third twin of the first states a different weight.

The two listings at a glance

Neither of these is a household-name brand. Both are cordless stick vacuums in the same price band, with the same HEPA filter claim and similar weights. What separates them is how many runtime figures each one states, and they are not the same number. The table gives each source separately.

Four runtime claims for two machines

The first listing states 70 minutes under one label and 1 hour and 5 minutes under another, which is 65. Its own bullet explains the figure: up to 70 minutes on low suction, tested with no load, at 25°C, on a new fully charged battery. That is the optimistic case on the kindest setting. The CHEBIO is more confusing. Amazon’s “Battery Life” field says 20 minutes and its “Runtime” field says 45. Its bullets claim up to 45 minutes of “fade-free” runtime, and our review adds that the 45 is on the low suction mode. We do not know which of the CHEBIO’s figures describes a normal cleaning session. What we can say is that the listing’s two fields differ by a factor of more than two.

Divide each runtime by weight, as a rough measure of how long you can clean per kilogram you carry. The 650W unit’s 70 minutes over 2.9 kilograms is 24.5 minutes per kilogram. The CHEBIO comes to 19.8 minutes per kilogram on its 45-minute claim and 8.8 on its 20-minute field. Which of those applies decides whether the two are comparable or an order of magnitude apart. It is not a number to rely on, and it shows how the choice of which field to believe changes the answer.

The same listing, three times

The first product has a twin, or more than one. 3 listings in our catalogue carry the same title text, “650W”, “55KPA” and “70Mins”: their stated weights are 1.8 kg, not stated, 2.9 kg, and their stated runtimes 60 minutes, not stated, 70 minutes. A product whose weight is listed as 2.9 kilograms in one place and 1.8 in another is either two products or one with an unreliable listing, and the title text gives no way to tell. We cannot say whether the 650W unit on this page is the same machine as its twins. We compare it as its own listing describes it.

What the battery can and cannot do

The 650W listing gives a battery pack of eight 2,800 mAh cells at 29.6 volts. If the cells are in series, as the voltage implies, that is about 82.9 watt-hours. At 650 watts, the headline motor power, that pack would last about 7.7 minutes. A 70-minute runtime implies an average draw of about 71 watts, around 11 percent of the motor’s stated power. So the two numbers on the listing, 650 watts and 70 minutes, describe different modes: the first is a peak, the second a gentle low-suction setting, which matches the bullet that says the 70 minutes is on low suction with no load. The CHEBIO’s listing gives a wattage of 550 and no battery capacity in the rows we read, so we cannot run the same check on it.

The practical lesson is that a stick’s runtime and its power figure are never both available at once. The more a listing emphasises its motor wattage, the more of its stated runtime you should expect to give back as you turn the power up.

Two bullet lists that read alike

Set the two listings’ bullet points side by side and the designs are described in almost the same words. Both advertise a V-shaped brush to stop hair wrapping, both a self-standing body, both a HEPA filter, both a dust cup over a litre, and both a runtime in the forties or seventies measured on low suction. None of this proves a shared design, and we are not claiming one. It does mean that you cannot separate these two on features, only on the figures they state and on how consistently each states them, which is the reason this page spends its time on the runtime fields.

Suction: a unit that does not travel

The 650W listing states 55,000 pascals, or 55 kilopascals, and the title uses “55KPA”. Among the 23 stick vacuums in our catalogue, seven put a kilopascal figure in the title, between 40 and 55, one gives 40,000 pascals, one states 185 air watts and one a motor wattage. Four different units. A buyer cannot rank a kilopascal against an air watt against a motor wattage, and the stick class report covers it further. The CHEBIO states none of these, and its structured “Maximum Suction” field reads 0.4 meters, a length, which is meaningless.

Which suits which

What this comparison cannot tell you

We did not test either machine, so we cannot say which has the longer real runtime, whether the 55,000 pascals are felt on a rug, or how loud either is in a room. A runtime on low suction is not a runtime on carpet. For each in full, see our review of the 650W listing and our CHEBIO review.
