Unlimited 7 BSS711W

I got the bosch unlimited 7 for around 300-350eur... My budget kinda increased at the time of buying it. I don't regret it at all. I've been using it for around a month now and it's amazing.

The biggest limiting factor in all wireless vacuum is the battery. Hence only look for removable or replaceable battery. These batteries have two limitations 1 - Runtime 2 - Life (typically 700/800 cycles, just like cell phones) . Used once a year, thats 3 years of cleaning before you need a replacement battery. In this regard the Bosch is the best. They have an established line up of batteries (the same as the ones used in their power tools line up) so supply is guaranteed after 3 years. Can't say the same about other brands. I got unlimited 7. On full power the base battery pack runs for 5 mins and at lower power for 20 odd mins. I purchased extra battery pack (double capacity 💪) now my runtime is 3 times. Charging is also sorted with bosch. You can buy a dedicated charger id required. Coming to robo vacs - They are an add on. Not a full replacement for jhaadu or Hand held wireless vac. Much less suction power. I have that as well - it runs on a schedule and helps keep the house dust free

Well, I've just tried: - Bosch 18V (green not blue). - Karcher vacuum cvh3. - Nilfisk VU200. The first two were useless; the VU200 is still a bit useless TBH, but at least it gets dust. Not leaves though. My next tries were going to be a Bosch Ultimate 10/Miele HX/Dyson v12, or a Metabo 18V (I already have their batteries), or a 18V blue Bosch. An extension cord is frankly probably the best.

Go to reviews of stick vacuums, find the most reputable brand with the best battery life, most suction power, largest dirt holder and try find one with a detachable hand held option as well, but make sure it's in your price range. I ended up with a Bosch and it's great, will get another Bosch if this ever dies, 5 years strong. 

Bought a Bosch one. The first one we got was a dud, the main switch failed after a week. Got a replacement and it's been great, I don't think we've used a larger vacuum cleaner since then.
